HFG starts construction Gina Krog jacket

11 December 2013, Zwijndrecht

Heerema Fabrication Group’s Vlissingen yard in the Netherlands today celebrated the ceremonial first cut steel of the Gina Krog jacket, the largest launch jacket ever built at HFG for client Statoil Petroleum AS and destined for the Gina Krog field development in the central part of the North Sea.

Mr Svein Olav Høyland, Asset owner Representative of Statoil, performed the first cut of steel, which will be used to build the 17,000 tons Gina Krog jacket. The steel cutting took place at the yard of Heerema Fabrication Group (HFG) in Vlissingen (the Netherlands), where the jacket will be built. The Gina Krog jacket will be the largest launch jacket ever to be constructed at HFG’s Vlissingen fabrication facility. The jacket will be approximately 142 meters tall with a footprint of 60 x 50 meters and a top of 42.5 x 26.25 meters. The approximately 250 tons weighing pre-drilling wellhead module of 16 x 17 x 4 meters, will accommodate the phased development of the Gina Krog field and will be integrated into the topsides cellar deck.

The project award to HFG in February 2013 followed the successfully completed FEED study of the jacket by HFG’s engineering firm, HFG Engineering. Recently HFG Engineering completed the detailed design of the jacket main structure after which the construction of this record breaking 17,000 tons jacket started at Heerema Vlissingen. The delivery of the jacket and PDM (pre-drilling module) is scheduled for sail away in April 2015. 

“Today’s ceremony marks not only a major milestone in the start of the fabrication process, but also a new era in the design and fabrication capacities and capabilities at our yard in Vlissingen”, says Koos-Jan van Brouwershaven, CEO Heerema Fabrication Group. Koos-Jan continues: “Especially for this specific project, for our esteemed client Statoil, we have for instance invested in heavy duty skid beams on the yard which allows this challenging project to ensure an on-time, high quality and safe delivery”. 

Mr Svein Olav Høyland, Statoil’s Asset owner Representative, comments: “We are very pleased that we have met this important milestone and are now starting construction of the Gina Krog jacket. Gina Krog is one of Statoil’s mega projects and a significant contributor to Statoil’s long term production. The jacket being built at Heerema will be the first installation to be put on the Gina Krog field. The installation is planned summer 2015 and drilling through the jacket is planned to start shortly after.”

The Gina Krog (formerly known as Dagny) field development is a gas, condensate and oil field, located in the Norwegian central part of the North Sea, about 30 kilometres northwest of Sleipner. The Gina Krog field will be developed with a fixed platform in a water depth of 116 meters and will be tied into the Sleipner facilities for gas export with oil being transported by tankers.
