Technology
Optiwise will employ a wide range of technological improvements to achieve its objectives.
Total System Optimisation
Stage 1
Operations
Voyage simulations will provide a main mission profile consisting of wind conditions, ship operations, sea states and extreme conditions that will be used as primary optimisation goal.
Wind Propulsion
Fast predictions models will be made with Machine Learning methods of high performance wind propulsion systems that can be used in the global design optimisation.
Global Design
Multi-objective optimisation of the global ship, wind propulsion system, simplified propulsor and rudder. Targeting objectives such as: fuel consumption, manoeuvring and seakeeping.
Stage 2
Detail Design
Detailed design of the aft ship, propeller, energy saving device and rudder with the objectives to reduce required power and cavitation risk for a group of conditions dominating fuel consumption and cavitation under-water noise.
Power Plant
An adapted propulsion, power and energy system - including its control strategy - is required to have optimal efficiency and avoid instability for a large range of different torque-rom conditions.
Design & Control
Two distinguished features of the total system optimisation will come under further examination to:
Develop a multi objective design and optimization approach suitable for the increased degrees of freedom with wind propelled ships.
Develop sensors, actuators and control algorithms for better control of wind propulsion and propeller propulsion.
Develop an energy management system for wind assisted ships, which provides performance monitoring and voyage optimization towards lower-emission and higher energy efficiency operation.
Use cases
The project will also work towards advancing current innovative and promising wind propulsion concepts in both new developments and retrofit solutions to further test safety, operational feasibility and their efficient integration into the global vessel design. Targeted energy savings for the total system optimisation, including each wind propulsion concept, lies between 30 and 70%.
ANEMOI’s
Rotor Sails
ANEMOI will develop the designated key innovation areas for a bulk carrier fitted with rotor sails. The rotor sails work using the Magnus effect; by spinning the rotor (using an electric drive) air flow is forced around the rotor, thereby creating (amplified) lift and drag forces.
AYRO’s
OceanWings
AYRO will work on developing the designated key innovation areas for a tanker with their OceanWings solution. The OceanWings are reefable and automated multi-element wing-sails.
Chantiers de l’Atlantique’s
Solid Sail
The Chantiers de l’Atlantique team will develop the designated key innovation areas for a passenger ship with the Solid Sail system. The Solid Sail system is set-up with a mainsail and a furlable jib on one tiltable mast. The mainsail is made from many individual solid panels connected with moveable hinges in between.
