American Bureau of Shipping (ABS) has granted its Approval in Principle (AIP) to Wärtsilä’s new hybrid power module called Wärtsilä HY.
The fully integrated module was developed using Wärtsilä’s technical expertise in engine design, as well as electrical and automation (E&A) systems.
It combines engines, an energy storage system, and power electronics to work together through a new energy management system (EMS).
Wärtsilä HY is customised to be used for vessel types and can be optimised for specific operating profiles.
Wärtsilä Marine Solutions Sales and Business Intelligence director Giulio Tirelli said: “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.”
Last year, Wärtsilä received an AIP from ABS for its hybrid propulsion tug designs.
ABS Equipment and Materials director Demetri Stroubakis said: “We recognise the significant economic and environmental benefits of hybrid-powered vessels and are committed to supporting the development of alternative power applications that optimise efficiencies.”
In view of growing importance on environmental compliance and operational performance, several ship owners and operators are shifting their focus from traditional propulsion to electric propulsion and non-conventional sources of power.
ABS has published an Advisory on Hybrid Electric Power Systems to offer guidance in the development of these new concepts.
