Through a frame agreement in 2014, Kvaerner won the contract for the jackets for the riser platform (delivered in summer 2017); the drilling platform (completed in March); and the process platform, which yesterday sailed from the company’s yard in Verdal, western Norway for installation at the field complex.
Kvaerner said it had delivered all three substructures under a good co-operation with Equinor and subcontractors, on time and to the agreed quality.
The deliveries from Verdal comprise around 90% of the total substructure weight for the first- phase Sverdrup development - including the piles, Kvaerner will have fabricated close to 100,000 metric tons (110,231 tons) of steel, said EVP Structural Solutions, Sturla Magnus.
After securing a letter of intent for the riser platform and drilling platform jackets in June 2014, the contractor started design work immediately on the riser platform jacket.
It signed the following January, after a six-month pilot project had identified cost reduction and measures for improving competitiveness.
Kvaerner claims it can now deliver new jackets at a lower cost than in 2005.
