Murphy secures £100m Triton Knoll offshore wind farm contract

By Grimsby Telegraph | Posted: 20 Jun 2018

Murphy has formally secured the £100 million contract to 'bury' the onshore cable for Triton Knoll offshore wind farm.

It follows the winds on Hornsea Projects One and Two for the civil engineering specialist, which is a familiar sight in northern Lincolnshire.

The contract comes as the 860MW Innogy project begins its initial works onshore, in preparation for the main construction of the substation and cable route later this summer, with sign-off anticipated soon.

Murphy, already announced as preferred supplier, has already been working on the design and are now preparing to install the project’s onshore cable circuits, which stretch from the point of landfall near Anderby Creek, to a new Triton Knoll Substation at Bicker Fen, near Boston.

Hornsea, currently in construction, runs from Horseshoe Point to North Killingholme. 

The Triton Knoll installation will present one of the biggest engineering challenges of its kind, with almost 60km of onshore underground cable to install, and more than 300 obstacles to be crossed by individual horizontal direction drills – three times more than what’s believed to be the previous UK record for an infrastructure project.

Triton Knoll project director Julian Garnsey said: “We are delighted to award this contract to our supply chain partners Murphy. This contract secures significant investment into the UK supply chain, which will open up additional opportunities for more local firms to support Innogy’s flagship offshore wind farm, Triton Knoll.

“Murphy has already engaged local firms during preliminary works for Triton Knoll, and has demonstrated their willingness to continue working with us to ensure we can maximise opportunities from our investments for local and UK businesses, throughout the project lifecycle.

 “We’re very excited that Murphy is now on board as we prepare to start onshore construction in the coming weeks and months.”

Initial works to prepare for the onshore main construction gets underway this month at various locations along the onshore cable route and will include the following activity:

  • Installation of temporary office accommodation
  • Construction of several temporary construction compounds
  • Preparation of various access roads along the route
  • Establishment of speed restrictions several major roads
  • Topsoil stripping along parts of the onshore cable route

Public information days to ensure the local community are fully informed of activity around the project will take place from June 26 to June 29. 

Murphy will shortly begin setting up new project offices on the cable route where it intersects the A16, which affords good transport links to the rest of the county. It already enjoys such a position on the road further north, at Waltham Airfield, for Hornsea.

The location will eventually house over 100 UK staff. In addition, the civil engineering, specialist excavation teams and horizontal directional drilling works required to deliver these major works will attract a large UK-based workforce for the duration of the installation, and Murphy has already begun to bring on board local companies following a recent successful Triton Knoll supplier event earlier this year.

Murphy chief executive John Murphy 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 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.”
