A comparison of conventional and airless abrasive blasting techniques used to prepare steel surfaces (e.g., North Sea oil facilities, offshore structures, e.g., storage tanks, and land-based oil terminals) for corrosion protection shows the advantages of the Autoblast automatic abrasive blasting machine over the conventional air-blasting machine. Autoblast is based on the principle of a paddle type wheel, revolving at high speed, being continuously fed with abrasive, which is propelled off the wheel onto the work surface by centrifugal force in such a manner and at such an angle that the abrasive is reclaimed, cleaned and returned to the wheel for reuse. All this is done within a totally enclosed, self-propelled, highly maneuverable vehicle. The machine also incorporates a separator to remove dust and refuse, which is passed through a dust collector to allow the machine to operate 98% free of pollution. The production rate of Autoblast machines varies from about 20 sq m/man-hour on offshore platforms with confined areas, to 80 sq m/man-hour on newly constructed storage tanks.
