1. Aims & Objectives

  1. Development of an accurate and rigorous pipeline rupture outflow model which takes into account the entire phenomena governing the discharge process including non-ideal thermodynamic behavior, multi-phase heterogeneous flow, inter-phase heat and mass transfer as well as fluid/pipe wall friction and heat transfer.
  2. Extension of the outflow model developed above to simulate the dynamic response of inline Emergency Shutdown Valves (ESDV).
  3. Development of a fully coupled finite element fluid/structure interaction model to accurately determine the pipeline material toughness requirement in order to resist running brittle fractures with particular reference to ethylene pipelines.
  4. Conducting pipeline rupture tests to validate and refine the models developed.
  5. Coupling the ESDV model in (ii) above with a cost/benefit analysis tool to enable the optimal positioning of inline ESDV.
  6. In close consultation with a major stakeholder, demonstrate the efficacy of the validated models developed though their application to a real pipeline system in Qatar chosen as a case study.
