- Ulstein’s SX190 Zero Emission DP2 construction-support vessel is designed for offshore-wind operations using hydrogen fuel cells. The article says it can operate in dynamic-positioning mode for up to five days using hydrogen, and can switch to diesel-electric propulsion on low-sulphur fuel oil for longer missions. Hydrogen storage containers are on deck and can be refilled by truck or exchanged/lifted ashore where port bunkering is unavailable.
- The design reserves a second engine room for fuel cells. When liquid-hydrogen port infrastructure becomes available, it can be retrofitted with two below-deck liquid-hydrogen tanks, which the article says could extend hydrogen range to a month and free the deck. The page describes hydrogen as zero-emission at use when made with renewable electricity or natural gas plus carbon capture; lifecycle emissions are not quantified.
- The article calls the vessel design market-ready and said sea trials for a newbuild could take place as early as 2022, a now-past milestone whose completion is not confirmed on the page. It cites an offshore-wind market projection of USD 1 trillion by 2040.
- Linked to SDGs 7 (Affordable and clean energy) and 9 (Industry, innovation and infrastructure).
