Letters of intent totalling just over NOK 430 million for Sleipner West’s Alpha North satellite development in the North Sea have been awarded by Statoil on behalf of the licensees.
Placed with Allseas Marine Contractors, Sumitomo Corporation, European Marine Contractors and Subsea7, these assignments cover line pipe deliveries, pipelaying and marine operations.
Allseas will trench and lay a flowline about 18 kilometres long to tie Alpha North back to the Sleipner T platform on the Sleipner East field. This job is worth NOK 226 million.
Under a contract valued at NOK 106 million, Sumitomo – represented by Sumitomo Metals – will deliver line pipe to the project.
European Marine Contractors will install the subsea template and manifold on Alpha North, and to trench and lay the umbilical linking these facilities with the A platform on Sleipner East.
This contract is worth some NOK 50 million, while Subsea7’s job is just over this amount. It covers installing spool pieces in the flowline and tie-in of flowline and umbilical to the satellite.
“These awards mean that the Alpha North development has really got going,” says Thor Christian Andvik, procurement manager for the project.
He reports that the template is due to be installed in May, with the manifold following next September.
The flowline and umbilical will be delivered in a year’s time, with laying and other marine operations scheduled for April-July 2004.
Statoil has already given Aker Kværner the contract for modifications on and satellite tie-in to the Sleipner T and A platforms.
Transocean has also been contracted to drill and complete production wells for Alpha North, which is due to begin delivering condensate and gas on 1 October 2004.
