Question 1: Scenario-Based Human Reliability Analysis (HRA) Select a real-world offshore accident (e.g., Deepwater Horizon (2010), Piper Alpha (1988), or another documented case) and choose a specific failure scenario (e.g., procedural violation, operator misjudgement, failure to act in time). Conduct a THERP, HEART, and CREAM analysis. 1.1 THERP Analysis Event Tree Construction: Construct a THERP-based event tree to analyse the sequence of human errors leading to the accident. Human Error Probability (HEP) Estimation: Use THERP tables to estimate HEPs for key tasks and discuss their implications. 1.2 HEART Analysis Task Classification C Nominal HEP: Identify the Generic Task Type (GTT) and determine the nominal Human Error Probability (HEP). Error Producing Conditions (EPCs) C APOA: Identify Error Producing Conditions (EPCs) and assess their impact (APOA). Adjusted HEP Calculation C Justification: Calculate the adjusted HEP and provide detailed justification for assumptions. HEART-Based Recommendations: Provide industry interventions to reduce HEP. 1.3 CREAM Analysis Common Performance Condition (CPC) Analysis : Assess CPCs and assign the appropriate COCOM control mode (Strategic, Tactical, Opportunistic, or Scrambled). Human Error Probability Estimation: CPC evaluations determine the human error probability range. Justification Using Literature C Safety Reports: Support assumptions with academic literature and offshore safety reports. CREAM-Based Recommendations: Provide systemic safety culture improvements based on CREAM analysis.
