Infrared thermography is a technique to measure and spatially evaluate temperature patterns due to temperature differences. In recent times, Infrared (IR) thermography has become a powerful tool in various ﬁelds such as industrial investigations, environmental and military monitoring. It is used for law enforcement , and last not least, in the boating industry.
The boating community benefits from this technology in two main fields of application:
- Vessel hulls can be scanned in a quick and efficient manner in order to gain overview about invisible lurking problems. For that, the hull must be monitored in a state of “thermal imbalance”. If, after a thermography session, the surveyors suspects damages in the hull, then they may resort to detailed, but slow NDT investigation, like ultrasound investigation.
- The machinery, electrical installations and electronic systems of vessels are getting more complex over the years, and plumbing as well as heating/cooling equipment is nowadays the rule than the exception. Thermography is a fast and highly reliable method to establish where there is high temperature where it should not be, like with power cables with overload or cable connectors of high transition resistance and also where there is no temperature where expected.
With our FLIR thermal camera we can perform thermographic inspections on various equipment and on hulls.
Some inspections we regularly carry out, often in the context of pre-purchase surveys are the following:
- Water and moisture intrusions on hull and other areas,
- Structural defects,
- Engines, generators, gearboxes and their components,
- Potential electrical overloads,
- Joints and sections of electric lines such as circuit breakers, busses, etc.
- Heating and air conditioning units,
- Bearings, shafts, pulleys, etc.
- Leaks and blockings in plumbing.
Infrared thermography has the ability to identify problems before they grow and turn into serious issues. Regular IR thermography is common good practice for complex machinery like junction boxes and is a simple and effective prevention of fire damage.
