Here is some context to this case study:

On April 20, 2010, an explosion occurred on the Deepwater Horizon drilling rig in the Gulf

of Mexico, causing a fire and subsequent sinking of the rig. The accident led to the release of

millions of barrels of oil into the Gulf of Mexico, causing extensive environmental damage.

The accident was caused by a series of failures in the well's blowout preventer and the rig's

safety systems, which ultimately led to a catastrophic failure. The failure of these systems

and subsequent failures in other systems led to a domino effect that resulted in the oil spill.

The system boundary of investigation for the Deepwater Horizon oil spill can be defined as

the offshore oil drilling operation carried out by the Deepwater Horizon rig, owned by

Transocean and leased by British Petroleum (BP) [4]. The investigation includes the events

leading up to the explosion and subsequent oil spill, the response to the crisis, and the impact

on the environment, the economy, and the society [5].

The system boundary also encompasses the various interconnections and feedback loops

between the different components of the system, such as the wellhead, blowout preventer,

drilling mud, cement, and the various safety systems and procedures. The regulatory

framework and policies that were in place and the roles and responsibilities of the various

stakeholders involved in the incident are also part of the system boundary.

Q1)capture the essence of finding

Q2)Define scope,boundaries and objectives clearly

Q3)Define risk criteria and provide a quantified Tolerability of Risk(ToR) table

Q4)use FMECA technique to identify,quantify and mitigate sources of risk

Q5)Discuss the monitoring and treatment process
