The right method.
A traceable finding.
Inspection is useful when its scope, technique and limitations are understood. NDT and dimensional evaluation form part of the assessment, not a substitute for the complete technical picture.
Inspection with context.
OSM presents MT and PT capability under an employer SNT-TC-1A written practice. Personnel qualification, procedure requirements and inspection coverage should be confirmed for the specific assignment.
Magnetic particle inspection (MT)
Considered where the material, geometry, expected indications and access are suitable for the method. The agreed procedure and inspection conditions govern the work.
Liquid penetrant inspection (PT)
Considered for suitable surface inspection applications. Surface preparation, technique and interpretation are part of the defined inspection scope.
Dimensional evaluation
Document component geometry and compare the measured condition with the available acceptance criteria. Record where the measurements were taken and any access limitations.
Where inspection is applied
Inspection applications include crankshafts, shafts, stern tubes, journals, coupling and flange components, engine and gearbox bores, liners, rods and welds.
Inspection supported by measurement
Dimensional verification, surface finish analysis, hardness measurement and OEM comparison support the condition assessment.
A useful inspection record.
- Component identification and the area examined.
- Applicable procedure, personnel and equipment records.
- Relevant technique, inspection conditions and coverage.
- Reported indications, measurements and limitations.
- Acceptance criteria or a clear statement that further review is needed.
A documented basis for review
The inspection record supports discussion of the findings and the recommended repair strategy. Dimensional reports, wear measurements and supporting inspection records form part of the documented work.
No single inspection method establishes every aspect of component integrity. Additional testing or specialist review may be needed. OSM does not advertise UT or VT certification, blanket class approval or guaranteed detection.
