Internship Experience – Chevron Pacific Indonesia 2013

I am a participant of Chevron Pacific Indonesia University Partnership Program 2013. Chevron Pacific Indonesia or CPI are one of the biggest Oil Production Sharing Contract in Indonesia. They manage big oil and gas blocks in Indonesia, such as Riau and East Kalimantan. Chevron also manage geothermal plant in West Java, the Salak and Daradjat field. Chevron University Partnership Program is one of their CSR program to foster university student participation on internship program in oil and gas company. On 2013, it was exclusive only for ITB and UGM students. Hope the program continue to give equal opportunity for all university in Indonesia.

In short, I applied for Facility Engineer Intern and got accepted as one of participant. First is administration selection, followed by psychology and aptitude test. If you passed, you will invited to panel interview section. Medical check up invitation will arrive if you pass the interview section. Induction day was held for all participants before assigned to specified operations. As for me, I was assigned to Sumatera Operation where the Duri and Minas oil field are existed.

Power Generation and Transmission Department

As a Facility Engineer Intern in Power Generation and Transmission Department, I was supervised by a lead mechanical engineer and a reliability mechanical engineer. Bang Albert Marihot was a lead mechanical engineer at that time, he had more than ten years experience in facility engineering field as he worked in Freeport (copper and gold mining company) and Indonesia Power (power plant) before. Pak Hendra Oktawira was a new reliability engineer, had experienced many years as reliability engineer at a petrochemical company.

The responsibility of PGT department is to supply and sustain electricity power for all Sumatera operation. That is including drilling and residence facility. If the power goes out, that means a reduced PGT’s key performance index. The department mostly habitated by electricity power engineers, project engineers, and mechanical engineers. Mechanical engineers mainly acted as reliability engineer of all equipments involved in power generation, transimssion and distribution process. I was assigned on the implementaion of Risk Based Inspection method on the transmission and distribution equipment. The equipment is steam turbine, gas turbine, heat exchanger power pole.

Power Pole

Electric Power Pole

Do not mind the electric things appear above, even at that time I did not really understand about the how electricity in power pole works. As a mechanical reliability engineer, our task is to maintain the mechanical integrity of the pole that sustain all electrical equipments. The pole sustain all mechanical loads from the weight of equipment and external load from wind forces. One pole falling down could cause disruption of the transmission of electric power for the operation, that means NPT that cause loss of money. Loss of money = blamed employee.

The unusual things done here are the Risk Based Inspection applied for the power pole equipment. RBI is usually applied for pressurized oil and gas equipment with high risk consequences. However, we applied the RBI methodology to the maintenance process of power pole. As you know before that RBI is documented in American Petroleum Institute (API) 580 and 581. They are standard which widely used for oil and gas equipment throughtout the industry. In RBI, we assigned each equipment a risk value and then group them based on their risk level. Each risk level might need different mitigation and maintenance effort. Risk defined as probability of failure (PoF) times the consequence of failure (CoF). In a more simple way, we sometimes use risk matrix to define the risk value. There is 3×3 matrix, 4×4 matrix, or 5×5 matrix which more complex. There may be an equipment that has very low probability of failure but might cause disastrous consequence when failure happen. RBI tried to accomodate the effects of both probability and consequence to make a proper preventive maintenance process. As for example: power pole in several Chevron areas were more susceptible to corrosion due to high H2S gas in the enviroment will raise the PoF. If we compare the poles to other in lower corrosion level area, those poles should be assigned a higher risk level so the maintenance treatment will be different. They might need extra thermal, NDT, or thickness inpsection more frequently than the lower risk one. That sums up my works in the internship period. Mostly I learned how maintenance engineer works. I sometimes attended meeting with the inspection vendor, weekly meeting with director, presenting my assessment and giving recommendation. I also gain knowledge of electricity generation process with their transmission and generations equipments.

Such a wonderful experience for a summer internship as an Facility Engineer! *Of course the money was also very good for a college student.
