Wallenius Marine trials ship design for world’s first wind-powered PCTC vessel
Wallenius Marine is conducting advanced wind tunnel tests for the world’s first wind-powered PCTC (Pure Car and Truck Carrier) vessel.
The tests are being carried out in Sweden’s Gothenburg, at one of Europe’s most advanced wind tunnels, with wind speeds of up to 250 km/h.
Wallenius Marine is gathered with experts from RISE, KTH, and Oceanbird in Gothenburg for a series of crucial tests to validate the latest design for wind-powered PCTC vessels, a groundbreaking innovation in maritime transport. These tests are expected to confirm the design and contribute to the development of new data simulation models for wind-powered ships.
The test areas include:
The interaction between the vessel’s hull and six high-tech wing sails.
Testing the optimal distance between hull and wing for maximum performance.
Testing three different types of command bridges and their impact on the vessel’s performance.
How “off-design conditions” affect the ship’s operation, such as when a wing sail is positioned at the wrong angle or location.
Data for the development of wing control systems.
The tests are being conducted by RISE Maritime Department (former SSPA), which has also constructed a 5 x 2 meter model using advanced technology. The model weighs 1.2 tons and is used to simulate the full aerodynamic performance of the ship in the wind tunnel.
Previously, wing sails have been tested independently without a hull, but this combination of hull and multiple wings in a large tunnel with a full-scale model makes this test unique.
“We are currently at a central stage in the design process where we want to ensure that our design meets all technical and operational requirements before we finalise the tender design,” said Carl Fagergren, Senior Project Manager at Wallenius Marine.
