abstract

A ship harnessing all its required energy from the wind, waves and sun is proposed. The ship employs five wingsails and two spring-loaded wavefoils — one ahead of the bow and the other astern of the stern. In addition, the deck is covered with solar panels, which generate electricity for use aboard the ship. The wind speed is calculated from wave scatter tables, by finding the wind component of the waves from the two-peaked Torsethaugen wave spectrum and assuming unlimited fetch and fully developed sea. Wingsail and wavefoil forces are calculated using a dynamic stall model and implemented in a time-domain ship simulator. Statistical estimates of the ship speed are calculated for the route Ponta Delgada, Azores - Funchal, Madeira, round-trip, for all four seasons. The expected ship speeds are about 6 knots, and the standard deviations are about 5 knots.
