Wärtsilä’s hybrid power module Wärtsilä HY, has been granted Approval in Principle (AIP) by the classification society ABS.
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). It is the marine sector’s first hybrid power module of this type produced, thereby establishing a new industry benchmark in marine hybrid propulsion, according to Wärtsilä.
“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. 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,” said Giulio Tirelli, director of Sales & Business Intelligence, Wärtsilä Marine Solutions.
With the increased industry focus on environmental compliance and operational performance, many shipowners and operators are shifting their attention to electric propulsion and non-conventional sources of power, Wärtsilä noted. The ABS Advisory on Hybrid Electric Power Systems has been published to provide guidance in the development of new concepts.
