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.

Hennigan Engineering is a Certified Women Owned Company that provides Condenser Tube Cleaning, Heat Exchanger Cleaning, Helium Leak Detection, Concrete Hydrodemolition, Hydroblasting Services, Video Pipe Inspection and Cleaning, Water Intrusion Repair and Specialty Coatings to a variety of customers.   For more information on Hennigan Engineering services please contact us at info@henniganengineering.com

 

Hennigan Engineering Completes Flue Gas Scrubber Cleaning 25% Ahead of Schedule

 

Hennigan Engineering has recently completed a significant flue gas scrubber cleaning project approximately 25% ahead of schedule. The project encompassed cleaning over 4000 tubes, 900 of which where plugged solid, a majority of which where unable to be cleaned by a previous contractor over 3 years prior.

Hennigan Engineering’s specialty nozzle design worked flawlessly and allowed the customer to gain valuable time in their outage schedule. Hennigan Engineering is a Women Owned Company and is an industry leader in condenser tube cleaning, heat exchanger tube cleaning, hydrolasing, concrete hydro demolition, condenser and heat exchanger tube leak detection, video inspection and water intrusion repair. For more information please contact Hennigan Engineering at 800-472-8484.

Hennigan Completes Groundwater Remediation System Project

Groundwater Remediation System Restoration Project at a U.S. Navy Site in West Virginia.

Allegany Ballistics Laboratory Project: 2014

Hennigan Engineering Company, Inc. was retained by a large Environmental Services firm to video inspect, assess condition and clean / restore the groundwater remediation system at the Allegany Ballistics Laboratory (ABL) in Rocket Center, West Virginia. The ABL is operated by the Alliant Techsystems, Inc. (ATK). The overall groundwater remediation system was constructed and is run by Tikigaq / AGVIQ with CH2M Hill under contract with AGVIQ for water treatment facility Operations & Maintenance.

The systemABL Vac was originally installed over 10 years ago and includes several thousand feet of subsurface pipe, about 40 groundwater extraction wells, a water treatment facility, a water storage tower and a discharge / overflow system into the Potomac River. The system is in place to “capture” groundwater, divert is flow away from the Potomac River, remove chlorinated solvents from the groundwater water and discharge the treated water back into the river. The project is unique in that the treated groundwater is used by the ATK’s steam plant and also supports the site’s fire suppression systems. It is a critical operation to the sites ability to function. The systems performance had degraded over the years and had reached the point where it could no longer provided groundwater capture and was minimally able to meet the demands of the steam plant.

Hennigan Engineering utilized both hydrolase and jet blast equipment that ranged from 2,500 to 20, 000 psi with specialized cleaning heads to restore the system. Video inspection equipment included specialized high resolution cameras for pipe sizes from 1-inch to 6-inches in diameter. In addition, radio detection equipment was deployed to pin-point the location of critical features of the subsurface pipe.

Hennigan Engineering successfully video inspected the pipe system then restored its performance to flow levels that had never been achieved in the past – even when the system was first installed. This was done with negligible disturbance to the operation of the steam plant or compromise of the sites fire suppression system.

Hennigan EVideo Inspect ABLngineering developed a detailed Engineering report documenting the work, the results of the work and developed a scheduled maintenance program for maintain the system in the future.

Moving forward; Hennigan Engineering will be working with the client to keep the restored system operating at peak performance.
