World’s first wind-powered RoRo vessel secures EUR 9M in EU funding

Oceanbird and project partners have secured a Horizon Europe funding totalling EUR 9m to support building a RoRo sailing vessel. Over the next five years, all aspects of planning, building, and operating a wind-powered vessel, the Orcelle Wind, will be done.

“The Horizon Europe EU funding shows the concept stood up to the scrutiny of the EU funding authorities and that they had the confidence to give it their support,” says Roger Strevens, VP Global Sustainability at project coordinator Wallenius Wilhelmsen.

The grant of EUR 9m is divided between eleven partners – all bringing something unique to the table. Together, they represent a 360-degree perspective on wind propulsion – including weather routing, vessel design, supply chain orchestration and crew training to test rig installation on an existing vessel. The project’s scope is to make the Orcelle Wind ready for commercial trading.

Collaboration leads the decarbonization strategy

“The EU Funding project is based on a collaborative approach – we need strong partners to lead the way to zero emissions as soon as possible. We are proud to have a group of the best technical, operational, and academic partners, as well as one of our key customers, for the project. All have committed to working together to help make Orcelle Wind a reality,” says Strevens.

The EU project, called Orcelle Horizon, is a solid opportunity to combine the investments needed for full-scale demonstration and data capture with advanced models and tools for wing propulsion vessels. Beyond the demonstrator’s vessel, the partners will use the models and tools to develop advanced conceptual designs and operational plans for multiple vessel types to apply the wing solution.

A 220-meter-long wind powered vessel

Orcelle Wind is a wind-powered Pure Car Truck Carrier, a type of deepsea Roll On, Roll Off vessel. It will be 220 meters and have a capacity for over 7,000 cars, but will also be capable of carrying breakbulk and rolling equipment. Orcelle Wind is a crucial part of Wallenius Wilhelmsen’s fleet decarbonization strategy and the ambition is for it to commence sailing in late 2026 or early 2027.

Orcelle Wind is the first vessel from the Oceanbird concept for primarily wind-powered vessels. The concept shows that it is theoretically possible to reduce emissions from vessels by up to 90 percent if all emissions-influencing factors are aligned.

“The Oceanbird concept was developed through a partnership approach. We have seen the strength of gathering people from different sectors and companies to cover all perspectives. By working together, we will bring the Orcelle Wind project to life – and by that – take a huge step towards truly sustainable shipping,” says Niclas Dahl, Managing Director at Oceanbird.


Test rig installation

An important part of Orcelle Horizon is installing the wing sail test rig on the existing Wallenius Wilhelmsen vessel Tirranna during mid-2024. Oceanbird and Wallenius Wilhelmsen presented the test rig installation in a webcast live webcast from ABBA Arena.


This project has received funding from European Union’s Horizon Europe Framework program under grant no 101096673.
