Abstract
Capture, Transport and storage of CO2 (CTSC) is a novel technology for mitigating CO2 emissions in the atmosphere and reduce the climate change impacts on ecosystems, human beings and natural resources. However, potential technical, environmental, health, safety and social risks associated with CTSC activities should be studied in order to reassure the stakeholders that CTSC will not have adverse effects on human beings and environment. CTSC can be considered as a complex socio-technical system, for which traditional risk management approaches are not appropriate. An integrated approach is required for risk management of CTSC. The integrated approach should cover the interactions of capture, transport and storage, as well as the technical, organizational and human aspects of risk. The purpose is to evaluate the performance of safety control system in CO2 Capture, Transport and Storage chain. The idea is to develop a dynamic risk management framework by modeling the principal variables that are significant in terms of safety of CTSC, and study the evolution of these variables over time. These variables can be the ones that are integrated into the Safety Management System (SMS) in order to implement them into a scorecard containing the variation of key performance indicators over time, both in normal operation of the system, and in case of a failure. In this context, system dynamics is used for modeling. The model will allow us to know how the interaction of different variables (technique, organizational or human) may result in variation of performance indicators. The proposed methodology is based on eight steps that will be presented in the paper. The proposed framework is applied to an integrated CTSC project with an enterprise as the owner, and several firms and organizations as operators, designers and stakeholders. In this paper, the approach will be explained in detail and some preliminary results will be presented.
