ABSTRACT
Around the world, there is an increasing interest in how to reduce the negative impact of ships mooring in ports on the environment. It is necessary to find new solutions of this problem. One of them can be use of an autonomous electricity generating system on ships with photovoltaic cells. The main source of air pollutants emission by ships mooring in ports are marine generating sets. The generators are driven by marine diesel engines called auxiliary engines. Shut down of marine generating sets and change of electricity source for photovoltaic cells panels leads to reduction of air pollutants emission. It is important to estimate the electric power demand by ships mooring in ports and calculate the area of photovoltaic cells panels using solar energy. The specificity of cargo ship construction, first of all bulk-carriers, allows to install on cargo-hold covers large area of photovoltaic cells panels. The main technical problem in that case deals with storage of electric energy generated by photovoltaic cells panels and conversion of the energy. The authors propose the solution that can lead to design of whole system and significant reduction of air pollutants emission by ships mooring in ports.
