The decisions made before and during a turnaround window are critical with regards to whether an outage will be completed on time and within budget.  Perhaps even more importantly, these decisions can drastically affect the long-term reliability of the equipment during the next planned operational run.

Plan ahead and establish go/no-go criteria in advance of the outage for critical equipment items that are known to be bad actors and/or are known to pose a risk to critical path in the shutdown schedule. Establish a turnaround problem-solving team that is experienced in damage mechanism identification, Fitness-For-Service assessments, and equipment repairs.  The problem-solving team can be comprised of all onsite personnel or a combination of onsite and remote personnel.
