OSLO -- StatoilHydro has transported the subsea raw seawater injection (SRSWI) pumps for the Tyrihans field from its Tranby facility to Horten, where the pumps will undergo installation testing. Once installed, the pumps are expected to increase oil production from the Tyrihans field by 10%, the company says.
The pumps, which use Aker Solutions' LiquidBooster technology, will be installed in 270 m (886 ft) water depth approximately 31 km (19 mi) from the Kristin platform.
Aker Solutions injection system consists of three subsea pump modules, including one spare pump module, complete power system, structure and manifold, and a comprehensive condition monitoring system.
The pumps will suck in 14,000 cu m of untreated seawater each day, and inject it into the reservoir. The pumps drive the water into the ground between the oil reservoirs Tyrihans North and South. It is expected that the pumps alone will help increase production by 19 MMbbl of oil during the field's lifetime, the company says.
