抄録

To find out an optimum cycle of the ship bottom sweeping from the standpoint of service economics, an accurate increase in delivered horsepower due to the ship's bottom fouling was grasped and a statistical analysis was made referring to the deck logbook and the engineer's logbook in parallel with speed tests with actual vessels.<BR>Some findings are as follows: (1) Values measured in speed tests before and after docking under conditions of 6200 tonne dwt and a given speed revealed that the annual increase in delivered horsepower due to the ship bottom fouling would be about 1000PS. (2) Variations in a decade, taking the initial service as the original point, both in delivered horsepower and in fuel consumption was at between about 10 and 15% increase.
