The 132 meter long, 4701 dwt tanker Volgoneft 263 sank while docked on the floating dock PD-154 at Ilyichevsk, Ukraine. The Vologneft 263 was being repaired when the dock lost stability and sank. The tanker’s hull had been cut for repairs which quickly allowed water ingress to sink it. The on board EPIRB sent out a distress signal that the vessel had sank. Pollution was released as 8,000 liters of diesel fuel and 1,300 liters of oil were on board the Vologneft. Booms were deployed to prevent the spread of pollution in the port. No reports of injuries.
