SUMMARY
The utilization of computational fluid dynamics tools continue to gain growing interest from pipeline designers and transient flows simulators. Transient flow software with robust graphical user interface (GUI) capable to compute transient flows characteristics and modeling of selection of pipefittings and its associated components are arguably preferred, because of cost effectiveness and straightforward to use. To this aim, in this paper, the utilization of computer-based method for the prediction of transient flow phenomena in crude oil transportation pipelines of 52 km loading and offloading offshore terminal is developed. A transient solver with credible GUI was used for the implementation of design and transient analysis of the crude oil transportation pipeline system. The findings from the simulations provided profound understanding and predictions of transient flows regime in the pipeline that would be relevant to carrying-out risk assessment, control and mitigation on similar tangible pipeline systems. In addition, modified design rules for transient flow assessment, control and risk mitigation of crude oil pipeline at the design stage are presented in a flow chart format.
