Blue Marlin and her sister ship MV Black Marlin compose the Marlin class of semisubmersible heavy-lift ships operated by Dockwise Shipping of the Netherlands. Designed to transport very large, semisubmersible drilling rigs above the transport ship's deck, she is equipped with 38 cabins to accommodate 60 people, a workout room, sauna and swimming facilities, and a secure citadel for protection against pirate attacks.
History
Blue Marlin and her sister ship were owned by Offshore Heavy Transport of Oslo, Norway, from their construction, in April 2000 and November 1999, respectively, until 6 July 2001, when they were purchased by Dockwise. The U.S. Navy hired Blue Marlin from Offshore Heavy Transport to move the destroyer USS Cole (DDG-67) back to the United States after the warship was damaged by Al-Qaeda[2][3] suicide bombers while anchored in the port of Aden, Yemen. During the latter part of 2003, work done on Blue Marlin boosted her capacity and added two retractable propulsors to improve maneuverability. The ship re-entered service in January 2004.
