SPED Maintenance & Turnaround Planning 2

Question 1

Which document establishes the authorized scope of work for a piping system turnaround before execution begins?

Accepted Answer

Scope freeze document

Answer

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?

Accepted Answer

To identify additional work items and verify scope accuracy

Answer

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:

Accepted Answer

Has zero float and directly controls overall completion date

Answer

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?

Accepted Answer

Radiographic testing (RT) profile method

Answer

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:

Accepted Answer

Reduce critical path duration by completing non-critical work before shutdown

Answer

Pre-installing scaffolding before shutdown eliminates this time from the critical path, compressing overall turnaround duration.
