Offshore support vessel CONNECTOR at work in the bay at Freshwater West (south of Milford Haven waterway) for the Greenlink project.

Greenlink is a proposed subsea and underground electricity interconnector cable between the existing electricity grids in Ireland and Great Britain (GB), with a nominal capacity of 500 megawatts (MW). Greenlink will provide a new grid connection between EirGrid’s Great Island substation in County Wexford (Ireland) and the National Grid’s Pembroke substation in Pembrokeshire (Wales).

The cables will be buried underground and offshore the cables will be buried in the seabed or laid on the seabed with protection, if burial is not practicable.

The subsea cable route was expected to be up to 170km long. Following the completion of subsea surveys the cable route is now circa 160km long.

Marine surveys, which took place in 2018 and included geophysical and geotechnical surveys, were undertaken to ensure that an appropriate cable route was identified. The research vessel. FRANKLIN (IMO 8301797) was primarily used in these surveys.
