Case Studies for using Advanced NDT in Oil & Gas Industries
Non-destructive Testing (NDT) consists of a variety of non-invasive inspection techniques used commonly for mechanical equipment, structures, and piping systems to locate and determine the defect features such as size, shape, and orientation.
In this article, we tried to collect different cases and provide summary status of technique used by worldwide companies.
Corrosion protection of cargo oil tanks of crude oil tankers
Crude oil is a complex mixture of substances at varying ratios and in most cases contains at least some salt water. Even after desalination some of this brine remains dissolved in the crude and gradually sinks to the bottom of the cargo oil tank during transport. The corrosive nature of salt, along with microorganisms and other aggressive substances contained in the cargo oil, causes rust, most notably in the form of pitting, which are cavities in the steel that deepen over time.
