Triton Knoll today confirmed UK firm J Murphy & Sons Limited (Murphy) as its preferred supplier to install the entire 60km underground cable route, while providing the wind farm’s best opportunities to date for local suppliers.
As preferred supplier, Kentish Town based Murphy will design and install the project’s critical onshore cable circuits, which will stretch from the point of landfall near Anderby Creek, to a new-build substation at Bicker Fen.
Triton Knoll is an innogy-owned(1) offshore wind farm, located 32kms off the Lincolnshire coast. It has a planned installed capacity of 860MW(2), capable of supplying the equivalent of over 800,000 UK households per year, with renewable electricity.
The installation will present one of the biggest engineering challenges of its kind, with almost 60kms of underground cable to install, and over 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.(3)
Triton Knoll 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% 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 CEO 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.”
Triton Knoll was awarded a Contract For Difference (4) in September 2017, and expects to trigger a capital expenditure investment of around £2billion into much needed UK energy infrastructure. This will enable the delivery of some of the lowest cost energy generation for UK consumers.
The project is now progressing towards a financial investment decision likely in 2018 with full onshore construction starting shortly after, and offshore construction starting in 2020. First energy generation could be as early as mid-Q1 2021, with the project expecting to begin commissioning in 2021.
