The bulk carrier in the CHEK project uses aerodynamically optimised wing sails to capture the forces of the wind in propelling the ship forward using renewable energy. The resistance of the vessel travelling through the water is reduced by deploying a carpet of microbubbles beneath the hull. This reduces friction, lowering the vessel’s fuel consumption and emissions. The vessels are further optimised using automated vessel routing and weather predictions to minimise energy use and work in synergy with the engine and wind propulsion systems.
Technologies applied on the CHEK’s bulk carrier: solid wing sail, air lubrication system, ultrasound antifouling system, waste heat recovery system, gate rudder, automated route optimization.
D2.4. Life-Cycle Assessment of CHEK vessels
In order to see the advantages of CHEK vessels when applying technologies and alternativefuels, it is necessary to use a comprehensive approach to evaluate the environmental performance of both vessel types on a Life-Cycle Assessment (LCA)basis. The LCA method was used as a tool to assess the environmental impacts ofthe vessels. The purpose of this deliverables is to present the LCA work on the bulk carriers and the cruise vessels, based on the data gathered from digital twin model some data from technologies providers. The results will give the holistic view on the positive impacts of technologies working on synergies and alternative fuels (bio-LNG, and green hydrogen) on the future vessel design.
