A jack-up rig in the Southern North Sea, was making preparations to abandon the Esmond 43/13a-5 well. During this operation the 30”casing pipe was cut to retrieve it. While pulling the 30”casing something went wrong and the casing and Texas Deck (auxiliary deck suspended below the rig floor) were lost and sank to the bottom of the sea.

Last July Mammoet Salvage was awarded the salvage contract regarding the sunken 730 mT supply vessel "TSC Supreme". This vessel sunk after she collided with a gas production platform.
Location, Bul Hanine Field, Persian Gulf.
