Ulstein's first full-electric offshore supply vessel
In 2023, we set a new standard for sustainable offshore operations.
Zero emissions, maximum efficiency.
Offshore energy needs a cleaner, smarter supply solution
The offshore industry faces unprecedented pressure:
- Stricter emission regulations.
- Rising operational costs.
- Rapid offshore wind expansion.
Traditional supply vessels can’t meet these demands without compromise. The future calls for zero-emission operations and more innovative logistics.

Introducing Ulstein’s full-electric supply vessel
Designed for the offshore energy market, this vessel is the first of its kind, combining right-sizing principles with full-electric propulsion to deliver sustainable, cost-efficient supply operations. Right-sizing is a holistic approach to assessing main parametres, hull design, deck area, cargo capacity, deadweight, and accommodation.


Pushing for progress
We aim to be one step ahead in solving key challenges for the maritime industry. By innovating and shaping tomorrow's solutions, we create value for our customers, shareholders, employees, and society at large.
