Wärtsilä announced the introduction of a fully integrated hybrid power module, combining engines, an energy storage system, and power electronics optimised to work together through a newly developed energy management system (EMS). The Wärtsilä HY is the marine sector’s first hybrid power module of this type produced and it is exposed at this year’s Norshipping Conference.
The new EMS represents the latest generation integrated control system, that creates advanced interaction with the ship’s onboard systems. The system provides operational efficiency and flexibility, resulting in lower fuel consumption, reduced 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. Furthermore, the reduction in engine operating hours lowers maintenance requirements and extends the intervals between overhauls.
“This development opens the door to a new era of marine technology that would have been unimaginable until very recently”, stated Giulio Tirelli, Director, Marine Engineering, Wärtsilä Marine Solutions.
The Wärtsilä HY will have dedicated versions for each category of vessels. The first versions being made available will be designed for tugs and medium sized ferries, but the company sees potential in other types of vessels as well.
Maritime classification society, Lloyds Register (LR) has issued an Approval in Principle (AIP) certificate for the Wärtsilä HY. The certificate is based on technical material and safety analyses, concerning normal operation of the system and a presentation of risk scenarios.
LR’s Marine & Offshore Director, Nick Brown commented: “LR is proud to issue an Approval in Principle certificate to the Wärtsilä HY hybrid power module. LR, like Wärtsilä, is committed to tackling the big challenges facing the industry, especially those environmental challenges related to carbon emissions.”
The Wärtsilä HY is being officially launched at the Nor-Shipping conference and exhibition being held in Oslo, Norway from May 30 to June 2, 2017.
