Technip to install world's first electrically trace heated pipe-in-pipe at Total's Islay

Source: Technip

French engineering and oilfield services firm Technip (OP:TKPPY) has been awarded a US $94 million (€70 million) subsea contract by Total (NYSE:TOT) for the Islay gas field. According to the contract, Technip will deliver full engineering, procurement, construction and installation (EPCI) of subsea flowlines and control umbilical on the Islay gas field

The contract will involve the world’s first subsea implementation of Technip’s reelable, electrically trace heated pipe-in-pipe (ETH-PIP) technology. ETH-PIP aims to enhance production operability of subsea pipelines that are liable to become blocked by the formation of hydrates or wax. 

Successful application of this technology will reduce capital and operating costs for fields with challenging flow assurance conditions. The Islay project is a pilot project for the use of this innovative pipeline technology, which is designed for both shallow and deepwater environments. 

The full workscope covers installation of a 6-kilometer ETH-PIP, control umbilical, subsea structures and seabed preparation, including detailed design, engineering and project management. 

Technip’s operating center in Aberdeen, Scotland will execute the contract, supported by the Evanton, Scotland spoolbase and Group entities Genesis Oil and Gas Consultants and Duco. Offshore installation is scheduled for mid-2011 and will be carried out by vessels from the Technip fleet, including the new pipelay vessel, Apache II, and diving support vessels Skandi Arctic and Skandi Achiever. 

Operated by Total, the Islay field is located in the UK North Sea, 440 kilometers northeast of Aberdeen, in 120 meters of water. The field is being developed as a subsea tieback to the Alwyn facility nearby, and first production is planned for the second half of 2011.
