500MW HVDC interconnector between County Wexford (Ireland) and Pembroke (Wales) with approximately 160 km of offshore cable (WSP: lead technical advisor since March 2018; clients engineer through construction).
WSP was appointed by Greenlink as lead technical advisor from March 2018 and acted as the client’s engineering adviser through feasibility, procurement, detailed design reviews and construction monitoring. The firm provided technical assurance across HVDC control/protection and converter equipment, prepared technical specifications used in procurement (including for the selected turnkey converter and cable suppliers), and supported measures required to make the scheme bankable. WSP integrated with the client team, called on multi-disciplinary expertise (ecology, geotechnical, environmental) and continued in an owner’s-engineer style role through construction and into commercial operation (reported to continue through 2024).
