The High Voltage Alternating Current (HVAC) cables will make up the onshore cable network, connecting power from the 860MW offshore wind farm to the new onshore substation at Bicker Fen.

According to Triton Knoll, this milestone marks the delivery of the first major elements of the project’s onshore electrical system and will be ready for installation along the cable route in the summer.

The cables are being delivered to the port on 28 cable drums, typically 4.5m x 3.5m in size, with the majority expected to arrive on 24 March.

The drums will then be transported on heavy goods vehicles, via the A16 to a secure storage compound near to the project’s cable route, Triton Knoll said.

Each cable drum weighs between 17 to 26t and contains between 1,023m to 1,690m of HVAC cable. In total there are 306 cable drums required for the entire onshore cable route, which adds up to more than 360km of cable.

The Triton Knoll offshore wind farm, being developed by Innogy Renewables UK Ltd, in partnership with J-Power and Kansai Electric Power, will comprise 90 MHI Vestas 9.5MW turbines scheduled to be operational in 2021.
