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.
An oil platform is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed. Many oil platforms will also have facilities to accommodate the workers, although it is also common to have a separate accommodation platform linked by bridge to the production platform. Most commonly, oil platforms engage in activities on the continental shelf, though they can also be used in lakes, inshore waters, and inland seas. Depending on the circumstances, the platform may be fixed to the ocean floor, consist of an artificial island, or float. In some arrangements the main facility may have storage facilities for the processed oil. Remote subsea wells may also be connected to a platform by flow lines and by umbilical connections. These sub-sea facilities may include one or more subsea wells or manifold centres for multiple wells.
Offshore construction is the installation of structures and facilities in a marine environment, usually for the production and transmission of electricity, oil, gas and other resources. It is also called maritime engineering.
A semi-submersible platform is a specialised marine vessel used in offshore roles including as offshore drilling rigs, safety vessels, oil production platforms, and heavy lift cranes. They have good ship stability and seakeeping, better than drillships.
Mighty Servant 2 was a 29,000-ton semi-submersible, heavy-lift ship operated by Dockwise. The ship drew worldwide attention in 1988 for transporting the mine-damaged USS Samuel B. Roberts from Dubai to Newport, Rhode Island.
The American Bureau of Shipping (ABS) is an American maritime classification society established in 1862. Its stated mission to promote the security of life, property, and the natural environment, primarily through the development and verification of standards for the design, construction and operational maintenance of marine and offshore assets.
A crane vessel, crane ship, crane barge, or floating crane is a ship with a crane specialized in lifting heavy loads, typically exceeding 1,500 t for modern ships. The largest crane vessels are used for offshore construction.
Offshore drilling is a mechanical process where a wellbore is drilled below the seabed. It is typically carried out in order to explore for and subsequently extract petroleum that lies in rock formations beneath the seabed. Most commonly, the term is used to describe drilling activities on the continental shelf, though the term can also be applied to drilling in lakes, inshore waters and inland seas.
Mighty Servant 3 is a 27,000-ton semi-submersible heavy lift ship. Its deck is 40 by 140 m. The vessel was built in 1984 by Oshima Shipbuilding Co. Ltd. in Ōshima, Japan, for Dutch shipping firm Wijsmuller Transport, which merged in 1993 with Dock Express Shipping to become Breda-based offshore heavy lifting group Dockwise Shipping B.V.
A jackup rig or a self-elevating unit is a type of mobile platform that consists of a buoyant hull fitted with a number of movable legs, capable of raising its hull over the surface of the sea. The buoyant hull enables transportation of the unit and all attached machinery to a desired location. Once on location the hull is raised to the required elevation above the sea surface supported by the sea bed. The legs of such units may be designed to penetrate the sea bed, may be fitted with enlarged sections or footings, or may be attached to a bottom mat. Generally jackup rigs are not self-propelled and rely on tugs or heavy lift ships for transportation.
A heavy-lift ship is a vessel designed to move very large loads that cannot be handled by normal ships. They are of two types:
Dockwise was a Netherlands-based holding company in the marine transport industry. It was acquired by Boskalis in 2013 and was merged into the Boskalis brand name in 2018.
Q4000 is a multi-purpose oil field construction and intervention vessel ordered in 1999 by Cal Dive International, and was built at the Keppel AmFELS shipyard in Brownsville, Texas for $180 million. She was delivered in 2002 and operates under the flag of the United States. She is operated by Helix Energy Solutions Group. The original Q4000 concept was conceived and is owned by SPD/McClure. The design was later modified by Bennett Offshore, which was selected to develop both the basic and detailed design.
Thunder HorsePDQ is a BP plc and ExxonMobil joint venture semi-submersible oil platform on location over the Mississippi Canyon Thunder Horse oil field, in deepwater Gulf of Mexico, 150 miles (240 km) southeast of New Orleans, moored in waters of 1,840 metres (6,040 ft). The "PDQ" identifies the platform as being a Production and oil Drilling facility with crew Quarters.
The Mafuta is a diamond-mining ship owned and operated by De Beers in the western coast of South Africa. Built in 1983 as Dock Express 20 for Dock Express Shipping, the semisubmersible, multirole, heavy-lift vessel was converted to the world's largest cable layer in 1993. In 2005, she was purchased by De Beers, and converted to a subsea diamond-mining ship by A&P Tyne over the course of 11 months. The ship's new name, Peace in Africa, may have implied that it was providing an alternative to blood diamonds. In 2013, still under ownership of De Beers Marine Namibia, the vessel was renamed to MV Mafuta.
Integrated Software Dependent Systems (ISDS) is an offshore standard (DNV-OS-D203) and recommended practice guideline (DNV-RP-D201) covering systems and software verifications and classification of any integrated system that utilizes extensive software control. The ISDS Recommended Practice (DNV-RP-D201) was launched in 2008 by Det Norske Veritas (DNV), the Norwegian classification society. DNV Offshore Standard OS-D203 launched in April 2010.
BOKA Vanguard is a semisubmersible heavy-lift ship owned and operated by Dockwise B.V. Dockwise Vanguard is the largest vessel of her type ever built, and is able to carry cargoes up to 110,000 tonnes. Dockwise Vanguard was designed to move offshore oil and gas facilities, but can also carry other ships and act as an offshore dry-dock facility.
Semi-submersible may refer to a self-propelled vessel, such as:
Ocean development refers to the establishing of human activities at sea and use of the ocean, as well as its governance.
Bethlehem Beaumont Shipyard was a shipyard in Beaumont, Texas that opened in 1948. The yard is located on an island in the Neches River and upstream of the Sabine Pass that grants access to the Gulf of Mexico. The deep-water port shipyard was founded in 1917 as the Beaumont Shipbuilding & Dry Dock Company. Beaumont Shipbuilding & Dry Dock Company started as a World War I Emergency Shipbuilding Program yard.
