Wärtsilä’s hybrid power module the Wärtsilä HY, has been granted Approval in Principle (AIP) by ABS another step forward to expand approval of its hybrid designs for power and propulsion.

This AiP follows another issued by ABS in 2017 for Wärtsilä’s hybrid propulsion tug designs.

“This AiP is an important step in the development of our eco-friendly hybrid propulsion system, which can be applied to a variety of vessel types,” said Giulio Tirelli, director, sales & business intelligence, Wärtsilä Marine Solutions.

“By working with ABS, we are demonstrating the viability of hybrid vessels in a range of applications and highlighting the capability to the US Market and further afield.”

Combined power

Mr Tirelli said that the Wärtsilä HY was developed by leveraging Wärtsilä’s technical strengths in both engine design and electrical and automation (E&A) systems.

The fully integrated hybrid power module combines engines, an energy storage system and power electronics, optimised to work together through a newly developed energy management system (EMS).

According to Mr Tirelli, it is the marine sector’s first hybrid power module of this type produced, thereby establishing a "new industry benchmark" in marine hybrid propulsion.

With the increased industry focus on environmental compliance and operational performance, many ship owners and operators are shifting their attention to electric propulsion and non-conventional sources of power.

Consequently, ABS has published an Advisory on Hybrid Electric Power Systems to provide guidance in the development of new concepts.
