Total to install reelable electrically trace flowline at Islay

By OGJ editors
HOUSTON, Sept. 28
-- Total E&P UK Ltd. awarded Technip a €70 million engineering, procurement, construction, and installation contract that includes a 6-km reelable, electrically trace heated pipe-in-pipe flowline for the Islay gas field on UK Block 3/15 and Norway Blocks 29/6a and 29/6c.

Technip said the flowline will be the world’s first subsea implementation of this technology that aims to prevent flowlines from becoming blocked by the formation of hydrates or wax.

The Islay development, in 120 m of water, is a pilot project for the use of this technology, which is designed for both shallow and deep water, according to Technip.

The contract scope covers installation of the flowline, control umbilical, subsea structures, and seabed preparation, including detailed design, engineering and project management.

Technip’s operating center in Aberdeen will execute the contract, supported by the Evanton, Scotland spoolbase and the group's Genesis Oil and Gas Consultants and Duco units.

Scheduled offshore installation is set 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.

Total estimates Islay field, discovered in 2008, contains 17 million boe of gas and condensate. The company expects a peak gas production of 2.5 million cu m/day from the field, with first production starting in second-half 2011 (OGJ Online, July 15, 2010).

Total holds a 100% interest in Islay.
