Repair of Mariner Energy's Deepwater High Pressure Flowlines

摘要

As with most complex subsea intervention jobs, the Pluto and Dulcimer repairs experienced minor difficulties that required adjustments to planned procedures. In some instances, these adjustments could be made without difficulty by the ROV. In others, however, the involvement of the WASP, with its direct human presence, all-around visibility, delicate touch and dexterity, greatly facilitated the required adjustment or adaptation. The WASP and ROV are a powerful subsea intervention spread for performing complex workscopes in water depths to 2,300 feet. The combined capabilities of the two systems reduce the offshore time required to complete a job, permitting savings on vessel costs. Below 2,300 ft, the basic repair procedures can be adapted for the ROV alone, with only small modifications to the tooling and equipment.
