The decision of an oil tanker company to change captains without a transfer period resulted in a $ 72.9 million marine accident, according to a National Transportation Safety Board (NTSB) marine accident report.

Shipping Accident File 21/24 details NTSB investigation into October 17, 2020 collision with oil and gas production platform SP-57B by the 159,500 dwt oil tanker flying the Maltese flag Atina near Pilottown, Louisiana.

According to the NTSB brief, the Atina was owned by Hanzhou 1 Ltd. and was operated by Besiktas Likid Tasimacilik Denizcilik Ticaret Anonim Sirketi, headquartered in Istanbul, Turkey. The platform owned and operated by Cox Operating LLC.

the Atina, with a crew of 21, was attempting to drop anchor in the anchorage of the Southwest Pass in the Gulf of Mexico when it struck the platform SP-57B. The four crew members and a platform technician were evacuated by helicopter to a nearby platform after activating the emergency stop device to close the wells of the SP-57B platform. No pollution or injuries were reported. The estimated damage to the platform ($ 72.3 million) and the vessel ($ 598,400) totaled $ 72.9 million.

In its report, the NTSB says Besiktas failed to comply with its own Safety Management System (SMS). The injured captain boarded the vessel en route to the anchorage, seeing only the departing captain on the deck of the tanker. The company placed the injured captain in the critical evolutions of the vessel, such as downstream navigation and night mooring, without any overlap with the departing captain.

The company’s SMS required a rotation of at least one day between senior managers aboard a company vessel if the oncoming senior manager was working for the company, and seven days if the senior manager was new to the business.


According to the report, the captain of the accident told investigators he wanted to anchor the ship as soon as possible because he was tired. The captain of the accident traveled from Turkey to join the ship and told investigators he had not slept for more than 50 hours during the trip.

The location he chose did not follow the anchor location of the passage plane. According to Atina ‘According to the passage plan, the tanker’s planned anchorage was approximately 3.2 miles northeast of SP-57B. The actual anchor location was approximately 0.7 mile from the SP-57B platform.

Investigators determined that the probable cause of the tanker’s contact with the production platform was Atinathe captain’s operating company did not allow sufficient time for the captain’s rotation, resulting in acute captain fatigue and situational awareness when attempting to evolve the anchor from night.

“Vessel operating companies should ensure that joining crew members / personnel have the opportunity to obtain sufficient transfer period and adequate rest before taking on critical tasks on board, such as navigation, which could have an impact on the safety of the crew, property and the environment, “the report said. In this case,” an overlap would have allowed the incoming master to rest and receive peer transfer information ”.
