Shirin Rafigh received her BSc Degree in Chemical Engineering from Sharif University of Technology in 2004. She worked for a year as process engineer in an oil and gas company in Tehran, Iran, before she started her MSc in Advanced Chemical Engineering in Imperial College London in 2005. She then worked for 2 years as facilities engineer and technical consultant in Bayphase Ltd, an oil and gas consultancy, based in Camberley, UK. She started her PhD in UCL in 2008 in the area of pipeline safety and risk assessment.

Title: Modelling Outflow Following Failure of Pressurised Pipeline Systems Containing Low-vapour Pressure Liquids

Supervisors: Professor Haroun Mahgerefteh and Henk Witlox (DNV Risk)

Pipelines are extensively used to transport essential commodities over long distances. These commodities include water, natural gas, petroleum products and liquid hydrocarbons. Since theses commodities are required for human existence, the monitoring of pipelines becomes extremely fundamental. Hazardous liquid transmission via pipelines relies extensively on the integrity of the pipeline system. Any accidental loss of containment at any point along the pipeline can result in considerable environmental impact depending on local geography, as well as design and operational parameters. Any loss of commodity and transportation capacity can lead to monumental loss of revenue and adversely affect national income.

Several studies have been carried out to model the outflow following the failure of pressurised gas or two phase pipelines. However, despite its importance limited attention has been paid to the modelling of the failure of pipelines containing incompressible non-flashing liquids.The objective of the current study is to develop and test a robust mathematical model to predict the transient discharge rate upon rupture or puncture in a system of pipes connecting two storage vessels. Pipe bends and fittings, intermediate pumping, emergency isolation valve closure and pipeline terrain topography are also considered in the model.
