Construction and engineering firm J Murphy & Sons [Murphy] will break what is believed to be a UK record when it installs 60km of onshore cable infrastructure for the £2bn Triton Knoll wind farm.
Set 32km off the Lincolnshire coast, Triton Knoll will have an installed capacity of 860MW when it opens in 2021. Last month the project won a Contract for Difference, the government’s scheme to boost less established forms of renewable energy such as offshore wind.
As preferred supplier, Murphy will install all of the onshore cable circuits running from Anderby Creek to a new substation at Bicker Fen in Boston.
More than 300 separate horizontal directional drills will be carried out to lay the cables, smashing the current UK record: during the widening of the M25, 100 separate drills were used.
“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,” said Murphy chief executive Steve Hollingshead.
“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.”
Two teams will lay the cable, divided into north and south sections. The remaining 49km of the cable will run offshore. Triton Knoll will eventually hold 90 V164-9.5 MW turbines at 187m tall, which are more powerful than the V164-8.0 MW turbines used at the Burbo Bank Extension offshore wind farm near Liverpool.
