Green, hydrogen-powered offshore turbine installation vessel from Ulstein
- Published 30 June 2022; updated 30 September 2026; estimated reading time 2 minutes. Marked available; listed under Offshore wind / Installation, Maritime / Ship design and ship’s equipment, Hydrogen / Use, and Energy.
- The ULSTEIN J102 wind-turbine installation vessel pairs a hydrogen fuel-cell system with a small battery. The article says it can operate in zero-emission mode for 75% of operational time, particularly while jacked up for crane work. Hydrogen is stored in removable containers that can be refilled by truck or taken ashore for bunkering, avoiding reliance on port hydrogen facilities.
- Ulstein reports the current configuration reduces CO₂ by 4,000 metric tonnes and emissions per turbine-installation cycle by 25% compared with conventional power systems. The page does not define the 4,000-tonne time period or calculation boundary. It says the additional cost is below 5% of capital expenditure; these are company-reported estimates.
- The system is intended to adapt as hydrogen infrastructure develops. The article called the design market-ready and said a newbuild’s sea trials might occur as early as 2023, a past target whose completion is not confirmed on the page. It cites a USD 1 trillion offshore-wind market projection by 2040.
- The listed SDGs are 6 and 9; SDG 6’s page description refers to facilitating offshore-wind deployment, which appears mismatched to the goal of clean water and sanitation.
