Bisso Marine Co. has completed the salvage operation of a sunken drll rig at the Halter Gulf Repair Industrial Canal facility in New Orleans, La. The 145 x 97 x 22 ft. vessel sank 20 years ago, and had resisted many previous salvage attempts by other salvors. The rig was constructed with two 18 ft. diameter pontoons, which were connected by a substantial floor and interior bracing arrangement.
Bisso's salvage plan called for cutting the 860 ton wreck into three sections, in order to lift each section from multiple sling points, due to its deteriorated condition. Each section was placed onto a deck barge and safely transported from the derricks to a local scrap yard for offloading and disposal.
