This guide provides the specifier and user with information regarding the use of pre-construction primers (PCPs) on structural steel in shipbuilding. It provides background on the reasons to use and retain PCPs, the types of PCPs and their application and inspection, and the secondary surface preparation processes that are used when PCPs are retained in the final, compatible primary coating system. While this document contains details specific to the shipbuilding industry, the technical concepts related to the application and retention of PCP may apply to other industrial applications.

This paper will provide information on current SSPC training and certification programs related to industry standards and practical aspects of selecting, specifying, and using coatings safely, effectively and economically to protect structures in harsh marine environments.
Cleaning, coating, and the nondestructive testing (NDT) of corrosion-susceptible surfaces requires extensive manual labor, often at vertical heights that create a dangerous occupational environment. Drones, also known as unmanned aerial systems (UAS), unmanned aerial vehicles (UAV), or small unmanned aerial vehicles (sUAV) can be leveraged to perform some of these tasks, including cleaning and coating, while keeping workers safely on the ground.
Water electrolysis is a process that uses electricity, potentially from renewable energy sources, to split water into hydrogen and oxygen. Among water electrolysis technologies, alkaline electrolysis is the most developed and commercially available, but PEM electrolysis is emerging as a more efficient solution. It presents several advantages, such as the possibility to operate at high pressure and high current density for production of hydrogen.
The Florida Department of Transportation (FDOT) spends over $50 million in steel bridge fabrication and shop painting annually. According to a recent Federal Highway Administration (FHWA) sponsored study by Appleman, approximately 7% of the cost of a steel bridge is budgeted for blast cleaning and primer application in most shops. FDOT knows that proper surface preparation and primer application are the best ways to assure long-term corrosion protection.
NEPCOAT (Northeast Protective Coating Committee) developed an innovative approach for streamlining coating material testing and selection on a regional basis. Following their success, AASHTO took the concept nationwide within their NTPEP program.
Saudi Aramco coating standards have been holding a great status of prestige, not only in the Arabian Gulf area, but all around the world. Due to the size and significance of Saudi Aramco as one of the largest oil-and-gas producers in the world, the coating applications for its facilities had to follow suit. Yet, the coating standards were also interconnected with the coating industry, its limitations and old practices.
This paper will cover understanding the hot-dip galvanizing process and coating benefits, Identify the benefits of utilizing paint/powder coating with hot-dip galvanizing in a duplex system, Recognize the importance of communication and clear assignments of responsibility in the specification of successful duplex systems and differentiate between HDG surface conditions in order to properly prepare the zinc coating for paint/powder.
This visual comparator is used with the latest version of NACE SP0178 (sold separately), mentioned in Appendix C, to determine whether welds are suitable for coating. This durable T Grade ABS plastic weld replica is molded from actual welds and includes 14 welds for comparison of various degrees of surface finishing (full-seam welds, skip welds, butt welds, lap welds, and others). Use of this visual aid will facilitate weld inspection by the end user.
Organic coatings protect the underlying metallic substrate against corrosion by acting as a barrier to corrosive species such as water, ions, and oxygen. Unfortunately, coatings might contain defects and could degrade or disbond under some environmental conditions, resulting in favorable pathways for such corrosive species.
Barrier protection is one of the modes by which intact coatings provide protection to metal substrates through a reduction of the transport of materials, ions, or charge.
This discussion will review case studies from several bridge access projects where suspended scaffolding was used to provide safe, economical access for crews performing inspection, structural repair, demolition, blasting and coating work. Special attention will be paid to advanced project planning, worker safety requirements, unique platform configurations and productivity improving tips.
