THE EFFECT OF SPEED LOSS IN SERVICE ON SHIP FREIGHT INCOME AND FUEL ECONOMY

This paper presents a method to evaluate and improve service performance for a given ship. Resistance increase for a ship in sevice normally gives speed loss. A method that can evaluate the effect of this speed loss on freight income and fuel economy has been developed. The method developed includes use of dimensionless variables (in day/year) as an extension of the commonly used off-hire concept. Intervals for treatment of the wetted surface by docking or by other means can be calculated. The method should be able to give a good general impression of ship operating economy. The use of the extented off-hire concept reduces the number of variables, and will for example make sensitivity analyses much simpler.
