Infra-red thermography is a widely accepted PPM technology that can be applied to electrical
and mechanical systems found in the Marine Industry.
In additional to saving money and increasing uptime, thermography can play a crucial function in
maintaining the safety and reliability of marine facilities where system failure could lead to catastrophic
loss of vessel or its crew.

Oil leakage hitting hot spots on engines is the major cause of engine-room fires onboard ship. According
to casualty statistics more than 60% of all engine room fires have been initiated by a hot spot.
Most lubrication, hydraulic and fuel oils have an autoignition point above 250o C. If a liquid hits a surface
hotter than its autoignition temperature the liquid may ignite spontaneously. Any such hot spot is
an immediate hazard in case of oil leakage.

Ship's
batteries are often left for long periods on float charge, with little
maintenance. Battery condition is not always obvious from SG and voltage
readings. Internal resistance (Ri) increases with age and is inversely
proportional to battery capacity, therefore being able to read Ri gives a good
indication of battery condition. Generally, batteries should be replaced when Ri
increases by 30-40%.

Thermographic
imaging of running machinery can play an important part in
condition monitoring and assessment. Mis-aligned shafts, dry
bearings, loose couplings...etc all exert adverse loads in
the machinery in question, which in turn generates localised
heat - which can be detected and quantified.
