Bollinger Shipyards, Inc., Lockport, La., began the year 2000 on New Year's Day with the christening and launch of OCEAN INTERVENTION II, a 254 foot, 4,000 HP multi-service vessel (MSV) for Oceaneering International, Houston, Texas. Delivery is planned for the spring of 2000. Ocean Intervention II is a US flag, 254 ft. X 54 ft. X 19 ft. MSV designed for deepwater installation work.
Two obvious differences from other offshore support vessels are her nearly flat bottom and two very large bow thrusters compared to similar size vessels. The flat bottom was designed to permit easier operation of remotely operated vehicles (ROV) and other equipment from her forward and aft 18 ft. X 18 ft. moonpools. The 6.5 ft. diameter bow thrusters, elements in the vessel's dynamic positioning system, help to meet the American Bureau of Shipping (ABS) DPS-2 certification.The diesel-electric, SCR driven vessel will develop a total of 5,470 KW from two Caterpillar 3516B and two Caterpillar 3508 generators. Propulsion will be provided by two, 2,000 HP-DC AquaMaster azimuthing thrusters (Z-drives) and the two 1,000 HP-DC KaMeWa bow thrusters will aid maneuverability. One hundred sixteen linear foot port and starboard stabilizer fins and flume stabilization, or anti-roll tanks will aid in keeping the vessel stable. A fully redundant Kongsberg Simrad dynamic positioning system will control all the pertinent elements to keep OCEAN INTERVENTION II in position in operating sea conditions.
