Our colleagues Stan Logghe, Project Manager of the Greenlink project, and Wouter Vermeersch, Director Subsea Cables, attended the inauguration event last week in Wexford, Ireland. After a 60-day test period, the Irish Minister for Climate, Environment and Energy officially announced the commissioning of the interconnector.
One of Europe’s most important energy projects
Greenlink is one of the most significant energy infrastructure projects in Europe. The interconnector has the capacity to power up to 380,000 households and doubles the energy exchange capacity between Ireland and Great Britain. For Ireland, it is a key step toward importing lower carbon electricity from the UK, helping the country meet its climate goals.
About the project
The Greenlink Interconnector stretches 190 kilometres and links the coasts of Ireland and Wales via the Irish Sea. We were responsible for installing and protecting 160 kilometres of subsea cable. The remaining 30 kilometres were installed on land.
We carried out the project in two campaigns. In October 2023, our cable-laying vessel Connector installed the first 80 kilometres of cable, running from Wales to the middle of the Irish Sea. In spring 2024, we completed the second half, starting from the Irish coast. The two cable sections were then joined together at their meeting point in the Irish Sea.
At the same time, we deployed our offshore support vessel Symphony and our in-house developed trencher Swordfish to bury the cable into the seabed. In areas where the seabed was too hard for trenching, our rock installation vessel Simon Stevin protected the cable with rocks.
