OPTIWISE

OPTImised WInd Supported vEssels

Running

The Horizon Europe research project Optiwise aims to improve and demonstrate energy savings using wind propulsion as well hydrodynamic improvements in propulsion.

Background

The maritime industry is facing a huge chllange to reduce its Green House Gas emissions according to the IMO ambition, and the gradually introduced regulations to advance this effort. Carbon free or neutral fuels are assumed to be the main solution. However, sufficient and affordable supply of such fuels is highly uncertain, which means that energy saving on board is expected to be increasingly important, both environmentally and economically.

With Optiwise we are building on R&D already under development among some of the consortium partners in the last years. Fruitful and promising progress has been made with the introduction of new devices to the market, with some 15 ships sailing commercially with wind propulsion in the world fleet. However, wind propulsion is so far mostly applied without re-considering the overall ship design and operations. Whereas that fits within a “business as usual” scenario, it does limit the attainable savings. With OPTIWISE we are re-thinking the design process and energy management of ships with wind propulsion, while still making sure that these ships conform to common operational and regulatory requirements. We thereby expect to enable and showcase much higher savings than what can be seen in the present market applications” says Rogier Eggers of MARIN.

OBJECTIVES
The EU call requested solutions for energy savings of at least 10% for single measures and 20% for combined measures. The overall objective of Optiwise is to develop and employ holistic design and control methods for ground-breaking new ship concepts utilising wind propulsion while considering realistic operational scenarios. With these methods average energy savings between 30% and 50% are expected when compared to equivalent conventional ships while ensuring operational feasibility in a realistic wind climate.

The Optiwise project will further pursue its objectives through close inspection of three operational use cases which include a bulk carrier with Flettner rotors, a tanker with wing sails and a passenger vessel with a AeroRig system with rigid panels. These cases will provide a relevant sampling of the world fleet, such that the methods developed in the project should be able to cover the majority of the seagoing shipping fleet. While the wind propulsion type is preselected for each ship type, the exact implementation and change of the ship design and energy management is fully open to further performance enhancement.

SCOPE
The project scope involves extensive simulations where different disciplines, such as aerodynamics, hydrodynamics, routing and energy management are holistically brought together. Great attention will be applied to ensure realistic operational applications of the developed designs. Thus, these will be complemented with basin tests to assess manoeuvring and seakeeping, bridge simulations to assess crew operation, and land-based wind propulsion tests to verify better control.

DELIVERABLES
The project will deliver open guidelines for Integrated system optimisation with wind propulsion and Smart measurement and control for best operation. The guidelines will be demonstrated in experimental model tests, bridge simulations and measurements on a full scale land based wind propulsion unit.

BUDGET & PLANNING
The project will run for three years, with a budget of 5.1 million euro.
