摘要：The objective of this paper is to describe and evaluate the scheme of the structure of ship’s voyage cost for determining optimum ship’s capacity. The problems in designing optimum ship’s capacity appear due to the numerous considerations that must be taken into account. Some of these considerations are the shipowner’s costs on the concerned route, which must be quantified in order to apply optimization of ship’s capacity. Generally shipowner’s costs on the considered voyage can be presented as the daily cost at sea, the daily cost in port, and the commonly operating cost. The main goal of this research is to define daily cost at sea. The structure of daily cost at sea from the shipowner’s point of view in this paper generally might be described as cost basis on cargo units hauling, fuel cost, an channel dues. Syntheses of the mentioned costs at port are graphically transformed to a cost per unit of ship’s capacity at sea.
