Young, smart and diligent… fresh graduate engineer

fresh graduate engineer As long as I became an engineer, I was a mentor for 5 apprentices. 2 persons are already employed as engineers at an Oil and Gas Operating Company and 1 person working in an oil and gas Service Company. They got the job very easily, in a matter of months since graduating from college. They have the same characteristics. Young, smart and diligent. They have almost perfect academic score as fresh graduate engineer. The world of work is full of competition. Only people who are ready to face the competition will succeed. Wise man say “if you fail to prepare a job, you are preparing for the job’s failure“. And sad but true, your rival is waiting for you to fail. There are several criteria that need to be considered by students of mechanical engineering or other engineering in order to have an acceptable job opportunity when graduated from college. This criteria I got from some leaders who often do interviews. Smart.  This is the most important and basic thing. Every leader would want to have a smart member so as to contribute as much as possible. Smart employees, can solve problems or obstacles by themselves without[…]

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 with sin & cos equation. Refer to above drawing, blue curve is original which can be approached by black curve.   In this stage, engineering mathematic can provide nearest solution but not exact solution. It is not 100% correct, but can be 99% correct. In most cases, we are satisfy with 99% correct solution. Another interesting subject is about “forced differential equation” or Forced DE. This subject can be applied to get solution of vibration problem, let say during car shock-breaker design analysis. Common problem is about a spring supporting a part or component (mass m kg, spring damper c[…]

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 even 6×6. For a company has a small quantity of equipment, they may choose to use 3×3 metric. But for company that have a lot of equipment -e.g. 1,000,000- with wide range of consequence, they may prefer to use 6×6 metric. This metric tell us about how detail we group the equipment. In 6×6 metric, we group probability of failure to 6 categories and group consequence of failure to 6 categories. Risk based inspection approach Risk based inspection may use qualitative approach, quantitative approach or even semi-quantitative approach. In qualitative approach, we likely use “expert” team to qualify the PoF[…]

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, Risk Based Inspection-RBI study, inspection cost Process  : inspection planning using simple tool i.e. excel spreadsheet Output : inspection schedule, inspection budget and the most important is “lower inspection cost by 50%” Customer : his supervisor, Inspection Manager It just an example of Mechanical engineer job in oil and gas industry. For average mechanical engineer, he only think about inspection schedule & inspection budget for normal process. Yes, it was satisfy his leader. But, for successful Mechanical Engineer, he will think alternate process to create more value to the company. In this example, the value is lower inspection cost by[…]
