The NACE International Institute Contractor Accreditation Program (NIICAP) is an industry managed accreditation program that validates a contractor's quality assurance program, support practices, and production processes.
SSPC established the Coating Application Specialist (CAS) Certification Program for industrial painters in 2008, at present there are 8 standards for applicators. It includes QP1 FIELD APPLICATION TO COMPLEX INDUSTRIAL AND MARINE STRUCTURES, QP2 FIELD REMOVAL OF HAZARDOUS COATINGS and QP3 SHOP PAINTING ACCREDITATION PROGRAM.

NEPCOAT stands for the Northeast Protective Coating Committee and is comprised of tenmember Departments of Transportation, from Connecticut, Delaware, Massachusetts, Maine,New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont. NEPCOATwas founded in 1992 and has for thirty years evaluated and qualified paint systems for use onbridges, both for shop-applied new steel, and field-applied totally cleaned existing steel.
One of the most important and overlooked aspects of the coating project is the documentation of events and conditions as they occur. This paper will discuss the importance of documentation as well as new methods of accomplishing this and other tasks using new wireless technology.
A new and innovative method has been developed to allow for cathodic protection of the upper / new tank bottom in a double bottom tank. When two steel tank bottoms are in electrical contact with each other the lower tank bottom acts as an electrical shield to cathodic protection (CP) current external from the tank. By electrically isolating the new / upper tank bottom from the old tank bottom and old dead shell CP current can then flow right through the old tank bottom to cathodically protect the upper / new tank bottom. The old tank bottom and dead shell become essentially transparent. Non-conductive type release prevention membranes were required to be used in the past between the old tank bottom and upper / new tank bottom to prevent the galvanic affects of new steel / old steel corrosion. A conductive type of release prevention barrier can now be utuilized to provide leak prevention without the concern of new steel /old steel galvanic corrosion occuring between the two tank bottoms. Significant advantages occur by electrically isolating the upper / new tank bottom away from the old tank bottom and dead shell of which the most significant is that CP current can always pass through the old tank bottom eliminating the problems and concerns of consumed CP systems between the tank bottoms. Cathodic Protection data from two tanks incorporating this new and innovative method will be discussed.
The next generation of aliphatic moisture cure urethane (MCU) topcoats has been developed through new resin development and advancements in MCU formulation knowledge. These new MCU coatings drastically improve upon current commercial aliphatic MCU topcoats, which are typically applied between 2-3 mils DFT.
When it comes to roofing, after the expected service life of individual products, the most common attribute that is used to describe the performance is often the solar reflectivity. Solar reflectivity is the percentage of solar energy that is reflected from the roof surface instead of being absorbed into the roof and building as a whole.
Metallizing in NH was a coating used only sparingly in the past at critical locations on two major bridges. Its greater use was severely limited by the lack of qualified applicators, absence from bridge fabricator operations, and overall excessive cost. This picture changed dramatically with the impetus of the new metallized Memorial Bridge project and the massive investment in metallizing equipment at a large local bridge fabricator that made metallizing possible for this bridge. The successful use and ten-year performance of the thermal spray coating (TSC), i.e. metallizing, on this bridge has had a significant impact on metallized New England bridges tofollow.
Time-tested and proven methods to control corrosion of oil and gas industry infrastructures (pipelines, facilities, and refineries) include the use of appropriate materials, protective coatings, cathodic protection (CP), and corrosion inhibitors.
Criteria for evaluation, qualification, and selection of materials, coatings and application of CP arequantitative and are typically followed rigorously (Table 1). Standards on these quantitative criteria are established, and in many cases have been adopted by regulatory authorities.
