Infrared Thermography, thermal imaging, or thermal video, is a type of infrared imaging science. Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 900–14,000 nanometers or 0.9–14 µm) and produce images of that radiation.

Since infrared radiation is emitted by all objects based on their temperatures, according to the black body radiation law, thermography makes it possible to “see” one’s environment with or without visible illumination..

With thermal imaging systems things that cannot be seen clearly with naked eyes, can be easily seen. For seafarers Thermal Imaging Systems is very useful. The look and the method to operate of a modern thermographic camera and a camcorder is often similar. Enabling the user to see in the infrared spectrum is a function so useful that ability to record their output is often optional

Advantages of Thermography:-

It shows a visual picture so that can help compare temperatures over a large area

It is capable of catching moving targets in real time

Able to find deteriorating components prior to failure

Measurement in areas inaccessible or hazardous for other methods

It is a non-destructive test method

Make easier to find defects in shafts and other metal parts

Here are few advantages of having a Thermal Imaging System on board:-

Safe navigation at night

Searching for the man overboard

Damaged hull inspection

Identifying moisture accumulation in FRP/core laminate

Measuring skin temperatures of storage tanks & boilers on the vessel

Identifying loose and corroded electrical connections and overheating of electrical cables.
