Our thermal imaging surveyors follow the professional code of conduct as set by the International Institute of Marine Surveying.

Our surveys are undertaken by qualified thermographers to condition monitor vessel equipment, for pre-voyage and voyage needs in compliance with recommendations stated in the Maritime and Coastguard Agency (MCA) on Electrical Equipment and Installations, the International Association of Classification Society (IACS), Maintenance & Inspection of Electrical Equipment on the Ship #57.5 and #35 the International Maritime Organisation (IMO) for engine room hot-spot detection and fire prevention.

Infrared thermography is also highlighted by Lloyds Register in Guideline for ship owners and managers: Condition Monitoring of Marine Machinery. Our Marine Thermographic Surveys will help find:

  • Corroded & loose electrical terminations as per MCA: Electrical Equipment and Installations Part
  • Overloaded wiring in conduit running behind panelling.
  • Inductance heating at steel supports and cabling in strong electro-magnetic fields.
  • Failing electrical equipment in switchboards, un-balanced loading, loose electrical ferrules.
  • Electric motor issues relating to rotor or stator motor windings, (note: a 10°C rise above motor ratings cuts a motors' life by half)
  • Degraded piping and vessel insulation issues causing energy loss and heightened fire risk
  • Hot-spot surface temperatures over 220° C in engine rooms that will ignite fuel oil mists as stipulated under SOLAS and guidance notes as published in the DNV technical paper: Hot Surfaces in Engine Rooms.
  • Locate thermal bridging between engine bay and bulkheads
  • Locate blocked heat exchangers, cooling radiators and oil line blockages
  • Locate Pipe thinning and internal scaling problems in process piping
  • Locate inactive steam trap systems and passing valves.
  • Loose flange bolts in process piping.
  • Locate overheating pump bearings, machinery shaft misalignment and belt alignment issues
  • Discover structural alterations to a vessel hull
  • Locate delamination in fibreglass hulls and other composite materials

We also retro-fit Lloyds, ABS and DNV approved infrared inspection windows to switchboards, thruster terminal box covers, transformer housings and engine generator inspection hatches; for safe infrared and routine visual inspections without the need to open or shut off energized equipment, eliminating arc flash potential upon opening equipment.

At Geo Therm Ltd we have a duty of care to report on extreme thermal anomalies within critical electrical and mechanical systems, that could adversely affect your voyage. In short, our hot-spot Thermographic Surveys will dramatically improve your sea-going risk management.
