Offshore wind’s ship problem is growing
the firm made back in 2020 when it said that the global fleet wouldn’t be enough to meet demand after 2025.
Massive, specialized vessels are required to carry wind turbine components out to sea and install them. With just over 30 of these vessels navigating the world’s seas in 2020, according to Rystad, offshore wind projects already have to vie for time with a limited number of ships. A growth spurt in turbine technology will exacerbate the problem even further.
Taller turbines can reach stronger winds, while longer blades can harness more power. New turbines are the size of skyscrapers, dwarfing previous designs. Between 2010 and today, the amount of wind power turbine can harness, on average, has more than doubled from 3 MW to 6.5 MW. By the end of the decade, more than half of turbines installed globally are projected to be even larger than 8 MW.That’s quickly making more ships — even those just built this decade — obsolete.
are capable of carrying behemoth next-generation turbines, according to Rystad’s 2020 analysis. The firm measures demand for the ships in “vessel years” that represent how much time is needed with the vessels to build offshore wind projects. Rystad says demand for vessels capable of installing turbines larger than 9 MW was “nonexistent” in 2019. By 2030, it expects demand for such ships to reach 62 vessel years.
