Abstract

This paper describes the experimental work on the drag characteristic of a tin-free Self Polishing Co-Polymer (SPC) with a Foul Release (FR) coating at the Marine Technology Centre, UTM. In this experiment a rotor apparatus has been used to measure drag of a coated aluminum cylinder. Various types of coating were investigated and the differential length technique was also applied to avoid the end effects during rotation. The measurements have been carried out using different cylinders, coated with both paint types and smooth surface. The experimental results shown that the frictional drag for the Foul Release test cylinders was lower than the tin-free SPC cylinders. According to the experiment, it has been found that the drag of an underwater hull coating was not depending only on the type of coatings which has been used on the hull surface but also that have been correlated with the speed of ship’s hull moving through the water.
