Highlight Project – Solar Energy Generating Systems

Hennigan Engineering was recently awarded a contract to perform services for NextEra Energy at their “Solar Energy Generating Systems” (SEGS) Solar Energy SEGS located in the Mojave Desert of California.  The SEGS facility is the second largest solar thermal energy generating system in the world.

The facility is comprised of nine solar power plants that have 354 MW net (394 MW gross) capacity. This is enough power to service 232,500 homes during the day at peak power.

Solar Energy SEGS

This displaces approximately 3,800 tons of pollution per year that would have been produced if the electricity had bееn provided by fossil fuels.

The facilities have a total of 936,384 mirrors and cover more than 1,600 acres (647.5 ha). Lined up, the parabolic mirrors would extend over 229 miles (369 km). The installation uses parabolic trough, solar thermal technology along with natural gas to generate electricity.  

About 90% of the electricity is produced by the sunlight.  Natural gas is only used when the solar power is insufficient to meet the demand from Southern California Edison, the distributor of power in southern California.

Heat exchange/transfer efficiency is critical. The sunlight reflects off the mirrors and is directed to a central tube filled with synthetic oil, which heats to over 400 °C (750 °F). The reflected light focused at the central tube is as much as 80 times more intense than the ordinary sunlight. The synthetic oil transfers its heat to water, which boils and drives the Rankine cycle steam turbine, thereby generating electricity. Synthetic oil is used to carry the heat (instead of water) to keep the pressure within manageable parameters.

Hennigan Engineering will mobilize to the site in January 2018 to perform critical heat exchanger tube cleaning services in order to maximize system efficiency and power output.

Hennigan Engineering Helping to Bring Drinking Water to Puerto Rico

After this year’s devastating hurricane season,  Hennigan Engineering wanted to help those most in need.  Our friends in Puerto Rico were stuck with a critical lack of clean drinking water following the storm, and the damage to the infrastructure persists.  Hennigan Engineering partnered with SIFAT.org (Servants in Faith and Technology) to deliver enough Sawyer Water Filtration Systems to produce 300 million gallons of drinking water within weeks of the crisis.

Hennigan Engineering has enjoyed a long-lasting relationship with the people of Puerto Rico via our business with PREPA (Puerto Rico Electric Power Authority) and our local business associates at Environics Group, San Juan, P.R.  We wish for the quickest return to normalcy for the good people of Puerto Rico.   If you would like to join us in supporting the efforts there, please log onto the link here to SIFAT and donate today.

Hydrolasing Pipelines

Pipeline Before & After Hydrolasing

Hennigan Engineering recently hydrolase-cleaned 400 ‘ of critical Power Plant Cooling Water Piping which greatly improved our client’s flow and thereby the plant’s performance.

A part of our client’s email reads:

Thanks to the Hennigan folks for working with us to get it done correctly and safely.  I know it was a difficult task to take on, but well worth the end result.  I believe, with some flow balancing, this will get us plenty of much needed flow margin.  “

 

Pipeline Condition Assessment

Job Location: National Park Service – Fort Jay, Governor’s Island, NY

Hennigan Engineering was retained to perform a Utility Pipeline Infrastructure Condition Assessment for the National Park Service on Governor’s Island in New York Harbor.  Our client for this project is a global engineering company that provides consulting, design, construction, and operations services for corporations, and federal, state and local governments around the world.  The firm ranks in the top 3 of  Engineering News- 2016 list of Top 500 Design Firms.

Fort Jay waGovenors Island NYs originally constructed CIRCA 1776, making it approximately 240 years old.  Its original purpose was the defense of New York City during the American Revolution.  Fort Jay has undergone many renovations and improvements over the years.  The facility is currently a Federal asset in the charge of the National Park Service.  The current plan for this property is to prepare for asset rehabilitation to showcase and accommodate exhibits, research, and programs related to the harbor, administrative offices and in residence programs for National Park Service.

Pipeline Video Inspection Govenors Island NY

The stormwater and sanitary collection and conveyance systems are ancient.  Most are more than 100 years old and constructed of brick and mortar or clay pipe.  The condition, location, flow path and connections joining storm and sanitary flows were largely unknown.  In order to design and implement site improvements for the immediate future of Fort Jay, these utilities needed to be located and assessed.

Over a one-week period; Hennigan Engineering was successfully able to locate, identify and assess the condition of all storm and sanitary systems serving the fort.  In addition, we were able to develop a detailed, map of these systems.  This was done by utilizing state-of-the-art CCTV equipment, radio detection equipment and dye-testing techniques.    Numerous underground structures were found that were not shown on any existing plans of the site.  In addition, we performed a hydrant flow test and developed the calculations necessary for the design of fire suppression systems for the buildings.

Utility Assessment

 

Upon completion of the work, Hennigan Engineering developed a detailed report that included down-pipe snapshots taken from the video and other graphics as necessary for the owner to understand the status of their storm and sewer system.  This included our recommendations to effect repairs and maintenance of the system in the future in support of the impending site rehabilitation.

The owner and our client have reported that they intend to re-engage Hennigan Engineering to execute the recommendations made in our Fort Jay report and also; to repeat this performance at Castle Williams on Governors Island in 2017.

 

Specialized Concrete Hydro Demolition

Hennigan responds to customer’s request to remove 7 inches of overhead concrete from an intake bay under critical path schedule.  Hennigan completes 1st bay 7 days ahead of schedule, safely and under budget.

Hennigan Engineering Co., Inc. was called in to perform a concrete demolition operation at a Nuclear Power Plant after 21 days of jackhammering by another contractor failed to achieve the specified results.  The failed pneumatic demolition effort during this outage caused a work stoppage and steel reinforcing beams needing to be installed to allow the plant to operate an ICW pump bay.

Because of live electrical lines and numerous pipe interferences and other obstructions in the work area, robotic concrete demolition technologies could not be used.  Hennigan was hired to design a concrete removal system to remove overhead concrete material and allow the plant to make the necessary structural repairs to satisfy both the Nuclear Plant and NRC.

Hennigan Engineering designed a remote cleaning system that allowed individual tool operators the ability to hand control the path of the water jets, 40,000 psi was used to remove the concrete at high rates of production.

Before Hydro Demoliiton

In  addition to the ceiling removal, Hennigan personnel removed a thrust beam that housed pump bracing.

Hennigan Engineering was able to map out electrical lines using Ground Penetrating Radar (GPR) and safely hydrolase concrete to the desired depth without incident.
