MV Blue Marlin and her sister ship MV Black Marlin comprise the Marlin class of semi-submersible heavy-lift ship. They were owned by Offshore Heavy Transport of Oslo, Norway from their construction, in April 2000 and November 1999 respectively, until July 6, 2001, when they were purchased by Dockwise Shipping of the Netherlands. They were designed to transport very large semi-submersible drilling rigs, which can weigh 30,000 tons and have a center of gravity around 30 meters (100 feet) above the transport ship's deck. The Marlins are equipped with 38 cabins to accommodate 60 people, a workout room, sauna, and swimming facilities.

The U.S. Navy hired the Blue Marlin from Offshore Heavy Transport to move the destroyer USS Cole (DDG-67) back to the United States after the warship was crippled in Aden, Yemen, by suicide bombers.

During the latter part of 2003, work done on the Blue Marlin boosted its capacity and added two retractable propulsors to improve maneuverability. The ship re-entered service in January 2004.

Following these improvements, the Blue Marlin delivered the oil platform Thunder Horse, weighing 60,000 tons, to Corpus Christi, Texas for completion.

In July 2005 Blue Marlin moved the gas refinery Snøhvit from its construction site in Cádiz to Hammerfest, an 11 day trip. This transport was filmed for the TV show Kings of Construction on the Discovery Channel.

In November 2005, Blue Marlin left Corpus Christi, Texas, to move the massive Sea-based X-band Radar to Adak, Alaska, via the southern tip of South America and Pearl Harbor, Hawaii. It arrived at Pearl Harbor on January 9, 2006, having traveled 15,000 miles.

In January 2007, the Blue Marlin was employed to move two jack-up rigs, the Rowan Gorilla VI and the GlobalSantaFe Galaxy II, from Halifax Harbour to the North Sea.
