Case Histories

Researchers Use Machine Learning to Detect Pitting Corrosion

In their 2024 AMPP paper, these authors proposed a technique for early-stage pitting detection through machine learning. Pitting is a localized form of corrosion that can cause cavities and structural failure in metallic materials, and it can be challenging to detect and prevent.

Never Again: An Inspection of a Water Tower

After finding a water leak from its holding tank, the owner/operator of a town water tower reached out to Total Access Solutions Co. (TASC) to request an inspection. One TASC got on site, investigators were able to deduce more information about the potential cause(s) of the premature failure.

Condition Assessment of Aging Concrete Structures: Part 1

This two-part article reviews the corrosion risk assessment, structural considerations, and engineering solutions for the steel-reinforced structural elements of an aging concrete building. This building had exhibited accelerated corrosion in corrosive environments.

Engineers Plumb the Depths to Retrofit Offshore Platforms

Safety, cost savings, and environmental protection were the leading priorities when a team at Deepwater Corrosion Services set out to retrofit three of the world’s deepest oil and gas platforms off the California coast.

Cold-Bonding Technology Restores Thailand Petroleum Pipeline

Utilizing unique cold-bonding technology, a large-scale pipeline restoration project was recently completed in Thailand. Based on a solvent-free epoxy resin reinforced with silicon steel alloy, the two-part repair composite is designed for metal repair and resurfacing projects.

Never Again: Dealing With the CUI Phenomenon

In this case study, significant corrosion was observed on lines supplying air handling units and swimming pools at a Dubai hotel. According to the client, the chilled water application system was installed three years prior and initially handled by a maintenance contractor before being handed over to the asset owner.

Corrosion Prevention in the Cruise Ship Industry

While the battle against corrosion in maritime settings is largely similar, cruise ships do pose some extra challenges. Outfittings such as swimming pools and even lifeboats need to be treated, as even the aesthetics of rust and wear will have an impact on the impression the boat’s condition makes on passengers.

NIST Updates Investigation of Champlain Towers Collapse

In a recent National Construction Safety Team (NCST) Advisory Committee meeting, National Institute of Standards and Technology (NIST) investigators shared details of their investigation into the partial collapse of the Champlain Towers South building in Surfside, Florida, USA.

Flexible Approach Restores Texas Water Pump Station

When Corrosion Control Resources, Inc. refurbished a water pump station near Dallas, they initially expected to hand blast with coal slag before applying new coatings. However, they changed course after unexpectedly finding the pipe to be lined with coal tar enamel.

Air Force Trials New Corrosion Control Plan at Guam Base

At the U.S. Andersen Air Force Base in Guam, the equipment maintenance team is employing a new method of limiting corrosion and extending service life on trailers by switching from stainless steel to copper-nickel alloy brake lines.

Interview: How Coatings Inspection Needs Are Evolving

Michael Beamish, vice president and general manager at DeFelsko Corp., shares feedback he’s heard from coatings inspectors about their challenges in the field. In 2023, many of these needs revolve around increasing speed and reporting efficiency.

Advances in Protecting Pipelines from Hurricane Damage

With the Northern Hemisphere’s 2023 hurricane season in full swing and nearing its annual peak, emerging technologies and artificial intelligence are among new tools offering hope for superior pipeline protection against mighty storms.

Multistage Commissioning and Concurrent Survey Work on a New Pipeline

On a new pipeline in southeast Texas, this multiphase corrosion control project encompassed the design of cathodic protection and induced alternating current (AC) mitigation systems, followed by subsequent installation, commissioning, and post-construction survey work.

Newly Approved Epoxy Solution Protects Texas Water Tank

Maguire Iron partnered with Sherwin-Williams to recoat the interior of an elevated water storage tank in Hitchcock, Texas, USA. The project was the first time in which the newly NSF 61/600-approved Sherplate 600 potable water epoxy coating was applied since its approval for tanks.

U.S. Engineers Address Pump Corrosion for Hurricane Season

The New Orleans district of the U.S. Army Corps of Engineers is partnering with the U.S. Navy’s salvage and diving supervisor to evaluate corrosion damage as part of a plan to ensure sufficient pumping capacity is available during a tropical weather event.
