Case Studies

This article presents a risk-based inspection (RBI) approach for the assessment of offshore subsea pipelines, accompanied by a practical case study.

Failure of internal attachment welds became a chronic issue for an NGL plant. Identifying design discrepancies was key to eliminating repeated failures.

A case study of insulation-drying technology that reduces the wetness time of thermal insulation and pipes.

The capabilities of automated radiographic testing (ART) make it the preferred method to manual techniques for detecting piping corrosion defects in the field.

A look into how complications due to low diameter, geometry, procedure, and qualification of welders resulted in flaws that were overlooked.

This article describes a storage tank built in a permafrost area and how FFS and FEA were used to address the challenges of foundation instability.

A review of the plan one site put in place to upgrade their performance from the fourth quartile to the first quartile and keep it there.

Common pitfalls in gathering inspection data using a case study where additional data gathering resulted in a significant improvement in FFS results.

A look at common reliability issues to help give perspective on where issues may be waiting and how to handle them when they arise.

Explore how more advanced modeling addresses the challenges of quantifying uncertainty and probability of failure to drive valuable inspections.

Local thin area (LTA) assessments rarely fail. It happens, but not often. Let’s look at examples of how significant an LTA can be and still pass an assessment.

Comprehension of the sulfidation corrosion reaction and the behavior of different materials in H2-free and H2/H2S environments is imperative for oil refineries.

Our proprietary furnace tube inspection system, FTIS is an ultrasonic inspection technology capable of rapid, automated fired heater coil inspection in refinery fired heaters. The data captured by our furnace tube inspection system is...

Can individual personnel be at fault for an incident? Is it an issue with the systems in place? Or does the assignment of blame come down to convenience?

This article concludes the series on microbial-induced corrosion by demonstrating the importance of microbe mitigation through two case studies.
