Oceanbird has installed its first 40-meter wing sail system on the MV Tirranna, a car carrier belonging to Wallenius Wilhelmsen Lines, a vessel measuring 237 meters in length and 71,000 DWT. The system will undergo testing in the coming months.
The joint venture between the Swedish engineering company Alfa Laval and Wallenius Marine has designed the tiltable rigid Wing 560 sail for passenger and cargo ships, bulk carriers, and tankers over 200 meters.
The tiltable rigid Wing 560 sail, custom-designed for tankers, bulk carriers, and oil tankers, offers maximum power per unit for large vessels.
The version adapted for the Tirranna is 46 meters high from the foundation to the top (the wing itself is 40 meters) and 14 meters wide. The system weighs approximately 200 tons; the mast and base are made of carbon steel, and the flap, front, and rear panels are made of PET Core and fiberglass composites.
The hydraulic system is installed with backup lines, hoses, and an extra pump to ensure the wing can always be stowed.
Wing 560 uses minimal energy as it is a passive system. Shipowners can expect between 6 and 10 kW per wing sail during normal operation. The design is conceived for a 25-year lifespan with minimal components and maintenance.
The wing sail is an independent system but integrates with vessel functions such as common alarm, power management system, and data exchange.
