The Wärtsilä HY is a fully integrated hybrid power module combining engines, an energy storage system, and power electronics optimised to work together through a newly developed energy management system. It is the marine sector’s first hybrid power module of this type produced, thereby establishing a new industry benchmark in marine hybrid propulsion.
Through combining its unique range of in-house competences, Wärtsilä has turned a complex system into an innovative single product that delivers unrivalled and guaranteed performance. The Wärtsilä HY power module is tailor-designed for individual vessel market segments and can be optimized for specific operating profiles, thanks to a new generation energy management system (EMS).
The new EMS represents the latest generation integrated control system, and has been specifically designed for this application. It creates an outstanding means of interaction with the ship’s onboard systems.
The Wärtsilä HY ensures that the overall vessel performance is greatly improved compared to operating on conventional machinery solutions or hybrid solutions, while the higher level of redundancy promotes increased safety. Other benefits include instantaneous load acceptance with rapid response to step-load changes, entire system certification and guaranteed performance.
