Electrical IR Survey on Siesmic Mapping Vessel

Our company continues to grow strongly in the electrical thermal imaging industry in New Zealand. We have imaged 1000’s of switchboards across NZ, namely in the agricultural, food production, cold storage, shipping and offshore oil sectors.

We were recently hired to complete the thermographic survey of a large vessel while in the process of siesmic mapping of the ocean floor off the east coast of the South Island, NZ in search for potential oil fields. For optimal results, all infrared surveys should be carried out under maximum load where possible, and in this situation the ship was in transit at the time of inspection. This also allows the ships engineers/electricians to switch over to back up systems so all associated electronics can be accurately infrared imaged during the same survey.

We are an experienced thermography company in NZ, qualified for infrared inspections on Switchboards and Mechanical Components in all types of facilities.

Here is a typical list of components we apply thermal imaging surveys to on ships, and all onshore operations:

  • Main Engines
  • Generators
  • Main Switchboards
  • Emergency Switch Gear
  • Main Propulsion Units
  • MCC Boards
  • Motor Junction Boxes
  • We carry out thermal imaging of all Distribution Boards, such as 24V, 230V, 400V, 440V… right up to 11KV and everything in between.
  • Infrared imaging of Transformers, Compressors, Automation, Motors, Propulsion Drives, Cabling etc.

If you are looking for a reliable infrared company in NZ with an excellent track record for providing prompt service at short notice, along with compliant thermal imaging reports accepted by insurance companies who now require AS/NZS 3019:2007 (electronic installations – Periodic Verification) standards, then call us today to discuss your project and a free quote over the phone based on requirements.

We are certified thermographers with current medicals, HUET, BOSIET and constantly updated infrared cameras and technology. Call today to find out more.

Thermographic Survey of Electrical Systems – NZ

Here is exactly why a regular thermographic survey of company electrical systems is so important.

I inspect switchboards for many different private, commercial and insurance companies right across NZ, but the latest infrared electrical inspection in particular was quite interesting… for all the wrong reasons (In my opinion).

When you have a 24/7 operation, a thermal imaging survey every 6 months should be strictly enforced… not every 9 or 12 months. Recently, I was called out to an oil rig that had just experienced a fire in one of the main switchboard rooms nine months after the first thermographic inspection was carried out. If this company had maintained a strict policy for every 6 months, then this hot spot/fire hazard would have been picked up well in advance. To make matters worse, it was at 1:00am in the morning when the alarm went off. The crew of 40+ workers woke up to a fire on a ship full of oil. Not good. Put yourself in that position!

Upon the re-inspection of the surrounding switchboards in the same electronics room, I found another huge hot spot caused by a loose connection on the back of a sea water injection pump. The temperature at the connection was 167 degress! Here’s the photo…

This was a large offshore operation, so it was easy enough to shut this pump down and switch to the back up pump. It didn’t end there…

Next… I was thermal imaging a lighting panel in the engine room, and suddenly a glowing 92 degrees hot spot was coming off a 20amp breaker. Further testing showed 27 amps running through. It turns out the breaker and cables were under rated. One fire and two potential fires found within 3 weeks… this is not a record to brag about… but it can happen to any company who turns a blind eye to the importance of electrical system faults.

Remember, it only takes one hidden loose connection to potentially ‘bring the house down’. This is why some insurance companies now require thermal imaging prior to issuing a policy.

If you are considering a thermal imaging thermographic inspection, then now is the time. As the above company recently found out, it can turn out to be very expensive if you just ‘hold off’ for a few weeks or months… or not at all.  More electrical fault photos here

Infrared Thermography Inspection of Electrical Systems

Infrared thermography is a fast way to determine electrical faults, no matter what the complexity of the component is.

Recently I conducted a complete thermal imaging electrical inspection on an offshore oil rig. You can only imagine how important it is to prevent any type fire breaking out on a ship full of oil! The main benefit of electrical thermography is that the infrared camera can detect hot spots (and alot more) in an instant… the human eye will not see any of these anomalies in most cases.

No matter how switched on your on-site electrician or maintenance officer is, they simply won’t see what infrared can see… it’s impossible. In the case of this particular job, the thermography inspection yeilded 18 faults. Here is an example of just one electrical fault I found on board…
