Heerema Ships Gina Krog Jacket

June 22, 2015

The Gina Krog jacket left the Heerema Vlissingen yard, the Dutch contractor has informed through its social media.

According to the company, the jacket set sail on Friday, June 19, for its final offshore destination in the Norwegian part of the North Sea.

The Gina Krog field development is a gas, condensate and oil field, located about 30 kilometers northwest of Sleipner.

The 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.

In December 2013, Heerema celebrated the ceremonial first cut steel of the Gina Krog jacket, for its client Statoil.

The project award to HFG in February 2013 followed the successfully completed FEED study of the jacket by HFG Engineering.

The following video shows a successful load out of the 17.000-ton jacket onto the barge, performed on March 28-29 at Vlissingen yard.

“The completion of this giant Gina Krog jacket and pre-drilling wellhead module highlights an important milestone at HFG’s Vlissingen yard”, says Koos-Jan van Brouwershaven, CEO Heerema Fabrication Group. “For this largest launch jacket ever built by HFG, we engineered and constructed a state of the art new flow measuring system which optimizes the upending capabilities of the jacket during installation. Due to its heavy weight we built skid beams on the Vlissingen yard, especially for this project, which enabled us to execute the load-out of the Gina Krog jacket from our yard onto the barge safe and with high quality. Successful delivery of this heavily built and immense launch jacket is the result of great teamwork and commitment to high performance and safety of Statoil & Partners as well as HFG.”
