HOUSTON, Mar. 24 -- Corus Tubes was let a contract for more than 150,000 tonnes (roughly 500 km) of 18-in. and 30-in. OD pipe for use West of Shetland in development of Total SA’s Laggan-Tormore offshore gas field. Corus will manufacture the pipe at its Hartlepool facility through 2010 and into 2011.

The £2.5 billion development lies in 600 m of water on Blocks 206/1a, 205/4b, and 205/5a about 140 km off the Shetland Islands. Total estimates the fields contain 230 million boe of reserves and will have a 500 MMscfd peak gas production rate or a 93,000 boe/d peak rate when condensates are included.

The company plans to start work almost immediately on the offshore gas infrastructure and on a new gas processing plant at Sullom Voe on Shetland. It expects first gas production in 2014 (OGJ Online, Mar. 17, 2010).

The overall development concept consists of a long distance tie-back of subsea wells connected to the plant at Sullom Voe, with further export of the processed gas to the UK Frigg pipeline system in the North Sea.

The subsea production system offshore will consist of two identical six-slot template-manifolds, with up to eight development wells required to produce the expected reserves. The commingled, multiphase fluid stream will be transported to shore via two 18-in. OD production flowlines.

Dong Energy (20%) is Total’s partner in developing Laggan-Tormore.

Corus Tubes, Europe's second largest steel producer, is a subsidiary of the Tata Steel Group.
