MARIN, together with the consortium outlined below, has initiated ‘Optiwise’, an EU funded research and innovation project aiming to improve and demonstrate energy savings using wind propulsion.

Our overall ambition is to develop and employ holistic design and control methods for groundbreaking new ship concepts utilising wind propulsion. With these methods we expect to realise average energy savings between 30% and 50% when compared to equivalent conventional ships, while ensuring operational feasibility in a realistic wind climate.

Optiwise will consider three operational use cases. Extensive simulations within these use cases will be done covering aerodynamics, hydrodynamics and marine power systems. These are holistically brought together in routing and energy management. There will be a keen additional focus on realistic operational applications of the designs using basin tests to assess manoeuvring and seakeeping, as well as bridge simulations to assess operations from the crew’s point of view. In order to increase effective thrust in uncertain wind conditions, full-scale, landbased tests are also performed to verify
smarter control methods for Flettner rotors.
