DONG Energy has ordered three substation topsides for its Hornsea Project One offshore wind farm from Bladt Industries. Bladt and its partner Semco Maritime deemed the order as historical, since this is the first time that a contract has been signed for three topsides at the same time.
Bladt Industries is responsible for fabricating the steel structures of the substation topsides. The fabrication will take place in close cooperation with Semco Maritime who will be in charge of LV electrical works, including E&I, design, onshore construction and offshore commissioning.
Each of the three substation topsides for the offshore wind farm will have a weight of approximately 2,800 tonnes and have a span of approximately 36x23x20 metres.
The first phase of the project has already been initiated. According to plan, the first substation topside will be ready for delivery in spring 2018.
“We have a deep respect for the great responsibility DONG Energy has provided us with in the delivery of three substation topsides for this strategic project. For a longer period, we have been working in close cooperation with Semco Maritime on goal-oriented initiatives to bring down the costs of substations. With three substation topsides, we can continue this process and contribute with a further reduction of the long-term price per produced kWh from wind farms – also known as cost of energy (CoE),” said Jan Kjærsgaard , CEO, Bladt Industries.
“Bladt Industries and Semco Maritime form a strong team within this highly specialised field of engineering ensuring benefits for our clients and businesses alike. The wind power business plays an increasingly important role for us, and we strive to be an even more attractive supplier to our clients,” said Steen Brødbæk , CEO, Semco Maritime.
The Hornsea Project One offshore wind farm will have a capacity of 1.2GW in total, with 174 wind turbines and four substations. The offshore wind farm will be situated in the North Sea, 120 kilometres off the coast of Yorkshire in the UK.
