Advanced Education and Research on Marine Propulsion—New Method for Analyzing Propulsion Performance in Service

This paper describes how the most important subject of logistics is to make an effective transportation of cargo and people. Seafarers who are involved in sea-transportation take responsibility not only for safety of operations but also for economical and environmentally friendly operations. It is very important to grasp the knowledge of real-time ship propulsion performance on board in order to optimize operation and maintenance planning. Ship propulsion performance deteriorates in service because of the increase in the hull resistance and deterioration of the propeller performance caused by the adhesion of sessile organisms on its surface. However, only the relationship between the ship velocity and the shaft power can be directly detected on board. It is impossible to divide the propulsion performance into the influence of hull resistance and propeller performance by the conventional analysis method. In this paper, the authors, by carrying out model experiments in ship model basin and actual ship experiments on the Fukae-maru, which is installed with a shaft torque meter and a shaft thrust meter, have developed and proposed a new analyzing method, which by numerical calculations can estimate the in service hull resistance and the propeller performance individually. According to this proposed method of analyzing ship propulsion performance in service, the hull resistance performance and the propeller performance can be grasped individually; therefore, the prevailing surface condition of hull and propeller can be estimated correctly. The proposed method can be useful in making an effective maintenance plan and to achieve an economical and an environmentally friendly operation.
