The Darker areas of this Cold-Molded Hull are areas of Moisture Intrusion.
These Images Show the Resolution, Zoom, and Detail of the FLIR T640 used in our inspections.

Thermal Imaging, Thermography, Infrared (IR)
What is Thermal Imaging?
Thermal imaging is a unique tool that uses the infrared portion of the light spectrum that is invisible to the naked eye. Infrared (IR), Thermography, or Thermal scanning, as it is sometimes called, allows the user to see one’s environment with or without any visible illumination or light. All objects over absolute zero give off a certain amount of thermal radiation. Thermal imaging provides a way to observe temperature anomalies in any machine or object, living, natural, or manmade even in solids like wood, fiberglass, aluminum, and steel. Thermal imaging or thermography is used by multiple sectors such as law enforcement and security, military, firefighting, medicine, science research, air and sea navigation, and marine surveying. IR is especially useful for predictive/preventative maintenance, new construction, and post laminate/structural repairs. Thermal imaging cameras provide a nondestructive, environmentally friendly way to see temperature differentials in an object to verify such things as electrical and mechanical failures, structural design, delamination (disbanding), damage, voids, structural location, and to locate moisture intrusion.
I currently use the FLIR T640 and FLIR T440bx which have High Thermal Resolution (640 x 480 and 320 x 240) and the FLIR E6 and FLIR C2 Thermal Imagers (Infrared Cameras), Currently Calibrated with built in Digital Cameras, to give the best comparison shot(s) and reports to our clients.

Benefits of Thermal Imaging:
Thermal imaging has multiple beneficial uses across many industries. Since it is non-contact, the area being analyzed remains unadulterated and everyone remains safe during the inspection.
The 2D nature of the testing allows for thermographic profiles to be taken at one or MORE points in a single image.
Thermal imaging is also real time, fast, and significantly reduces the diagnostic time and final cost of any repair since it is not necessary to disassemble any components being tested. It can pinpoint problems exactly where they occur and even before they are evident to the naked eye.
My marine inspections/surveys can include engines, transmissions, tanks, electrical equipment, electronic devices, and hulls to determine if malfunctioning components, leaks, or disbonding/delamination may exist within the vessel.
Finally, using FLIR Tools +, my survey reports are clear, helpful, informative, and professional.
What or Where would you use Infrared Imaging?
1. Hull and Deck – Infrared (IR) Imaging can indicate anomalies consistent to water intrusion, voids and disbonding (delamination) within the fiberglass laminate or coring materials.
2. Carbon Fiber, Kevlar Composite – IR imaging is often used on exotic composite vessels due to conductive materials which render moisture meters ineffective. IR imaging can accurately pinpoint laminate deficiencies and moisture ingress points.
3. Engine and Generator – IR imaging can also be applied to motors as they are run during sea-trials. Excessive hot spots in the engine blocks, injector lines, exhaust leaks and cooling systems often reveal internal engine problems that could cause future failures.
4. Electric Systems – “Hot spots” here indicate faulty electrical connections, poor breakers and faults in wiring that could overheat and catch fire.
Below are some random example IR Images from recent inspections (Additional pics can be seen in Photo Gallery):
