Heat Exchanger Failure Case Study - Understanding the Total Cost of a Corrosion Issue in the Oil & Gas Industry

The total cost of corrosion in the oil and gas industry is an often overlooked subject when evaluating the impact of an upset or failure due to corrosion. Costly issues can arise when as little as a single piece of equipment is not designed to properly mitigate corrosion. Not only is there a need to replace the failed piece of equipment but there are many other costs to consider. In this case study, a SAGD facility in northern Alberta is examined more

Degradation Mechanisms in the Oil & Gas Industry

A key activity carried out during the initial stages of designing an Integrity Management Program is to identify the degradation mechanisms that are possible in the facility. It is fundamental to understand the relevant mechanisms, their likelihood of occurring in the facility, and the impact that they may have on the facility. We have found that a good starting point is to reference API RP571 "Damage Mechanisms Affecting Fixed Equipment in the Refining Industry." This recommended practice describes degradation mechanisms found in refineries, affected materials, critical factors used to identify the mechanism, affected units or equipment, appearance or morphology of damage, prevention/mitigation measures, inspection and monitoring recommendations, and related mechanisms. References are also provided where the reader may be looking for additional information regarding the degradation mechanism.

Ammonite Corrosion Engineering uses API RP571 to identify the degradation mechanisms that are relevant for the client's facility and where necessary expands the list of mechanisms to include those not referenced by API RP571 . Photographs are used wherever possible to highlight the mechanisms' description. Information regarding these degradation mechanisms is then captured in a separate document for the client to use as a reference and for training purposes.
