TATE, Circuit Judge:
The sole issue before this court is whether an employee injured while performing marine petroleum exploration and extraction work aboard a drilling vessel located offshore but on state territorial waters is engaged in “maritime employment” within [1036]*1036the meaning of section 2(3) of the Longshoremen’s and Harbor Workers’ Compensation Act (“LHWCA” or “Act”), 33 U.S.C. § 902(3), as amended in 1972.
The question arises in a suit by an amphibious workman against a vessel defendant for damages resulting from injuries caused by the vessel’s negligence. The vessel defendant appeals the dismissal of its third-party demand against the workman’s employer for indemnification insofar as the injuries were caused by the employer’s fault. The precise issue is whether the employer is immune from the indemnification demand as an employer covered by the LHWCA; it is contended that the employer should be denied this immunity because its employee, although injured by maritime tort on a vessel in navigable waters, was nevertheless not in “maritime employment” and thus not covered by the Act.
A panel of this court, in a split decision, held that the work involved was indeed “maritime employment” within the meaning of the LHWCA. Boudreaux v. American Workover, Inc., 664 F.2d 463 (5th Cir. 1981). Rehearing en banc was granted. 664 F.2d 480 (5th Cir. 1982).
On rehearing, we reach the issue expressly reserved in Northeast Marine Terminal Co., Inc. v. Caputo, 432 U.S. 249, 266 n.25, 97 S.Ct. 2348, 2358 n.25, 53 L.Ed.2d 320 (1977): “whether Congress excluded people who would have been covered before the 1972 amendment; that is, workers who are injured on navigable waters as previously defined.”
For reasons to be set forth more fully, we find no Congressional intent to withdraw the coverage of the Act from those injured on navigable waters while engaged in what was considered as “maritime employment” for LHWCA purposes prior to the 1972 amendments.1 We, therefore, like the panel, affirm the district court’s determination in favor of the Act’s coverage of this maritime injury.
Facts and Procedural Context
The issue before us arises in the following factual and procedural context, which is more fully detailed in the panel opinion:
The plaintiff Boudreaux was injured over navigable waters in the course of his employment.2 His employer (“Aquatek”) was a contractor performing specialty mineral-production work on a drilling barge. Bou-dreaux sued the owner and operator (“AWI”) of the drilling barge for its negligent failure to provide him with a safe place to work.3
The district court dismissed a third-party demand by the defendant AWI (the owner and operator of the vessel) against Aqua-tek (the employer) for contribution or indemnity — in the event Boudreaux recovered against Aquatek — based on Aquatek’s al[1037]*1037leged contributing negligence. The district court thus upheld the contention of the employer that, since it was liable to Boudreaux for LHWCA compensation, it was protected from contribution or indemnity to the vessel by section 5(b) of the Act, 33 U.S.C. § 905(b) (quoted in note 9 below). This enactment, added by the 1972 revision, expressly provides that an employer of an injured workman covered by the Act shall not be liable to the vessel “directly or indirectly” for any injuries caused to its employee by the negligence of the vessel.
Thus, in the context of this litigation, the central issue — whether Boudreaux is covered by the LHWCA as amended in 1972, so as to be entitled to the compensation now being paid to him by his employer’s insurer (see note 3) — concerns whether a maritime employer, as so recognized for LHWCA purposes prior to the 1972 amendments, is to be denied the immunity from liability for contributing to negligence-caused injury to its employee,4 an immunity expressly intended by the 1972 amendments to be accorded to employers of persons entitled to LHWCA compensation because of injury in maritime employment. It also concerns whether the 1972 amendments withdrew coverage from pre-1972 maritime employees injured on the waters.
I. The 1972 Statutory Provisions
Prior to 1972 a single situs requirement of the LHWCA governed the scope of its coverage. That requirement limited coverage to workers whose “disability or death resulted] from an injury occurring upon the navigable waters of the United States (including any dry dock). ...” LHWCA of 1927, ch. 509, § 3(a), 44 Stat. 1426. The Supreme Court decided that a worker who in the course of his duty was obliged to go on navigable waters, however briefly or sporadically, and who suffered an injury while in that historically maritime locality, was covered by the pre-1972 LHWCA. Calbeck v. Travelers Insurance Co., 370 U.S. 114, 82 S.Ct. 1196, 8 L.Ed.2d 368 (1962). See Gilmore and Black, The Law of Admiralty, § 6-19 (esp. at 421-22) (2d ed. 1975); 4 Larson, The Law of Workmen’s Compensation, § 89.23(b) (esp. at 16-168, 169) and § 89.26 (1982).
Under the 1972 revision of the LHWCA, with its express intent to move the coverage landward (see II below), this simple test (generally, injury on the navigable waters) was modified. By the 1972 amendments to that Act, to be entitled to its benefits, a disabled employee must (a) be disabled as the result of “an injury occurring upon the navigable waters of the United States” (defined as also including adjoining areas), section 3(a) of the Act, 33 U.S.C. § 903(a)5 —the “situs” test; and (b) be engaged in “maritime employment” at the time of the injury, section 2(3) of the Act, 33 U.S.C. § 902(3)6 — the “status” test.
[1038]*1038These 1972 requirements for coverage under the Act have been at issue before the United States Supreme Court in three of its decisions. Two of them directly involved the issue of whether land-based employees, not covered by the LHWCA pri- or to the 1972 revision, were engaged in “maritime employment” at the time of their injuries: P. C. Pfeiffer Co. Inc. v. Ford, 444 U.S. 69,100 S.Ct. 328, 62 L.Ed.2d 225 (1979) and Northeast Marine Terminal Company, Inc. v. Caputo, 432 U.S. 249, 97 S.Ct. 2348, 53 L.Ed.2d 320 (1977). In both of these, coverage was upheld, affording the Act a liberal construction in view of its remedial purpose. Although the issue in the third decision, Sun Ship, Inc. v. Commonwealth of Pennsylvania, 447 U.S. 715, 100 S.Ct. 2432, 65 L.Ed.2d 458 (1980), was peripheral to the present, that decision nevertheless affords persuasive support to our ultimate conclusion that the 1972 revision was not intended to withdraw from amphibious workers beneficial rights to a worker’s compensation remedy previously permitted or enjoyed by them under the LHWCA prior to its 1972 revision.7
Caputo and Ford, the first two decisions, concerned land-based employees newly covered by the 1972 revision. They analyzed the 1972 amendments of the LHWCA as “replacing the single situs requirement [i.e., on navigable waters or their statutory equivalent] with a two-part situs and status standard.” Ford, supra, 444 U.S. at 73-74, 100 S.Ct. at 332; Caputo, supra, 432 U.S. at 264-65,97 S.Ct. at 2357. “To be eligible for compensation, a person must be an employee [status] as defined by § 2(3) [33 U.S.C. § 902(3)] who sustains injury on the situs defined by § 3(a) [33 U.S.C. § 903(a)].” Ford, 444 U.S. at 74,100 S.Ct. at 333. Situs turns on geography; status on the maritime-connected nature of the job. Id., 444 U.S. at 73-83, 100 S.Ct. at 333-37; Caputo, 432 U.S. at 265, 97 S.Ct. at 2358-63. Thus, both the status requirements, as defined by section 902(3), based on the nature of the job, and the situs requirements, as defined by section 903(a), based on geography, must be satisfied before the LHWCA can apply. Ford, 444 U.S. at 73-74, 100 S.Ct. at 332-33 (1979); Caputo, 432 U.S. 265, 97 S.Ct. at 2357.
We must note, however, that the issue as to “maritime employment” in Caputo and' Ford was with regard to land-based employees on the expanded waterfront situs of compensable accidents added by the 1972 amendment, as to whom the “maritime employment” test was designed to confine the remedy to employees in maritime-connected industries and to exclude from coverage non-maritime employees within the expanded shoreward zone. See legislative purposes in II below. The Court was there not concerned with employees injured on the actual navigable waters, who were at the time of the 1972 revision already considered to be in maritime employment for purposes of the LHWCA. (Indeed, in Caputo, the Court expressly noted that its opinion did not concern persons covered before the 1972 amendment who were injured on navigable waters. 436 U.S. at 266 n.25, 97 S.Ct. at 2358 n.25.)
It is conceded that the present injured worker, Boudreaux, was engaged in employment at the time of the accident that was compensable under the LHWCA prior to the amendment as occurring on the navigable waters. See Calbeck v. Travelers Insurance Company, supra. We have examined the legislative history and purposes of the 1972 revision (see II below) and the jurisprudential context in which it occurred (see III below), and we find no intention to dilute the pre-1972 meaning of “maritime employment”, with regard to employees actually injured on navigable waters, as including all employees required to work on such waters as part of their duties. See, e.g., Nalco Chemical Corporation v. Shea, [1039]*1039419 F.2d 572 (5th Cir. 1969). Thus, we will conclude, an employee injured on the waters in the course of his employment satisfies the 1972 revision’s “maritime employment” test, because employment on the water is “maritime employment” within the meaning of the LHWCA both before and after its 1972 revision. It therefore satisfies (when injury occurs on the waters) the 1972 “status” test as well as the “situs” test.
We must note here, by way of limitation, that no pre-1972 LHWCA case that we could discover involved the coverage of a person whose employment took him merely transiently or fortuitously to a maritime locus where he was injured, where otherwise except for this isolated incident his employer’s business was both land-based and unconnected with maritime-related employment.8 We express no opinion as to coverage of such a person, an issue not posed by the facts before us.
Before turning to the legislative purposes of the 1972 revision of the Act, we must note the approach established by the Supreme Court in its opinions. This approach to construction of the 1972 revision should, we think, guide judicial interpretation of the changes in the Act accomplished by that revision.
With regard to the landward extension of coverage, the Court stated that the “language of the 1972 Amendments is broad and suggests that we should take an expansive view of the extended coverage,” Capu-to, supra, 432 U.S. at 268, 97 S.Ct. at 2359, and that the decision to focus on the nature, not location of employment “also serves the broader congressional purpose of expanding coverage. Congress intended to apply a simple, uniform standard of coverage.” Ford, supra, 444 U.S. at 83-84, 100 S.Ct. at 338. Caputo stressed that this “remedial legislation ‘must be liberally construed in conformance with its purpose, and in a way which avoids harsh and incongruous results.’ ” Id. The third post-1972 decision, Sun Ship, supra (to be discussed more fully in VI below), involved an attempt, similar to the present, to construe the expanded coverage provisions of the 1972 revision as likewise somehow having the effect of overruling interpretations of the 1927 Act that were beneficial to covered employees.
In rejecting the effort to deduce such an intent from the amendments (that were designed to expand coverage), the Court found to be significant, and indeed determinative, the absence in the legislative history of the slightest intimation of any intent to affect prior jurisprudential interpretations •with respect to pre-existing coverage afforded by the Act to employees injured in waterfront and seaward accidents. 447 U.S. at 719-22, 100 S.Ct. 2436-37.
II. Legislative Purposes and History of 1972 Amendments
In 1972, the Congress amended the LHWCA of 1927, P.L. 92-576, 86 Stat. 1251, Longshoremen’s and Harbor Workers’ Compensation Act Amendments of 1972. The expansion of coverage landward, and the consequent addition of the “maritime employment” requirement, were merely part of this 1972 revision, described by Caputo as “the first significant effort to reform the 1927 Act and the judicial gloss that had been attached to it.” 432 U.S. at 261, 97 S.Ct. at 2356. As there stated, Id.:
[1040]*1040The main concern of the 1972 Amendments was not with the scope of coverage but with accommodating the desires of three interested groups: (1) shipowners who were discontented with the decisions allowing many maritime workers to use the doctrine of “seaworthiness” to recover full damages from shipowners regardless of fault; (2) employers of the longshoremen who, under another judicially created doctrine, could be required to indemnify shipowners and thereby lose the benefit of the intended exclusivity of the ■ compensation remedy; and (3) workers who wanted to improve the benefit schedule deemed inadequate by all parties.
To achieve the first two of these objectives, the final enactment provided, inter alia, (1) that the liability of the vessel was limited to those injuries caused by negligence and “shall not be based upon the warranty of seaworthiness,” and (2) “that the employer [of the covered worker] shall not be liable to the vessel for such [damages caused by vessel negligence] directly or indirectly.” Section 5(b), 33 U.S.C. § 905(b), as added by the 1972 amendments, P.L. 92-576, § 18.9
The legislation was enacted after committees of each House submitted full reports, each summarizing the general purposes of the legislation and containing a section by section analysis of the changes provided. Senate Report No. 92-1125, 92d Congress, 2d Session [hereinafter cited as “S.Rep.,” followed by page number]; House Report No. 92-1441, reprinted in [1972] U.S. Code Cong. & Ad.News 4698 [hereinafter cited as “H.Rep.,” with USCAN page number]. For instance, with regard to the section 905(b) changes, the reports specifically stated the intention to eliminate any unseaworthiness remedy against the vessel afforded longshoremen and other non-seamen working on board a vessel, and to eliminate any liability of their employer to the vessel for their own breach of duty contributing to the accident. S.Rep. at 2, 8-12, 25; H.Rep. at 4699, 4701-05, 4719. It is also of note that these legislative reports, in stating the reasons for the changes, specifically identify the Supreme Court decisions intended to be legislatively overruled, such as Ryan Stevedoring Co., Inc. v. Pan-Atlantic Steamship Corp., 350 U.S. 124, 76 S.Ct. 232, 100 L.Ed. 133 (1956) and Seas Shipping Co. v. Sieracki, 328 U.S. 85, 66 S.Ct. 872, 90 L.Ed. 1099.10
We now turn specifically to the 1972 legislative revision of section 2(3), 33 U.S.C. § 902(3), quoted at note 6, and of section 3(a), 33 U.S.C. § 903(a), quoted at note 5. The former, it will be recalled, added the “maritime employment,” or status, requirement for employees to be covered by the Act; the latter broadened coverage shoreward, to shoreside areas adjacent to navigable waters.
To accommodate the broadened shoreside situs, the former definition of “employer,” section 2(4), 33 U.S.C. § 902(4) was amended to broaden the definition of a maritime-employment employer. Before the 1972 [1041]*1041amendment, such an employer was defined with reference only to whether some of his employees worked, “in whole or in part, upon the navigable waters of the United States (including any dry dock).” After the amendment, the employer was defined as including the employer of those in maritime employment who worked, in whole or in part, upon the expanded shoreside areas as well as upon the navigable waters. As will be shown, because before 1972 the employee’s work upon the navigable waters had been the simple test of maritime employment (see III below), a change in the definition of an “employee,” section 2(3) was required in order to affirmatively, define which employees in the expanded shoreside situs were now covered.11
These changes are interrelated. As the Supreme Court observed in Caputo, whereas before the 1972 amendments, “so long as the work-related injury occurred on navigable waters and the injured worker was not a member of a narrowly defined class,12 the worker would be eligible for federal compensation provided that his or her employer had at least one employee engaged in maritime employment”; however, “with the definition of ‘navigable waters’ expanded by the 1972 Amendments to include such a large geographical area, it became necessary to describe affirmatively the class of workers Congress desired to compensate.” 432 U.S. at 264, 97 S.Ct. at 2357.
The reasons for the broadening of coverage to the shoreside areas by the section 3(a) amendment are well-documented in the legislative reports: “[Cjoverage of the present Act stops at the water’s edge; injuries on land are covered by State Workmen’s Compensation laws. The result is a disparity in benefits payable for death or disability depending on which side of the water’s edge and in which State the accident occurs. To make matters worse, most State Workmen’s Compensation laws provide benefits which are inadequate. * * ” S.Rep. at 12.13 In explaining the broaden[1042]*1042ing of coverage to extend to shoreside areas adjacent to navigable waters, the report stated: “The Committee believes that the compensation payable to a longshoreman or a ship repairman or builder should not depend on the fortuitous circumstance of whether the injury occurred on land or over water. ... The intent of the Committee is to permit a uniform compensation system to apply to employees who would otherwise be covered by this Act for part of their activity.” S.Rep. at 13. The House report sets forth identical views in substantially similar language. H.R. at 4707-08.
The reason for the addition, by the 1972 amendment to section 2(3), of the “maritime employment” (or “status”) requirement for coverage is not as explicit. Both legislative reports do state in identical language, in apparent reference to this change: “The Committee does not intend to cover employees who are not engaged in loading, unloading, repairing, or building a vessel, just because they are injured in an area adjoining navigable waters used for such activity... . Likewise the Committee has no intention of extending coverage under the Act to individuals who are not employed by a person who is an employer, i.e., a person at least some of whose employees are engaged, in whole or in part in some form of maritime employment.” S.Rep. at 13; H.Rep. at 4708 (emphasis supplied). Nevertheless, in the section by section analysis by which the legislative reports explain the reason for the changes, it becomes manifest in our opinion that the 1972 change in definition of an “employee,” section 2(3), was not intended to withdraw coverage from those previously considered to be in “maritime employment” for purposes of LHWCA coverage.
The 1972 revision originated as Senate Bill 2318. The Senate committee draft of an amended definition of “employee,” section 2(3) of the Act, was enacted by both Houses without change. In explaining the change in definition, the Senate committee report specifically noted that the new definition “does not exclude other employees traditionally covered” (emphasis supplied).14 S.Rep. at 16. The House committee report, although less explicit, states the new definition “includes any employee engaged in maritime employment, any longshoreman or other person engaged in longshoring operations, and any harborworker (including any ship repairman, shipbuilder, and shipbreaker)” (emphasis supplied).15
These committee reports of legislative purpose thus do not reflect any intention to withdraw the Act’s coverage from injuries to workmen, such as Boudreaux, injured on navigable waters in the course of employment with an employer at least some of whose employees worked in whole or in part on navigable waters. In particular, the legislative reports do not question or even refer to the holding of Calbeck, supra, that the Act’s coverage extended to “all injuries sustained by employees on navigable waters,” 370 U.S. at 124, 82 S.Ct. at 1202— “a significant omission in light of the care which the [committee] reports took to identify Supreme Court cases to be overturned .. . . ” See Sun Ship, Inc., supra, 447 [1043]*1043U.S. at 722, 100 S.Ct. at 2437. It is fair to say, we think, that a reading of the legislative reports, both overall and with specific reference to the “maritime employment” status test newly provided by the 1972 amendment to section 2(3), did not contemplate disturbing the previous Calbeck characterization of LHWCA-covered maritime employment as including amphibious workers injured on navigable waters.16
In 1962, Calbeck ended thirty-five years of confusing and unworkable judicial interpretations by its simple test that the Act covered all injuries on the navigable waters of employees whose employers employed one or more workers to labor on navigable waters. See Sun Ship, supra, 447 U.S. at 718,100 S.Ct. at 2435. The 1972 legislative committee reports reflect no dissatisfaction with this rule, and it is not readily credible that the previous forty-five years of judicial interpretations culminating in Calbeck and its progeny were intended to be legislatively altered without any mention of this drastic change to restrict coverage of the Act.
We are reenforced in this view, not only by the silence of the legislative reports as to such an intent, but by the consistent explanation for the new provisions as “an extension of coverage to shoreside areas,” S.Rep. at 12, H.Rep. at 4707 (emphasis supplied). The Senate Report in its “Summary” of the proposed legislation identifies its remedial purposes as “to upgrade benefits” and to “extend coverage to protect additional workers,” S.Rep. at 1 (as well as to “resolve the longstanding dispute over third-party actions by injured longshoremen” by abolishing (see text at note 10) the unseaworthiness remedy and the vessel-indemnity against stevedores, S.Rep. at 2). The thrust of the summary is that the legislation was designed to broaden coverage and increase benefits.17 We cannot find that Calbeck’s well-accepted construction of the Act as covering injuries on navigable waters was silently overruled by a remedial statute designed to broaden coverage and “framed out of solicitude for the workers.” Sun Ship, Inc., 447 U.S. at 726,100 S.Ct. at 2439. To do so, as the Court observed in a similar context, “would blunt the thrust of the 1972 amendments, and frustrate Congress’ intent to aid injured maritime laborers.” Id.
III. Jurisprudential Context of 1972 Amendments to the Act
The jurisprudential context in which the 1972 amendments to the Act were enacted makes it plain that a person who suffered an injury that occurred on navigable waters, such as the present plaintiff Bou-dreaux, was considered to be in “maritime employment” for purposes of the Act. The Court has quite recently summarized this jurisprudential context. See Ford, supra, 444 U.S. at 73, 100 S.Ct. at 332, and Sun [1044]*1044Ship, Inc., supra, 447 U.S. at 718-19, 100 S.Ct. at 2435-36.
As succinctly stated in Ford, id.:
The pre-1972 Act was simply an effort to fill the gap in workmen’s compensation coverage created by this Court’s decision in Southern Pacific Co. v. Jensen, 244 U.S. 205, 37 S.Ct. 524, 61 L.Ed. 1086 (1917), which held that state compensation systems could not reach longshoremen injured seaward of the water’s edge. A single situs requirement in § 3(a) of the Act governs the scope of its coverage. That requirement limited coverage to workers whose “disability or death resulted] from an injury occurring upon the navigable waters of the United States (including any dry dock). . .. ” Longshoremen’s and Harbor Workers’ Compensation Act of 1927, ch. 509, § 3(a), 44 Stat. 1426. In light of Jensen and the limited purpose of the Act, the situs test was understood to draw a sharp line between injuries sustained over water and those suffered on land. Thus, in Nacire-ma Operating Co. v. Johnson, 396 U.S. 212, 218-220, 90 S.Ct. 347, 351-352, 24 L.Ed.2d 371 (1969), this Court held that the Act did not extend to injuries occurring on a pier attached to the land. Although the Court recognized that inequities might result from rigid adherence to the Jensen line, the Court concluded that “[t]he invitation to move that line landward must be addressed to Congress, not to this Court.” Id., [396 U.S.,] at 224, 90 S.Ct. at 354.
. Congress responded with the Longshoremen’s and Harbor Workers’ Compensation Act Amendments of 1972 (1972 Act).
The intermediate states of jurisprudential development of the coverage issue between Jensen and Nacirema Operating Co. v. Johnson, supra, are described in Sun Ship, 447 U.S. at 718, 100 S.Ct. at 2435.
[T]he Court began to narrow the Jensen doctrine by identifying circumstances in which the subject of litigation might be maritime yet “local in character,” and thus amenable to relief under state law. Western Fuel Co. v. Garcia, 257 U.S. 233, 42 S.Ct. 89, 66 L.Ed. 210 (1921); Grant Smith-Porter Ship Co. v. Rohde, 257 U.S. 469, 42 S.Ct. 157, 66 L.Ed. 321 (1922). And, in 1927, Congress was finally successful in extending a measure of protection to marine workers excluded by Jensen by enacting a federal compensation law — the Longshoremen’s and Harbor Workers’ Compensation Act, 33 U.S.C. § 901 et seq....
Federal and state law were thus linked together to provide theoretically complete coverage for maritime laborers. But the boundary at which state remedies gave way to federal remedies was far from obvious in individual eases. As a result, the injured worker was compelled to make a jurisdictional guess before filing a claim; the price of error was unnecessary expense and possible foreclosure from the proper forum by statute of limitations. Davis v. Department of Labor, 317 U.S. 249, 254, 63 S.Ct. 225, 228, 87 L.Ed. 246 (1942). After a decade and a half during which there had not been formulated “any guiding, definite rule to determine the extent of state power in advance of litigation,” id., at 253, 63 S.Ct., at 227, the Court determined that the border between federal and state compensation schemes was less a line than a “twilight zone,” in which “employees must have their rights determined case by case ...” id., at 256, 63 S.Ct., at 229. Within this zone, Davis effectively established a regime of concurrent jurisdiction.
Calbeck v. Travelers Insurance Co., 370 U.S. 114, 82 S.Ct. 1196, 8 L.Ed.2d 368 (1962), further overlapped federal and state law coverage for marine workers. Calbeck held that the LHWCA comprehended “all injuries sustained by employees on navigable waters,” id., at 124, 82 S.Ct., at 1202, without regard to whether the locus of an event was “maritime but local,” and hence within the scope of state compensations provisions.18
[1045]*1045Thus, as summarized by Sun Ship, 447 U.S. at 719, 100 S.Ct. at 2486:
Before 1972, then, marine-related injuries fell within one of three jurisdictional spheres as they moved landward. At the furthest extreme, Jensen commanded that nonlocal maritime injuries fall under the LHWCA. “Maritime but local” injuries “upon the navigable waters of the United States,” 33 U.S.C. § 903(a), could be compensated under the LHWCA or under state law. And injuries suffered beyond navigable waters — albeit within the range of federal admiralty jurisdiction — were remediable only under state law. Nacirema Co. v. Johnson, supra.
That all employment-related injuries on navigable waters, including those that were characterized as “maritime but local,” were considered to have been in maritime employment, can be seen not only from the decisions of the era, see, e.g., Nalco Chemical Corporation v. Shea, supra, 419 F.2d at 574,19 but also by considering that under the pre-1972 scheme of coverage (see note 11), as now, the Act applied only to employers whose employees were “employed in maritime employment, in whole or in part upon the navigable waters of the United States.” Section 2(4) of the Act, 33 U.S.C. § 902(4). And aside from its statutory meaning for purposes of the LHWCA, the term “maritime employment” includes even in a nontechnical, general sense, employment upon the navigable waters.20
Under the pre-1972 jurisprudence, thus, an injury in “maritime employment” included, for purposes of the Act, all work injuries of amphibious workers on navigable water. Given this accepted pre-1972 meaning of the term for purposes of the Act, then within the intention of the 1972 amendments an amphibious worker injured on the navigable waters simultaneously meets both the “situs” and the “status” (occupational) tests. As earlier noted, the legislative purpose of adding the “maritime employment” test was to limit the Act’s coverage in the newly extended shoreside areas to those employees who were injured therein in the course of maritime-related employment. We can find no sign in the legislative history or purpose that the Congress intended by the 1972 amendments to change the prior well-accepted understanding that an injury on navigable waters was compensable as being in “maritime employment.”
IV. Post-1972 Commentary and Jurisprudence
Following adoption of the 1972 amendments, the new “maritime employment” status test has arisen for application in two situations. The bulk of the litigation concerns application of the test in the new extended shoreside application, as in Caputo (1977) and Ford (1979), which we have discussed at I above. A substantial minority of the decisions of the lower courts, however, attempted to apply a status test in some formulation to work-related injuries on navigable waters — i.e., to those considered as in “maritime employment” prior to the 1972 revision — , although in all but three or four instances (only one from this circuit), coverage was nevertheless upheld.
[1046]*1046Preliminarily, we note that the majority view of the commentators, including the highly respected Gilmore and Black, is that the amended Act does not exclude coverage from anyone who would have been covered under the original Act; and thus that any injury upon the navigable waters is still compensable.21 This view has also had the consistent support of the director of the Office of Workers’ Compensation Programs, the administrative agency charged with enforcement of the LHWCA.22 This court has held that the director’s views are entitled to deference.23 These authorities rely primarily on the legislative history and the remedial purposes of the 1972 amendments in support of the proposition that the amended Act does not exclude anyone who would have been covered prior to 1972.
In the adjudicative context, at least prior to 1979, it appeared that this position would be widely accepted. It was adopted by the Benefits Review Board (“BRB”), the entity created by the 1972 amendments to hear administrative appeals of LHWCA coverage disputes.24 Furthermore, this “no exclusion of those traditionally covered” doctrine was initially embraced by the courts in St. Ju-lien v. Diamond M Drilling, 403 F.Supp. 1256 (E.D.La.1975), and Fusco v. Perini North River Associates, 601 F.2d 659 (2d Cir. 1979), vacated, 444 U.S. 1028, 100 S.Ct. 697, 62 L.Ed.2d 664 (1980) (“Fusco I”).
The first decision to take a more restrictive view of the LHWCA coverage of injuries on the actual water was Weyerhaeuser Co. v. Gilmore, 528 F.2d 957 (9th Cir. 1975), cert. denied, 429 U.S. 868, 97 S.Ct. 179, 50 L.Ed.2d 148 (1976). Weyerhaeuser rejected the BRB’s construction of the 1972 amendments as not affecting the pre-1972 construction of maritime employment that included all work-injuries on the water. Instead, the Ninth Circuit held that the term “maritime employment” means that the employment “must have a realistically significant relationship to ‘traditional maritime activity involving navigation and commerce on navigable waters.’ ” 528 F.2d at 961 (a test it educed from Executive Jet Aviation, Inc. v. City of Cleveland, 409 U.S. 249, 93 S.Ct. 493, 34 L.Ed.2d 454 (1972) — a decision we find inapposite for this purpose, for reasons to be stated in V below). Thus, under the Weyerhaeuser test, some employees whose injuries would have been covered under the pre-1972 Act would not be entitled to LHWCA coverage. The Weyerhaeuser court relegated Calbeck and the other pre-1972 decisions “to limbo,” based on the conclusion that the 1972 amendments “radically changed the basis for an employee’s entitlement to federal compensation.” 528 F.2d at 960.
In recent years, the more restrictive Wey-erhaeuser test has been accepted, or at least given lip service, by many courts, including [1047]*1047this court. Ironically, the case that proved to be the catalyst for the widespread acceptance of the restrictive Weyerhaeuser view regarding accidents upon the actual water was the Supreme Court’s decision in Ford, supra, a case that actually expanded LHWCA shore-side coverage.
Subsequent to Ford, over the dissent of three justices, the Supreme Court vacated and remanded the Second Circuit’s Fusco I decision for reconsideration in light of Ford. Perini North River Associates v. Fusco, 444 U.S. 1028, 100 S.Ct. 697, 62 L.Ed.2d 664 (1980). On remand, despite the fact that Ford took a very expansive view of LHWCA coverage, and despite the fact that Ford did not so much as mention the Weyerhaeuser “significant relationship to navigation or commerce on navigable waters” test for determining “maritime employment,” the Second Circuit found that Ford had “rendered untenable” its holding in Fusco I. Noting Ford’s conclusion that the term “maritime employment” is an occupational concept, based on the nature of a worker’s activities, the Second Circuit read Ford “as precluding any application of the LHWCA as amended in 1972, to an employee whose activities do not bear a significant relationship to navigation or to commerce on navigable waters.” Fusco v. Perini North River Associates, 622 F.2d 1111, 1112-13 (2d Cir. 1980), cert. denied25 449 U.S. 1131, 101 S.Ct. 953, 67 L.Ed.2d 119 (1981) (“Fusco II”). The Fusco II court noted that such a reading was consistent with the construction of the term “maritime employment” given by the Weyer-haeuser court, and with the position of the BRB, which, after having been reversed by the Ninth Circuit in Weyerhaeuser, had overruled its previous decisions that had held that the 1972 amendments did not in any way reduce the traditional coverage of the LHWCA.
Since 1979, the Weyerhaeuser — Fusco II “realistically significant relationship to traditional maritime activity” test for determining whether an individual was engaged in “maritime employment” has frequently been employed by the courts, in eases involving accidents both on the seaward and shoreward sides of the Jensen line. In this circuit, the Weyerhaeuser test has been cited approvingly in several decisions of the court, in cases involving accidents both on the land and the water;26 nevertheless, LHWCA coverage was found in all of the cases.27 As might be expected from application of a test that requires determination case-by-case under the specialized facts of each instance, the Weyerhaeuser test — even though recovery has ultimately been upheld — has produced sharp disagreement as to whether under particular facts the on-water employment indeed had the talismanic “significant relationship.” 28
[1048]*1048It is of some significance to note that, despite the sometimes cumbersome methodology involved in the disputable borderline case-by-case application of the Weyerhaeuser “significant relationship” test, actually in only three decisions was coverage denied by it to a workman injured waterward of the Jensen line who would apparently have been covered by the pre-1972 Act under Calbeck: Weyerhaeuser itself, by the Ninth Circuit; Fusco II (but see note 25) by the Second; and, adhering to Fusco II, Churchill v. Perini North River Associates, 652 F.2d 255 (2d Cir. 1981), cert. granted,U. S. -, 102 S.Ct. 1425, 71 L.Ed.2d 647 (1982). (Also, although not employing the Weyerhaeuser rationale, one decision of this court denied coverage for an on-water accident of an oil field worker, who presumably would have been covered under Calbeck, on a basis subsequently disapproved by Ford and subsequent decisions of this circuit. Thibodaux v. Atlantic Richfield Co., 580 F.2d 841 (5th Cir. 1978).29
V. Distinction Between Shoreside and On-Water Injuries Insofar as Being in “Maritime Employment”
We have found no legislative intent to alter the previously accepted construction of the Act as considering employment on the navigable waters to be “maritime employment.” See II and III above. For employees injured in the course of such employment, no further examination into the relationship of their employment activities to “ ‘traditional maritime activity involving navigation and commerce on navigable waters,’ ” Weyerhaeuser supra, 528 F.2d at 961, is necessary, because by settled construction of the Act their duties necessarily constitute such maritime activity.
However, as we noted, see text supra at note 11, the 1972 expansion of situs to include shoreside areas required a different change both in the definition of “employer” to include those within the expanded situs and also in the definition of “employee” so as to exclude those employees injured in the expanded shoreside situs who were not engaged in maritime-related employment. As the legislative committee reports stated, the 1972 revision to include shoreside areas was not intended to cover employees “just because they are injured in an area adjoining navigable waters” or who were not “engaged, in whole or in part in some form of maritime employment.” S.Rep. at 13; H.Rep. at 4708.
[1049]*1049To delineate only those shoreside employees who were legislatively intended to be included within the coverage of the Act, the Weyerhaeuser or an equivalent maritime-relationship test may indeed be appropriate.30
Where we part company with Weyer-haeuser is in its application of such a test to those injured while working on navigable waters, construed for LHWCA purposes as being in maritime employment since Cal-beck. As earlier noted, to restrict this accepted statutory construction is to do so in the complete absence of any intent expressed in the legislative history to do so and, in fact, in the face of express statement by the legislative drafters that the new 1972 definition of employee afforded by the amended section 2(3) “does not exclude other employees traditionally covered.” S.Rep. at 16. See II above.
Weyerhaeuser derived its “significant relationship” test for coverage, 528 F.2d at 961, by direct quotation from Executive Jet Aviation, Inc. v. City of Cleveland, 409 U.S. 249, 93 S.Ct. 493, 34 L.Ed.2d 454 (1972). That decision is inapposite to the issue now before us. The sole issue in Executive Jet was whether there was federal jurisdiction over a suit for damages resulting from an airplane crash into navigable waters, and there the assertion of jurisdiction was based solely upon the provision of 28 U.S.C. § 1333(1) granting federal district courts jurisdiction of “[a]ny civil case of admiralty or maritime jurisdiction.” The Court emphasized that in flights between points in the continental United States, “which are principally over land, the fact that an aircraft happens to fall in navigable waters, rather than on land, is wholly fortuitous.” 409 U.S. at 266, 93 S.Ct. at 503. The Court held that
the mere fact that the alleged wrong “occurs” or “is located on” or over navigable waters ... is not of itself sufficient to turn an airplane negligence case into a “maritime tort.” It is far more consistent with the history and purpose of admiralty to require also that the wrong bear a significant relationship to traditional maritime activity. We hold that unless such a relationship exists, claims arising from airplane accidents are not cognizable in admiralty in the absence of legislation to the contrary.
409 U.S. at 2681, 93 S.Ct. at 504.
Executive Jet is thus entirely inapposite to the issues before us. Although the issue there and here each involved a determination of legislative intent in the utilization of the term “maritime,” two entirely different [1050]*1050statutes are concerned, each with different legislative histories and jurisprudential interpretations over the course of decades.31 Unlike Executive Jet, which involved no specific legislation addressed to the issue, here the LHWCA both in its 1927 enactment and its 1972 revision provided for coverage of injuries in “maritime employment” occurring “upon the navigable waters of the United States,” which the Court in Calbeck had interpreted to include all injuries in the course of employment upon the navigable waters. Finally, marine petroleum workers are not “fortuitously” located on the water, but are required to work there by the nature of their jobs, a substantial maritime relationship.
VI. No Intention to Reduce Prior Coverage of On-Water Injuries: The Contribution of Sun Ship
The rationale in Sun Ship, Inc. v. Pennsylvania, supra, supports our conclusion that the legislative history of the 1972 amendments reflects no intention to disturb the prior Calbeck interpretation of the Act that work-injuries on navigable waters were incurred in maritime employment for purposes of the LHWCA.
The issue in Sun Ship was whether the shoreside extension of the Act’s federal compensation coverage displaced state workers’ compensation laws applicable to those on-land injuries, a concurrent state compensation remedy available under pre-1972 LHWCA interpretations to workingmen injured in “maritime but local” activities. The issue is the obverse of the present, which is: did the 1972 revisions reflect any intent to remove a federal compensation remedy formerly available to those amphibious workmen injured while working on navigable waters? Nevertheless, the issue is generically similar; as Sun Ship recounted, 447 U.S. 718-19, 100 S.Ct. at 2435-36 (quoted in III above), both the concurrent state-federal remedy for “maritime but local” workers, as well as the Calbeck holding that the LHWCA comprehended “all injuries sustained by employees on navigable waters,” 370 U.S. at 124, 82 S.Ct. at 1202, resulted after years of tortuous litigation attempting to solve the same problem:
Under the “maritime but local” doctrine, a state, instead of a federal, remedy was accorded a workman injured on navigable waters, if neither his general employment nor his activities at the time of the accident “had any direct relationship to navigation or commerce.” Grant Smith-Porter Co. v. Rohde, 257 U.S. 469, 475-76, 42 S.Ct. 157, 158, 66 L.Ed. 321 (1922). However, the state remedy would be disallowed — and the federal remedy was exclusive — if the Court found that the employment was “not [a] matter of purely local concern,” but instead had “direct relation to commerce and navigation.” Northern Coal & Dock Co. v. Strand, 278 U.S. 142, 144, 49 S.Ct. 88, 89, 73 L.Ed. 232 (1928). Sun Ship describes the uncertainties, hardships, and requirement for litigation by “jurisdictional guess,” 447 U.S. at 718, 100 S.Ct. at 2435, that resulted from the necessity on a case by case basis to determine whether an amphibious worker’s employment had sufficient “direct relation to commerce and navigation” so as to be compensable under the federal or the state remedies respectively. To solve this identical problem, concurrent state and federal remedies were recognized for “maritime but local” land-based employees (Davis, supra, discussed in III), while Calbeck held that all work-injuries on the navigable waters were compensable under the LHWCA “without regard to whether the locus of an event was ‘maritime but local,’ and hence within the scope of state compensation provisions.” Sun Ship, 447 U.S. at 718,100 S.Ct. at 2435.
[1051]*1051Sun Ship examined the legislative history and reports of the same 1972 amendments as are at issue before us. 447 U.S. at 719-725, 100 S.Ct. at 2436-39. Citing the complete absence of any reflected intent to abrogate the doctrines of Davis and Cal-beck, the Court held that the 1972 amendments could not fairly be understood as “resurrecting the jurisdictional monstrosity that existed before the clarifying opinions in Davis and Calbeck,” 447 U.S. at 719, 100 S.Ct. at 2436. The Court also noted that so to adopt the appellant’s position “would thrust employees into the same jurisdictional peril from which they were rescued by Davis and Calbeck v. Travelers Insurance Co.” 447 U.S. at 725, 100 S.Ct. at 2439 — a result that “would blunt the thrust of the 1972 amendments, and frustrate Congress’ intent to aid injured maritime workers” through this “remedial” legislation enacted “out of solicitude for the workers.” Id.
The issue in Sun Ship related to whether the pre-1972 concurrent state-federal remedy recognized by Davis had been diminished by the 1972 amendments. Nevertheless, Sun Ship’s reasoning, it seems to us, equally applies as to the generically similar issue before us, i.e., whether these same amendments have diminished CalbecWs pre-1972 recognition of all work-injuries on navigable waters as being in “maritime employment” for purposes of the Act — an interpretation complementary to the concurrent-remedy interpretation of the Act accorded by Davis, equally based upon the identical reasons of effectuating the certain and efficient administration of the compensation remedy afforded by Congress to amphibious workers by the Act.32
We, similarly to Sun Ship, can find no legislative intent expressed in the legislative history to override Calbeclds interpretation that injuries sustained at work on navigable waters were sustained in “maritime employment” within the meaning of the Act; in fact, the legislative history here indicates the contrary. See II above. We note that attempting to determine case by case whether an on-water injury occurs in an employment with a “realistically significant relationship to traditional maritime activity involving navigation and commerce on navigable waters,” as enunciated by Weyerhaeuser, supra, involves the same difficulties and disagreements in determinations (see, e.g., note 28), as did the unworkable case by case determination in the “maritime but local” test of whether the employment had a “direct relationship to navigation or commerce,” see Grant Smith-Porter v. Rohde, supra, that was rejected by Davis and Calbeck.. No more than was the Court in Sun Ship, are we willing to believe that in its 1972 remedial revisions the Congress intended — without the slightest sign of any intent to do so — to resurrect the “jurisdictional monstrosity” created by such a test of indeterminate content, terminated fully by the clarifying interpretations of Davis (1942) and Calbeck (1962).
One final note. We must be mindful that a primary intent of the 1972 amendments was not only remedial as to injured work[1052]*1052ers, by increasing their benefits and by extending coverage landward. Another principal purpose was to free maritime employers of indemnity claims by vessels on which their employees were injured, and thus to assure that an employer’s compensation liability under the Act “shall be exclusive and in place of all other liability” for an employment-related injury, section 905(a), 33 U.S.C. § 905(a). See text at notes 9 and 10 above. The express legislative intent was to immunize employers of amphibious workers injured on a vessel from indemnity claims, such as that herein asserted by the vessel-defendant by third-party demand against the plaintiff Bou-dreaux’s employer.
If we here determine that Boudreaux was not in “maritime employment” at the time of his injury on navigable waters, his employer is exposed to the vessel’s indemnity action, see Miller v. Central Dispatch, Inc., supra, 673 F.2d at 784, despite the undoubted and express intent reflected by the legislative reports and statutory language to exempt all maritime employers from such a claim. The legislative history reveals not the slightest intention other than that this freedom from indemnity claim granted by the 1972 amendments was intended to benefit all employers of amphibious workers injured on vessels, such as Boudreaux’s employer in the present instance. To withdraw coverage from Bou-dreaux and other amphibious workers injured on navigable waters is to expand their employers ’ exposure to such indemnity claims, as well as to vexatious suits on a case-by-case basis (including those based on unseaworthiness), using indefinite criteria to determine whether the employee’s injuries were or were not covered by the Act. As we stated in this context in Miller, supra,
This result would run contrary to the clear Congressional intent under the 1972 amendments to include maritime workers under the Act in exchange for eliminating the right to sue for unseaworthiness. Sun Ship, Inc. v. Pennsylvania, 447 U.S. at 724, 100 S.Ct. at 2438, 65 L.Ed.2d at 466. The LHWCA is to be liberally construed and in such a way as to avoid the jurisdictional dilemma which existed pri- or to the 1972 amendments. See Sun Ship, Inc. v. Pennsylvania, 447 U.S. at 719-21, 725-26, 100 S.Ct. at 2436-37,-2439, 65 L.Ed.2d at 462-64, 466-67.
673 F.2d at 784.
VII. Coverage Afforded Even Under the Weyerhaeuser Test
We further note that coverage of the Act is here afforded even under the Weyerhaeu-ser test- — i.e., that, even though the injury is sustained on the navigable waters, for an injured employee’s work-activity to be considered within the coverage of the Act as “maritime employment,” the employment activities must have a realistically significant relationship to traditional maritime activity relating to navigation or commerce on navigable waters. This is the conclusion reached by the panel decision herein, 664 F.2d at 464-66 (Part I), relying upon a holding under similar facts in Pippen v. Shell Oil Co., 661 F.2d 378 (5th Cir. 1981). In both of these decisions, oil-production specialty workers were injured at work on movable drilling barges (“vessels”). The situs test was unquestionably met, and the issue was whether these employees met the status or “maritime employment” test.
The substance of the reasoning in these decisions is set forth at Pippen, 661 F.2d at 383-84:
In the instant case, plaintiff Pippen was a wireline operator. At the time of his injury he was preparing to set packers for perforation. The function of the vessel on which Pippen was working was to drill gas wells; consequently, Pippen’s work was essential to the function of the vessel. More importantly, Pippen’s job was necessary to the completion of the offshore drilling process. As discussed above, to determine whether the status test is satisfied, it is necessary to examine the nature and purpose of the employee’s activities and to determine whether those activities had a realistically significant relationship to maritime navigation or commerce. The “significant relationship” [1053]*1053requirement can be met when the purpose of the employee’s activities is to facilitate maritime commerce. Since offshore drilling — the discovery, recovery, and sale of oil and natural gas from the sea bottom — is maritime commerce, it follows that the purpose of Pippen’s work was to facilitate maritime commerce. Since the purpose of Pippen’s work was to enable the vessel to perform its designated task — offshore drilling — and since the work was, in addition, directed at facilitating maritime commerce, we are compelled to conclude that the work performed by Pippen had a realistically significant relationship to maritime commerce. Thus, Pippen was engaged in maritime employment at the time of his injury.
Or, as summarized by the panel majority in Boudreaux, 664 F.2d at 466:
The ruling in Pippen is dispositive of the present issue. In the case before us, Boudreaux (like Pippen) was injured on navigable waters while performing wire-lining employment duties that were an integral or essential contribution to the mineral-production function of the vessel upon which he was working. The work performed thus “has a realistically significant connection to traditional maritime activity”, Pippen, supra, 661 F.2d at 385, so as to be “maritime employment” within the coverage of the LHWCA.
The jurisprudential expressions upon which these conclusions are reached are fully set forth by the cited opinions. We see no need to reiterate them here. Suffice it to say, they fully support the holdings in these cases that the injured employees involved met the “significant relationship” test of maritime employment enunciated by these decisions, and that therefore their injuries were within the coverage of the Act.
Some suggestion is made that contemporaneous 1972 legislative action (or rather inaction) indicates that Congress did not consider maritime oil-production workers to be covered by the Act, as amended in 1972. Reliance is placed upon Congress’s failure, after consideration, to enact the “Tower bill”, the “Marine Petroleum Workers’ Compensation Act of 1971”.33 However, assuming legislative intent could be deduced from Congress’s failure to enact related legislation, no such inference could be drawn here. The Tower bill was intended to extend LHWCA coverage to all marine petroleum extractive workers; its primary purpose, however, was to relegate to the LHWCA compensation remedy those oil workers assigned as “members of the crew” to movable barges and thus entitled to the greater damages afforded by the Jones Act, see Offshore Company v. Robison, 266 F.2d 769 (5th Cir. 1959)34 As the Senate committee hearings show, it was. conceded by both industry and labor witnesses that non-crew offshore oil workers were then entitled to LHWCA benefits if injured on navigable waters, or on fixed platforms on the outer continental shelf, and the effort of the bill was only to extend a similar coverage to oil-worker “crew” members on movable barges and to deny them the more generous Jones Act seaman remedy.35 If any inference as to Congressional intent is permissible from the circumstances surrounding non-enactment of the Tower bill, it is that Congress felt that no new legislation was required to afford LHWCA coverage to non-crew oil-workers injured on navigable waters, and that it did not wish to deprive “crew” oil-workers of their more lucrative Jones Act recovery.
[1054]*1054
Conclusion
For the reasons above stated, we conclude that the 1972 LHWCA amendments did not in any way diminish the traditional coverage of workers injured at work on navigable waters, who under the Act have been and are considered to be in “maritime employment.” Even were it required that the duties of a “maritime employee” require a “significant relationship to maritime commerce or navigation”, the plaintiff Bou-dreaux is nevertheless within the coverage of the LHWCA, because persons in the marine petroleum business who work on drilling vessels in navigable waters are engaged in employment significantly related to maritime navigation and commerce. Accordingly, we AFFIRM the judgment of the district court, which held that the third-party defendant (Boudreaux’s employer) was exempted from indemnifying the vessel party (defendant in Boudreaux’s suit, and third-party plaintiffs herein) by statutory provisions according this defense to employers covered by the Act.
AFFIRMED.
