Bisso Marine Delivers GoM Diving Projects

bisso-marine-delivers-gom-diving-projects-2Bisso Marine has completed a two‐month saturation diving campaign in the Gulf of Mexico.

Using its 126.4-meter construction barge, Bisso Subsea Vision, configured with a 12‐man ABS-classed 300m saturation system, the company said it performed a variety of subsea infrastructure services including several subsea abandonments in water depths ranging from 91 meters to 220 meters.

Other scopes of work included a Reverse ‘J’ recovery of several kilometers of unpiggable 6 inch pipeline from 122 meters of water. The 6 inch pipeline was lifted vertically through one of the moonpools on Bisso Subsea Vision. The pipeline was vented, saw cut and scrapped within an enclosed decommissioning system designed to capture the contents of the pipeline.

The same vessel also recently wrapped up the lay and burial of several kilometers of bundled pipeline in the Gulf of Mexico in less than 61 meters of water. While the vessel moved on to its next decommissioning job, the bundled pipeline tie‐ins will be executed using the company’s four-point DSV Jospeh Bisso.
