Impressed current cathodic protection (ICCP) for reinforced concrete structures has been installed on numerous bridges and wharves in Australia over the past 40 years. The exposure conditions at the majority of these bridges and wharves made them more susceptible to chloride-induced corrosion.

The ICCP systems in Australia are designed, installed and monitored in accordance with the global cathodic protection standards such as AMPP Standard SP 0290-2019, International Standard ISO 12696:2022, and Australian Standard AS 2832.5 – 2008 (R2018).

In oil refineries, one corrosion issue occurs each week worldwide that leads to a severe incident such as sudden leakages, e.g., resulting from pipe ruptures.^[1] These facts emphasize the need for corrosion control in refineries. Corrosion monitoring is one important approach to utilize and can maximize equipment integrity and productivity.

On March 2011 at Fukushima Daiichi NPS, seawater was injected into spent fuel pools just after the accident for emergency cooling. The temperature of the water in a pool raised up to 93 ℃, and the chloride ion concentration raised up to 1,944 ppm (maximum) after seawater injection. In this high temperature and high chloride ion concentration environment, localized corrosion including crevice corrosion may have occurred on components made of passive metals such as stainless steels. The environment is assumed to be susceptible to crevice corrosion for 304 SS based on laboratory experiments and the concept of ER, CREV. There is a low possibility of initiating localized corrosion after the water was purified and deoxygenated. However, it is not certain whether localized corrosion, once initiated and propagated under the severe condition, will repassivate after the bulk water is purified. It is necessary to examine the continuity of crevice corrosion propagation when the bulk water is purified and deaerated, which means the cathodic reactions outside the crevice will no longer contribute to the propagation of the corrosion.

This paper presents work in follow-up to the previous study. It is focused on UNS1 N07718, UNS N09925, UNS N07725 and UNS N09946. A series of incremental step load tests of compact tensile specimens were conducted to measure the fracture toughness during testing and cracking was monitored by the Electric Crack Growth Monitoring technique. A new engineering technique, referred to as statistical fractography, was used to investigate the fracture surface morphology and extract from it the fracture properties of the alloys.

Reservoir souring remains a challenging problem for the oil & gas industry, especially in aging assets where H2S and microorganisms from the reservoir can pose a serious risk to the integrity of producing wells and equipment. Nitrate treatment is commonly used to control SRB activity in the reservoir, but it is not always effective due to poor subsurface definition and increasing volumes required over time. In this study, we evaluated the use of a biocide to replace nitrate injection in reservoir conditions when nitrate is no longer effective to control SRB activity. We used sour, sand-packed reactors to evaluate a biocide formulation applied prior to and after nitrate cessation. Measurements of VFAs, nitrate, sulfide and genomic analysis were used to assess souring and changes in the microbial population. The results indicated that biocide was successful to remediate souring when applied before AND after the nitrate treatments. However, the cumulative amount of generated sulfide was higher when the biocide was applied after nitrate cessation, indicating the need of temporary co-injection of nitrate and biocide to prevent a H2S wave period. Genomic analysis indicated that this formulation specifically targeted the SRB rather than broadly killing the microbial population. Taken together, this study highlights a new strategy to control reservoir souring and potential corrosion issues in producing wells.

This paper provides a real case study in regard to controlling the welding repair rate and NDT backlog in a company mega-project assigned to a new contractor. This case study shows the improvements in both KPIs, through the utilization of various quality and improvement tools, such as root cause analysis (Fishbone and Pareto chart), brainstorming, and PDCA cycle. The collaborative efforts between the client and contractor, including the welding and NDT subcontractors, resulted in reducing the WRR from 11.04% to below 5% (the set KPI). The NDT backlog was also controlled and reduced from 2500 joints to below 600 joints (less than one week production).

Controlling AC Safety And Corrosion Risks on Pipelines with Digital Twins

Product Number: MECC23-20075-SG

Author: Christophe Baete

Publication Date: 2023

According NACE21414 and ISO18086 standards AC corrosion risks on pipelines requires knowledge on the AC and CP current density on a coating defect or coupon. The induced voltage is mainly a result of the pipeline coating properties, connections to grounded structures (anode beds, other pipelines, AC grounding systems, etc.) and the powerline characteristics (AC load, phase arrangement, tower configuration, etc.). A proper mitigation design engineering study should include all these variables.

As governments around the world seek to promote the adoption of lower-carbon fuels, credits are available for fuels which satisfy various low-carbon or renewable fuels standards. In the United States, the most common standards discussed include California’s Low Carbon Fuels Standard1 and the US EPA’s Renewable Fuel Standard2. These standards define the acceptable methods (called pathways) for conversion of renewable feeds into consumer fuel products. In order for a producer to be eligible for credits, one of the acceptable pathways must be used. The most common pathway presently being used or considered by most facilities is hydrotreating.

Pipelines are one of the essential elements in the upstream oil and gas operation network. Transportation of the produced products to the end client is ensured through maintaining the pipeline integrity. Internal corrosion is one of the major problems that could directly affect pipeline integrity and, in severe cases, lead to failure. Different internal corrosion monitoring techniques are available to assess and evaluate fluid corrosivity and monitor it. Online Corrosion Monitoring (OCM) that uses corrosion coupons are widely utilized to measure the corrosion and pitting rate, in addition to fluid and bacteria analysis for fluid sample collected from cleaning pigging processes that qualitatively and quantitatively reflect the fluid corrosivity. Inline inspection (ILI) is a very sophisticated non-destructive inspection technique conducted for identifying pitting corrosion, erosion, cracks, and other types of pipeline defects. This paper presents a case study on correlates the Online Corrosion Monitoring (OCM) data, Wet chemistry analysis of the fluid, cleaning pigging samples, operational Data along with Inline inspection (ILI) data for one of the main and critical North Kuwait crude export pipeline. The paper's outcome could be utilized for implementing a good corrosion mitigation plan and prioritizing and following up on the action plans of the Crude pipelines.
