“…The rust formation due to corrosion depends on the environment and the type of material, as well. Carbon steels corrode mostly by general corrosion (uniform corrosion), but localized types of corrosion can also take place, e.g., pitting, which usually are not considered in conventional corrosion analysis [16]. Different reasons can be identified behind the growth of corrosion process in an offshore structure, such as temperature, salinity, pH, and coating damage due to tidal fluctuations, dissolved oxygen, variable cyclic load due to wave and wind impact, etc.…”

The ultrasound technique is a well-known non-destructive and efficient testing method for on-line corrosion monitoring. Wall thickness loss rate is the major parameter that defines the corrosion process in this approach. This paper presents a smart corrosion monitoring system for offshore wind turbines based on the ultrasound pulse-echo technique. The solution is first developed as an ultrasound testbed with the aim of upgrading it into a low-cost and low-power miniaturized system to be deployed inside offshore wind turbines. This paper discusses different important stages of the presented monitoring system as design methodology, the precision of the measurements, and system performance verification. The obtained results during the testing of a variety of samples show meaningful information about the thickness loss due to corrosion. Furthermore, the developed system allows us to measure the Time-of-Flight (ToF) with high precision on steel samples of different thicknesses and on coated steel samples using the offshore standard coating NORSOK 7A.

Corrosion is a widespread problem in metallic pipelines. Copious use of pipelines across many industries urges the application of inspection technologies for early detection of corrosion in order to prevent its costly and fatal outcomes. As of today, there is a range of ultrasonic techniques that cater to finding and sizing of the extent of corrosion. For piping inspection, guided wave (GW) modes are of interest for detecting corrosion defects as they offer rapid scanning over extended distances. Over the past three decades, the use of GWs have progressed tremendously and are commonplace today. More complex testing units have been fabricated because of recent advances in the fields of smart materials, electronics, and communication technologies. However, GW signals contain multiple modes and only a handful of them are used in inspection. This paper aims to provide an overview of current GW approaches focused on the detection, localization, and evaluation of corrosion defects in pipelines. The study presents a literature review of the main issues encountered in pipeline systems when using GWs and recent attempts to overcome the barriers.
