Abstract

Using the HFO on board merchant ships has an advantage in terms of voyage expenses where fuel costs have an important role. However, there are special circumstances in which the use of MDO becomes necessity and leads to the increased total costs. Such circumstances are recognized on the example of two ships of the same owner who operate in the system of one Pool , and that the Pool's normative tables are shown only through the use of HFO. In this way the result of the differences in costs that would be prescribed by the rules of the participants, should be charged only to the owner.
Taking into account the information found in available sources, the main characteristics of the machines in which the fuel burns on board both the ships were pointed out in relation to the usage of MDO and to the changing over from HFO to MDO (and vice versa), and thus highlighted the special circumstances for each of them, laying the foundation for the adoption of the concluding positions.
After analyzing all available data, and examining the professional literature a uniquely synthesized definition for the specified case is given.
Conclusive result is explained the difference in accordance with the manufacturer's instructions and operating conditions of ships, which is made a precondition of accepting the necessity of recognition of these increased costs by Pool.
