Internal Pipe Inspection Services

MCDI has the equipment and expertise to internally inspect smaller pipes of 2" diameter and larger with either our robotic crawler camera system or push camera system. Large diameter pipes can be inspected via manned penetration or by our remotely operated vehicle (ROV).

Pipeline Inspection Services

MCDI can provide qualified dive crews to inspect areas of exposure and perform a visual and/or tactile inspection of any exposed portions of the pipe and its coating.  MCDI can also provide an extensive pipeline inspection report including drawings and hydrographic soundings encountered. Any underwater video footage obtained during the inspection can also be provided to the client.

For inspection and repair work on DOT regulated pipelines, MCDI DOT-OQ personnel are certified through the National Center for Construction Education and Research (NCCER). Additionally, MCDI meets all required National Compliance Management Service (NCMS)-DOT-PHMSA regulations.

Pipeline Cleaning Services

MDCI can clean pipelines and other structures with our trailer-mounted O’Brien water jetter, which is rated to pump up to 40 gallons per minute at 2,000 psi.
