Risk-Based Design Of Oil And Gas Pipelines, Risers

摘要

The production and transportation of hydrocarbon products involves complex process systems. The components in such a process system are exposed to extreme operational and environmental conditions. To ensure safe and continuous operation, it is important to identify probable risk sources and assess the integrity of the pipeline to avoid accidental or catastrophic failures. A traditional integrity assessment can be a time-consuming, complex and expensive process. However, incorporating a risk-based design (RBD) is an alternative method to protect a pipeline against corrosion dependent defects or cracks. The probability of accidental or catastrophic failure can be minimized or avoided by considering future risk sources in the early stage of the design. The risk-based design methodology is framed in the flow chart (Figure 1).
