OPTIWISE set out in 2022 to develop and employ holistic design and control methods for ground-breaking new ship concepts utilising wind propulsion while considering realistic operational scenarios. The consortium is coordinated by MARIN and supported by partners CORE, SSPA/RISE, Anemoi, Ayro, Chantiers de l'Atlantique, FIMC, Wartsila Netherlands, UNIGE, and Euronav. With this mix of expertise and knowledge the relevant aspects of WASP ship design are covered. The project is organised in 5 technical WPs covering ship design (WP 1) and economic assessment (WP 5) which support the designs of three ships with three WASP systems in WP 2, 3, and 4. The WASP systems and ship designs considered are a bulk carrier with Anemoi rotor sails (WP 2), a tanker with Ayro oceanwings (WP 3), and a passenger vessel with CdA Solid sail (WP 4).
