Inspection of the underwater parts of offshore platforms, subsea pipelines and other underwater structures is usually performed by divers. ACFM is one of the most widely used inspection techniques underwater beacause:

• It can be deployed without cleaning to bright metal
• It provides auditable, electronically stored results
• It can detect both size and surface breaking defects
• It is unaffected by material property changes at welds
• Results can be compared year on year
• It can be used in the dark.

ROVs are being used more and more often for inspection tasks, not only where depths are too great for a diver but also because of increasing health and safety concerns associated with the use of divers.

About ACFM:

ACFM is an electromagnetic technique for detecting and sizing surface breaking defects in metals.

ACFM is particularly suited for inspecting painted and/or welded structures.

TSC manufacture and sell inspection systems that use the patented ACFM technique. These systems allow operators to deploy non-contacting ACFM probes with only minimal cleaning requirements saving significant time and money.

A modern ACFM inspection system comprises a field-inducing probe with state-of-the-art low noise analogue electronics coupled with a built in control system and easy-to-use Microsoft Windows based analysis software.

Advantages of using ACFM systems from TSC include:

• Off-the-shelf products for numerous applications including portable, static and underwater deployment
• Experienced engineers and product development teams for bespoke ACFM systems
• ACFM products are accepted by leading Approval and Standards bodies
• First class training available for all ACFM products
• Certified ACFM inspection operators available if required.
