Kongsberg Maritime, Saipem and Hereema Marine Contractors have secured contracts from Engie E&P Norge for modifications of Gjøa platform in the North Sea.

The contracts will see the firms involve in front-end engineering and design (FEED) studies for modifications at the platform.

The modifications are being carried out to allow the Skarfjell-licence (PL418), which is operated by Wintershall Norway, to link to the Engie E&P operated Gjøa platform via a subsea solution. 

Kongsberg Maritime will be responsible for FEED studies to modify and upgrade control and safety systems on Gjøa for the tie-in of Skarfjell. The work, which has already started, will be completed in August this year.

Saipem and Hereema Marine Contractors have received contracts for the FEED studies in relation to the offshore heavy lifting work.

The scope of the contract includes two separate and parallel studies to provide various options for safe and efficient lifting and installation of the Skarfjell-module on Gjøa. This work is also expected to complete in August this year.

Engie E&P Norge development and non operated ventures head Anne Botne said: "The contracts are central in preparing the Gjøa platform to be able to receive production from the Skarfjell-licence.

"The tie-in of Skarfjell production to Gjøa is in line with ENGIE E&P's strategy to make Gjøa a hub for future fields in the area and to extend the lifetime of the Gjøa platform."

According to the Norwegian Petroleum Directorate, Gjøa was the fifth most productive field on the Norwegian continental shelf last year.

Gjøa is a semi-submersible production unit that is operated with power from shore through a 100 km long submarine cable from Mongstad.

Engie E&P Norge is the operator of the PL153 Gjøa with 30% stake, while Petoro has 30% interest, Wintershall Norge holds 20% interest, Det Norske Shell owns 12% stake and DEA Norge owns 8% interest.
