Eon has completed installation of 116 MHI Vestas V112 3.45MW turbines at its 400MW Rampion offshore wind farm off the coast of Sussex in the UK.
Jack-up vessels MPI Discovery and MPI Adventure carried out the work, which started in March.
The turbines have 80-metre towers and have rotors with blades measuring 55 metres in length, Eon said.
The company added that further construction and commissioning work will now continue on both the offshore and onshore substations, as well as on the onshore cable route.
Work on the project’s 112km of array cables is also complete.
Rampion development and stakeholder manager Chris Tomlinson said: “We’re especially proud to have achieved this remarkable feat, installing all 116 turbines ahead of schedule in just over six months.
“We now look forward to Rampion’s first generation of electricity later this year and to working towards completion and full operation in 2018.”
Eon, the Green Investment Group (formerly Green Investment Bank) and Canadian energy company Enbridge are investors in the wind farm.
