Infrared (IR) Thermography is a widely recognised and effective non-destructive inspection technique for checking electrical and mechanical systems. Infrared thermographic cameras are used to detect thermal energy and convert to visible images. The images can then be analysed by a thermographer who can identify any problem areas.

Used in conjunction with the range of Mimic Condition Monitoring techniques, such as vibration and lubricating oil analysis, thermographic images add an extra dimension of information to the state of health of the engineering system on board.

JF Mimic aim to reduce the number of costly breakdowns and to prevent damage by detecting equipment failure in its early stages by performing thermographic surveys on electrical and mechanical systems.

JF Mimic’s surveys allow fast and secure inspections in line with the tight loading, unloading and delivery times which currently rule the maritime trade.

Electrical Inspections

An overheating fuse can be caused by an overloaded circuit, phase imbalance or an undersized fuse

Thermal Imaging is a very efficient and practical inspection tool for determining the condition of plant and equipment by surface temperature. Electrical systems are a prime example where deterioration will show as a temperature difference.

A typical thermographic survey conducted by our engineers for electrical systems includes but not limited to; distribution boards, switchgear, control panels, motors and starters, fuse panels, LV/MV/HV equipment. The types of defects highlighted in an electrical inspection includes: overloading, loose/poor connections, insulation breakdown.

Mechanical Inspections

In the marine environment thermographic imaging can also include mechanical systems as the cause of thermal anomalies. Thermographic imaging of running machinery can play an important part in testing and assessment.

Overheating pump bearings can be caused by bearing wear or misalignment

Misaligned shafts, dry bearings, loose couplings...etc all exert adverse loads on the machinery in question, which in turn generates localised heat - which can be detected and quantified.

JFM’s Thermographic Engineers use FLIR Systems Ltd infrared cameras. FLIR Systems is the world leader in the design and manufacturing of infrared cameras.

The analysis, advice and recommendations of JFM’s experienced Thermographic Engineers are endorsed by the training standards of the British Institute of Non Destructive Testing (BINDT)

Fire Prevention and SOLAS Compliance

The hazardous and volatile environment of an engine room can harbour many potential fire hazards including machinery failure or possibly a ruptured fuel or oil pipe spraying onto adjacent hot surfaces. Engine room fires will have severe and costly consequences for the ship and its cargo, its crew and last but not least for the shipping company.

As a ship owner and operator we fully endorse the rules and requirements of the SOLAS Regulations aimed at minimising the risk of fire and a detailed thermographic survey carried out by our experienced engineers is an excellent method to ensure compliance of SOLAS Reg.11-2/15.2.10;

“All surfaces with temperatures above 220° C which may be impinged as a result of a fuel system failure shall be properly insulated.”

Thermographic inspections with an infrared camera will instantly show the degradation of insulation and shielding surfaces on potentially hot systems and structures including; turbo chargers, exhaust systems, steam systems, heat exchangers, main engines and boiler systems.
