Utilization of Wave Energy to Improve Propulsive and Seekeeping Performances of a Ship in Rough Weather

Hiroshi Isshiki

Abstract


According to IMO’s Energy Efficiency Design Index (EEDI), the CO2 emission of a ship must be cut 30% in 2025. This would invite serious speed drop of a ship in rough seas and deteriorate the safety of a ship drastically. The present paper discusses to utilize wave energies abundant in rough seas to overcome the danger. A very small hydrofoil fixed to the ship bow could reduce the ship motion and generate thrust enough to counter the speed drop mentioned above and make a ship much safer.


Keywords
