The design of gas pipeline requires information of gas rate and pressure of gas to be delivered. Investment for pipeline and compressor are not inexpensive, therefore economic study through optimization process is required to minimize the cost. In reality, gas demand increases over time so “static optimization of pipe size to deliver the gas will not fit to the condition. New pipeline might be installed to serve the increased demand in the future if the existing pipe size is designed just to serve the current demand, while oversized pipe diameter would be wasteful to serve the current demand. An optimization using dynamic model, then, would suit for the problem raised. This paper explains how dynamic model can assist gas pipeline design for increasing demand. This model wraps up the long term period of fulfilling gas demand with an optimum strategy of pipeline development. A case study presented in this paper outlines the dynamic model to optimize gas pipeline in Matindok Block, in Sulawesi. The economic aspect is also discussed as objective parameter in the optimization model. The study gives recommendation of constructed pipeline and compressor design based on technical aspect and economic analysis which satisfies all designconstrains.Keywords: gas transmission pipeline, dynamicoptimization
