Q4000
''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. ''Q4000'' has a column-stabilized semisubmersible design that combines dynamically positioned station-keeping with a large deck space, significant deck load capacity and a high transit speed of 12 knots. The vessel provides a stable platform for a wide variety of tasks, including subsea completion, decommissioning and coiled tubing deployment, and she is specifically designed for oil well intervention and construction in depths of up to 3000 meters of water.

Helix Energy Solutions Group
Helix Energy Solutions Inc., known as Cal Dive International prior to 2006, is an American oil and gas services company headquartered in Houston, Texas. The company is a global provider of offshore services in well intervention and ROV operations of new and existing oil and gas fields. History Timeline 1980 – Oceaneering executives, Lad Handleman, John Swinden, Don Sites and Rick Foreman left the company and named their new company Cal Dive International. Oceaneering was formed in 1964 when Handelman merged his California oilfield diving company, Cal Dive, with Canadian-based Can-Dive and upon his departure Handleman reclaimed his original company name for the new venture. 1983 – Cal Dive Intl. was acquired by Diversified Energy International (DEI) whose financial backing allowed the company to expand with two converted diving vessels. 1985 –Handleman suffered a severe injury in a skiing accident and as a result was paralyzed from the waist down.

Blowout Preventer
A blowout preventer (BOP) (pronounced B-O-P, not "bop") is a specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the uncontrolled release of crude oil or natural gas from a well. They are usually installed in stacks of other valves. Blowout preventers were developed to cope with extreme erratic pressures and uncontrolled flow ( formation kick) emanating from a well reservoir during drilling. Kicks can lead to a potentially catastrophic event known as a blowout. In addition to controlling the downhole (occurring in the drilled hole) pressure and the flow of oil and gas, blowout preventers are intended to prevent tubing (e.g. drill pipe and well casing), tools and drilling fluid from being blown out of the wellbore (also known as bore hole, the hole leading to the reservoir) when a blowout threatens. Blowout preventers are critical to the safety of crew, rig (the equipment system used to drill a wellbore) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deepwater Horizon Oil Spill
The ''Deepwater Horizon'' oil spill (also referred to as the "BP oil spill") was an industrial disaster that began on 20 April 2010 off of the coast of the United States in the Gulf of Mexico on the BP-operated Macondo Prospect, considered to be the largest marine oil spill in the history of the petroleum industry and estimated to be 8 to 31 percent larger in volume than the previous largest, the Ixtoc I oil spill, also in the Gulf of Mexico. The United States federal government estimated the total discharge at . After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. Reports in early 2012 indicated that the well site was still leaking. The ''Deepwater Horizon'' oil spill is regarded as one of the largest environmental disasters in world history. A massive response ensued to protect beaches, wetlands and estuaries from the spreading oil utilizing skimmer ships, floating booms, controlled burns and of oil dispersant. Due to t ...

Top Kill
A top kill is a procedure used as a means of regaining control over an oil well that has been producing or is experiencing well control issues with crude oil or natural gas in the well. It is not a procedure where control has been lost over the well, like a blowout. The process involves pumping heavyweight drilling mud into the well. This procedure is expected to stop the flow of oil and gas from the well. A further step could be sealing the well completely, often with cement. In use The top kill procedure was used to plug flaming oil wells, blown up by retreating Iraqi forces, in 1991, during the Gulf War. This technique came to prominence during the 2010 Deepwater Horizon oil spill when it was used in an attempt to seal a seafloor oil well after the failure of the blowout preventer. However, it failed to block the flow of oil. References See also * Well kill * Blowout preventer A blowout preventer (BOP) (pronounced B-O-P, not "bop") is a specialized valve or similar ...

Remotely Operated Vehicle
A remotely operated underwater vehicle (technically ROUV or just ROV) is a tethered underwater mobile device, commonly called ''underwater robot''. Definition This meaning is different from remote control vehicles operating on land or in the air. ROVs are unoccupied, usually highly maneuverable, and operated by a crew either aboard a vessel/floating platform or on proximate land. They are common in deepwater industries such as offshore hydrocarbon extraction. They are linked to a host ship by a neutrally buoyant tether or, often when working in rough conditions or in deeper water, a load-carrying umbilical cable is used along with a tether management system (TMS). The TMS is either a garage-like device which contains the ROV during lowering through the splash zone or, on larger work-class ROVs, a separate assembly which sits on top of the ROV. The purpose of the TMS is to lengthen and shorten the tether so the effect of cable drag where there are underwater currents is minimize ...

Dynamic Positioning
Dynamic positioning (DP) is a computer-controlled system to automatically maintain a vessel's position and heading by using its own propellers and thrusters. Position reference sensors, combined with wind sensors, motion sensors and gyrocompasses, provide information to the computer pertaining to the vessel's position and the magnitude and direction of environmental forces affecting its position. Examples of vessel types that employ DP include ships and semi-submersible mobile offshore drilling units (MODU), oceanographic research vessels, cable layer ships and cruise ships. The computer program contains a mathematical model of the vessel that includes information pertaining to the wind and current drag of the vessel and the location of the thrusters. This knowledge, combined with the sensor information, allows the computer to calculate the required steering angle and thruster output for each thruster. This allows operations at sea where mooring or anchoring is not feasible du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
