Offshore planning
Can the generator be serviced on board?
Access, removal clearance and lifting equipment can change the scope of offshore maintenance. Two surveys show why these conditions need review before an outage.

Decisions before the next outage
Temperature and maintenance
Temporary RTDs: what remains for major maintenance
Restoring a temperature signal and completing a permanent installation are different scopes. A field record helps plan the follow-up.

Mechanical diagnostics
Vibration and temperature: narrowing the assessment
An elevated reading helps direct the investigation. Load, phase and machine-train displacement help assess a possible relationship with alignment.

Maintenance history
BRUSH BDAX: from L3 to L4, history defines the next outage
Reports from different years distinguish cleaning, mechanical work and follow-up. Reviewing them together helps define a scope with outstanding items in view.

Access and handling
Removing a generator from an enclosure: plan its return too
Restricted-access handling includes disconnection, the exit route, return, alignment and verification. The Stamford record shows why these steps belong in the scope.
