System safety analysis of well-control equipment
In the wake of recent disasters in the oil and gas E and P and petrochemical industries, the importance of system safety analysis is becoming recognized. Reliability assessment techniques, which were developed in the nuclear-power-generation and defense industries, are potentially valuable tools for engineers in the offshore oil and gas business. BOP's and their control systems used on offshore rigs are typically made up of several subsystems. Hydraulic, pneumatic, and electronic modules are interfaced to provide functional control and monitoring of the mechanical BOP's and valves. Two techniques are used for reliability analysis of a blowout preventer (BOP) and a hydraulic control system. Failure modes and effects analysis (FMEA) examines each part and the consequences of its malfunction. Fault tree analysis (FTA) traces undesired events to their causes. Reliability calculations and data sources are addressed.
