WSP | Parsons Brinckerhoff has been appointed by National Grid North Sea Link Ltd to provide cable manufacturing quality and inspection services on a $2.1bn interconnector, which will link between the Nordic and British markets.
With a planned capacity of 1,400 MW, the NSN interconnector will generate enough electricity to power nearly three quarters of a million homes, greatly helping both countries’ energy security.
National Grid North Sea Link Ltd and Statnett are working together to construct what will be the world’s longest subsea interconnector.
When completed, this will consist of approximately 720 kilometres of High Voltage Direct Current (HVDC) cable. The interconnector which aims to be operational in 2021, will link Kvilldal in Norway and Blyth in the UK.
A team of quality consultant engineers will provide third party inspection and audit services during the manufacture of the submarine and land cables supplied by Prysmian from Arco Felice in Italy. WSP | Parsons Brinckerhoff’s involvement will ensure that the cables are manufactured and tested to specification, and that all the quality documentation is in place prior to shipment and installation.
WSP | Parsons Brinckerhoff has a track record working on high profile energy projects including the £1.5bn Galloper Offshore Wind Farm, the £2bn Gwynt y Môr Offshore Wind Farm, and the 500MW East-West interconnector which has been voted as Engineers Ireland’s Project of the Year 2013.
Michael Carr, assistant project manager, WSP told Power Engineering International, the company’s role is all about limiting the risks for the client and preventing issues from the start.
“The key to achieve this is to work alongside Prysmian to identify any potential manufacturing quality issues prior to installation, as costs to repair the cable once installed can be significant.”
“We’ve provided quality and inspection services on the Greater Gabbard offshore wind farm project as well where we carried out the inspection services during the manufacture and final testing.”
“WSP | Parsons Brinckerhoff is keen to demonstrate their track record in this sector to capitalise on the ever increasing number of interconnector projects around the world.“
Testing will be ongoing until 2021, with manufacturing and tests at Prysmian planned over the duration.
