POSSIBILITY OF USING RIGID SAIL (WING) FOR ADDITIONAL SHIP PROPULSION

In this work a rigid sail (wing) is considered as additional ship propulsion. Additional ship propulsion by sails is well known and used (windship). Wings can be simple symmetrical Or complex. Present material mid control technologies makes possible fully automated use of rigid sails or wings. This means no crew for a sail operatiom On board servo-controlled wings can provide savings on basic fuel, usually fossil fuel. Also, there is the possibility for less pollution emissions into the atmosphere. Because wind energy is free economic analysis considers investment in wings and minimal operational costs during exploitation. The basic techno-economical analysis is done on a windship concept and about 15% savings are reached.
