This summary is a look at implementable work and a gage of the value of future work. The strategic implementation of Surface Preparation and Coatings Automation, Standardization and Digitization of Visual Inspection, and Surface Preparation and Coatings Training Certification Program could provide cost and schedule savings. Optimizing Power Tool Surface Preparation potentially will increase Shipbuilders safety, while reducing material and labor costs.
NSRP SP&C Panel’s mission is to reduce coatings cost of Navy ships. The Panel’s Specifications to Deck-Plate Application approach; research, evaluate, develop, and sustain current and emerging technologies, enables this effort to reduce cost and maintain / enhance quality of coatings and corrosion control of Naval and commercial ships.This summary is a look at implementable work and a gage of the value of future work. The strategic implementation of Surface Preparation and Coatings Automation, Standardization and Digitization of Visual Inspection, and Surface Preparation and Coatings Training Certification Program could provide cost and schedule savings. Optimizing Power Tool Surface Preparation potentially will increase Shipbuilders safety, while reducing material and labor costs.The Panel is a collaboration of SP&C professionals from Shipyards, Industry, Coatings Manufacturers, Subcontractors, Academia, and NAVSEA. NAVSEA’s involvement includes the SP&C Technical Warrant Holder (TWH). The Panel’s partnership with NAVSEA provide a vehicle for sharing ideas, addressing issues, and implementing research and development outcomes. These efforts; technical data, implementation guidelines, procedures, cost savings ideas, and specification clarification / revisions are presented to NAVSEA. Projects outcomes are submitted to SSRAC annually for review, consideration, and acceptance relative to 009.32.The Panel is open to the public and can be accessed on line at www.nsrp.org. Meetings information and presentations are posted / will be made available through this site.LEARNING OBJECTIVES:• Demonstrate the implementation of effective work practices on the deck plate through solid research• Describe the benefits of a solid working relationship with NAVSEA SP&C Technical Warrant Holder (TWH)• Discuss the benefits of a collaborative relationship across the greater Coatings Community• Discuss the mitigation of Shipbuilding cost during construction, maintenance, and repairs
The role of a Coating Inspector has evolved considerably over the past few decades, and the responsibilities have increased over what used to be a rather straightforward job: to verify that surface preparation and coating application meet the project specification requirements. Today there are week-long or multi-week basic and advanced coating inspection courses, specialty courses that are industry-specific (e.g., bridge, nuclear), courses that are substrate-specific (e.g., concrete coatings inspection) and even coating-specific (e.g., inspection of thermal spray coatings).

Power tool cleaning has been a common method of surface preparation prior to coating application since the dawn of steel shipbuilding. Power tools are usually handheld pneumatic, or sometimes electric, devices that through impacting or abrasive action can remove coating and corrosion. Most commonly power tool cleaning has been used for re-work or coating repair associated with outfitting. Typically, power tools are limited to the touch up or repair of small areas or areas that cannot be accessed by bulkier equipment such as abrasive blasters.
A steel surface has been properly prepared to a white metal blast and it looks great … to the naked eye at least. But is it? Why is a surface that has the correct profile and appears to be perfectly clean typically not good enough? A standard abrasive blast will give you the profile and visible cleanliness, but how clean is it? Testing is the only way to determine. That is testing for conductivity, chlorides, and any other contaminants.
