Anasuria production vessel is destined for U.K. North Sea service.
The Anasuria floating production, storage, and offloading vessel built for Shell U.K. Exploration & Production has arrived at Tyneside, U.K., for fitting of topsides processing plant and a mooring turret.
The 129,550 dwt vessel will be part of a 500 million ($750 million) development project for Shell-Esso's Guillemot, Teal, and South Teal oil discoveries in U.K. North Sea Blocks 21/25 and 21/30.
Meantime, Norske Shell AS began gas production from Troll field in the Norwegian North Sea to allow commissioning of the platform and onshore processing plant in readiness for start of commercial deliveries Oct. 1.
Anasuria FPSO
Shell's Anasuria is moored alongside the AMEC Process & Energy Ltd. yard at Wallsend for completion. It arrived after a 75 day tow from the Mitsubishi Heavy Industries construction yard at Nagasaki, where it was built.
The ship will be able to process 55,000 b/d of oil, store 850,000 bbl of oil, inject 85,000 b/d of water, and export 30 MMcfd of gas (OGJ, Mar. 6, 1995, p. 33). Production is expected to begin by yearend.
Shell Expro, the operating joint venture of Shell U.K. Ltd. and Esso Exploration & Production U.K. Ltd., began development drilling in November 1995. Eight producing wells and four water injection wells are to be complete in 1998.
Troll field's concrete gravity base structure is the world's largest gas production platform. Its capacity is 100 million cu m/day of gas, which a Shell spokesman said will double Norway's gas production.
First gas is being used for commissioning offshore equipment. The processing plant at Kollsnes on the Norwegian coast is expected to receive its first deliveries this month.
The platform was installed in May 1995, and Shell soon afterward began its program of development drilling.
Troll gas reserves are estimated at 45 tcf (OGJ, Nov. 27, 1995, p. 25).
