Technip award pipeline contract by BG Trinidad and Tobago
Technip has been awarded a contract by BG Trinidad and Tobago for the flowlines(1) , risers(2), and umbilicals(3) for the North Coast Marine Area (NCMA) Development, offshore Trinidad.
The contract includes engineering, procurement, fabrication, installation, and pre-commissioning of the insulated riser, flowline and umbilical systems that will connect the Eastern Hibiscus and the Chaconia subsea wells to the Hibiscus Platform. The location is twenty-five miles northwest of Trinidad in NCMA Block 01 (East Hibiscus and Chaconia reservoirs) in 500 feet of water.
The work also includes engineering, fabrication and installation of two insulated steel flowlines with two flexible risers as well as the engineering, supply, installation, and pre-commissioning of two hydraulic control umbilicals. The detailed design engineering will be performed by Technip’s operations and engineering center in Houston.
The high-pressure flexible risers will be manufactured by Flexi France, one of the Group’s flexible pipe plants, located in Le Trait (France) while the hydraulic control umbilicals will be manufactured by Technip’s UK subsidiary, Duco, based in Newcastle. Fabrication of the rigid flowline will take place at Technip's spoolbase in Evanton (UK).
The offshore installation phase will use two vessels from Technip’s fleet: the Apache will lay the flowlines while the Wellservicer will install the flexible risers and umbilicals and offer diving and ROV(4) support for the completion of the work.
(1) Flowline: pipe laid on the seabed for the transportation of production or injection fluids. It is generally an infield line, linking a subsea structure (wellhead, template, manifold or riser base) to another structure or to a production facility. Its length ranges from a few hundred meters to several kilometers and its diameter from 4” to 19”.
(2) Flexible riser: a vertical flexible pipeline linking flowlines to surface structures.
(3) Umbilical: an assembly of hydraulic hoses which can also include electrical cables or optic fibers, used to control a subsea structure or ROV from a platform or a vessel.
(4) ROV (Remotely Operated Vehicle): an unmanned subsea vehicle remotely controlled from a vessel or an offshore platform. It is equipped with manipulator arms, which enable it to perform simple operations.
With a workforce of 21,000 people, Technip ranks among the top five corporations in the field of oil, gas and petrochemical engineering, construction and services. Headquartered in Paris, the Group is listed in New York and Paris. The Group’s main operations and engineering centers and business units are located in France, Italy, Germany, the UK, Norway, Finland, the Netherlands, the USA, Brazil, Abu-Dhabi, China, India, Malaysia and Australia. In support of its activities, the Group manufactures flexible pipes and umbilicals, and builds offshore platforms in its manufacturing plants and fabrication yards in France, Brazil, the UK, the USA, Finland and Angola, and has a fleet of specialized vessels for pipeline installation and subsea construction.
