The all electric superyacht came a step closer to reality. This follows a decision to by a British company to build the world’s first fully-electric offshore vessel
UK-based Bibby Marine has contracted with Spanish shipyard Armon to build the world’s first fully-electric Commissioning Service Operation Vessel (eCSOV).
The all electric vessel will feature Corvus Energy’s Blue Whale Battery Energy Storage System (BESS). It provides 25MWh of power and is the largest LFP (Lithium Iron Phosphate) battery system ever deployed at sea.
Battery power
The eCSOV will primarily run on battery power. It will be capable of operating fully electric for an entire day of operations. The all electric vessel incorporates dual-fuel methanol engines as a complementary power source. Thus significantly reducing carbon emissions while maintaining operational reliability.

The vessel’s advanced power distribution system utilises a DC grid architecture that optimises performance and minimises energy losses. A notable innovation is its ability to charge batteries while maintaining dynamic positioning during offshore operations. This is a first in the SOV market.
Key partners
The vessel’s construction will take place at Armon’s facilities in Vigo, Spain. It is a shipyard with over 60 years of experience in delivering high-quality vessels. The project brings together several key partners. These include Seaplace ship design for basic design and Longitude. They completed the original concept design.
The vessel is scheduled to begin supporting offshore wind farm operations in 2027. Corvus Energy will deliver components to the shipyard planned in 2026.
The so called green superyacht is an oxymoron just as is the eco friendly superyacht. These two goals however do drive the superyacht industry to build better and more environmentally friendly superyachts.
Both Lurssen in Germany and Feadship in Holland have made great inroads into alternative propulsion units for these craft. Furthermore they each continue to do so.
