Premature failures of coatings applied to galvanized mast arms is not an unfamiliar problem. The properties of galvanizing that make it a difficult substrate to coat when new don’t simply disappear from beneath the original coating system.

This paper discusses the history of coatings maintenance on the Golden Gate Bridge and the modern maintenance process including bi-annual inspection, prioritizing, scheduling and execution. Several current projects including water jetting and suspender painting are also discussed.
This presentation will outline the results and conclusions of a number of years of testing and experience in surface preparation for high-performance coatings. Testing has shown that there are a number of important surface preparation variables that are not routinely monitored and controlled on coating projects. These variables will be identified and guidance will be provided on appropriate treatment to achieve coating results.
This paper considers the environmental and financial impact of various antifouling coatings for ships hulls. To do this comparison an eco-efficiency analysis was conducted comparing three different fouling control systems which offer the same customer benefit of a clean underwater hull. The results clearly demonstrated that fluoropolymer foul release technology can offer this benefit in the most eco efficient way having lower impacts on both the environment and on the economics of using that technology.
A life cycle costing analysis (LCCA) is the process of compiling cost estimates for each coating system option in combination with the expected life span of each of those options. In general terms, the lowest cost per year of service is the most economical choice. This LCCA process can be paired with an environmental impact analysis to evaluate the sustainability considerations of managing the water tank asset. One of the most commonly addressed factors in an environment life cycle assessment is a calculation of the greenhouse gas emissions associated with a process, presented in equivalent CO2 emissions.
The long term performance of any coating system will be limited by the ability of the applicator to achieve the best combination of surface preparation, application, and curing. In oil and gas facility construction, sometimes the most appropriate coating system is not the best available technology, but rather the system that ensures the highest probability for success based on the environmental conditions during application. An example is presented in which a zinc rich epoxy coating provides clear advantages over the specified inorganic zinc silicate due to circumstances specific to the particular application.
In recent years production of oil and gas from shale formations has multiplied and now contributes significantly to oil and gas supply. This type of unconventional production differs from historical conventional approaches with far reaching consequences for asset integrity management.The present paper outlines corrosion threats associated with shale development including acidizing fracing flowback CO2 and H2S in produced fluids and artificial lift. Usually little detailed information about corrosive exposure is available upfront. The production mode contributes to complex and highly variable environmental conditions. Corrosion cracking and weight loss corrosion of well completion materials are known to have occurred.Whereas classical asset integrity management is usually rolled out over many years the typical timescale in shale production ranges from just months to a few years driving low-cost quick earn-back scenarios. This paper discussed the consequences for materials selection and corrosion control.
Contractors often agree to deliver a project on a certain schedule. Then, once the work begins, the project suffers significant impacts, oftentimes through no fault of either the General Contractor or the Subcontractors, and then they do not have the tools in place to properly communicate the impacts, recover the losses and manage success.
Carbon capture and storage (CCS) or utilisation (CCU) of the captured carbon dioxide (CO2) are tools for reducing global carbon emissions, and to combat climate change both are required. According to the IEA1, in 2021, the global capacity of CCS grew by 48%i, showing that this technology is becoming more popular to meet sustainability targets.
Safe and stable operation of the process plant through its life cycle is an ultimate target of any integrity management system. Over the last decades, a number of possible ways and systems for managing plant integrity were described and implemented.1-4 A common path for all those efforts was to control and manage corrosion processes in a more-or-less systematic way by applying certain measures (monitoring techniques, material selection guidelines, operating procedures etc.) and performance indicators (remaining time-to-failure, inhibitor usage etc.). An effective corrosion and integrity management system, in theory, should be capable to “uncover” excessive corrosion incidents before serious damage occurs. Unfortunately, unexpected corrosion-related failures are still occurring in the petroleum industry.5 This situation stems predominantly from relatively poor data organization and management, leaving corrosion and key process information spread and hidden across different refinery functions and systems.
Coatings maintenance projects are typically scheduled and selected based on ASTM rust grade, service environment - corrosion rate, coating condition and project visibility or aesthetics. There is something missing. That something is a risk-based assessment. This paper will demonstrate how to make a risk grid and accommodate this into condition assessment criteria for prioritizing and scheduling painting projects.
