This thesis aims to study the optimization of the supply fuel system of pipeline by improving the pumps system from use pump size 1850 kW (2 pupms) and use only control valve. We design new system by use pump size 1850 kW (2 pumps) with variable speed motors (VSD). In this way we can control stability of opening and closing of the valve at 100% and use adjusting of the frequency of VSD as follow typing of fuel. To analysing of efficiency system we will use fuel 4 type that have different coefficient of density are JET A1 Disel B91 and B95. And then we compared the relationship between the quantity of each fuel per time and usage of power for the old system and new design that we found the new design as analyze the result and as follow the theory of Affinity Law have the value of efficacy more than. And it also can save energy cost to 52.13%
