The paper is an overview of the National Shipbuilding Research Program (NSRP) Surface Preparation and Coating Panel’s (SP&C) mission to reduce the cost of construction, maintenance, and repair of US Navy ships. The Panel’s “Specs to Decks” approach; research, evaluate, develop, and sustain current and emerging technologies that will reduce cost and maintain or enhance quality, serves as a rudder that guides the Panel’s performance. This review will provide a summary of the Panel and a look at some of its implemented, current, and proposed projects.

This review will provide a summary of the Panel and a look at some of its implemented, current, and proposed projects. The utilization of Retention of Pre-Construction Primer (PCP) and Robust Paperless Paint (Phase I) will allow Shipyards to reduce the cost of coating ships and improve the documentation of work done during the coatings process. Robust Paperless Paint (Phase II) and the utilization of the Latest Digital Inspection Tools will ensure that Shipyards and their Crafts Workers have the tools needed to meet requirements, while enhancing the coatings process by reducing human intervention and/or errors. The proposed projects: Implementation of Robust Functional Paperless Paint, Cleaning Polysiloxane Topside Coatings, Visual Work Instructions for Coatings, and Boomlift Carried Environmental Enclosure will further enable the NSRP’s Shipyards (see Figure 1 below) by continuing to improve their processes and overall performance, while sharing lessons learned and best practices. The focus of these efforts are to reduce the cost of shipbuilding while maintaining quality.
A device measuring solution resistance across a gold interdigitated electrode, surface temperature and relative humidity, dynamically monitors environmental parameters on board a naval ship over the period of 9 months. Rigorous statistical analysis is used to analyze solution resistance data.

Fluorourethane coatings based on FEVE, fluoroethylene vinyl ether chemistry, have been used globally for over 30 years. This technology has a proven record of outstanding performance against exposure to the elements and has been used in applications ranging from aerospace to architectural structures. Recently, the bridge market has taken notice of this high performance, especially in harsh marine environments. Resistance to degradation by UV light is important to the longevity of a bridge structure, but it could be argued that corrosion resistance is the key performance indicator for a protective topcoat.
The United States Army and Marine Corps (USMC) paint their vehicles with the Chemical Agent Resistant Coating (CARC) system. This system consists of a pretreatment, an epoxy primer, and polyurethane topcoat, similar to many other industrial paint systems, but with added functional requirements (e.g., chemical agent resistance, camouflage, and signature reduction) unique to these paints. The systems that utilize these coatings are also designed for specific capabilities, of which corrosion is usually a lower priority. Lastly, the vehicles and equipment of the Army and USMC typically operate in harsh environments, which are highly corrosive.
