Statoil has signed a letter of intent with Aker Kvaerner to deliver a subsea seawater injection system for the Tyrihans project in the Norwegian Sea. The new generation pumps are expected to increase oil production from the Tyrihans field by 10%. The subsea pumps will be the world's largest and installed at longest stepout. Aker Kvaerner's contract value will be approximately NOK 200 million.
Aker Kvaerner Subsea will supply two subsea injection pumps to be installed more than 40 kilometres from the Kristin platform where the oil and gas will be processed. The pumps will feature Aker Kvaerner's own LiquidBoosterTM technology and will inject raw sea water for pressure support and stabilisation of the oil zone.
"Aker Kvaerner has developed a robust technology for the subsea raw seawater injection pump system for Tyrihans. The high capacity of Aker Kvaerner's boosting system combined with its robustness and simplicity in design has been a decisive factor for Statoil in this contract award," says Tyrihans technical responsible for pump system Torstein Austvik.
Aker Kvaerner will manufacture the pump system at its facility in Tranby in Norway for delivery in the third quarter of 2008. Production on Tyrihans, one of the largest planned projects on the Norwegian continental shelf, is due to begin mid-2009.
"This is a breakthrough for another of our boosting technologies already well proven onshore. It is the latest in a string of recent projects that will benefit from this technology," says Raymond Carlsen, executive vice president Aker Kvaerner Subsea.
Statoil has a 46.8 per cent interest in the Tyrihans field, while its partners are Total with 26.51 per cent, Hydro with 12 per cent, Eni with 7.9 per cent and ExxonMobil with 6.75 per cent.
