Inspection & NDT
Regular inspection saves money and improves safety by helping to highlight maintenance opportunities before they develop into possible incidents. It is necessary to ensure that all equipment is in good repair. This is where an active and well-designed inspection program fits in. Seaspec Marine Services conduct a wide range of inspection services, for example:
Ultrasonic uses high frequency sound energy to examine equipment and make measurements for flaw detection. It is frequently used in the detection of material thickness, weld discontinuities or defects, cracking on shafts and lamination checks for corrosion mapping.
Vacuum box testing is a method used to detect leaks in welds and to confirm the weld quality. The vacuum box technique detects leaks in a pressure boundary that cannot be directly pressurised such as welds, weld seams, and other components in welded materials.
We possess a variety of vacuum boxes that are available for the inspection of butt or lap welds, corner welds, and mini size vacuum boxes for small and difficult areas.
Dye Penetrant Inspection
Dye penetrant inspection, also called liquid penetrant inspection, is a widely applied inspection method used to detect surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).
Liquid penetrant exams check for material flaws open to the surface by flowing a very thin liquid into the flaw and then drawing the liquid out with a chalk-like developer. Welds are the most common item inspected, but plate, bars, pipes, castings, and forgings are also commonly inspected using liquid penetrant examination.
Corrosion is the degradation of metal usually resulting from interaction with the environment around it. Over time, corrosion will gradually reduce the original material thickness reducing the strength.Corrosion can lead to failures, expensive repairs, and reduced efficiency. Strategic corrosion inspection and monitoring can improve asset management and life cycle assessment and optimize operational budgets.
