J Murphy & Sons has already designed the project’s onshore cable circuits for its electrical system and is now preparing to install it, the company stated.
It will also carry out the main construction of the substation and cable route later this summer.
Innogy secured support for Triton Knoll in the UK’s contract for difference (CfD) auction in September and will comprise 90 of MHI Vestas’ V164-9.5 turbines. It is due online in 2021/22.
The project’s electrical system will stretch about 60 kilometres from the point of landfall near Anderby Creek to a new substation at Bicker Fen.
J Murphy & Sons described installation of the electrical system as "one of the biggest engineering challenges of its kind" and added that installing the underground cables will require using horizontal drills to overcome more than 300 obstacles. This is believed to be three times more than the previous record for UK infrastructure.
Initial works to prepare for onshore construction start in will June 2018 and include installing temporary offices, preparing access roads, and stripping topsoil along the cable route.
The construction and engineering firm has also started recruiting UK-based suppliers.
