The hybrid power conversion will be conducted early next year on the Maersk Minder, a deepwater anchor handling tug supply (AHTS) vessel.
According to Wärtsilä, this may be the world’s first AHTS hybrid battery conversion. The HY system should lower the vessel’s fuel consumption, and carbon emissions, by 15%, also reducing its maintenance requirements.
The main components in the system are the hybrid drive, the energy storage system, and the transformer, with control and monitoring performed by the energy management system.
The system is designed to achieves peak shaving, spinning reserve, and improved efficiency through running the engines at optimal load and using the batteries to absorb much of the load fluctuations.

The Wärtsilä HY Module containerized hybrid battery power and energy storage system.
Wärtsilä also supplied the engines, thrusters, propeller arrangement, seals and bearings for the vessel, along with integrated automation and planned maintenance systems.
