Stolt Offshore has been awarded the flowlines and umbilical contract for the Vigdis Extension project. The total contract value is in the range of NOK 535 million, of which NOK 493 million is lump sum.

The Vigdis Extension project includes two new templates and two new satellite structures that will be tied back to the Snorre TLP via the existing Vigdis subsea infrastructure.

Stolt Offshore will provide engineering, procurement and installation of 23 kilometers of 6-inch and 12-inch water injection and production flowlines and umbilicals, including trenching, backfilling and gravel dumping. The installation of the two satellite structures is included into the scope.

Engineering work has commenced and offshore work is due to be carried out in the third quarter of 2003. The Vigdis Extension field is located in water depths ranging from 220 to 280 meters on block 34/7 in the Norwegian sector of the North Sea some 170 kms. north-west of Mongstad.

Hydro Technology's project manager, Jan Ingar Knudsen, is pleased with the award.

"Stolt Offshore submitted the most favourable tender and could meet our strict requirements with respect to the installation schedule next summer. This is of high importance for us, as the Vigdis Extension Project has an extremely tight schedule with production start set for December 15, 2003," he says.

The development project will be the responsibility of Norsk Hydro, HTP, throughout the project execution phase, even if Statoil takes over the operatorship of the Tampen area, including Vigdis, on Jan. 1, 2003, Knudsen explains. This ensures continuity within the project team and in all other respects.
