In the frame of SYNER-G Work Package 3 - Fragility functions of elements at risk - and Task 3.2 (Fragility functions for utility system network), the present deliverable aims at presenting fragility curves for components of gas and oil system networks (Sub-task 3.2.2). These fragility functions need to be applicable to the specific European context and they are intended to be integrated to the general evaluation of the systemic vulnerability. The following network components are considered: buried pipelines, storage tanks and processing facilities (including compression stations, pumping stations). Based on a literature review, it is found that the available fragility functions are mostly empirical and should be applied to the European context, given the current lack of data needed to validate potential analytical methods of vulnerability assessment. For buried pipelines, fragility relations from (ALA, 2001) are selected, with respect to both wave propagation and ground failure. The curves from the HAZUS methodology (NIBS, 2004) may be used for storage tanks and compression stations, as these facilities are decomposed into a fault-tree analysis.
