The owners 1 of a sunken barge appeal from a judgment holding them responsible for removing the wreck under the Rivers and Harbors Act of 1899, ch. 425, 30 Stat. 1152 (codified as amended at 33 U.S.C. §§ 401 et seq.). We affirm the judgment of the district court.
I.
The M/V CLARKE BERRY left Pensacola, Florida for Port Sulphur, Louisiana on the morning of March 23, 1979. It was pushing a single barge, the CBC-21, loaded with about 2,500 tons of molten sulphur. At about eight o’clock that evening, tow boat and barge were heading due west across lower Mobile Bay in fair weather. About two-thirds of the way across the Bay, the barge suddenly began to buckle amidship. The captain continued pushing the barge westward to clear the main north-south ship channel. Barge CBC-21 sank about 500 yards west of the north-south channel in twelve feet of water, with its mid-section resting on the bottom and its bow and stern out of the water. Investigations by the Navy, the Coast Guard, and the defendants failed to determine conclusively the cause of the buckling.
The defendants kept the wreck marked and lighted for four days and then abandoned it. The Coast Guard marked the wreck with a temporary buoy, and later erected a permanent marker with a flashing light. 2
Barge CBC-21, built in 1960, was a steel-welded tank barge 280 feet long, 50 feet wide, and 1272 feet deep. About two weeks before it sank, the Avondale Shipyards repaired some cracks in the bow and stern sections of the barge. The district court found that the defendants failed to comply with a regulation requiring notification (which may be informal) of the repairs to the Coast Guard and Coast Guard inspection of the completed repairs.
The United States sued the defendants to recover the costs of marking the wreck. The government also sought an injunction requiring the owners to remove the wreck and a declaration that the defendants are liable for the costs of removal. The district court found the defendants liable under § 15.33 U.S.C. § 409, for negligently causing the barge to sink, and granted the injunction.

Our Court has held that a sunken vessel is an “obstruction” within the meaning of § 10 of the Act.
United States v. Raven,
5 Cir.1974,
Our Court has not decided whether § 10 imposes strict liability on those who create obstructions to the navigable capacity of United States waters. The language of the statute suggests liability without fault. In
University of Texas Medical Branch at Galveston v. United States, 5
Cir.1977,
We find it unnecessary to decide the applicability of § 10 to this case, because we agree with the district court’s finding of liability under § 15. We are confirmed in this course by our recognition that the question raised by applying § 10 to wrecks are serious. First, a strict liability rule
III.
The district judge held the defendants to have been negligent and therefore liable under § 15 of the Rivers and Harbors Act, 33 U.S.C. § 409. Section 15, part of the Wreck Act, makes shipowners liable for “voluntarily or carelessly” causing their vessels to sink in navigable channels.

“Carelessness” under § 15 is equivalent to negligence.
Nunley v. M/V Dauntless Colocotronis,
5 Cir.1984,
Section 15 requires all owners, whether negligent or not, to warn other vessels by marking the wreck. Innocent shipowners may then abandon the wreck. If they do so, they have no obligation under § 15 to remove the wreck or to continue marking it as a hazard to navigation.

Agri-Trans Corp. v. Gladders Barge Line, Inc.,

The crucial issue under § 15, therefore, is whether the vessel owner’s negligence caused the vessel to sink. The district court found that the defendants were negligent on the basis of the doctrine of

We have held that § 15 requires removal only if the wreck is an obstacle to navigation.

When a vessel sinks in calm weather, absent evidence that the crew was negligent, the vessel may be presumed to have been unseaworthy.

See Commercial Molasses Corp. v. New York Tank Barge Corp.,
1941,
Unseaworthiness alone does not necessarily imply negligence.
11
The Supreme Court has held that liability for unseaworthiness “is essentially a species of liability without fault.”
Seas Shipping Co. v. Sieracki,
1946,
The district court did not simply equate negligence and unseaworthiness. Rather, the court concluded that a particular set of facts concededly supporting an inference of unseaworthiness will also support an inference of negligence. The Supreme Court has said that the inference of unseaworthiness is merely “a particular application of the doctrine of
res ipsa loquitur,
which similarly is an aid to the plaintiff in sustaining the burden of proving breach of the duty of care ...”.
Commercial Molasses Corp.,

Brown & Root Marine Operators, Inc. v. Zapata Off-Shore Co.,
5 Cir. 1967,
C.
Under the Rule of The
Pennsylvania,
a party who fails to observe a safety regulation has the burden of showing “not merely that [its] fault might not have been one of the causes [of the loss], or that it probably was not, but that it could not have been”.
About two weeks before it sank, Barge CBC-21 and another barge owned by the defendants, the CBC-32, underwent repairs and maintenance at the Avondale Shipyards. The repairs to Barge CBC-21 were made to the bow and stern sections. Federal regulations require Coast Guard supervision and inspection of such repairs.
13
The district court found that the defendants failed to have the work inspected, thus
A Coast Guard witness testified that Barge CBC-21 should have been inspected twice, once before the work began and again after the work was finished. Hence not one but two log entries are missing. Moreover, if the work had been inspected, the inspector should have filed a report with the Coast Guard Marine Inspection Office in New Orleans in addition to making the entries in the logbook. No report was found. Finally, a Coast Guard witness testified that the repairs did not meet Coast Guard specifications, and so would not have passed inspection. In the light of this evidence, we conclude that the trial judge could properly find that the repairs were not inspected as required by Coast Guard regulations.
We further conclude that the defendants did not carry the burden of showing that the violation could not have contributed to the loss. A naval architect testified that the cracks in the bow and stern were telltale signs that the hull had been strained amidship. The witness speculated that the barge may have been in an unreported collision. True, there was conflicting testimony that unloaded barges, riding high in the water, often run up on other barges or on docks, causing fractures in their plating. In either event, as the bow or stern rises out of the water, additional strain is placed on the mid-section of the hull. The Coast Guard inspector therefore might have decided to search for damage amidship on the basis of the fractures in the bow and stern. A Coast Guard witness testified that the inspector’s task is to determine whether the vessel needs repairs in addition to those ordered by the owners. The witness described a procedure called “stepladdering”, in which the inspector considers whether the damage already found could have been caused at the same time as other damage, and then looks for additional damage. We are persuaded that the Coast Guard inspector might have performed such an investigation.
A structural infirmity amidship is consistent with the facts relating to the barge’s sinking and would have been detected by an inspection. The naval architect testified that if Barge CBC-21 had been structurally sound, it would not have buckled even if the sulphur tanks ruptured and leaked a large amount of sulphur amid-ship. The architect’s testimony suggests that a structural defect amidship was at least a contributing cause of the sinking.
Considering the known facts and the fact that the mishap is of a type that ordinarily does not occur in the absence of negligence, as the district court found, the district court properly applied the doctrine of res ipsa loquitur and the Pennsylvania Rule which, at least in this circuit, has long been followed.
The judgment of the District Court is AFFIRMED.
Notes
. Barge CBC-21 was owned by Nassau Marine Corporation, a wholly-owned subsidiary of Canal Barge Company. The M/V CLARKE BERRY is owned by Webster Marine Corporation, another wholly-owned subsidiary of Canal. Both Barge CBC-21 and the CLARKE BERRY were operated by Central Marine Service under a charter party with Canal. Canal and Central Marine have the same owners, officers, and directors.
. The appellants satisfactorily removed the barge from Mobile Bay in December 1984.
. Section 10 reads:
The creation of any obstruction not affirmatively authorized by Congress, to the navigable capacity of any of the waters of the United States is prohibited; and it shall not be lawful to build or commence the building of any wharf, pier, dolphin, boom, weir, breakwater, bulkhead, jetty, or other structures in any port, roadstead, haven, harbor, canal, navigable river, or other water of the United States, outside established harbor lines, or where no harbor lines have been established, except on plans recommended by the Chief of Engineers and authorized by the Secretary of the Army; and it shall not be lawful to excavate or fill, or in any manner to alter or modify the course, location, condition, or capacity of, any port, roadstead, haven, harbor, canal, lake, harbor of refuge, or inclosure within the limits of any breakwater, or of the channel of any navigable water of the United States, unless the work has been recommended by the Chief of Engineers and authorized by the Secretary of the Army prior to beginning the same.

. The
Cargill
case appears to have been brought because the government found the statutory remedies for violations of § 15 inadequate. Sections 19 and 20 provide only for raising sunken vessels and selling them. Section 16 makes violations of § 15 punishable by a fine of $2,500 and a year’s imprisonment. Section 12 in contrast authorizes injunctive relief for violations of § 10. The
Republic Steel
case extended the availability of injunctions under § 12 to obstructions other than "structures”.

. In that footnote the Court suggests that to hold shipowners strictly liable under § 10 for removing wrecks when only negligent shipowners are liable under § 15 would be "anomalous”.
. The Baycon opinion, however, holds that the government must prove that the defendant performed some act likely to cause the harm before the court will impose criminal liability under § 12 of the Act. Id. at 1507. The opinion expressly restricts the holding to criminal liability, however. Id.
. The defendants suggest a fourth difficulty which need not detain us. They argue that the Louisiana district court lacked jurisdiction over the case, since the wreck lies off the coast of Alabama. Republic Steel and Wyandotte rights of action in personam under §§ 10 and 15, respectively. We find the defendants' contention that in personam actions must be brigaded with an in rem claim without merit.
. Section 15 reads in part:
It shall not be lawful to ... voluntarily or carelessly sink, or permit or cause to be sunk, vessels or other craft in navigable channels____ And whenever a vessel, raft, or other craft is wrecked and sunk in a navigable channel, accidentally or otherwise, it shall be the duty of the owner of such sunken craft to immediately mark it with a buoy or beacon during the day and a lighted lantern at night, and to maintain such marks until the sunken craft is removed or abandoned, and the negleet or failure of the said owner to do so shall be unlawful; and it shall be the duty of the owner of such sunken craft to commence the immediate removal of the same, and prosecute such removal diligently, and failure to do so shall be considered as an abandonment of such craft, and subject the same to removal by the United States as provided for in sections 411 to 416, 418, and 502 of this title.
