Video Inspection Services saves customer costly Hospital Shut-down

Boston, MA – June, 2015 Video Inspection Services

Hennigan Engineering Company, Inc. was retained by a National Design/Build Contractor to perform Emergency Response Video Inspection and blockage removal from a municipal pipeline linked to their construction of an addition to an active hospital in downtown Boston, Massachusetts.  The blockage came on unexpectedly during construction and was sufficient to cause back-up into active/occupied spaces within the hospital.

Two other contractors failed to solve the problem after several days of trying, then Hennigan Engineering was called into the situation.  The affected wings of the hospital were in imminent risk of being shut-down by local Public Health officials as well as the City’s Engineering Department.  The municipal pipe was approximately 15 ft. below two heavily travelled city streets.

If Hennigan Engineering was not successful in locating and removing the blockage, our client would have been mandated to excavate the municipal pipe and replace approximately 150 ft. of this 24 in. pipe.  This would have been a significantly detrimental direct cost and project delay cost for our client.

What two other pipeline service contractors failed to achieve over the course of three days; Hennigan Engineering’s specialized crew and equipment achieved in less than one day.  The blockage was found to be comprised of construction debris including PVC pipe segments and whole bricks.  The debris was removed without shut-down of the affected hospital wing or further construction delays.

It is this type of consistently cost-effective and reliable performance by Hennigan Engineering that continues to set the firm above all others.

Extending Condenser Tube Life

Hennigan Engineering was recently selected to participate in an in-depth condenser cleaning and refurbishment project to extend the life expectancy of condenser tubes at a US nuclear power station.  The project involved 20,000 PSI hydrolase cleaning of condenser tubes, 100% Eddy Current Inspection of condenser tubes, down tube coating of condenser tubes that failed minimum through wall criteria, installation of new tube sheet coatings and Helium Leak Detection of condenser tubes and tube sheets prior to the waterboxes being placed back into service.

Hennigan Engineering personnel performed 20,000 PSI hydrolase cleaning to remove MIC corrosion, bio fouling, manganese and calcium scaling, as well as, helium leak detection services as part of the over all solutions while the plant maintained on-line status, with only a single box out of service at any given time.

President Timothy R. Hennigan, Jr., stated that Hennigan Engineering is proud to have been a part of the team.  Hennigan Engineering performed the work to the highest safety standards and efficiently completed our part to meet the customer’s rigorous schedule for the performance of all associated tasks.
