Bollinger Delivers 254 ft. Multi-Service Vessel

Bollinger Shipyards delivered a 254 ft. (77.4 m), 4,000-hp multi-service (MSV) for Oceaneering International, Houston, Texas. The vessel, which had its hull launching on Jan 1, was christened on May 19 by Cynthia Huber, wife of Dave Huber, director of deepwater projects, Mariner Energy.

Measuring 254 x 54 x 19 ft. (77.4 x 16.4 x 5.7 m). Ocean Intervention is an MSV designed for deepwater installation work. Two striking differences between this vessel and other offshore support vessels are its nearly flat bottom and two very large bowthrusters. The flat bottom was created to allow easier operation of remotely operated vehicles (ROV) and other equipment from the vessel's forward and aft 18 x 18 ft. moonpoools. Also implemented on the vessel are 6.5 ft. diameter bowthrusters — elements within the vessel's dynamic positioning system — that help to meet the ABS DPS-2 certification.

The diesel electric powered vessel develops a total of 5.470 EKW from two Caterpillar 3516B and two Caterpillar 3508 generators. Propulsion is provided by a pair of 2,000-hp-DC Aquamaster azimuthing thrusters (Zdrives) and two 1,000-hp Kamewa bowthrusters. The vessel's positioning is controlled by a fully redundant Kongsberg Simrad positioning system.

Able to carry 222,703 gallons of fuel; 3,000 gallons of lube oil and 74,371 gallons of potable water, the four deck vessel was constructed for the post delivery addition of a heliport, and is equipped with a 40-ton deck crane, 60-ton slewing stern A-frame and an anchor windlass.
