Stena unveils energy-saving RoRo design

The 240m Stena Futuro has a raft of features including wing sails, hybrid propulsion and an air lubrication system designed to optimise efficiency and reduce emissions.

“The mission is to develop the most efficient and competitive vessel possible for a specific cargo capacity, using today’s available technology,” explained Nicolas Bathfield, project manager at Stena Teknik, who has been involved in developing the concept.

“The goal is for the vessel to have the lowest fuel consumption on the market.”

Designed for the transportation of semi-trailers and cars, Stena Futuro’s hull and superstructure have been optimised for the most efficient use of cargo space possible.

The vessel will have hybrid propulsion, batteries and engines that can run on several different fuels. Solar panels will also help meet the ship’s electricity needs.

The concept also includes four 40m wing sails, which can be retracted when needed. Recent tests by the developers and Swedish research institute RISE have shown that using the sails could save fuel by as much as 15%.

“We also confirmed that the vessel meets all requirements for stability and manoeuvrability in scenarios such as sudden wind shifts or quick course changes,” continued Bathfield.

The hull of Stena Futuro will also be equipped with an air lubrication system and a waste heat recovery system to meet onboard heating needs as well as supporting electric power generation.

Currently, there is no finalised plan for the production of Stena Futuro.
