COATINGS AND COSTS

Where ships' hull coating is concerned there are two schools of thought: the straightforward acceptance of paint consumption as a cost that obviously must be controlled, and the incentive to look for new advances in coating technology as a means of saving other costs, notably fuel costs by keeping hull roughness to a minimum. Mention is made of the work of the British Ship Research Association in this field. A recent BSRA publication state that research has shown that an analysis which expresses the mean height of peak-to-valley roughness of the hull surface profile in units of microns per 50 mm length is suited to the correlation of ship resistance with hull roughness. It can be assumed that an increase of 1% in engine power is usually required to maintain the same ship speed for each 10 mu m/50 mm increase in roughness. A well painted and maintained ship can be expected to deteriorate at not more than 25 mu m/50 mm per annum. The scope of the BSRA research and details of the service which the Association can offer are described. A number of major coatings manufacturers are mentioned and the range and characteristics of their individual products discussed. Order from: BSRA as No. 47,567.
