Objective:
This project was the final in a series of three NSRP projects that explored the performance of single coat systems over retained pre-construction primer (PCP) in laboratory and simulation tests as well as shipboard demonstrations. Initial testing showed that performance was acceptable for single coat materials applied over retained pre-construction primer after brush blasting or pressure washing. Based on the success of the laboratory and simulated ballast tank testing, Ingalls Shipbuilding requested (through the Navy-Industry working group) that Naval Sea Systems Command (NAVSEA) allow them to demonstrate the process on certain tanks and voids that present a low risk to the Navy. The project successfully demonstrated a process for retaining pre-construction primer on four prototype tanks during production of LPD-26. The production procedure used for the prototype tanks has been successfully used on 48 additional tanks on LPD-26 comprising over 83,000 square feet of coated surface.
