In a crucial step towards a more sustainable maritime future, Wallenius Marine is continuing advanced testing to develop the world’s first wind-powered PCTC (Pure Car and Truck Carrier) vessel . This innovative proposal is currently in a decisive phase, with rigorous testing being carried out in a wind tunnel in Gothenburg, Sweden – one of the most advanced in Europe.
Wallenius Marine and wind energy
Wallenius, known for its focus on energy efficiency and the development of green technologies, has stepped up its efforts to transform shipping through the use of wind power. The aim is to achieve emission-free transport and reduce the environmental impact of commercial fleets – essential in a sector that accounts for a significant portion of global CO₂ emissions. To do so, the company has partnered with experts from academic institutions and research organisations such as RISE, KTH and Oceanbird.
Critical tests of the PCTC wind power vessel
[post_relacionado]Between 6 and 9 December, researchers will conduct a series of critical tests to validate the design of the wind-powered PCTC vessel. The tests focus on the interaction between the hull and the state-of-the-art wing sails.
This approach combines aerodynamic optimisation with the ship’s hull structure, allowing for accurate data on system performance under extreme conditions. A full-scale model measuring 5×2 metres, weighing 1.2 tonnes, simulates the ship’s behaviour in the tunnel at speeds of up to 250 km/h.
Vessel optimization with predictive models
The simulation model obtained from these tests will be used to refine the wing control systems, which will be critical to ensuring the long-term performance of wind-powered PCTC vessels. This data will not only validate the final vessel design, but will also help develop new predictive models for other wind-powered vessels .
The innovation of this project dates back to 2017, when the idea of a wind-powered sailing ship began to take shape in the Wallenius blueprints. With each step they take on this journey towards cleaner shipping, Wallenius continues to demonstrate their leadership in sustainable commercial shipping. In 2025, the Oceanbird wing sail will be tested onboard Wallenius Wilhelmsen’s vessel Tiranna, marking another milestone in the transition to zero emissions.
