News Updates

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.

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 system 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 Engineering 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.

In January 2014 Hennigan Engineering was contracted by a large Southern Power Company to design a cleaning system and perform a cleaning for Flue Gas Scrubber Tubes.  The Customer had previously hired three different vendors who had failed to clean more than 700 tubes that contained a extremely hard scale material.  Hennigan Engineering performed various nozzle design and testing prior to presenting a solution to the customer.  Hennigan was hired to perform the work and completed the project clueing the entire 4000 tubes including 700 plugged tubes that previously vendors had failed to clean.  Hennigan completed the project within the customers schedule and within budget.

The project was successful to the customer to the point that Hennigan was Sole Sourced for the scrubber cleaning in 2015.

Hennigan Engineering is recognized as an industry leader in Condenser Tube Cleaning, Heat Exchanger Tube Cleaning, Speciality Concrete Hydrodemolition, Hydroblasting, Hydrolasing, Video Inspection Services, Helium Leak Testing, Air-in Leakage Testing, Water Intrusion Repair, Coatings Removal and Application.

Claudia Hennigan (CEO) of Hennigan Engineering is pleased to announce that Hennigan has received WBENC certification for Women Owned Business.  While this certification does not effect the excellent work ethic and reputation that Hennigan has built over the 47 years of business, it will allow our customers who have diversity programs to take advantage of the spending they are currently doing with Hennigan.  Hennigan performs hydroblasting, hydrolasing, condenser and heat exchanger tube cleaning, hydrodemolition, helium leak testing, video pipe inspection and an array of industrial cleaning services to the Nuclear and Fossil Power Industry as well as DOD and other customers.
