Underwater Inspections

Connors Diving Services has a full range of underwater inspection and survey equipment for the provision of proficient and thorough inspections covering a wide range of materials and environments. We are certified to perform class surveys for Lloyd’s Register, Det Norske Veritas (DNV), Germanisher Lloyd (GL) and American Bureau of Shipping (ABS). Copies of these certificates can be made available upon request. Equipment and expertise in this area include the following:

  • Ultra Sonic Thickness
    With the most modern, programmable wall thickness meter we can determine wall thickness on flat, curved and/or rear-eroded surfaces for most materials. Employing a pulse-echo method with transmit time evaluation, we can accurately determine wall thickness to a 0.1 mm tolerance on surface or underwater. Early detection of corroded and eroded materials can aid in failure prevention and minimize potential costs.
  • Magnetic Particle Inspection
    Our trained personnel can assess structural integrity and weld condition through the use of fluorescent magnetic ink and accompanying UV lamp instruments to reveal defects in ferromagnetic surfaces.
  • Potentiometer
    Our corrosion control monitor is one of the most accurate methods of detecting levels of corrosion or stray currents. Accurate to 1/1000th of a volt, we can determine the exact potential present to accurately fit catholic protection, which will maintain an equal balance for the type of immersed material.
  • Remotely Operated Vehicles (ROV)
    With three ROV's at your disposal, we offer 1000’ depth accessibility to assists in locating, identifying and assessing through the eyes of either mounted color or black and white cameras with pan and tilt and auto iris features.
  • Closed Circuit Video
    By employing our CCTV system, the client is capable of viewing the inspected area as the inspection is being performed. Coupled with the underwater communications, this provides the best possible visual assessment, as it exists at the time of the survey. With our “pinhole” cameras and powerful lighting, we are able to see what the naked eye cannot.
  • Underwater Color Video
    With our hand held color video, the customer has the benefit of diver audio describing position, location and areas of interest or concern removing question of angles and related definitions. Still photos can be obtained from the videos and digitized, allowing the customer to have a hard copy of any points of interest. All videos may be accompanied with a written report upon request.
  • Digital Photography
    Digital pictures can be taken underwater, allowing the customer to immediately view the image. These pictures can be printed, saved or even e-mailed allowing for much quicker results than previous 35mm. Photos are taken using a Sony DCS-F707 encased in an amphibico housing. Pictures can be taken at 5.0-mega-pixel resolution, allowing for extremely high definition images and the ability to zoom in on specific areas without sacrificing quality. Night vision pictures are also an option in conditions were flash photography is not wanted.
