Recent major accidents in the offshore oil and gas (O&G) industry have showed inadequate assessment of system risk and demonstrated the need to improve risk analysis. While direct causes often differ, the failure to update risk evaluation on the basis of system changes/modifications has been a recurring problem. Risk is traditionally defined as a measure of the accident likelihood and the magnitude of loss, usually assessed as damage to people, to the environment, and/or economic loss. Recent revisions of such definition include also aspects of uncertainty. However, Quantitative Risk Assessment (QRA) in the offshore O&G industry is based on consolidated procedures and methods, where periodic evaluation and update of risk is not commonly carried out. Several methodologies were recently developed for dynamic risk analysis of the offshore O&G industry. Dynamic fault trees, Markov chain models for the life-cycle analysis, and Weibull failure analysis may be used for dynamic frequency evaluation and risk assessment update. Moreover, dynamic risk assessment methods were developed in order to evaluate the risk by updating initial failure probabilities of events (causes) and safety barriers as new information are made available. However, the mentioned techniques are not widely applied in the common O&G offshore practice due to several reasons, among which their complexity has a primary role. More intuitive approaches focusing on a selected number of critical factors have also been suggested, such as the Risk Barometer or the TEC2O. Such techniques are based on the evaluation of technical, operational and organizational factors. The methodology allows supporting periodic update of QRA by collecting and aggregating a set of indicators. However, their effectiveness relies on continuous monitoring activity and realtime data capturing. For this reason, this contribution focuses on the coupling of such methods with sensors of different nature located in or around and offshore O&G system. The inheritance from the Centre for Integrated Operations in the Petroleum Industries represents the basis of such study. Such approach may be beneficial for several cases in which (quasi) real-time risk evaluation may support critical operations. Two representative cases have been described: i) erosion and corrosion issues due to sand production; and ii) oil production in environmental sensitive areas. In both the cases, dynamic risk analysis may employ real-time data provided by sand, corrosion and leak detectors. A simulation of dynamic risk analysis has demonstrated how the variation of such data can affect the overall risk picture. In fact, this risk assessment approach has not only the capability to continuously iterate and outline improved system risk pictures, but it can also compare its results with sensor-measured data and allow for calibration. This can potentially guarantee progressive improvement of the method reliability for appropriate support to safety-critical decisions.

Environmental impact from offshore oil and gas exploration and production is likely to arise from five main sources—produced formation water, drilling fluids and cuttiftgs, industrial chemicals used in production activities, accidental oil spills and the physical disruption of the marine environment by coastal and offshore engineering works. The principle task of environmental managers is to evaluate the risk of impact on the marine environment from their company's activities and to formulate and implement company policy and procedures aimed at minimising this risk. Of critical importance is the determination of the extent and scope of the environmental program designed to control and monitor impacts.The development of environmental management programs in the oil and gas industry involves two main processes—ecological risk assessment and formulation of a monitoring program. This review outlines the steps involved in ecological risk assessment with specific reference to the offshore oil and gas industry. Information is presented on the basic principles involved in risk assessment, the main source of environmental impact from offshore oil and gas exploration and production and the different approaches that can be used to predict and monitor impacts. Approaches for improving the cost efficiency of ecotoxicological testing are discussed. Results of recent ecotoxicological studies on a biocide preparation and two corrosion inhibitors used in oil and gas production activities on the North West Shelf are also presented.

This paper presents a quantitative risk assessment study on a Floating, Production, Storage and Offloading Vessel that operate in Brazilian offshore oil and gas production waters. In particular a study of the risks applied to a Storage Unit and Transfer Oil, focusing on the physical, especially in operations involving storage and handling of flammable liquids. The results showed that the unit must take safety measures process, because a failure in the system can affect other units; the level of security for the population of the ship is within the acceptable.

This study presents an analysis of the causes and consequences of the largest offshore platform accidents associated with oil and gas production. The research on this problem allows improving the reliability of risk assessment associated with offshore oil and gas production, as well as developing methods for improving the fire safety of oil and gas platforms under various operating conditions.
