THREE NDT METHODS. ONE CERTIFIED TEAM.
OSM International runs three primary NDT methods: MT, PT, and VT. Our SNT-TC-1A Level II certified technicians deploy to any location in the Americas and Caribbean, and the inspection reports they produce are accepted by every major classification society, P&I club, and flag state administration.
Magnetic Particle Testing
Detection of surface and near-surface discontinuities in ferromagnetic materials. Highly sensitive for fatigue cracks, grinding cracks, and seam defects in crankshafts, shafts, and forgings.
Common applications
Crankshafts, connecting rods, propeller shafts, welds, forgings
Dye Penetrant Testing
Surface flaw detection for all non-porous materials including non-magnetic alloys, stainless steel, aluminum, and titanium. Highly sensitive visible or fluorescent dye methods available.
Common applications
Austenitic steel welds, aluminum castings, non-ferrous components
Visual Testing
Systematic visual examination by certified inspector using calibrated tools, mirrors, and borescopes. Required as the primary method on all inspection programs.
Common applications
Pre- and post-repair inspection, coating inspection, structural assessment

Our Certification
SNT-TC-1A LEVEL II
All OSM International NDT technicians hold ASNT SNT-TC-1A Level II certification in the inspection methods they perform. Certification records are available to clients and classification surveyors on request.
Common Inspection Applications
- Crankshaft journal crack detection after machining
- Weld inspection and post-weld heat treatment verification
- Propeller shaft surface crack detection
- Engine block and cylinder head inspection
- Pressure vessel and piping weld inspection
- Anchor chain link inspection
- Lifting equipment and mooring gear inspection

COMMON QUESTIONS
NDT INSPECTIONS: ANSWERED
What does SNT-TC-1A Level II mean?
SNT-TC-1A is the recommended practice published by the American Society for Non-Destructive Testing (ASNT) that establishes qualification and certification requirements for NDT personnel. Level II means the technician can independently set up and calibrate equipment, conduct inspections, interpret results, and prepare written reports. All OSM International NDT technicians are ASNT SNT-TC-1A Level II certified.
Which NDT methods does OSM International offer?
We provide three primary methods: MT (Magnetic Particle Testing) for surface and near-surface cracks in ferromagnetic materials; PT (Dye Penetrant Testing) for surface flaws in any non-porous material including stainless steel and aluminum; and VT (Visual Testing) as the baseline method on all inspection programs.
Are NDT inspection reports accepted by classification societies?
Yes. Our SNT-TC-1A Level II certified technicians produce fully documented inspection reports accepted by DNV, Lloyd's Register, ABS, Bureau Veritas, NK (ClassNK), RINA, and all IACS member societies. Reports include method-specific data, equipment calibration records, indication mapping, and technician certification references.
How long does an onsite NDT inspection take?
Most inspection scopes are completed in a single visit: from a few hours for targeted weld or component checks to a couple of days for a full survey across multiple engines or assets. We mobilize within 24 to 48 hours anywhere in the Americas and Caribbean.
When should NDT be performed on a crankshaft or propeller shaft?
NDT should be performed after any machining or repair operation (to confirm no grinding cracks), during class renewal and special surveys, after a suspected overload or grounding event, and whenever abnormal vibration or bearing wear points to possible fatigue damage. OSM International routinely combines NDT inspection with onsite machining, completing both in a single mobilization.
