For application of high-performance coating in a new shipbuilding, the abrasive blasting cleaning is widely favored primarily because of its economic and performance benefits. Blasting cleaning productivity is known to be affected by a number of parameters, such as air pressure at the nozzle, air volume, abrasive/air mixing ratio, abrasive type and size, and type of nozzle used, and so on. To achieve the economic benefits from abrasive blasting, proper selection and matching of these parameters are essential. In this study, a quantitative relationship between blastingrelated operation parameters and blasting efficiency is evaluated, and the optimum blasting conditions are sought, which can dramatically improve the blasting productivity as well as effectively meet new IMO’s PSPC surface preparation requirements. The results clearly indicated that the newly optimized blasting condition can remarkably reduce the amount of abrasive used. Adjusting the profile height by careful selection of the primary variables such as abrasive size and nozzle pressure, which are closely related to the surface roughness, is important in meeting the new IMO standard.
