    Wartsila and Stena to build the world’s largest hybrid vessels

    The technology group Wärtsilä will supply its hybrid propulsion system for three new RoPax vessel currently built for Stena RoRo, Europe´s largest ferry company, according to the company's release. Two of the ferries will have a battery capacity of 11.5 MWh, making them the marine industry’s largest hybrid vessels to date. This battery power is approximately double that typically being used currently for hybrid propulsion. The order was placed in May 2022.

    The ships have been designed and developed by Stena RoRo and Brittany Ferries and they will be long term chartered to Brittany Ferries for operation between Portsmouth in the UK and French ports of St Malo and Caen. Wärtsilä had already earlier been contracted to supply a broad range of solutions for the vessels, including the main and auxiliary engines, gearboxes, controllable pitch propellers (CPPs), thrusters, the fuel gas supply system, Nacos navigation and automation as well as integrated control alarm and monitoring system. The ships will be capable of operating with either LNG fuel or batteries.

    The vessels will be equipped with the latest generation Leclanché energy storage system – the Navius MRS-3 – which has both a size and weight advantage versus comparable marine batteries.

    Important elements of hybrid vessels include the ability to integrate multiple vessel systems and real-time optimisation of the on-board energy system. Wärtsilä combines a wide range of system expertise across a broad range of ship power and propulsion machinery. Combining the benefits of the hybrid propulsion system and shore power leads up to 15% GHG emissions saving to a conventional diesel mechanical propulsion system.

    The vessels are being built at the China Merchants Jinling (Weihai) Shipyard. Delivery of the ferries is expected to take place in 2024 and 2025.

    Since 1977, Stena RoRo has led the development of new marine RoRo, cargo and passenger concepts. The company leases about fifteen vessels to operators worldwide, both other Stena companies and third parties. Stena RoRo specializes above all in applying its technical expertise to the design and production of new vessels and the conversion of existing vessels for providing tailored transport solutions to its customers.
