Paper Number: PSIG-1506
... initiating an automatic pipeline shutdown upon receipt of a system-based rupture alarm. These types of performance expectation are challenging to achieve with conventional, model-based, leak-detection systems (i.e. CPM-RTTMs) as the reliability measured in terms of the false alarm rate is typically too high...
