New Zealand’s Transport Accident Investigation Commission published its final report on a fatal accident involving the massive Emerald Princess cruise vessel, in which a nitrogen cylinder burst and fatally injured a nearby crew member.
The City of San Francisco needed to determine the condition of offshore pipelines and their support structures and whether they were fit to continue operating, needed repairs or replacements, or required coating or lining repair.
According to U.S. researchers, a localized form of nanoscale corrosion appears responsible for unpredictably decreasing the working life of steel pipes used frequently in the oil and gas industry.
Funded by the European Commission, this new project involves the design of a portable, three-dimensional ultrasonic scanner for the nondestructive testing and evaluation of concrete in bridges and other building structures.
Independent investigators found extensive corrosion on the well casing that broke open at Southern California Gas Co.'s Aliso Canyon gas storage facility in October 2015. In the aftermath, engineering consultancy Blade Energy Partners was granted authority by the California Public Utilities Commission (CPUC) to conduct a root cause analysis of the metallurgical and fractographic aspects of the gas leak.
Divers conducting inspections of the Mickler-O’Connell Bridge detected heavy corrosion of the steel H-piles. Researchers suspect microbiologically influenced corrosion caused localized degradation.
Researchers with the Southwest Research Institute conducted experiments to evaluate the presence of microbiologically influenced corrosion under high and low relative humidity conditions when storing spent nuclear fuel in dry storage systems.
A recent study from European university scientists suggests that samples of reinforced concrete need to be larger to ensure accuracy in corrosion detection.
An engineering study reports significant corrosion, due to poor coating selection and application, that led to structural damage in many locations at a major college football stadium in Florida.
Led by university researchers, the findings of this new study support the understanding that lead leached into the pipes system in Flint, Michigan, because the water wasn’t treated to prevent corrosion.
New x-ray diffraction technologies are enabling corrosion analysis to be carried out much more quickly and thoroughly by using a portable unit in the field.
The new containment structure, moved into position in November 2016, includes a ventilation system that developers say will help ensure there is no need to replace the coating used to control corrosion.
The U.S. congressional committee investigating the water crisis in Flint, Michigan issued final letters citing failures at all levels of government, including problems at both the Michigan Department of Environmental Quality and the U.S. Environmental Protection Agency.
Although methods for managing internal corrosion are well established, many pipelines operators experience repeated internal corrosion incidents, suggesting opportunities likely exist for continuous improvement.
One of the most common drivers of concrete repairs is corrosion of the concrete’s steel reinforcement, often caused by chloride ions in the environment entering the concrete and eventually reaching the embedded steel.
