Xodus supporting major cable installation project as it reaches key stage

A newly launched purpose-built vessel has docked in Aberdeen Harbour in preparation for its maiden project to install two subsea power cables connecting Caithness to Moray.

The NKT Victoria, which has just arrived following its maiden voyage from Sweden, is being used to lay 113km of subsea cable from Noss Head in Caithness to Portgordon in Moray as part of Scottish and Southern Electricity Networks’ £1.1bn Caithness-Moray project.

The purpose-built cable laying vessel will lay the cables in two campaigns – the first from Noss to the midpoint of the cable route and the second from Portgordon to the end of the previously laid cable.

The milestone follows on from the recent successful clearance of rocks and boulders along the proposed route of the Moray Firth and the ongoing work to create a trench in preparation for the cable installation. Once the cable has been successfully installed, the specialist plough which is being used to create the trench will be brought back and reconfigured to backfill the trench using the seabed material previously excavated­ during the trenching operation.

Lead Project Manager Brian Wilson said: “We are delighted that this specialist cable laying vessel has arrived safely following its maiden voyage from Sweden. The installation of the subsea cable is one of the major components of the Caithness-Moray project and the arrival of the NKT Victoria marks a very exciting milestone for SSEN and our contractors as we look forward to the subsea cable installation over the summer.” 

Thies Helbig, ABB Project Director, added: “The arrival of the NKT Victoria marks an exciting stage in the project that represents the culmination of years of design and preparatory work. With the subsea cable now ready for installation the Caithness-Moray link is really starting to take shape.”

Ame Abrahmsson, NKT Project Manager, said: “The laying of this subsea cable is one of the first major projects in the strategic partnership between NKT and ABB. The NKT Victoria offers state-of-the-art cable laying capability with DP3 dynamic positioning as well as a remotely operated vehicle featuring cameras and sonar to enable high-precision laying of high-voltage offshore cables. The vessel also uses electrical power from the shore when in harbour, rather than running on board diesel generators, so that cable loading is carried out using environmentally friendly power.”

Andrew Wylie, Xodus Group Scotland Operations Director said: “This is an exciting time for the team as the project hits another key stage in the process. Projects involving submarine interconnection demand rigorous risk management and know-how in multiple technical disciplines. With our years of experience on diverse projects, we are providing marine engineering and installation advice for all aspects of the submarine cable installation and providing guidance as the Employer’s Representative on board the vessel.” 

The Caithness-Moray project is required to transport renewable electricity from across the north of Scotland to areas of demand across Scotland and beyond.


The vessel is expected to depart Aberdeen on Saturday morning in preparation for the cable installation.
