HOUSTON, July 11 -- Statoil ASA has awarded a 440 million kroner contract to Norway's Aker Reinertsen—a joint venture of Aker Maritime ASA and Reinertsen AS—to integrate development of Tyrihans oil and gas field onto the Kristin and Aasgard B platforms in the Norwegian Sea.

Tyrihans gas will be processed on Kristin, and liquids on Aasgard B for transfer to Aasgard C storage and offloading (OGJ, Mar. 13, 2006, Newsletter).

The contractor will build and install a new manifold module for receiving the Tyrihans well stream on Kristin, a tie-in to existing systems, and a new outlet facility for gas injection on Aasgard B, including a gas meter. Gas from Aasgard B will be injected into the Tyrihans reservoir for pressure support.

In addition, the company will install equipment for direct electric heating of the tubing and electrical equipment for the newly awarded subsea water injection pumps (OGJ Online, June 16, 2006).

The work will begin immediately and complete by yearend 2008. Some steel fabrication will take place at Aker Reinertsen's workshop in Murmansk, Russia.

Tyrihans reserves are put at 182 million bbl of oil and condensate and 34.8 billion cu m of rich gas. Its development will cost about 14.5 billion kroner.

Production will begin in 2009 when spare capacity is available in Kristin's topside facilities.
