Richard Hill was injured when he fell from the wall of a tank he was inspecting aboard the vessel the TEXACO ILLINOIS. Hill collected compensation payments from his employer, Evans Engineering, Inc. (Evans), an independent contractor, then brought suit against the vessel’s owner, Texaco, Inc. (Texaco). Hill charged the ship with negligence under § 905 of the Longshoremen’s and Harbor Workers’ Compensation Act (LHWCA), 33 U.S.C. § 905(b).

After a bench trial, the court awarded damages to Hill,
On January 17, 1975, Richard Hill began to climb the walls of a gasoline storage tank aboard the tanker the TEXACO ILLINOIS. Hill’s employer, Evans, was an independent contractor that Texaco had hired to determine the effect of rust on the thickness of the tank walls. January 17 was the third day that Evans had been conducting tests on the TEXACO ILLINOIS. Hill carried with him ultrasonic testing equipment to perform the tests. Because the tank had been drained of ballast water only three hours earlier, the tank was damp and slippery. The walls of the tank were also covered with loose rust. Hill ascended by standing on “stiffeners” — shelf-like projections from the tank walls. The stiffeners were also covered with rust. When Hill was approximately 30 feet above the bottom of the tank, a piece of rust on the stiffener on which he stood became loose, and Hill lost his footing. Because Hill wore *449 no safety belt or safety lines to break his fall, Hill fell to the tank floor. The fall resulted in heel and back injuries to Hill and a lawsuit against Texaco.
I.
The district court found that Hill was 20% negligent, that Evans, Hill’s employer, was 60% negligent, and that Texaco, the vessel owner, was 20% negligent. Under the rule of
Edmonds v. Campagnie General Transatlantique,
First, the district court found that Texaco knew that the sides of the walls were rusty and damp. The effect of rust on the tank walls was precisely what Evans had been hired to test. The dampness resulted from the recent discharge of ballast water from the tank, also well known to Texaco. Second, the court found that Texaco knew that to climb the walls of the tank without a safety line was dangerous. Third, the court found that Texaco knew that Hill was not using safety equipment despite both Hills’ and Evans’ appreciation of the danger of slipping on the wet, rusty stiffeners. On the basis of these three findings, the district court concluded that Texaco had a duty to step in and insist that Hill either use safety equipment or terminate the tests. 2
The linchpin of the district court’s reasoning is its factual finding that Texaco knew that Hill was not using safety lines when he began his spider-like climb up the walls of the tank. The district court made this finding as an inference from two pieces of evidence. First, the ship’s mate, Billy Yawn, testified that he saw the Evans personnel on deck before they descended into the tank and noticed that they had no safety equipment with them. From this, the court inferred that Yawn knew that Hill wore no safety lines when performing the tests. Second, because Evans had been working on the vessel for two days before the day of Hill’s fall, “this court infers that the captain and other officers of the Texaco Illinois who were on board the entire time Evans’ crew worked, knew or should have known the method and safety devices Evans’ crew used to test the metal thickness, at least by the end of Hill’s first day of work.”
A review of the record shows that Yawn, the ship’s mate, did not testify that he saw Hill climb the tank without safety equipment. Nor did Yawn testify that he saw the Evans’ personnel descend into the tank without such equipment. All Yawn said was that three hours before Hill’s fall, Yawn saw the Evans’ employees on deck and he noticed no safety equipment. This testimony does not permit the inference that Yawn knew that Hill was working below deck without safety equipment. Three hours elapsed between Yawn’s observations and the beginning of the test. What Yawn saw on deck provides no good indication of what transpired below deck three hours later. The district court’s inference to the contrary is clearly erroneous.
The district court also inferred that the ship had knowledge of the type of safety equipment used by Evans because Evans *450 had been working on the ship for two days prior to Hill’s fall. This inference lacks adequate foundation. There was no testimony that members of the ship’s crew participated in or supervised Evans’ work. Nor was there testimony that the ship asked Evans what safety equipment he used. The district court’s finding rests solely on the assumption that the simultaneous presence on the ship of Evans and the crew yielded knowledge of Evans’ methods.
On similar facts, we have previously rejected such a speculative leap. In
Stockstill v. Gypsum Transportation,
The district court also inferred that the vessel should have known what type of safety equipment Evans used. This inference presumes that the ship had some duty to supervise Evans’ performance of its work. As we shall see, however, the ship had no such duty.
Scindia Steam Navigation Co. v. De Los Santos,
The district court’s findings of fact, of course, are shielded against reversal unless “clearly erroneous.” Fed.R.Civ.P. 52(a);
United States v. United States Gypsum Co.,
II.
Our second inquiry is to determine if Texaco is liable to Hill even though it had no knowledge of the way the work was being carried out. We are guided in this quest by Scindia Steam Navigation Co. v. De Los Santos, supra, which the Supreme Court handed down after the district court decided this case. In Scindia, a longshoreman was struck and injured by sacks of wheat that fell from a pallet suspended by á defective ship’s winch. The stevedore had been using the winch for two days prior to the accident despite its malfunction. The longshoreman sued the ship under § 905(b) of the LHWCA.
The district court applied land-based negligence standards to the ship and held that the shipowner had no duty to supervise the stevedore’s work nor warn the longshoreman of open and obvious dangers. The district court therefore granted summary judgment for the vessel. The Court of Appeals for the Ninth Circuit reversed, holding that the ship had a duty of “reasonable care under the circumstances to protect the longshoremen against the danger,”
Scindia,
In
Scindia,
the Court articulated three general principles to govern the duties of a
*451
vessel towards the employees of a stevedore. First, before the stevedore begins his work, a shipowner must exercise care to make safe the portions of the ship that it turns over to the stevedore. In discharging this duty the ship may rely on the stevedore’s performing its task with reasonable care. The shipowner must also warn the stevedore of hidden unsafe conditions on the ship of which the ship is, or should be, aware.
Second, once the stevedore begins its operations, the shipowner has no general duty to supervise work or to inspect the area assigned to the stevedore, unless custom, contract, or law imposes such a duty on the shipowner. The shipowner need not monitor the stevedore’s operations; rather, the shipowner is entitled to rely on the stevedore’s expertise and reasonableness.
Third, the Supreme Court made an exception to the general absence of a duty of the shipowner to protect employees of the stevedore during cargo operations.
3
The duty arises when two conditions are fulfilled.
If
the shipowner becomes aware during the stevedore’s work that the ship or its gear poses a danger to the longshoremen, and
if
the shipowner also learns that the stevedore is acting unreasonably in failing to protect the longshoremen against the danger, then the shipowner acquires a duty to intervene and protect the longshoremen. The shipowner can have knowledge of a defect if the defect develops during the stevedore’s operations and the shipowner has actual knowledge, or if the defect exists at the outset and the ship “must be deemed” to have knowledge of it.

The rationale of
Scindia
is not limited to stevedoring operations. It clearly applies to any independent contractor and its harborworker employees covered by the LHWCA and working aboard ship. Applying
Scindia
to the facts of this case, we see no basis for imposing liability on Texaco. Hill’s injury occurred when the operations —here, an inspection of vessel tanks — were underway. Under
Scindia,
Texaco had no duty to oversee this work to make sure it was conducted safely. Texaco was entitled to rely on Evans’ expertise to perform his job with reasonable precautions. Evans, not Texaco, had a duty to require Hill to use safety equipment.
See
33 U.S.C. § 941;
Marler v. International Grain Corp.,
Moreover, the Scindia exception, which requires the vessel to protect a longshoreman or harborworker when the vessel knows of an unsafe condition and knows that the independent contractor is not adequately guarding the longshoreman or har-borworker against the danger, has no application here. Texaco, we have found above, had no knowledge that Evans was permitting Hill to climb the stiffeners without safety equipment. In the absence of such knowledge, Texaco was not negligent in failing to act. Thus, Texaco could be found liable only if it had negligently turned over to Evans an unsafe place to work, or failed to warn of a hidden danger. We conclude that Texaco did neither.
Hill strenuously argues that the damp and rusty walls of the tank were in an unsafe condition when Texaco turned the vessel over to Evans. It is true that the walls were rusty, but this condition is no occasion for holding that Texaco was negligent. Evans was hired as a specialist precisely to test the effect of rust on the thickness of the walls of the tank. Hill can *452 hardly argue that the ship was required to strip the tank walls of rust before turning the work over to Evans to test.
We reached a similar conclusion in
Hess v. Upper Mississippi Towing Corp.,
The rationale of
Hess
finds support in
West v. United States,
It appears manifestly unfair to apply the requirement of a safe place to work to the shipowner when he has no control over the ship or the repairs, and the work of repair in effect creates the danger which makes the place unsafe. The respondent, having hired Atlantic to perform the overhaul and reconditioning of the vessel — including the testing — was under no duty to protect petitioner from risks that were inherent in the carrying out of the contract.
Hill also urges that Texaco was negligent in turning over the tank to Evans immediately after purging the tank of ballast water. Undoubtedly, the damp walls of the tank exacerbated the slippery conditions of the stiffeners created by the loose rust. But that alone does not violate Texaco’s duty to exercise “ordinary care under the circumstances to have the ship and its equipment in such condition that an expert and experienced stevedore [or independent contractor supplying services] will be able by the exercise of reasonable care to carry on its cargo [or other] operations with reasonable safety to persons and property”
Scindia,
The tank, although wet, posed only a limited and accepted hazard to Hill until he elected to climb the rusted stiffeners without a safety line. Evans, as an expert in its field, could have brought safety lines with it or borrowed them from the ship. Had Evans done so, Hill could have completed the test with a reasonable degree of safety. Scindia teaches that the ship is entitled to assume that the independent contractor aboard ship will act reasonably with a view towards the safety of its employees. 101 5. Ct. at 1624. Were this not so, the LHWCA’s imposition of a negligence standard rather than a seaworthiness standard on the vessel’s conduct towards the harbor-workers would mean nothing. 6 We therefore conclude that there is no basis for *453 holding Texaco liable for Hill’s injuries aboard the TEXACO ILLINOIS. The judgment of the district court is REVERSED.
Notes
. The district court applied the land-based standards of conduct found in the Restatement (Second) of Torts, § 343 and § 343A. We approved this practice in
Gay v. Ocean Transport and Trading, Ltd.,
.
See Lemon v. Bank Lines, Ltd.,
.
See Pluyer v. Mitsui O.S.K. Lines, Inc.,
. In so holding, we do not resurrect the notion that a shipowner may defend against a longshoreman’s action by proving that the hazard that injured the longshoreman was “open and obvious.” We have read
Scindia
to repudiate this defense.
See Lemon v. Bank Lines, Ltd.,
. Before the enactment of the 1972 amendments to the LHWCA, longshoremen could recover against shipowners for the unseaworthiness of the vessel.
