and "A scan" equipment along with full weld inspection using angle beam probes.
MAGNETIC PARTICLE INSPECTION (MPI)
M.P.I can be provided for surface crack detection using dedicated equipment employing direct and indirect magnetisation systems. Surface preparation of the test pieces is also part of the service and ranges from high pressure water blasted surfaces, abrasive grit blast or machined finishes. Personnel hold both national and international inspection qualifications with an extensive background in offshore and onshore surveys of structures and components.
General inspection tasks are supported by High Resolution Colour Video equipment which utilises the latest digital image enhancement technology and produces close up pictures of such high quality, engineers are continually amazed with the final results.
These images can then be stored on conventional V.H.S. cassette, Super V.H.S. DVD or Digital Hi 8 format for improved picture quality. Real time imaging on the surface enables engineering staff to direct the survey and concentrate on the areas which are of most importance to the project.
Still photography systems using both 35 mm and digital underwater cameras provide a range of photographic presentations including photo-mosaics, overall wide angle, and macro photography. Detailed inspection reports and CAD drawings are provided.
