Dorchester Maritime Limited (DML) is a ship management company based in the Isle of Man. DML is a member of the Schulte Group - a multi-faceted organisation involved in many shipping-related activities. The group owns over 90 vessels, and encompasses six ship management companies. These are responsible for the management of over 400 vessels (including 80 gas vessels), and has wholly-owned crew recruitment agencies in Poland, Myanmar, Sierra Leone, Philippines, India, Latvia, Estonia and Australia.
DML manages over 120 vessels, including LNG/LPG Carrier, FPSO/FSO, Tankers (Crude, Product and Chemicals). As part of their management package, they considered utilising infrared scanning. In the past, contractors had occasionally carried out thermography surveys to great effect. But with the cost of ownership of cameras coming down, approval was sought to purchase a couple of Flir InfraCAMs. DML are also using vibration / shock pulse sensing technology as an integral part of their maintenance strategy to reduce equipment downtime and plan overhauls.
Tommy Haljmas comments, "I used the Flir camera for the first time onboard Nav Venus last week. Very easy to use, and we identified several 'hot spots' over the two days we used it, and documented several other items/ systems onboard to create a database with examples of usage."
"In addition to electrical cables and connections, we used it to check for hot areas around T/C's, as well as to verify temperature readings in HFO pipes before engines and to find steam leaks. I found it useful to verify temperatures in systems, and track leaking valves as well as electrical connections."

Tommy concludes with the following advice, primarily aimed at horse-riding wives (or husbands)...
"When I got home from Nav Venus, my wife could not decide if to go riding or not. Obviously, I wanted her to stay home and make dinner. Her horse had an infection in her left hind leg for, but it seemed better. I used the Flir camera just as a test, and we could clearly see the area of the infection and it was slightly warmer (i.e. the infection was not 100% gone). Based on this, my wife decided to let her horse rest for another few days."
Many thanks for this contribution, Tommy!
