The Goliat platform will be partly electrified by a 106km subsea power cable, reducing the need for electricity produced by the platform’s gas turbines, lowering Goliat’s CO2 emissions up to 50 per cent.
According to ABB, the 123kV, 75MW high-voltage three-core polymeric (XLPE) insulated cable is the longest, most powerful cable ever delivered for an offshore application.
It will supply AC power from the mainland grid in Norway to Goliat, a floating oil and gas production, storage and offloading unit.
The cable integrates fibre optics to monitor temperature and provide general communication services, and includes a 1.5km dynamic section to accommodate the movement of the floating platform.
The project is scheduled for completion by the end of 2013, when Goliat is due to begin operations.
