SPED Maintenance & Turnaround Planning 2 — Questions and Answers
Question 1: Which document establishes the authorized scope of work for a piping system turnaround before execution begins?
- Work order package
- Scope freeze document (Correct answer)
- Pre-turnaround inspection report
- Punch list
Correct answer: Scope freeze document
The scope freeze document formally locks the approved scope of work to prevent unauthorized additions that drive cost and schedule overruns.
Question 2: What is the primary purpose of conducting a pre-turnaround walk-down of piping systems?
- To calculate hydrotest pressures
- To identify additional work items and verify scope accuracy (Correct answer)
- To train new operators on the unit
- To update as-built drawings
Correct answer: To identify additional work items and verify scope accuracy
Pre-turnaround walk-downs verify planned scope, identify hidden deficiencies, and reduce surprises during execution.
Question 3: A critical path activity in a turnaround schedule is best described as one that:
- Requires the most labor hours
- Has zero float and directly controls overall completion date (Correct answer)
- Involves the highest-pressure piping systems
- Must be completed by a licensed contractor
Correct answer: Has zero float and directly controls overall completion date
Critical path activities have zero float, meaning any delay directly extends the total turnaround duration.
Question 4: Which inspection method is most appropriate for detecting internal corrosion in an insulated piping system without removing insulation?
- Dye penetrant testing (PT)
- Radiographic testing (RT) profile method (Correct answer)
- Hydrostatic testing
- Positive material identification (PMI)
Correct answer: Radiographic testing (RT) profile method
Profile radiography can image pipe wall thickness through insulation, detecting internal metal loss without insulation removal.
Question 5: In turnaround planning, 'scaffolding pre-installation' is typically performed to:
- Satisfy OSHA fall protection requirements year-round
- Reduce critical path duration by completing non-critical work before shutdown (Correct answer)
- Allow contractors to begin billing earlier
- Comply with insulation replacement schedules
Correct answer: Reduce critical path duration by completing non-critical work before shutdown
Pre-installing scaffolding before shutdown eliminates this time from the critical path, compressing overall turnaround duration.
Question 6: What does the term 'backlog management' refer to in the context of piping maintenance planning?
- Tracking overdue purchase orders for pipe fittings
- Systematic tracking and prioritization of deferred maintenance work items (Correct answer)
- Managing the queue of new pipe routing designs
- Recording historical repair data in CMMS
Correct answer: Systematic tracking and prioritization of deferred maintenance work items
Backlog management involves cataloging, prioritizing, and scheduling deferred maintenance items to optimize resource allocation.
Question 7: When planning piping repairs during a turnaround, which factor most directly determines whether a hot tap or a shutdown repair is required?
- The pipe material specification
- Whether the system can be safely isolated and depressurized (Correct answer)
- The diameter of the pipe requiring repair
- The geographic location of the facility
Correct answer: Whether the system can be safely isolated and depressurized
If the system can be safely isolated, a conventional shutdown repair is preferred; hot tapping is used when safe isolation is impractical.
