The pipeline operation of a high pour point oil commonly deals with some troubles due to the descending temperature along the pipeline that would make the oil become more viscous, so that it will need a high pressure difference to allow the oil to flow - and, in a worse condition - the oil flow would possibly be stopped if the temperature goes down as low as its pour point. however, there are several techniques could be done to maintain the oil flow along the pipeline, which are; by attaching heater, insulator, adding a chemical additive into the fluid, or by simply adding water. The main idea is to keep the oil at a relatively high temperature so that it will keep flowing. In this study, the decisive solution was restricted on the using on heater and insulator only. The design of the high pour point oil transportation must be conducted effectively, both in the other problems during the operation and maintenance as far as the system's lifetime.<p>The system or model being used consists of 2 sources and 1 sink, which transport the high pour point oil. The transported oil is having 90 degrees F of pour point and cloud point of about 100 degrees F. The optimization was conducted referring to the total cost which consists of investment cost and operating cost in a certain period of time, and it was assumed to be a uniform annual cost as far as the system's lifetime. The constraints of the optimized system are the maximum allowable working pressure for each pipe, maximum allowable temperature for each pipe, system minimum outlet pressure, system inlet pressure, eruptional velocity, and fluid rate.<p>The presented scenario was generated by using a simulator - which already requires the constraints as it was stated before. The proposed scenario is the scenario with the lowest cost, and then, it was re-analyzed on the basis of the increment and the descent of fluid rate which could occure as long as the system's lifetime. the analysis is also conducted when there is a drastic in the environment's temperature descent so that it would need the addition of several heater units on to the system.
