TWI offers RBI solutions to Members as part of its risk and reliability engineering services. Our exhaustive knowledge of materials degradation processes, and demonstrable track record in this area, mean Member companies can rely on us to develop the right plan for each scenario.
Using an established methodology and TWI’s bespoke RiskWISE® software, we can develop maintenance or replacement solutions, giving guidance on managing your assets in the most effective manner, from individual component studies through to turnkey, plant-wide projects – tailored to your needs. Our asset integrity management and plant life assessment services work together to maximise the reliability and efficiency of a structure or component.
TWI has recently developed quantitative data trending as a means of mitigating risk in equipment where reliable data is scarce or unavailable. This, coupled with RiskWISE 5 (API 581 compliant) allows assessments to be conducted with greater speed and accuracy than ever before.
Conducting an RBI
Risk-based inspection can be done in a qualitative, semi-quantitative or quantitative manner, using guidance from standards applicable to different situations such as API 581 for oil and gas and petro-chemical scenarios, and DNV-RP F116 for subsea pipeline. Other assets for which RBIs are valuable are storage tanks, onshore pipelines and structures, and power generation components such as steam turbines, gas turbines, heat recovery steam generators and balance-of-plant systems.
The essential element in all these situations is a risk analysis: the combination of an assessment of the likelihood of failure due to damage, deterioration or degradation, and the consequences of any such failure. The information gained from this process is used to identify the type and rate of damage that could potentially occur and the equipment or locations where failure would give rise to danger of different degrees.
