The 105.5km high-voltage alternating current (AC) three-core subsea power cable system features a 104km-long static cable section on the sea floor, and a 1.5km cable section.

Located in the production license 229 in the Barents Sea north of Russia and Norway, the Goliat oil field has the capacity to process up to 100,000 barrels of oil a day.

Goliat can also store nearly a million barrels of oil which will then be transferred to shore through tankers at a later stage.

The 75MW, 123kV capacity link will supply about 50% of the platform’s electricity needs from shore, reducing carbon dioxide emissions by half.

The cable section, which hangs in the water between the platform and the seabed, can withstand mechanical stress and fatigue caused by currents, waves and the platform’s vertical movement.

It will also facilitate increased energy supply to power additional fields in the future if required.

ABB Grid Systems business managing director Patrick Fragman said: "Reliable shore supplied power from the mainland grid will help to reduce the Goliat platform’s environmental impact, and ensure a safe and efficient operation."
