Why Certified Infrared Surveys Are Essential for Yacht Safety

Anyone can buy an infrared camera — but knowing what the image actually tells you? That takes experience.

Take the thermal image below, for example. One phase termination is running noticeably hotter than the others during a switchboard inspection — something a casual scan might miss. This highlights how uneven loading can affect electrical connections.

Collecting thermal images is the easy part. Interpreting them correctly requires training in both thermography and electrical systems. Certified thermographers are taught to:

  • Evaluate temperature differences accurately
  • Consider loading conditions and environmental factors
  • Identify real issues versus misleading readings caused by reflective surfaces or ambient conditions

Why infrared surveys are essential on yachts:

  • Detect loose connections, overloaded components, or imbalanced phases before failures occur
  • Meet survey requirements for class societies such as Lloyd’s, DNV, and ABS
  • Provide detailed documentation for inspections, including load conditions, measured temperatures, and actionable recommendations

Switchboards, bus connections, and breaker terminations may only show meaningful thermal differences when carrying sufficient load. Without experience, it’s easy to misinterpret what appears in the image.

For vessels where reliability, safety, and class compliance matter, infrared inspections should be treated as a technical survey – not just a photo session.

How often are infrared surveys performed on your vessel? If it’s been a while, it might be time to schedule a certified inspection.
