Norwegian energy giant Statoil said that cable laying work has been launched to supply power to the Johan Sverdrup field development in the North Sea from shore.
The task has been given to cable-laying vessel NKT Victoria, which has started laying out cables from the Johan Sverdrup converter station at Haugsneset, located near Kårstø in Norway.
Statoil expects NKT Victoria to lay out about 200km of power cables to the Johan Sverdrup development by the month end.
Along with the power cables, a fibre-optic cable will also be bundled, which will help in communications and monitoring of operations from shore, said the Norwegian firm. The cables are expected to export power from the shore to the Johan Sverdrup field for more than 50 years.
Statoil said that once the cables reach the offshore field at the month end, the next step will be to pull them to the riser platform, which houses the converter station for the $14.61bn first phase of the development.
After this step, the cables will be linked prior to the launch of preparations and testing of the system, said the operator of the Johan Sverdrup field.
Statoil’s Geir Bjaanes, who is responsible for subsea, power and pipelines for the Johan Sverdrup project, said: “For the next three weeks or so we will be laying almost 10 kilometres of cables every single day.
“We have spent much time together with NKT preparing for this, but this will put our skills to the real test, our number one priority being safety and ensuring high quality in execution.”
The company expects the Johan Sverdrup field to be powered by the electricity from shore in the autumn of 2018.
It also said that after the second phase of the development is commissioned in 2022, the Johan Sverdrup field will also facilitate power from shore to be transmitted to the remaining fields on the Utsira High which include the Edvard Grieg, Gina Krog and Ivar Aasen fields.
Last month, Statoil said that the first of four topsides of the Johan Sverdrup project has been installed following the placing of the last module of the riser platform. The phase 1 of the Johan Sverdrup development is anticipated to commence production in late 2019.
