Reducing a lot on a few
And even more from a lot
Retrofits on existing vessels
To achieve a shipping revolution, we need to address the 60,000 commercial vessels on sea today. First focus is RoRo (Roll On, Roll Off) but we are also looking into other segments. An important part of the retrofit development is the test rigg to be installed on a Wallenius Wilhelmsen vessel during drydocking in mid-2024. Already this year, late 2023, Oceanbird will have a full-scale land-based installation.
Facts /Oceanbird Wing 560
Height: 40 meters (131 feet)
Width: 14 meters (46 feet)
Total sail area: 560 m2 (6028 f2)
Weight: Approx 150 tons
Two segments: Consists of a main sail and a flap, optimizing the aerodynamic forces by creating camber.
Materials: High strength steel and glass fiber. We aim to use as large amount of recycled material as possible and follow the progress of carbon neutral steel production in close cooperation with manufacturers.
Performance: One wing sail on an existing RoRo vessel at normal speed, can reduce fuel consumption from main engine with 7-10 % on favorable oceangoing routes. This means a saving of approx. 675,000 liters of diesel per year, which corresponds to approx. 1920 tonnes of CO2 per year.


Wing installation on existing vessel
In the middle of 2024, one Oceanbird Wing 560 will be installed on the Wallenius Wilhelmsen vessel Tiranna, as part of the EU project Horizon.
