Bayesian Modeling Coating Performance

Picture for Bayesian Modeling Coating Performance

Coating degradation on Army ground systems represents a significant maintenance cost and effort. The objective of this proposed work is to develop a predictive model for coating degradation and subsequent substrate corrosion on Army ground assets. Provided with a better understanding of the root causes, steps can be taken to reduce corrosion impacts on Army materiel.

The research describes the effort to develop a predictive model for coating degradation and substrate corrosion on Army assets. The model incorporates the learning from field surveys of over 15,000 assets and 250,000 components; coating performance in standardized testing; and observations of coating condition as-applied to fielded items. The model outputs would provide a basis to (1) support a Commodity Manager to determine repaint intervals, optimizing expenditures and (2) develop new products / processes (impacting coating performance) increasing life of an asset protective coating system.

External corrosion on offshore O&G platforms is one of the biggest threats to asset integrity and its management is a large operational expense. Many operators now implement risk-based assessment (RBA) programs where all equipment is assessed periodically with the aim to reduce operational costs while maintaining integrity. Regulatory codes for offshore platforms in the GoM require a visual inspection of all pressure equipment and piping every five-years. In practice, this can equate to approximately 20% of equipment being inspected per year on a large-sized offshore platform (i.e., a topside weight of around 10,000 tons), with a rolling five-year inspection plan to balance the inspection workload evenly through time.

When it comes to a bridge structure with a serviceable Organic Zinc / Epoxy / Urethane (OZ/E/U) coating system, there is no golden answer on the most cost-effective maintenance painting strategy. Depending on the severity and amount of corrosion and coating breakdown on the structure, planned maintenance surface preparations range from spot power tool cleaning and spot painting to a full SSPC-SP 10 media blast and full recoating operation.

This paper details a precision process for removal of coatings and preparation of the metal surface underneath for optimal chemical adhesion without damaging the metal surface or the surface profile. A precision process is required for removal of coatings around corroded surfaces, potentially defective structures, or thin-walled ligaments where abrasive removal procedures will damage the substrate. In these cases, removing metal will worsen or cause a defect where replacement is expensive. A precision tool that can safely remove the coating, allow for inspection, and enhance adhesion for recoating is needed. This type of tool would enhance existing repair technologies and eliminate the immediate need for replacement.
