Statoil and its partners plan to invest 11 billion kroner in two new compressors on Troll A platform in the North Sea to enable natural gas production with reduced wellhead pressure and to extend the life of the field.
The new compressors are expected to extend gas production from the field until 2063.
New compressors also pave the way for the tie-in of gas from Troll West once oil production ends. The two compressors are scheduled to come on stream in 2015, enabling Troll A to produce 120 million cu m/day until 2018 and 30 billion cu m/year until 2024.
Hans Jakob Hegge, Statoil senior vice-president for operations North Sea east, said Troll A accounts for one third of all gas capacity on the Norwegian Continental Shelf.
Statoil awarded Aibel a 2.7 billion kroner contract for modules and modifications for two new precompressors. Aibel will provide engineering, procurement, onshore construction, and integrated offshore construction and completion work to upgrade Troll A’s precompression capacity.
The work was scheduled to start immediately, with offshore installation starting in 2012.
