Application of hybrid CRP-POD propulsors on ultra large twin screw containerships to increase propulsive efficiency, reduce GHG emissions and improve navigational safety

Reducing fuel consumption and minimizing greenhouse gas emissions are essential for the shipping industry. All possible ways to achieve the environmental objectives should be considered. Conventional propellers are known to have low efficiency. Most marine propellers on cargo ships waste about 40 percent of their energy in the form of axial losses, vortex generation, noise production, cavitation etc. Recovery of such losses is one of the main ways to contribute to a greater, rational and environmentally friendly use of energy. Ultra-large container ships are ships that, on the one hand, have the highest individual carbon footprint, but on the other hand, benefit from the economy of scale and transport a huge amount of goods around the world. Therefore, this type of vessel is an ideal target for action to investigate energy-saving solutions. The overall aim of the project is to minimize fuel consumption, improve maneuverability and increase navigation safety by introducing three highly efficient innovations for ultra-large container ships (ULCS): two-propeller configuration, azimuth thrusters and counter-rotating propellers. Research on these topics will be carried out using advanced numerical CFD methods, in a modern towing tank fully equipped to study such a complex hydrodynamic problem as a twin-crp-pod solution. The maneuvering tests will be carried out using large manned models on a natural lake. All technical studies will be accompanied by life cycle analyzes that will be carried out using the most complex tools, including the assessment of negative environmental impacts on land, sea and air resources. The project consortium consists of a world-leading hydrodynamic research institute, a propeller designer, a design office, a port pilot organization, a vessel maintenance training provider and a technical university. The consortium ensures that the project's objectives are properly achieved by building up a wealth of knowledge on propeller-hull interactions, structural integrity and manufacturing processes.

  • Influence of windsurfing fin stiffness distribution on the lift-drag characteristics
    Publication

    - Year 2023

    This article addresses the problem of determining the hydromechanical loads generated by flexible hydrofoils. The research was done on the example of the composite windsurfing fin for the RS:X monotype class. Despite the assumption of fins identity, everyday practice showed that variations of mechanical properties occur and strongly affect their performance. Therefore, we decided to study the differences between the windsurfing...

  • Scale effect in the self-propulsion prediction for Ultra Large Container Ship with contra-rotating propellers
    Publication

    - Year 2023

    This article addresses the problem of the scale effect for an Ultra Large Container Ship (ULCS) with a novel twin-crp-pod propulsion system. Twin-crp-pod steering-propulsion arrangement is an innovative solution that gains from three well-known systems: twin-propeller, contra-rotating propellers and pod propulsors. It is expected that applying the twin-crp-pod system to the analysed Ultra Large Container Ship will increase propulsion...
