The typical operating cycles of coke drums create thermal stresses that eventually lead to fatigue cracks called ‘elephant skin’ (ES) in both the inside diameter (ID) and outside diameter (OD) of coke drums. Traditionally, these have been inspected through a multi-stage process from initial dye penetrant inspection, visual assessment of ES crack depth, baseline ultrasonic thickness (UT) gauging, exploratory grinding to chase crack tip/s of select locations, confirmatory dye penetrant inspection, and UT gauging to determine the remaining wall thickness, to calculate the crack depth. This traditional process is not only slow and a time-consuming chain of activities, but also leads to subjectivity in the crack depth assessment, and a challenge to coordinate different groups in a turn-around. An Eddy Current Array (ECA) inspection crawler was designed and built to solve these issues.

Many assets utilized for the processing, storage, and transportation of products are owned by companies operating in the petrochemical sector. Components such as pipelines, pressure vessels, and aboveground storage tanks (AST) are examples of assets. Because of their complexity and the number of components they include, these assets need to be inspected and subjected to nondestructive testing (NDT) at regular intervals.

Geothermal energy is an excellent source of renewable clean power generation, as well as for heating and cooling. Unlike other renewable energy sources, it is unaffected by local climate conditions. However, the heat exchangers used in geothermal power plants are under constant threat of scale formation and corrosion due to the harsh operational conditions to which they are exposed. Therefore, surface modifications to heat exchanger materials, for example through coatings, are necessary to improving the efficiency and durability of geothermal plant.v

This study introduces a modulated Impressed Current Cathodic Protection (ICCP) system, specifically designed for Oil & Gas subsea production structures. Unlike traditional Sacrificial Anode Cathodic Protection (SACP) systems, which provide a constant output, the prototype operates on a closed-loop feedback system to dynamically control cathodic potentials within a specified voltage range. This allows for adjustments to varying environmental conditions, such as seawater temperature and microbial activity. The paper outlines the design, development, and testing of this innovative ICCP system and offers a comparative evaluation with existing SACP methods. In doing so, it addresses some of the limitations of current SACP systems, including issues like hydrogen embrittlement and premature anode depletion. The goal is to demonstrate the enhanced effectiveness and sustainability of the proposed ICCP system in subsea corrosion protection. Future work aims to integrate a patented predictive modeling feedback mechanism to further optimize the system's adaptability.

In the oil and gas industry, solid metal equipment such as pipelines, pressure vessels, heat exchangers and valves are susceptible to surface cracks and discontinuities attributed to cyclic loading, process environment and severe operating conditions. These anomalies affect the safety, structural functionality, reliability, integrity and life cycle of the equipment. They could lead to catastrophic incidents if not detected timely, evaluated, monitored and properly repaired.

In this work, two comprehensive mechanistic models of aqueous carbon dioxide (CO2) corrosion produced by Nordsveen et al.1 and Kahyarian et al.2 17 years apart are recreated and compared to highlight the evolution in understanding. The differences between the models include the role of carbonic acid at the surface, whether it is directly reduced or acts as a buffering agent, as well as different mechanisms for the anodic response, and varying temperature responses of multiple input variables. Through recreation and validation of these models using the same software, key comparisons are made to understand the effect of these changes on predicted corrosion rate, surface pH, and speciation through the boundary layers. These values are plotted across a range of input parameters to investigate how the change in scientific understanding influences predictive response of corrosion models.

The Brazilian cost of corrosion was estimated at 3% of the GPD in 2018, that percentage is equivalent to approximately $US 49 billion, according to an ABRACO⁽¹⁾ journal released in 2020.¹ It is estimated that from this cost $US 19 billion could have been saved through anticorrosive actions. In another research conducted by the EPRI⁽²⁾ the results showed that at least 22% of corrosion costs could be avoided through adequate mitigating actions.²

Corrosion of aircraft costs the U.S. Department of Defense (DoD) billions of dollars annually, increases demand on labor, degrades operational readiness, and is a safety issue. Coatings are the most effective means of protection from corrosion, but with time, mechanical and environmental stresses will degrade and eventually breach the coating. For a pristine structure, the coating system reacts primarily to dynamic moisture, temperature, and mechanical loads that can vary over multiple time scales.

Aesthetic Issues With Spray-Applied Fluoropolymer Coating System

Product Number: 51322-17971-SG

A building, partially clad in fluoropolymer coated aluminum panels, was observed to have an aesthetically unacceptable appearance while still under construction. Once installed on the building, many of the panels exhibited a vertical streaked appearance under certain conditions. When the panels were at ground level, or when the sun was bright, the streaky appearance was not noticeable. However, in conditions of low light, such as during early morning, dusk, or on cloudy days the streaky appearance was reported to become apparent. A visual mock-up, consisting of multiple coated panels that had been approved by the architect as a guide to the anticipated appearance were also present on-site as a reference. This visual mock-up was used as a reference for acceptable appearance of the coated panels.

In recent decade, the applications of DSS have significantly increased in oil & gas industry, due to their attractive properties compared to austenitic grades with similar corrosion resistance. The DSS products exhibit a better resistance to pitting, stress corrosion cracking and higher mechanical properties compared to other austenitic stainless steel grades. The microstructure of these materials consists of approximately 50% austenite (γ) and 50% ferrite (α) phases, obtained by means of a solution heat treatment.
