Thermal Imagers and Marine Inspections
Charles J. Hazouri
Level III Infraspection CIT, Certified Marine Surveyor
Inspection techniques such as infrared thermography, ultrasonic testing, and visual inspections using unmanned aerial vehicles (drones), have changed the face of marine inspections/surveys. Not so long ago, these technologies were unheard of and beyond the budget of many surveyors; however, recent advances in technology have made such test equipment quite affordable. Combined with greater public awareness, these tests are rapidly becoming an integral part of marine inspections / surveys. This article will focus on the application and benefits of infrared thermography as a tool for the marine surveyor.

Captured post-sunset under calm weather conditions, image shows a thermal pattern that is typical for insulations that readily absorb water. Taken by Randy Kiez, this thermal image was the 1st Place winner - Roof Category in the annual Image Contest held during the IR/INFO 2016 Conference.
