ULSTEIN® POWER Variable Speed Generator (VSG)

The ULSTEIN POWER VSG helps you optimise power generation on your vessel.

Variable speed, maximum performance

The ULSTEIN POWER VSG represents a groundbreaking advancement in marine power technology. By combining variable speed generation with cutting-edge automation and energy management, Ulstein Power & Control has delivered a solution that not only meets but exceeds the demands of modern maritime operations. As the industry continues to prioritise sustainability and efficiency, the ULSTEIN POWER VSG stands out as a key enabler in navigating the future of green marine power solutions.

The ULSTEIN POWER VSG is a sophisticated Variable Speed Generator system designed to optimise power generation on marine vessels. It includes an advanced load sharing strategy between fixed and variable speed generators operating in parallel. Unlike traditional fixed-speed generators, which operate at a constant speed regardless of demand, the ULSTEIN POWER VSG dynamically adjusts its speed to match load requirements, delivering power to the grid within the sweet spot of energy efficiency. This results in significant improvements in fuel consumption, emission reduction, and overall system performance.

Big fuel savings on the Olympic Boreas

The Olympic Boreas achievement represents a nearly 50% reduction in fuel consumption compared to other CSOVs.

This highlights how the overall ship design, the technical measures, and the power system can effectively enhance fuel efficiency and reduce operating costs, setting a new standard in the maritime industry.

Benefits of the ULSTEIN POWER VSG

The ULSTEIN POWER VSG offers a multitude of benefits that set it apart from conventional power systems:

Enhanced fuel efficiency:: By adjusting the generator’s speed to match the exact power demand, the ULSTEIN POWER VSG minimises fuel consumption, resulting in significant savings in fuel costs.
Reduced emissions:: The optimization of fuel usage directly translates to lower emissions, helping vessels comply with stringent environmental regulations.
Improved system reliability:: Integration with a battery energy storage system ensures a dynamic and stable power supply, even during peak demand or generator fluctuations.
Lower maintenance costs:: Variable speed operation improves combustion and reduces mechanical stress on the diesel engine and associated components, resulting in a longer lifespan and lower maintenance requirements. Operating at a variable speed has the potential to increase the time between services by 50-70%.
The best of both worlds:: Combining a robust low voltage AC solution with cutting-edge power conversion and energy storage systems, the ULSTEIN POWER VSG ensures unparalleled reliability and sets a new benchmark for efficiency in the maritime industry.

Applications

The versatility of the ULSTEIN POWER VSG makes it suitable for a wide range of marine vessels, including:

Offshore vessels: Provides reliable, dynamic and efficient power for DP operated vessels like, SOVs, subsea, and support ships.
Expedition Cruise vessels: Ensures a smooth and efficient power supply, enhancing passenger comfort and operational reliability.
Aquaculture vessels: Highly variable power demands across operations benefit from ULSTEIN POWER VSG, ensuring a significantly reduced environmental footprint.
