why we use asset integrity management software?
In oil and gas industry, we operate thousand equipment. For each equipment, there are thousands of inspection data. Due to large quantity, we need a database to manage all equipment and its inspection record. We call it as asset integrity management software -also known as IDMS– to manage equipment integrity. Basically, in asset integrity management software, there are 2 technical sides. First is server side which is usually used in SQL Server, Oracle or MySQL. The other side is “client software” that installed in user PC. The client software is used to input and read the data. All data is stored on a server.
benefit of asset Integrity management software
The benefit of asset integrity management software improves safety & efficiency, streamline regulatory compliance, prolong equipment life and risk based inspection. Some feature or module provided in IDMS are:
- equipment list: all equipment are recorded in this software and each equipment has equipment number
- operating condition / operating window: we record operation pressure, operation temperature
- equipment design condition like design temperature, design pressure
- attachment for drawing. we can save all drawing related with equipment
- manufacture data to record nameplate, ASME Stamp etc
- design basis
- scheduling. this module is used to conduct planning and scheduling activity.
- inspection result. this module is used to record inspection data like thickness measurement ) UTM ) or visual inspection
- inspection history.
- ITPM – inspection test & preventive maintenance
- Risk Based Inspection assessment record
- inspection recommendation
- damage mechanism
- MAWP or Maximum Allowable Working Pressure
- remaining life assessment resulted from corrosion rate monitoring and minimum design thickness
- equipment index
- criticality assessment
- data visualization
Asset integrity management software also provides DASHBOARD to see the summary of equipment information. In the next article, I will explain some best practices using Asset integrity management software.
what are asset integrity and asset integrity management?
asset integrity is an ability of an asset (usually fixed equipment, piping, pipeline ) to perform its function during its service life. for example, a pipeline. Its function is to contain a service fluid and transport it from 1 location to other location. therefore the discussion of asset integrity of pipeline is about how much pressure can be operated or known as MAWP – maximum allowable working pressure. a pipeline engineer or pipeline inspector calculate the MAWP based on the minimum thickness of pipeline.
asset data –> criticality assessment –> Inspection test and Preventive Maintenance (ITPM) –> inspection schedule –> inspection result –> corrosion rate information and minimum thickness –> Maximum Allowable working pressure & recommendation of repair.
Asset Integrity Management (AIM) is a system or policy to manage their fixed asset. In Asset Integrity Management, is it explained who is responsible for a certain task, how we should make an asset criticality assessment and how to prioritize the critical asset.
inspection method used in asset integrity
inspector or engineer conduct an inspection to verify fixed asset/pipeline condition. below are some inspection method usually used:
- UTM: ultrasonic thickness measurement
- LRUT: Long range ultrasonic thickness
- ILI: in line inspection
UTM can be used for Pressure vessel inspection, Tank inspection, Piping inspection or pipeline inspection. LRUT mostly used for pipeline inspection. ILI only used for long pipeline inspection. all these methods are used to measure the thickness of fixed asset/pipeline/piping.
minimum required thickness in asset integrity
minimum thickness is a threshold in asset integrity. this thickness is used to calculate MAWP-maximum allowable working pressure.
