Hi everyone. I was going through some of my thermal images
from past surveys and found a few I thought you would all like to see and to show you how well this technology works for trouble shooting hulls, boat systems, and verifying that damage does or does not exist. I took these images
during several surveys of power and sailing vessels with a "Flir" brand "E50" infrared thermal imaging camera
. Here are a few:
This is a thermal image of a powerboat above. Using heat from the inside of the cabin
(causing thermal conduction) I was able to see the fiberglass
laminates and the deck
frame work to look for suspected damage.
This is what core
replacement look like in the deck
of a sailboat (the darker rectangular shape). The new core
was a PVC type core surrounded by the existing original Balsa wood core deck. It was unnoticeable on the bow deck until I turned the thermal imaging camera
This is a loose keel
during the bottom inspection
. This was a bolt on type keel
on a 1981 Irwin
. The keel bolts
were loose when inspected from the inside of the main salon
This is a thermal image of a large fuel tank
as seen through the aluminum
of the hull
. Notice the transverse frames as well.
This is moisture / wood deterioration behind a bulkhead on a Bertram Sportfish in the aft main salon
area near the window.
To most this technology is unknown. I also advise that anyone using the thermal imaging camera to scan your vessel or vessel's engine
be at least a level one certified thermographer. There is a science to it. Shadows and reflective objects can be mistaken for anomalies. The images also need to be properly tuned based on the environmental conditions at the time the thermal images are taken to have the ability to identify actual anomalies. If not properly tuned, the anomalies can hide within the image as some anomalies may only be a few degrees in difference in temperature.
