The Gjøa power‑from‑shore project is a dedicated high‑voltage alternating‑current (HVAC) submarine cable link that supplies electrical power from the Norwegian mainland to the Gjøa semi‑submersible production platform in the North Sea. Commissioned in 2010, the link was developed as a shore‑power solution to replace platform gas‑fired generation and thereby reduce...

2010Commercial Operations Full Power
The Gjøa power-from-shore electrification system, based on ABB’s high-voltage dynamic AC cable supplying alternating current from shore to the floating Gjøa production platform in the northern North Sea, entered operation in 2010. The dynamic 115 kV cable system has been successfully in service since then to deliver power from the mainland grid to the platform, providing one of the first high-voltage dynamic cable applications for offshore oil and gas electrification.
2010System Testing
ABB’s 115 kV dynamic AC subsea cable supplying power from shore to the Gjøa floating production platform in the northern North Sea underwent successful testing from 2010, demonstrating reliable operation of the dynamic export cable system for the Gjøa power-from-shore electrification link.
13 May 2009Procurement Other
Global Marine Systems entered into an agreement with ABB to complete subsea power cable installation works on three projects, including the StatoilHydro Gjøa power-from-shore link between the Mongstad power plant north of Bergen and the Gjøa floating production platform in the North Sea. Under this agreement, Global Marine Systems, replacing a previous installation provider, will use vessels such as CSV North Ocean 102 and CLV Team Oman along with associated personnel and equipment to finish the Gjøa cable installation campaign, which was estimated to be completed by Q2 2010 and is expected to cut CO2 emissions by about 250,000 tonnes per year from the platform.
