General – Survey Work
NKT has completed inspection survey and remediation work on the East West interconnector that links Ireland and Great Britain.
The specialized inspection and remediation work allows the owner, EirGrid Interconnector Designated Activity Company (EIDAC), a subsidiary of the EirGrid Group, to ensure that the cable is brought back to optimal conditions.
To optimize performance and enhance longevity of its interconnector, EIDAC, recently had NKT inspect the East West HVDC interconnector between Ireland and Great Britain. The inspection survey is part of a long-term service agreement between the two companies.
Commenting on the work, EirGrid’s Chief Operations Officer, Rodney Doyle said: “EirGrid has a long-standing partnership with NKT as we work together to secure the condition of the East West Interconnector. As the interconnector is a critical piece of infrastructure between Ireland and Great Britain it is essential that it is maintained in an optimal condition. The recent survey showed the necessity of remediation work on sections of the cable. These works are now complete ensuring the continuity of supply between Ireland and Great Britain.”
The survey conducted by NKT including characterization of seabed conditions along the cable led to concrete mattresses and rock bags being placed above exposed sections of the East West interconnector.
Carrying out periodic cable inspection surveys ensures that the cable can withstand extreme conditions and perform safe operations. A precise analysis and mitigation plan is a key element for preventing cable failures and reducing downtime. NKT’s offshore engineering centre can analyse cable survey data, providing the customer with 360-degree cable expertise.
