Full service offshore and subsea infrastructure services contractor, BISSO MARINE, has successfully completed a two month saturation diving campaign in the Gulf of Mexico. The company performed a variety of subsea infrastructure services, including several subsea abandonments in water depths ranging from 91 - 220 m.
Other work included reverse 'J' recovery of several miles of unpiggable 6 in. pipeline from 122 m of water. The pipeline was lifted vertically through one of the moonpools on the BISSO SUBSEA VISION. It was vented, saw cut and scrapped within an enclosed decommissioning system that is designed to capture the contents of the pipeline.
The BISSO SUBSEA VISION recently completed the lay and burial of several miles of bundled pipeline in the US Gulf of Mexico in less than 60.9 m of water. While the BISSO SUBSEA VISION has moved on to its next decommissioning assignment, the bundled pipeline tie-ins will be performed using the company’s four point DSV JOSEPH BISSO.
The fully classed 12 man saturation system on the BISSO SUBSEA VISION has a 3 man bell deployed through a moonpool and a side launched hyperbaric rescue chamber (HRC). It is configured with two pedestal cranes. The main crane has a 300 t capacity and the auxiliary crane has a 60 t capacity.
