Risk Assessment of Natural Gas Gathering Station & Pipeline Network

摘要

Risk assessment is one of the main tool followed by oil and gas industries in order to assess the hazards and risk in their facilities worldwide. Qualitative and quantitative risk assessments are carried out at various phases of the process industry from conceptual stage, design stage, construction stage, operational stage, decommissioning stage etc. The quantitative risk assessment is directed during the detailed design stage uses to decide the spacing and layout out of equipment's for safe operation and maintenance of oil and gas industries. The equipment layout and spacing is based on the safe distances are to be carried out on various design safety studies. In this work a study to carried out on upstream onshore natural gas gathering station and associated equipment's and pipeline network. The fire, explosion assessment and toxic gas dispersion are conducted in order to evaluate, how it effects on people, asset and environment. Whether the design protection systems are adequate enough to mitigate the consequences or any additional measures needed to be provided to reduce risk to acceptable level is analysed. Software models are used to do assess consequence of various accident scenarios are considered for this this study.
