Master of Mechanical Engineering : advance engineering mathematics

  One way to be the best Mechanical Engineer is to train ourself through pursuing Master of Mechanical Engineering. The study will be 3 semesters for learning advance knowledge – including advance engineering mathematics- and 1 semester for conducting research. In Mechanical Engineering, more than 50% study is related to mathematic and physics.  We must understand the distinction between pure mathematics and engineering mathematics. In engineering mathematics, we learn applied mathematics to solve technical problem during equipment design or during field troubleshooting. In advance engineering mathematic, we learn Fourier Series. By using Fourier approach, we can re-write a periodic curve[…]

Risk Based Inspection – Metric

Risk based inspection Metric     Risk Based Inspection is a study to develop inspection plan based on equipment risk ranking. Mathematically, Risk is defined as PoF x CoF. What is PoF ? PoF or Probability of failure is a rank that tell us about how likely a equipment will fail. CoF or Consequence of failure is a rank that tell us about how much failure impacts. In a simple way PoF, CoF and Risk are 3 terms that we used to rank all equipment in a company. Risk based inspection metric may consist of 3×3 , 4×4, 5×5 or[…]

Mechanical Engineer creates value from Risk Based Inspection

how to get a vlue from risk based inspection ? A wise man said “if you buy a product from a manufacturer at $100 and sell it again to customer at $120, it is traditional trader. You need more than that. Successful man is selling a product at $120 even there is not manufacturer available yet.” In previous articles, we learned about processing data to provide lower inspection cost. In simple way, we can classify that activities into 3 block diagram: input, process and output. IPO diagram : Input – Process – Output Input  : last inspection record, equipment data,[…]

Excel for Mechanical Engineer, cost saving by Risk Based Inspection

how to use excel for Risk Based Inspection? We will figure out inspection plan using data in the previous article. First we will find optimum inspection date base on fixed interval and RBI interval using simple excel spreadsheet. Use excel function “ + ; MAX”.   remark: next inspection – fixed = Last inspection date + fixed inspection interval ( 5 years) next inspection – RBI = Last inspection date + RBI inspection interval next inspection date = Maximum (optimum) value between next inspection – fixed and next – inspection RBI. We extend inspection interval using Risk Based Inspection study.[…]
