Offshore installation company Offshore Heavy Transport (OHT) has confirmed it is now under contract to install the foundations for the Dogger Bank A and B projects in the UK
Following an announcement in July 2020 that it had been awarded a contract for the transport and installation of foundations at the Dogger Bank A offshore windfarm, the installation contractor has confirmed that the contract for the second phase, Dogger Bank B, has now also been signed.
The project will also use OHT’s specialist newbuild vessel Alfa Lift. The vessel will undertake the Dogger Bank B project after completing installation work on Dogger Bank A.
Alfa Lift will transport and install all of the monopile foundations and transition pieces for each of the two 1.2-GW phases of the project, between 2022 and 2024.
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 awards are subject to Dogger Bank A and B reaching financial close, which is expected in late 2020.
