Integrating Infrared with Ultrasound and Vibrations analysis applications for Marine and Offshore Industry |
|||
Predictive Maintenance is the use Non-intrusive Technologies of Infrared Thermal Imaging, Ultrasound Detection & Vibration measurements. |
Thermal Imaging: With the Thermal Signature, we can see the Infrared Radiation which we can not see otherwise |
|||
What is infrared? |
||||
|
|
|||
What is Ultrasound? |
||||
|
Human range (16Hz to 18KHz) |
|||
Levels of Severity With ultra sound |
||||
Above baseline 20 dB 
|
||||
|
Mechanical Inspection |
||||
|
||||
Some problems that can be detected with Ultrasound, Infrared & Vibration |
||||
|
Making Motor Ready for Service
|
|||
COUPLINGS AND SHAFTS ALIGNMENT |
||||
|
||||
Increase machine Reliability with Infrared Technology |
||||
This could be catastrophic failure on a VLCC can cause fire in main switch board |
||||
A TYPICAL MOTOR / PUMP PROBLEM - EXAMPLE |
||||
 |
This photo is taken in a leading company tanker vessel and displaying as example. |
|||
|
A 250 kw motor inert gas fan in a vlcc operating with drive end bearing temperature of 93.3*c is going to cause damage to motor due to misalignment and overloading |
 |
|||
Cause and effect of failed steam traps |
||||
 |
||||
The partially blocked pipe is an example of surface temperature effects in a pipe line |
||||
 |
||||
Sample evaporator liquid refrigerant inlet and expanded gas outlet at the return headers for each coil |
||||
 |
Both above compressors connected to this defective evaporator coils. Loss of energy with 2 compressors running with minimum climate control effect |
|||
Main air compressor high pressure suction valves one valve is leaking badly other valve is chocked with carbon trouble- energy loss/ damage to valves, carbonisation in inter and after coolers and reduced efficiency |
||||
 |
||||
Marine Propulsion Gear box showing high bearing temperatures The Gear box drive end bearing showing 85.4*C where the Lube oil temperature at the cooler inlet 48*c indicating trouble at at the bearing condition. |
 |
|||
A diesel generator alternator showing high temperatures can cause damages loss of alternator life due to excess temperatures |
||||
|
||||
Main start Air compressor onboard running very hot with LP discharge inlet to inter cooler about 194.2*C reduce the efficiency, long running hours and damage to many components like valves, coking in inter after coolers etc., |
||||
 |
||||
Leaking Boiler Relief valve This is not only dangerous but very costly in Steam production. This must be corrected at the earliest opportunity. |
||||
 |
||||
Pumps and hydraulics |
||||
 |
||||
Bearing Inspection Increase your Equipment Reliability with Ultrasound Technology |
||||
|
 |
|||
Vibrations of machinery |
||||
|
The ISO standards for the machinery vibration values limits |
 |
|||
Using FFT analysis for defects |
