ULSTEIN® POWER VSG: Setting new standards in marine power efficiency
The ULSTEIN® POWER Variable Speed Generator (VSG) has been designed to optimise power generation on marine vessels by dynamically adjusting its speed to match load requirements. Together with technical measures and overall ship design, the operational results on the CSOV Olympic Boreas show a record-low 2.7 tonne fuel consumption per 24 hours during a week of DP operations.
Running the engines at variable speed optimises power production based on the vessel’s energy demand. Technical measures onboard have reduced power demand to 250-300 kilowatts under certain conditions. With such low power requirements, variable speed is significantly more efficient than constant speed, contributing to greatly reduced energy consumption per kWh produced.

Several companies in Ulstein Group have been involved in planning, developing, and building the Construction Service Operation Vessel (CSOV) for Olympic. The process started with an energy-efficient hull and thorough evaluations of systems and components. Once elements like main dimensions, seakeeping properties, and uptime were in place, Ulstein Design & Solutions AS analysed how the ship could become as energy efficient as possible, considering various system and propulsion solutions to achieve the best energy use and recovery results.
Developed by Ulstein Power & Control, the ULSTEIN POWER VSG redefines the standards of efficiency, sustainability, and performance in marine AC power systems. It substantially improves fuel consumption, emission reduction, overall system performance, and lower maintenance costs. The AC system is based on known robust technical solutions, giving the shipowners a reliable solution.
The ship owner experienced big fuel savings on the Olympic Boreas
The Olympic Boreas achievement represents close to a 50% reduction in fuel consumption compared to other CSOVs.
This highlights how the ULSTEIN POWER VSG, the technical measures, and the overall ship design can effectively enhance fuel efficiency and reduce operating costs, setting a new standard in the maritime industry.
Can be implemented in a wide range of vessels
The ULSTEIN POWER VSG's versatility makes it suitable for a wide range of marine vessels, including offshore vessels, expedition cruise vessels, and aquaculture vessels.
