Following the award of a preferred supplier agreement in November 2019, OHT Alfa Lift has signed a contract to transport and install the foundations for the first phase of the Dogger Bank Wind Farm, Dogger Bank A
The contract for the second phase, Dogger Bank B, is expected to follow in due course.
The project will be the monopile installation debut for OHT’s specialist newbuild vessel Alfa Lift which is currently under construction at CMHI’S shipyard in China.
Alfa Lift will transport the monopile foundations and transition pieces to the offshore site, more than 130 km off the northeast coast of England and install them in water depths up to 35 m, using its 3,000-tonne crane.
Dogger Bank project director Steve Wilson said, “It is great to confirm the OHT Alfa Lift vessel for Dogger Bank A. Their vessel is one of the most innovative heavy transportation and installation vessels on the market and we are very pleased to have them working with us as we deliver this ground-breaking project.”
Equinor vice president for Dogger Bank Halfdan Brustad said, “We look forward to working with Norway’s OHT to make Dogger Bank a success. The Alfa Lift is an excellent example of the new, efficient and innovative vessels which we need to revolutionise the offshore wind industry and make it even more competitive.”
The foundations will be among the largest ever used for offshore wind and are expected to be installed at Dogger Bank A between 2022 and 2023.
OHT said the vessel, which is of Ulstein design, will arrive in Europe in good time before project mobilisation. Construction is progressing as expected and has experienced no significant delays due to the Covid-19 pandemic.
The Dogger Bank windfarm is being developed by SSE Renewables and Equinor, with first power expected in 2023. The contract is subject to the project’s final investment decision.
