Pipeline Route Optimization of Natural Gas Supply System to the Industrial Estate and Household Location: A Conceptual Model

Abstract

Energy demand in Indonesia is increasing rapidly especially for the industrial and household sector. Natural gas is more desirable as the energy source for both sectors. The pipeline is needed to transport natural gas from the supply region to the demand region. When a pipeline network is going to be built, one of the most important considerations is route selection. Pipeline route selection involves several factors such as distance route, environment, existing infrastructure, public safety, and cost estimation. The objective of this study is to develop a mathematic model to determine optimal gas pipeline route both in terms of investment costs and catastrophic cost as well as to select the location of the industrial estate and household in Semarang, Central Java as one of the priority regency in the government plan. The application of this study will be performed for the next research.
