Gwynt y Mor offshore wind farm

Client: Harland and Wolff

Location: North Wales

Date: 2011 -


Harland and Wolff secured the project from Siemens to design and build two offshore substation platforms for the Gwynt y Mor offshore wind farm; both were positioned in September off the coast of North Wales.

To ensure the highest level of Safety in A60 and AO boundaries throughout the operating life of the substation, Harland & Wolff chose CSD Sealing System's SLIPSIL Plugs and RISE Multi-cable Transit system instead of Block style Multi Cable Transits with the approval of RWE and Siemens.

CSD's experience of working in offshore industries and the performance of their products in arduous environments, helped win this work on one of the largest offshore wind farm's in the world.

Managing Director or CSD UK, David Ripley said,
"We understand that building offshore environments require the highest levels of safety and deliver solutions that are safe, cost effective and flexible. This is a very exciting project for CSD and we are delighted to be involved with the expansion of renewable energy sources, including offshore wind, around the UK."  

CSD has enjoyed a close working partnership with Harland & Wolff and Blackbourne M&E the Electrical contractor throughout the project. Blackbourne M&E additionally sub-contracted the installation of the 200 Cable Transits to CSD on the recommendation of Harland & Wolff.

The team of highly skilled installers lead by CSD 's Peter Litchfield and in partnership with CBL worked across the two offshore substations installing over 200 Cable transits in four weeks, ensuring the tight project schedule was completed on time. Blackbourne M&E, Harland and Wolff and ultimate clients Siemens & RWE were very happy with the quality of installation.

Frank Piggott, Electrical Engineering Manager at Harland and Wolff said,
"We chose the RISE multi transit system over a Blocks type compression system to provide the highest level of fire, gas and watertight integrity. We were extremely impressed with the professionalism and helpful approach of the CSD team, throughout the project. During the installation they worked seamlessly alongside both Harland and Wolff, Siemens and Blackbourne M&E, working to a very tight schedule, ensuring installation of 200 RISE cable transits on both platforms within 4 weeks."

CSD were glad to provide additional support in this prestigious project, by skill sharing and working with the customer as an integrated partner. CSD have been able to implement standards of installation across the board, resulting in a successful deliverance of a challenging project.
