ACFM Inspection or Alternating current field Measurement Inspection
ACFM Inspection or Alternating Current Field Measurement Inspection is one of the best ways for the detection and sizing the length and depth defects on surface of metallic components and welds. Aries Marine and Engineering Services provide ACFM Inspection service for offshore platforms, rigs, ships and industrial applications.
The ACFM Inspection service by Aries Marine has significant benefits and cost savings as the inspection can be performed without the coatings being removed. Our ACFM service has been used extensively in off shore platform applications on piping and structural members.
ACFM Inspection works through paint and coatings and in a wide range of temperatures. The Alternating current field measurement probe induces a uniform alternating current in the area under test and detects the resulting current flow near to the surface.
ACFM inspections is used by Aries marine on multiple inspection jobs. One of the use of ACFM is inspection of the splash zone areas on the legs of offshore oil and gas platforms due to its ability to be used without the need to remove marine growth.
Major Advantages of ACFM Inspection by Aries Marine:
- ACFM is used for base material or welds on ferritic or non-ferritic metals
- ACFM can be performed on hot surfaces
- Minimal surface preparation
- Can be applied over paint and other coatings
- ACFM will work in underwater environments
- ACFM Inspection data can be stored and analysed offline
Alternating Current Field Measurement is used for:
- Detection and sizing of fatigue cracks
- Inspection of welds in offshore platforms and rigs
- Detection of cracks and corrosion in vessels
- Detection of cracks and corrosion of piping in oil and gas and petrochemical industries
- Inspection of drilling tools
At Aries Marine & Engineering Service latest Alternating Current Field Measurement (ACFM) inspection methods are available. This will help in deployment on many structures without removing coating or conventional access. Our ACFM technology can even be deployed at temperatures in excess of 500 degree Celsius, which means that inspections can be carried out outside of normal shut down periods.
