On 25 July 2002, due to a typhoon the Panamanian cargo vessel Co-op Venture, transporting a cargo of corn, ran aground in Shibushi Bay, 1.6 km off Osaki (Japan). During this accident, the ship sustained a split hull and has been stranded ever since.

The bunker fuel oil dispersion was promoted by rough conditions but a few hours after the grounding, containment devices were set up. Clean-up operations were rapidly planned and they took place on the Japanese coastline from 30 July to 1 August with 550 persons.

Pumping operations were performed effectively from 4 to 15 August and 70 % of the bunker fuel was recovered. Hydrogen sulphide emanations resulting from the corn decomposition caused the death of 4 people. Until 27 December, the remains of the Co-op Venture were salvaged with a crane ship.
