Soft landing for Oseberg ěst modulesProjects and Operations // July 13, 2006
Three modules weighing 1,200 tonnes in total have been successfully lifted on board the Oseberg ěst platform in the North Sea.
The modules are part of an upgrade which will help in extracting 40 million new barrels of oil from the field.
It took seven hours for the lifting vessel Saipem 7000 to complete the lifting operation.
Saipem 7000 is the world's biggest semi-submersible lifting vessel.
"The lifting operation went exactly according to plan and the modules landed supersoftly on the platform," said Halldor Fottland, who was in charge of the operation.
The biggest of the modules is a 960-tonne mud-treatment module to be used during the coming drilling campaign on the field. The other modules are a turbine-driven power generator and a transformer.
During coming months the new systems will be connected and tested prior to the handover at the turn of the year.
The equipment now in place on Oseberg ěst will help in extracting 40 million new barrels of oil from the field. After modifications costing some NKr 800 million, the platform will be able to carry out drilling operations without using support vessels with mud-treatment equipment.
Inclusive of the drilling campaign that starts this winter, the upgrading of Oseberg ěst will cost around NKr 2.1 billion.
