Sažetak
In this work a rigid sail (wing) is considered as additional ship propulsion as well as electric motor propulsion powered by a photovoltaics. Additional ship propulsion by sails is well known and used (traditional wind ship). Modern ships can use rigid sails or wings for main propulsion or additional - wind-assisted propulsion for ships. Present material and control technologies makes possible fully automated use of the wings. This means no crew for the sail operation. On board servo-controlled wings can provide savings on basic energy source for the main propulsion (fossil fuel or electric). As addition, there is also possibility to put the photovoltaics on the ship surfaces exposed to the sunlight. Thus converted solar energy gives the electric power. Both wings and photovoltaics can make a hybrid wind-solar power source. Ship powered by a hybrid wind-solar power source should be considered as a low-emission vehicle or even as a zero-emission vehicle. Because wind and solar energy are free, economic analysis considers investment in the hybrid system with minimal operational costs during exploitation. This work describes possible use of the hybrid wind-solar power source and gives results of simulation on several ferry lines along the Adriatic coast. The basic techno- economical analysis is done on a solar-wind ship concept and more than 30% main fuel savings are reached on yearly basis.
