Abstract:

In both Asia and Europe, preconstruction primers (PCP) are routinely used and retained as an integral part of the coating system. The retention of PCPs can significantly reduce the painting cost of new ship builds. The cost of protective coatings (paint) application in new construction can be upwards of 10% of the total ship cost. The process is labor intensive; therefore, it is logical that most savings are derived from reducing labor steps. Retaining PCP eliminates the necessity of a second blast operation, thus reducing labor cost and hazardous waste disposal cost. This paper addresses the feasibility of retaining PCP as the permanent primer for protective coatings systems applied in such high-performance areas as exterior hull, underwater bottom, and most importantly ballast tanks. Should the retention of PCP be proven as a viable option, the process of coatings application can be improved resulting in significant cost savings. Spending of new construction dollars will not be necessary to remove the PCP prior to the application of high-performance coating and lining systems. The test program discussed in this paper was based on work sponsored by the National Shipbuilding Research Program Advanced Shipbuilding Enterprise (NSRPAES) and the US Navy. The Surface Preparation and Coatings Panel, SP3, of the Ship Production Committee formulated the program and provided direction during the course of the work. The Ship Production Committee is one of SNAME's nine technical and research committees, and consists of the chairman supported by the ship production major initiative panel chairs and selected others.
