LAYING OF JOHAN SVERDRUP POWER CABLE STARTED

May 15, 2018

The laying of the cable supplying Johan Sverdrup with power from shore started last week. This helps make the North Sea giant one of the oil and gas fields with the lowest CO2 emissions worldwide.
On Wednesday last week the cable-laying vessel NKT Victoria began laying the cables that will supply the Johan Sverdrup field with power from shore.
The starting point was the Johan Sverdrup converter station at Haugsneset near Karsto, and by the end of May the vessel will have laid nearly 200 kilometres of power cables out to the field in the North Sea.
Bundled with the power cables, a fibre-optic cable will once installed ensure good communication and enable monitoring and, when required, remote control of parts of the Johan Sverdrup field’s operations from shore.
“We are now laying the very lifeline of the Johan Sverdrup field, which will supply the field with power from shore for more than 50 years” says Trond Bokn, senior vice president for Johan Sverdrup.
The power cables will help make Johan Sverdrup one of the most carbon-efficient oil and gas fields in the world. Estimated at just 0.5 kg of CO2 per barrel, the emissions from Johan Sverdrup are about 20 times lower than the average on the Norwegian continental shelf, and 30 times lower than the international average. This makes Johan Sverdrup a key project to help deliver on Statoil’s ambition of reducing annual carbon emissions by 3 million tonnes by 2030, compared with the estimated emissions.
The mobile accommodation vessel «Haven», in use at the field from June onwards, has also been modified to utilise power from shore while in service at the Johan Sverdrup field. And based on current plans, the Johan Sverdrup field will be powered from shore already this autumn so that all the field’s power needs during the remaining hook-up and finalisation phase will be met with electricity supplied from shore.
