Wärtsilä has announced the introduction of a unique hybrid product, the Wärtsilä HY - a fully integrated hybrid power module combining engines, an energy storage system, and power electronics optimized to work together through a newly developed energy management system.
It is the marine sector's first hybrid power module of this type.
There is a notable trend in the marine sector towards hybrid propulsion solutions, which are anticipated to represent a significant percentage of all contracted ships within the coming 10 years. The new energy management system represents the latest generation integrated control system, and has been specifically designed for this application.
The Wärtsilä HY will increase operational efficiency and flexibility, resulting in lower fuel consumption, reduce emissions and improved vessel performance. When operating in 'Green Mode' zero emissions can be achieved. Smokeless operation is also achievable at all load points and in all operating modes, thanks to a new patent pending automation procedure. The reduction in engine operating hours lowers maintenance requirements and extends the intervals between overhauls, 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.
Classification society, Lloyds Register has issued an Approval in Principle certificate for the Wärtsilä HY.
The Wärtsilä HY will have dedicated versions for each category of vessels. While the first versions being made available will be designed for tugs and medium sized ferries. Wärtsilä also sees big potential in other types of vessels as well.
Wärtsilä has received its first order for the Wärtsilä HY from Italy-based Rimorchiatori Riuniti, the biggest owner and operator of tugs in the Mediterranean Sea region. The company's fleet comprises some 100 vessels. The Wärtsilä HY will be dedicated to a project for a new 80 TBP (tons bollard pull) harbor tug.
