NKT to install second-phase Johan Sverdrup power cables

Equinor and its partners have issued a letter of award to NKT for an NOK1 billion-plus (US$121-million) EPCI contract for two HV subsea cables.

These will supply power from shore for the second phase of the Johan Sverdrup development in the Norwegian North Sea. NKT’s programme will include testing of the cables which will be connected to the Sverdrup field centre.

Previously the company fabricated and installed the power cables for the first phase of Johan Sverdrup, with installation completed this spring.

The new consignment will be fabricated at the company’s plant in Karlskrona, Sweden, and laid from Haugsneset in Tysvær municipality north of Stavanger to the Johan Sverdrup field centre.

There the power cables will be pulled up to the second processing platform, to be installed in 2022. They will be buried in the seabed or covered by rocks, as required.

Previously Equinor assigned Siemens delivery of the high-voltage direct current transformer equipment to be installed on the second processing platform (P2) at Johan Sverdrup and at Haugsneset, and Aibel all construction work related to the onshore converter station at Haugsneset.

Equinor estimates that these programmes will cut carbon-dioxide emissions from Sverdrup field by 460,000 metric tons/yr (507,063 tons).
