Cable Route Survey Required for VIKING Link

National Grid Interconnector Holdings Limited and Energinet.dk, which are jointly developing a new HVDC power cable between Great Britain and Denmark known as VIKING Link, have invited tenders for a cable route survey extending across the North Sea between the two countries.

The cable route survey will include geophysical survey, geotechnical investigations, cable-crossing investigations with ROV and Benthic investigations.

Tenderers are invited to submit a response to pre-qualify for the services related to the cable route survey by October 23. The services will include offshore representation on marine vessels as well as onshore support with logistic management and technical consultancy related to the marine operations.

The objectives of the tendered services are to provide offshore representation on the marine vessels on behalf of the developers to monitor progress and performance of the surveyor in terms of Safety, Health, Environment and Quality, breakdown of time, accept/disagree on standby for weather/break-down, technical performance of vessel and measurement systems as well as performance of the crew.

National Grid Interconnector Holdings Limited and Energinet.dk intend to award the work to maximum of two tenderers.

The cable route is approximately 610 km long and 500 m wide. However, this might vary as the final settlement of the route is still ongoing.

The developers require the provision of two offshore client representatives on 24 hr vessels and one offshore client representative on 12 hr vessels. The number of vessels is not settled. The services are expected to be delivered and completed in 2016.
