TenneT concludes agreement for service and maintenance of offshore cable systems

Transmission system operator TenneT has awarded Prysmian, one of the world’s leading companies in the supply of submarine HV systems, who will be in charge in partnership with N-Sea for the maintenance and servicing of TenneT cable systems in the German and Dutch North Sea - around 3,400 kilometres of offshore cables and 800 kilometres of nearshore cables.

A corresponding cooperation agreement between the companies was now signed in Bayreuth. The contract is initially for three years.

Jack Wattel, Director Subsea Cables N-Sea, says:

“N-Sea appreciates the trust offered by TenneT and Prysmian to be awarded such a strategic important subsea cable maintenance scope. N-Sea has built a unique and dedicated subsea cable repair & maintenance team with associated track record and specialised equipment to ensure flexible and quick measures in the event of a possible incident, for example. This agreement fits perfectly in our long-term N-Sea mission & vision to be an industry leader in subsea asset management. N-Sea looks forward to a good collaboration with TenneT and will deliver the agreement in a safe (zero harm) and efficient way.”

With Prysmian and N-Sea, TenneT has been able to sign up two leading providers of offshore cable solutions. Specifically, the contract provides for the monitoring, regular maintenance and, if necessary, repairs of the offshore cable systems operated by TenneT. Prysmian acting as the main contractor in this agreement in partnership with N-SEA will be responsible to cover the potential scopes of operation in the offshore & nearshore areas of the German and Dutch North Sea, by utilisation of state-of-the-art inhouse and external assets.

Both companies can draw on many years of experience and a large portfolio of different cable-laying and repair units, so that they can react flexibly and quickly in the event of a possible incident, for example. The cooperation agreement sets out fixed warranty periods within which potential maintenance, servicing or repair work on the cable systems must be carried out and completed.
