News Updates

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.

This displaces approximately 3,800 tons of pollution per year that would have been produced if the electricity had b??n 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.

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.

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.  “

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 wa

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.
