“…Graham et al (2005) performed a technical and economic risk analysis on a number of new subsea deep-water fields. Lage et al (2006) developed a methodology comprising hazard and operability analysis (HAZOP) and quantitative risk assessment techniques to identify and prioritize risk reduction measures for high-rate subsea gas wells. Morgan et al (2008) discussed different risk mitigation strategies for subsea facilities operating in cold weather in the East coast of Canada.…”

“…These threats face the safe operation of both the offshore and onshore drilling and production operations. Although, a number of predictable risk assessment approaches and barriers have played important role in identifying major risk in drilling operation, and on other oil and gas facilities [9][10]. Although, most of these barriers have several advantages and disadvantages due to their structural limitations [11].…”

“…The HAZOP team was made up of more than twenty (20) professionals from five different companies. The process started with the identification of the hazards or operational problems that can cause adverse consequences or degenerate to such [9]. In another study, following the 1988 disaster on the Piper Alpha Platform which claimed the life of about 167 personnel's, the oil and gas industry was under great pressure to exert more efforts in systemic hazard analysis and risk assessment of their operations.…”

The application of HAZOP and BowtieXP methodologies of risk assessment using the Macondo oil well blowout as a case study has been investigated. This study is aimed, to compare and contrast between the HAZOP and BowtieXP methodologies of risk management using the Macondo oil well blowout as a case study. Hence, to accomplish the set aim of the study, the study envisions the Macondo oil well blowout as a scenario, which objectively vector: to evaluate risk management of the Macondo blowout using the Bowtie methodology; to assess risk management of the Macondo blow out using the HAZOP methodology; to prioritize risk assessment methodology within the risk management process; and to show the causes, failed controls, top event, impact, and consequences of the Macondo oil well blowout. To perform the Bowtie Analysis, several steps were followed to ensure an accurate representation of the Bowtie Diagram. Firstly, The TOP EVENT was established. This was the most critical step in Bowtie XP Risk tool. The choice of the TOP EVENT was guided by some questions: What is the risk event? At what point was the safety control lost? At what point did the root causes lead to, and that eventually results in the top event? Next, the preceding events and root causes threats were established. The choices made addressed answered the aforementioned questions relating to the risk controls which failed, the human factors and behaviour which played a role in the elevation of danger and the root causes of the Top Event. This study concludes that the major event of drilling an oil well is a BLOWOUT, which may lead to a catastrophe, and this was identified by both the HAZOP and BowtieXP as STUDY NODES and TOP EVENT, respectively. The consequences of a failed control blowout are Fire, Explosion, Fatal loss of lives, and environmental pollution.

Most risk analysis approaches are static; failing to capture evolving conditions. Blowout, the most feared accident during a drilling operation, is a complex and dynamic event. The traditional risk analysis methods are useful in the early design stage of drilling operation while falling short during evolving operational decision making. A new dynamic risk analysis approach is presented to capture evolving situations through dynamic probability and consequence models. The dynamic consequence models, the focus of this study, are developed in terms of loss functions. These models are subsequently integrated with the probability to estimate operational risk, providing a real-time risk analysis. The real-time evolving situation is considered dependent on the changing bottom-hole pressure as drilling progresses. The application of the methodology and models are demonstrated with a case study of an offshore drilling operation evolving to a blowout.
