Thermography serves as a non-destructive tool in the analysis and evaluation of electrical distribution equipment critical to the operation of the vessel. 

Thermographic Inspections are also useful in the detection of boiler lagging deficiencies, faulty bearings, steam trap effectiveness, and motor insulation. Thermography is a widely used tool in all facets of industry to measure anywhere where a fault can be predicted by a temperature differential.

For each problem area, absolute surface temperature measurements, ambient temperatures of surrounding surfaces, and the relative temperature rise is obtained. Computer-generated white light and infrared photos are then taken to identify the equipment, its location, its problems, and recommended corrective action.

Motor Controller	Typical "hotspot"
Criteria Temperature rises are placed into four categories, as follows:
1° - 10° C	Corrective measures required at next scheduled maintenance period or as scheduling permits
10° - 20° C	Corrective measures required on a Priority-scheduling basis
20° - 30° C	Corrective measures required as soon as possible
30° C and up	Corrective measures required immediately
