Hornsea One Wind Farm

Great Britain (1,2 GW)


In May 2016, Bladt Industries won an order for the supply of three substations for the Hornsea Project One Offshore Wind Farm – a Ørsted Project.

The construction contract was unique and historical, as it was the first time in Bladt Industries’ and their long-term partner Semco Maritime’s history that a contract has been signed for three substation topsides at the same time. The first phase of the project was initiated right after the signing of the contract and the substations was delivered during the spring and early summer of 2018.

Bladt Industries was responsible for the construction of steel structures for all substations, while Semco Maritime will facilitate the production of LV electrical works, including E&I, design, onshore construction and off-shore commissioning.

96 foundations
In January 2017, DONG Energy awarded Bladt Industries with the contract for the construction of 96 transition pieces for the same project - each with a weight of approximately 330 tons and a diameter of 6 metres.

The Hornsea Project One Offshore Wind Farm is located in the North Sea approximately 120 kilometres off the
coast of Yorkshire in Great Britain.
