Marine renewable energy expertise

As an industry leader in tidal and wave energy installation, James Fisher Marine Services has been chosen to work on a cable installation project for Wave Hub in Cornwall.

Hot on the heels of its success with MeyGen in Scotland, the team at James Fisher Marine Services (JFMS) is thrilled to have landed another significant tidal energy installation project.

Wave Hub is the world's largest and most technologically advanced site for the testing and development of offshore renewable energy which aims to accelerate and support the development of offshore renewable energy technology.

The contract includes the installation of four cable tail extensions set-up to transport power from wave energy devices linked to the Wave Hub, to the main export cable which goes ashore. Work began in May with the mobilisation of a specially chosen offshore construction vessel to Falmouth, and the transpooling of 7km of cabling onto installation reels at A&P docks in Falmouth.

The team has been tasked with transpooling the cables from the client supplied storage reels onto specifically designed offshore installation reels. The cables will then be connected to the Wave Hub (effectively a giant underwater electrical junction box), and secured to the seabed with rock bags hoisted via an in-house hydraulic lifting beam. A survey vessel will be mobilised to conduct a post-lay cable survey to prove they are fit for purpose.

JFMS's bid manager, Lucas Lowe-Houghton, explains;

"This is the first time JFMS has deployed its new in-house survey equipment which uses 3D sonar on an ROV to analyse the cable touch down to make sure it's been laid correctly. We used further 3D laying software to predict the dynamic movements of the cable during the lay to ensure design parameters were preserved. 

This is another multi-million pound project which places us at the centre of the wave and tidal industry in the UK. The company beat off tough competition but our ability to demonstrate our technical capabilities, understand the environment and plan out our projects, supported by our long-standing proven track record stood us head and shoulders above our much larger competitors."

JFMS also enlisted the support ofMojo Maritime (Mojo) which worked with Tidal Energy at Ramsay Sound in Pembrokeshire. Mojo's pioneering marine project planning system, Mermaid, was crucial to the win. It enabled the team to provide accurate data to support the costing model and duration of the project - giving a significant advantage.

Sister company, JF Offshore will also be involved in the project, supplying back deck equipment to support installation operations.
