Construction under way on North Sea Gina Krog jacket

Offshore staff

VLISSINGEN, the Netherlands – Heerema Fabrication Group (HFG) has cut first steel for Statoil’s Gina Krog platform jacket in the central Norwegian North Sea.

This will be the largest launch-designed jacket HFG has built for Statoil. It will be around 142 m (466 ft) tall, with a footprint of 60 x 50 m (196 x 164 ft) and a top section of 42.5 x 26.25 m (139 x 86 ft). HFG Engineering is responsible for detailed design.

The 250-ton pre-drilling wellhead module, measuring 16 x 17 x 4 m (52 x 56 x 13 ft), will be integrated into the topsides cellar deck. This and the jacket are due to leave Vlissingen in April 2015.

Koos-Jan van Brouwershaven, CEO of HFG, said the company has invested in heavy-duty skid beams at the yard for this project.

Offshore installation is planned to start in summer 2015, with drilling through the jacket due to start soon afterward.

Gina Krog (ex-Dagny) is a gas, condensate and oil field, 30 km (18.6 mi) northwest of Sleipner. It is being developed with a fixed platform in 116 m (380 ft) of water and will be connected to the Sleipner facilities for gas export, with oil transported by tankers.
