The subsea cable route is expected to be up to 170km long. The final length of the cable will depend on the findings of subsea surveys as well as ongoing consultation with key stakeholders. Initial cable route selection centred on desk-based work and the assessment of known data and constraints. Following assessment of environmental and technical constraints, the route that offers the best solution to challenges identified while maintaining the shortest route solution will be chosen as the preferred route.
Marine surveys began in 2018. The results will not only aid the selection of the preferred cable route but also the appropriate installation and protection methods to be adopted.
Technical and environmental assessment
As part of the project development, a series of technical and environmental assessment studies are being carried out to establish the viability of all the proposed converter sites and cable routes and to consider any potential impacts and opportunities arising from the project development. Greenlink is a cross-border project and no adverse cross-border impacts are expected.
Further detail on the marine surveys and technical and environmental and assessments can be found in our latest version information brochure.
