OHT is proud to announce their preferred supplier status for the foundation installation at the world’s largest offshore wind farm Dogger Bank.
Under the agreement, OHT’s new build vessel Alfa Lift will carry out the transport and installation of monopile foundations and transition pieces for the Creyke Beck A and B wind farms.
Utilising a single vessel, the foundations will be transported to the offshore site, approximately 130km off the north-east coast of England, and installed in water depths of up to 35 metres. With her unrivalled cargo capacity, the Alfa Lift heavy installation crane vessel will carry 10 monopiles and transition pieces on deck per voyage. The monopiles will be among the largest ever installed.
The Dogger Bank Wind Farms, being developed by SSE Renewables and Equinor, were recently awarded Contracts for Difference (CfDs) in the UK government’s latest auction round.
“We are humbled and honoured to be selected as the preferred supplier for this momentous project, bringing the world’s largest and most capable offshore wind installation vessel to the world’s largest windfarm, to support the world’s most powerful turbines”, said Torgeir E. Ramstad, CEO OHT.
“We are focused on bringing significantly increased efficiencies to the market with our new vessel, contributing to the achievement of the lowest ever strike price. We very much look forward to working with SSE Renewables and Equinor in a cooperative and transparent way to ensure the safe and timely execution of these key projects”.
OHT is keen to engage with the local supply chain in the UK and, in parallel to this announcement, pleased to launch their online supplier portal. Companies interested in working with OHT can register their services and their locations via the OHT website.
Paul Cooley, SSE Renewables Director of Capital Projects, said: “Dogger Bank Wind Farms is paving the way for future offshore wind developments, not just in the UK but globally, by utilising some of the most innovative and efficient technology on the market, like the Alfa Lift vessel, and we are very pleased to have OHT working with us as we deliver this ground-breaking project.”
Steve Wilson, Project Director, Dogger Bank Wind Farms, said: “The monopiles that will be installed at Dogger Bank will be amongst the largest ever used on an offshore wind farm and we needed a vessel that would allow us to deliver our project in the safest and most efficient way. OHT’s Alfa Lift’s capability offers us this solution and we look forward to working with them to deliver Dogger Bank Wind Farms.”
Halfdan Brustad, Vice President for Dogger Bank at Equinor, said: “We are pleased to have OHT as our contractor for monopile installation. By bringing new, innovative and efficient vessels into the market, like the Alfa Lift vessel, we are helping to revolutionize the offshore wind industry. We need new entrants that can think differently and make the industry even more competitive. We look forward to working with OHT to make Dogger Bank a success.”
OHT’s Alfa Lift vessel, of Ulstein design, will arrive to market in 2021. She will be the world’s largest and most efficient custom-built offshore wind foundation installation vessel, featuring a 3,000-tonne state-of-the-art crane and more than 12,300 square metres of available deck space. The main deck will incorporate a fully automated skidding system, whilst the forecastle deck will carry transition pieces and mission equipment. The vessel has a capacity to carry a total payload of up to 51,250 tonnes.
“It is with great pleasure that we accept this award which will propel OHT into a leading position in the offshore wind market. We will provide all necessary support from the owners of the company to ensure successful project execution to the benefit of all stakeholders involved”, said Arne Blystad, Chairman and majority owner of OHT.
Transport and installation of monopiles and transition pieces is expected to be performed between 2022 and 2024.
