We are: Registered, experienced, qualified Pressure Vessel Chartered Engineers,


We care: About pressure equipment, from inside and out, from manufacture to disposal, from top to bottom for the one vessel to many so that you can get on with running a profitable business and not worry about the legal or environmental issues around substandard, leaking or unsafe equipment.


We realise that:The journey through the inspection maze is sometimes longer than required, or needed, that's where we at Auzpec can help, coach and guide. 


We train, build corrosion loops/circuits,  allocate damage mechanisms, analyse consequence, study historical inspection data, review, integrity management plans, analyse for risk and plan for a better outcome.


Our experienced Inspectors and Engineers have been involved in RBI for over 20 years, Internationally, using many different systems.    


We provide:


• Assigning of corrosion loops/circuits  

• Allocation of damage mechanisms, 

• Likelihood analysis

• Consequence analysis, 

• Historical inspection data review, 

• Integrity management planning procedures

• Risk analysis  

• Planning for future inspections  

• Isometric piping drawn and photographic surveys

• Thickness Monitoring Location (TML) assignment.

• Failure Modes and Damage Mechanisms in RBI analysis


Our approach is as follows.

• Identify the internal and external operating and environmental conditions, age, design and operational loading. Data used and assumptions made should be validated and documented.

• Deterioration or degradation is sometimes used as a synonym for damage. However, damage mechanism is used throughout this document for consistency.

• Process conditions, as well as anticipated process changes, should be considered.

• Identifying trace constituents (ppm) in addition to the primary components in a process can be very important as trace constituents can have a significant effect on the damage mechanisms.

• Considering the materials, methods and details of fabrication, develop a list of the credible damage mechanisms that may have been present in past operation, be presently active, or may become active.

• Under certain circumstances, it may be preferable to list a specific damage mechanism and then list the various damage modes or ways that the damage mechanism may manifest itself. For example, general corrosion could result in a significant burst while localised corrosion might be more likely to result in a pinhole type leak.


All credible failure modes for each damage mechanism or damage mode should be considered.

Note it is possible to have two or more damage mechanisms at work on the same piece of equipment or piping component at the same time. An example of this could be stress corrosion cracking in combination with generalised or localised corrosion (thinning or pitting).



At Auzpec we have RPEQ CPEng(Aus and NZ) CEng(UK) Engineers and AICIP Inspectors who can help.
