| Offshore oil development and construction are high-risk operations. Once has the accident often to create the serious personnel, the property damage, even is the ecological disaster. In order to minimize the risk of offshore oil development job, there is an urgent need for risk assessment in oilfield development construction phase, the analysis identifies development job in security risk, and to take effective risk prevention and control measures to avoid or reduce the risk of accidents and incidents arising from the adverse effects.This paper begins with a risk management situation and development trend developed, introduced a risk assessment related to the theory that explains the risks of definitions and the nature of the risk, and for general risk management in four steps: hazard identification, risk assessment, risk preparedness and risk monitoring is discussed in detail. On this basis on the development and construction of offshore platforms stages commonly used security risk analysis methods and comparative analysis. On this basis on the development and construction of offshore platforms stages commonly used security risk analysis methods and comparative analysis. Highlights of this risk assessment HAZOP analysis of selected works, the analysis process and analysis steps, and pointed out the risk assessment HAZOP method benefits and limitations, as a reasonable selection of the analytical method provides a useful reference. Finally, this article uses the HAZOP analysis Bozhong 34-3 oilfield wellhead protection of the design process for security risk assessment. Through analysis, evaluation processes all the origin and cause of the deviation of the consequences of the system has the appropriate security measures to meet the design and operational requirements. For the assessment of the problems presented safety recommendations. For the Bozhong 34-3 oilfield construction and security operational follow-up provided useful guidance and strong protection. |
