Army Regulation (AR) 11-42, Army Corrosion Prevention and Control Program, requires that program managers and engineers use a risk-based approach (RBA) to identify the corrosion susceptibility on critical components and the consequence to the overall system. Department of the Army Pamphlet (DA PAM) 11-42 provides an example of generic procedures for conducting a risk-based approach. The goal of this project was to develop a detailed, standardized process for conducting a risk-based approach during CPC planning.
Army Regulation 11-42, Army Corrosion Prevention and Control Program, requires that a risk-based approach be used to identify critical components, systems or infrastructure that are susceptible to corrosion. The corrosion degradation of these critical components can lead to the loss of capability or operability, a decrease in safety, an increased need for maintenance, or require special considerations in packaging, storage, and containerization. To aid in this task, a tool is in development to quantify the risk of corrosion occurring on a critical component during deployment. Risk can be calculated by identifying two factors: frequency and consequence. For this specific risk-based approach, frequency will be determined by calculating the corrosion susceptibility of a critical component by using environmentalseverity, operational hazards, design, preventive maintenance, and storage condition variables.Additionally, the impact of the critical component corroding will serve as the consequence in the calculation of risk by evaluating lifecycle cost and performance. Once frequency and consequence have been quantified the overall risk score can be calculated. If it is determined that the risk is unacceptable, mitigating actions can be taken to reduce risk. The mitigating actions are implemented, and the risk calculation is repeated until acceptable risk is determined. Using the risk-based approach duringacquisition to identify critical components most susceptible to corrosion, implementing design improvements and creating maintenance procedures prior to deployment, has the potential to reduce the lifecycle cost and increase readiness of the component.
In the recent years, Horizontal Directional Drilling - HDD - became a real improvement for pipeline construction when crossing obstacles such as rivers, roads or railways. For the corrosion protection of the carbon steel pipeline, a protective coating is associated with cathodic protection. But for trenchless techniques, the coating shall withstand the stresses from the installation. Several standards are used to specify corrosion protection coatings for buried pipelines but those documents do not cover the specific conditions of an HDD.

Atomic hydrogen can enter metallic microstructures from deposition processes like Cr plating or phosphatizing, chemical and electrochemical pickling treatments, during welding operations if the humidity of consumables is too high, by cathodic processes resulting from corrosion phenomena or contact with high pressure gaseous hydrogen. According to different chemical-physical mechanisms, atomic hydrogen can enter the metallic structure resulting in damages of various forms, such as HIC (hydrogen induced cracking), SOHIC (stress oriented HIC), delayed fracture and hydrogen embrittlement (HE).
It has become somewhat common in the oil and gas industry to convert producing wells containing 13Cr stainless steels to water injection wells. This practice has led to numerous tubing failures due to pitting of the 13Cr from oxygen dissolved in the injection water. The water source for these wells is often from produced water and seawater but other waters may also be injected.
