Safety and risk prediction of port oil piping transportation system impacted by climate-weather change process

The paper is concerned with an application of the simplified impact model of critical infrastructure safety related to climate-weather change process to safety and risk prediction for port oil piping transportation system operating at the variable climate-weather conditions. There are presented the identified piping system safety parameters and the climate-weather change process parameters and characteristics. Moreover, there are presented evaluated by experts the coefficients of the climate-weather impact on the piping subsystems intensities of ageing. Further, there are determined the three-state system safety function, the expected values and standard deviations of the lifetimes in the safety state subsets and in the particular safety states, the risk function, the fragility curve and other safety and resilience indicators for port oil piping transportation system.
