What is Thermography?

All objects above absolute zero (-273C) emit infrared

energy.

Thermal Imaging Cameras are able to visualize this energyand calibrate it so that surface temperatures can bemeasured and changes in surface temperature can beobserved.

Experienced Thermographers with high resolutionequipment are able to observe, capture and analyze thesechanges and are then able to identify and report defects or

anomalies before breakdown or further damage occurs.

What is Thermography?

Nearly everything heats up before it breaks down

A loose electrical connection.A bearing in a motor.

Your temperature rises if you are ill.



6/12

Common Marine Thermography Application Areas

1. Electrical Systems

2. Rotating Mechanical Equipment

3. SOLAS Compliance



7/12

Electrical Systems

Types of equipment commonly surveyed:

Main & Emergency SwitchboardsControl PanelsFuse Boards

Distribution BoardsBattery Systems & ChargersBridge Controls



8/12

Rotating Mechanical Equipment

Types of Anomalies Highlighted

Bearing Failure / DamageCoupling Failure / DamageMisalignments

Internal Winding FaultsLoose or Over Tight Belts



9/12

SOLAS Compliance

SOLAS Ch.11-2, Regulation 15.2.10 States That:

All surfaces above 220C are to be insulated or otherwiseprotected in order to avoid ignition of flammable fluids.



10/12

Common Misconceptions & The Need to Train

Things we hear regularly:

You can see through panelsIt doesnt have to be done liveWe cant get our camera to do that

08:00 I dont see the point in this12:00 I wish we had done this earlier!

The Same..But Different



11/12

How Everyday Thermography Affects The Bottom Line

Cost Avoidance:

Electrical Burnouts & Capital Replacement CostsOnly Insulate / Protect Localised AreasSpeed up Fault Finding

Late Arrival / Departure

Lower Insurance Premiums

Additional Benefits.
