The technology group Wärtsilä’s hybrid power module, the innovative Wärtsilä HY, has been granted Approval in Principle (AIP) by ABS, a global provider of classification and technical advisory services to the marine and offshore industries. This AIP follows another issued by ABS in 2017 for Wärtsilä’s hybrid propulsion tug designs.
The Wärtsilä HY was developed by leveraging Wärtsilä’s technical strengths in both engine design and electrical & 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.
“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,” says Giulio Tirelli, Director, Sales & Business Intelligence, Wärtsilä Marine Solutions.
“This is the latest example of how ABS is collaborating globally with innovative companies like Wärtsilä to expand approval of hybrid designs for power and propulsion options. 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,” says Demetri Stroubakis, ABS Director Equipment and Materials.
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. The ABS Advisory on Hybrid Electric Power Systems has been published to provide guidance in the development of new concepts.
