 This work presents an optimisation framework for the routing and equipment design of main pipelines to be used for fluid transmission. There are many considerations in these design problems, involving various constraints, decisions and the associated costs for the construction, operation, maintenance, etc., of the system. In practice, engineers rely on experience, try out various design alternatives, and use simulators for engineering calculations, cost models, geographical information sys...

 Recent advances in pipe manufacturing techniques and pipeline construction have enabled the installation of larger diameter pipelines in ultra-deepwater locations (water depths greater than 1,500 meter). Results of recent work have demonstrated the beneficial effect of a modified UOE (U bending, O forming, expansion E) manufacturing approach on linepipe collapse resistance (Kashani 2008). Through the modified UOE fabrication process, in combination with low heat treatment process signific...

 This paper describes the principal theoretical concepts of the method used for constructing computer models of complex multiloop branched pipeline networks, and this method is based on the theory of graphs and two Kirchhoff’s laws applied to electrical circuits. The models make it possible to calculate velocities, flow rates, and pressures of a fluid medium in any section of pipeline networks, when the latter are considered as single hydraulic systems. On the basis of multivariant ca...

In this paper, Genetic Algorithm is used for optimal design of surge tank in pipeline systems under transient conditions. The Implicit Method of Characteristics is used for simulation of pipeline system. The objective of using GA is to optimize the cost of surge tank in system by minimizing its volume such that an existing pipeline can resist pressure surges induced by transient operation of the system. The method is applied to two example problems of transient flow caused by valve closure. The ...
