Technology group Wärtsilä will supply an integrated hybrid propulsion system for the two new Ro-Ro vessels under construction at the China Merchants Jinling shipyard (Weihai) Co., Ltd for Stena RoRo.

The ships will be the world’s first methanol fuelled hybrid Ro-Ro vessels and will operate in the Stena Line Irish Sea system.

Each vessel will be equipped with two Wärtsilä 32M multi-fuel engines capable now of operating on methanol fuel and with ammonia ready notation.

Wärtsilä will also supply the MethanolPac fuel storage, supply and control system, the gearboxes, two controllable pitch propellers (CPP), three bow thrusters, the NACOS navigation system, three Wärtsilä 20 auxiliary engines, and the hybrid electric system consisting of shore power, batteries, shaft generators, converters, transformers as well as the Energy Management System making it all work together.

Each vessel will also benefit from the Wärtsilä Hybrid Solution, optimising the fuel consumption today and allowing for future full green operation. The vessels will also be equipped with Wärtsilä shore power solution enabling carbon-free operations when the vessels are in port.

The 147m ships will have 2,800 lane metre capacity.

They are scheduled for delivery in June and November 2025.
