en.Wedoany.com Reported - Oceanbird has installed its first 40-meter wing sail system on the car carrier "MV Tirranna," operated by Wallenius Wilhelmsen Lines. The vessel, measuring 237 meters in length with a deadweight tonnage of 71,000 tons, will undergo system testing in the coming months.

Designed by the joint venture between Swedish engineering company Alfa Laval and Wallenius Marine, the wing sail system is named the Tiltable Rigid Wing Sail Wing 560. It is tailored for tankers, bulk carriers, and oil tankers, suitable for passenger and cargo vessels, bulk carriers, and oil tankers exceeding 200 meters in length. The system provides maximum unit power for large vessels, with a design life of 25 years and minimal component and maintenance requirements.

The customized wing sail version for the "Tirranna" stands 46 meters tall from base to tip (with the wing sail section at 40 meters), has a width of 14 meters, and a total system weight of approximately 200 tons. The mast and base are made of carbon steel, while the leading edge, trailing edge, and flap panels use PET core material and glass fiber composites. The hydraulic system is equipped with backup piping, hoses, and an additional pump to ensure the wing sail can always be folded and stowed.

The Wing 560 is a passive system with extremely low energy consumption. The shipowner expects each wing sail to consume 6 to 10 kilowatts during normal operation. The system operates independently but is integrated with vessel functions, including the common alarm system, energy management system, and data exchange.
