A turnaround 'opportunity job' refers to work that:
Answer: Is added because the system is already shut down, though not originally planned
Opportunity jobs leverage the existing shutdown to address items that would otherwise require a separate outage, though they must be evaluated for schedule impact.
Which document defines the minimum wall thickness below which a piping component must be replaced or repaired?
Answer: Calculated minimum required thickness (t_min) per B31.3
ASME B31.3 formulas establish minimum required wall thickness based on design pressure, allowable stress, and diameter; inspection findings are compared against this value.
What is the main advantage of using a Computerized Maintenance Management System (CMMS) in turnaround planning?
Answer: It centralizes work order management, history, and resource tracking in one platform
A CMMS integrates work orders, equipment history, spare parts, and scheduling data, improving planning accuracy and execution control.
During a turnaround, 'simultaneous operations' (SIMOPS) planning is required when:
Answer: Multiple work activities occur near each other and could create combined hazards
SIMOPS planning identifies and manages conflicts between concurrent activities that could create hazardous interactions, such as hot work near gas testing.
Which of the following best describes a 'risk-based inspection' (RBI) approach to turnaround interval planning?
Answer: Using probability and consequence of failure to prioritize and optimize inspection scope and frequency
RBI per API 580/581 combines probability of failure and consequence to allocate inspection resources where risk reduction is greatest.
What is the purpose of 'post-turnaround critique' or lessons learned sessions?
Answer: To capture successes and failures to improve planning and execution of future turnarounds
Post-turnaround critiques systematically identify what worked and what failed, feeding improvements into the next turnaround cycle's planning phase.
In piping maintenance, 'corrosion under insulation' (CUI) is particularly dangerous because:
Answer: It is hidden from visual inspection and can cause sudden failures without obvious external signs
CUI occurs beneath insulation where moisture traps against the pipe surface, making it invisible externally and prone to causing unexpected failures.
