The Trump administration had little focus on renewables, and regulatory difficulties did not help off-shore construction. State waters extend to three miles offshore, beyond which federal rules apply; which meant that most windfarms had to obtain licences from both. The Jones Act, of 1920, which specifies
that only US-made ships may carry cargoes between US ports and applies also to the specialist vessels, which are needed to install windfarms, has limited the number of such vessels available. The Biden administration, however, as part of its climate agenda announced in January this year a record-breaking offshore wind lease sale, covering nearly 500,000 acres (200,000ha) off the coast of New York and New Jersey. It is expected to generate as many as 80,000 new jobs in the wind-energy sector as well as up to 7 gigawatts of clean electricity. Financial incentives will be available for wind-turbine materials that are made in the U.S., but foreign-made components are not barred; which is why Seasight Davits, of Ringkøbing in Denmark, was able to announce, at the end of March 2022, its first US orders. They are supply contracts for a total of 77 windfarm davit cranes for projects off the US East Coast. The cranes each have an outreach of 4 meters and a lifting capacity of 1 ton. “Signing these contracts was of particular importance to us as it led to our establishing our third overseas subsidiary, Seasight Davits US,” said Alex Kristensen, Seasight CCO. “In January 2022, Seasight Davits US became a reality with its registration in the State of Delaware.

The next step is to register in New York State, where the subsidiary will be located. “The timing for winning these projects is
very fortunate for us,” said Kristensen. “We saw how the US offshore wind industry was starting to develop rapidly, so it became part of our strategy to expand with a US subsidiary within a certain timeline to become part of the supply chain over there.” As well as the supply contracts, Seasight
Davits is hoping to receive a two-year service agreement. “Service agreements make things even more interesting because they, unlike a supply contract, gives prospects of long-term and continuous

work, which is very important when entering a new market and even more so when establishing a new company. We will start manning up with personnel in the US from the beginning of 2023 as we need to have a local team of technicians ready when the annual service campaigns of the davit cranes commence, which is expected to be in 2024.” The davit cranes will be produced at
Seasight Davits’ facilities in Denmark. Deliveries are scheduled to start at the end of the year. Hydro-electricity supplied around
16% of global power in 2019. Hydro is renewable and generally considered ‘clean’ – although studies suggest that the area of water in large man-made reservoirs emit methane in quantities that are by no means negligible – methane being around 30 times more powerful than CO2 as a greenhouse gas. The environmental impact of damming a large river can also be huge. Small-scale hydro schemes, however, avoid much of these criticisms. Mona Lifting, of Anglesey in Wales, has supplied overhead cranes to nuclear stations and to CERN; but also the design and commission of a manual overhead travelling crane specifically for fitting in small hydro power stations. “This crane is usually fitted at the construction stage and can be used to install the turbine and other equipment without requiring any power input,” says operations director Gethin Jones. “The crane is modular and has versions from 1 ton to 30 tons.
