New wind farm cabling contract is most complex project of its type ever!

By Grimsby Telegraph | Posted: 16 Oct 2017

CURRENTLY delivering the Hornsea onshore cabling works that are now skirting around North East Lincolnshire, contractor J Murphy & Sons Ltd has been lined up to deliver the same for Triton Knoll offshore wind farm.

While the current Dong Energy project will serve the world’s largest array, the Innogy project will represent the most complex. 

The challenge of installing 60km of onshore cable infrastructure has been described as “unprecedented in the UK” not least of all due to the extent of the engineering required to complete it.

More than 300 separate horizontal direction drills will be required to cross obstacles, with the largest ever carried out in the UK to date being 100 during the widening of the M25.

It will stretch from the point of landfall at Anderby Creek to a new-build substation at Bicker Fen, south west of Boston, with two separate team on northern and southern sections. 

The team behind Triton Knoll said it provides the best opportunities yet for local suppliers.

Project director James Cotter said: “This will be an unprecedented engineering challenge, where Triton Knoll and Murphy are pushing the boundaries of innovation and technology to deliver one of the longest ever underground cable installations linked to an offshore wind farm.

“Our arrangement with Murphy really demonstrates how we are working towards delivering our target of at least 50 per cent UK content across the lifecycle of the project. We anticipate important opportunities for local businesses both in terms of traditional sub-contracted works and wider support services.  We are determined that local companies will have visibility of contracts and the opportunity to bid for work on our project and we believe that local companies can be successful.  In this way, we hope to play a role in the retention of local jobs and skills and see investment flowing into the local communities.

“As this contract develops, Murphy will become increasingly visible in the community, working with local people, landowners and businesses to ensure everyone remains up to speed with the works being carried out. They will be joining our Local Liaison Committee meetings and will be supporting our forthcoming supply chain events in the months to come.

“We are incredibly pleased to have a business with such experience and presence on board, and welcome them to the Triton Knoll team.”

In preparation for the works, Murphy will set up a new project office close to the cable route, which is eventually likely to house over 100 UK staff. In addition, the civil engineering and specialist excavation and drilling works required will attract a large UK-based workforce for the duration of the installation.

Murphy is a well-established construction and engineering company with more than 60 years’ experience in delivering large infrastructure projects, with expertise in onshore and offshore cable laying, horizontal directional drilling, tunnelling, cable systems and civils route design.

Murphy chief executive Steve Hollingshead said: “This is one of the biggest power projects that Murphy will have worked on and it’s a real marker of the upward direction in which our business is going, as we continue to develop and grow. To have been chosen as preferred supplier for such a large and prestigious project shows that we are trusted by innovative companies like Innogy to deliver world-class infrastructure projects that will improve people’s lives.

“It’s an incredibly exciting and complex project, and we’re looking forward to working closely with Innogy to provide first-rate results.”
