STAVANGER, Norway – ENGIE E&P Norge has awarded front-end engineering and design (FEED) study contracts for modifications at the Gjøa semisubmersible platform in the Norwegian North Sea.
These are needed to enable the subsea tieback of the Wintershall-operatedSkarfjell field to the platform.
Kongsberg Maritime will undertake studies in connection with the modification and upgrading of control and safety systems on Gjøa for the tie-in. These should be completed in August.
Saipem and Heerema Marine Contractors will perform FEED related to offshore heavy-lifting work. The scope covers two separate and parallel studies that will clarify the different options for safe and efficient lifting and installation of the Skarfjell-module on Gjøa. These studies too are due to finish in August.
Anne Botne, head of Development and Non Operated Ventures at ENGIE E&P Norge, said: “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.”
The facility is operated with power from shore through a 100-km (62-mi) long submarine cable from Mongstad, western Norway.
Gjøa was the fifth most productive field on the Norwegian continental shelf in 2016, according to theNorwegian Petroleum Directorate.
Partners in the PL153 Gjøa are: ENGIE E&P Norge (operator and 30%), Petoro (30%), Wintershall Norge (20%), Det Norske Shell (12%), and DEA Norge (8%).
