Preparation works are underway for the North Sea Link Interconnector project.

Both Graham Construction and North Sea Link Interconnector have held a start-up meeting to prepare for a converter station to be built in Blyth.

The meeting took place ahead of construction on the North Sea Link Interconnector, a 1,400 MW HVDC electricity transmission interconnector connecting Kvilldal in Norway and Blyth in England.

As part of the preparatory works, Graham will carry out earthworks at the main converter site and develop the detailed design, where applicable.


A 'cut and fill' process will be employed during earthworks, the amount of material from cuts roughly matching the amount of fill needed, minimising the amount of surplus material arising.

In addition, slotted land drainage, storm outfall and inspection chambers will be built with pipework being installed by means of a pipe jack from the southern area of the main site, under Brock Lane, through the agricultural field and discharging into the Sleekburn via a reinforced concrete headwall.

Other preparatory works include the provision, installation and removal upon completion, of site set up including offices, welfare facilities and secure containers.

The North Sea Link Interconnector project is scheduled for completion by 2021.
