IDMS integrity database management system
First time I saw an IDMS integrity Database Management System was in 2008 when I joined RBI engineer Training. In 2013, I joined a IDMS user training and in 2014 I attended “IDMS train the trainer”. Now I am a SME – subject expert matter, IDMS admin and a trainer for IDMS software.
IDMS integrity database management system – understanding Fixed equipment
You need have a good technical background to use an IDMS software or at least you have 1 year field experience related to fixed equipment. Fixed equipment example are tank, pressure vessel, vent stack, flare stack, pipe, pipeline, PSV, valve, breather valve etc. You need understand material specifications used in fixed equipment such as A516 grade 60/70 for pressure vessel, A36 for tank, A106 grade B for process piping and power piping, API 5L grade B for pipeline, A105 for flange material etc.
IDMS integrity database management system – understanding design code
you also need to understand the design code for fixed equipment. ASME B31.3 for Process Piping, ASME Boiler & Pressure Code section VIII Div-1 for Pressure vessel, ASME B31.4 for liquid hydrocarbon transportation pipeline, ASME B31.8 for gas transportation pipeline and API 650 for tank. the most important calculation is thickness requirement and MAWP Maximum allowable working pressure.
IDMS integrity database management system – understanding inspection record
we record all inspection result in IDMS software. inspection method used are ultrasonic thickness measurement (UTM) for Tank, UTM on Pressure vessel, UTM on Heat exchanger, UTM & LRUT Long Range Ultrasonic Thikness for pipeline. we record thickness measurement result and calculate corrosion rate occurred to measure remaining life of an equipment. Risk based Inspection use these inpection record to develop Probability of failure ( PoF).
