| Abstract | This study was structure, conduct and performance of the risk assessment and safety management of offshore drilling and production operation, had main four objectives: (1) Risk Assessment of offshore drilling and production platform (2) Safety Climate and Safety Management Practice in offshore environments (3) Identifying Root Causes of Offshore accidents (4) Investigate the Safety and Situation Awareness of offshore crews. Risk can not be avoided especially for complex projects like offshore drilling and production platform. The risk events of drilling and production platforms were ranked according to their occurrence and impact. The principal elements required to manage and mitigate higher risks are generally considered by :To eliminate or minimize the hazards by design (e.g. inherently safety, separating the person from the hazard); To prevent realization of the hazard (e.g. good inspection, maintenance,); To prevent escalation of the hazard (e.g. blowdown); To control the hazard (e.g. provision of active or passive fire protection); To ensure that personnel can reach a place of safety for any credible event (e.g. adequate evacuation, escape, and rescue) followed to As Low As Reasonable Principle(ALARP). `Safety Climate Assessment Toolkit', an assessment technique, based on the use of multiple methods, was developed for assess the safety climate and safety management practice in offshore environments and seeks to build on current industry initiatives, such as the cross industry leadership initiative, general safety behabiour, appreciation of risk etc. Offshore accident investigation techniques and reporting systems identify what type of accidents occur and how they occurred. Accident root causes tracing model (ARCTM) proposes that accidents occur due to three root causes like, failing to identify an unsafe condition that existed before an activity was started or that developed after an activity was started; deciding to proceed with a work activity after the worker identifies an existing unsafe condition; and deciding to act unsafe regardless of initial conditions of the work environment. Research finding showed that unsafe conditions are due to four main causes as Management actions/inactions; unsafe acts of worker or coworker; non-human-related event(s); an unsafe condition that is a natural part of the initial operation site conditions. One factor to the occurrence of accidents in offshore installations is a reduction in the `Situation Awareness' (SA).Good SA is essential when work is potentially hazardous, as workers must accurately discern and monitor conditions if they are to reduce accidents. Accident analyses have shown that a team can lose their shared awareness of the situation when it is vital to the safety of their operation. This may be particularly relevant to drill crews given the interactive and hazardous nature of their work. In this way, lack of/reduced SA may be a predictor of the likelihood of an accident occurring. This part of the report was to presents a brief history of SA, an overview of the study, a preliminary review of an accident database, and results from interviews with onshore and offshore oil and gas industry personnel |
