Underground Power Distribution from Nuclear Power Station

The project, undertaken by the Florida Power & Light Company in Port St. Lucie, Florida (USA), involved the design, installation and startup of 13.65-mile long, parallel, 230 kV, underground power transmission circuits, starting at the St. Lucie Nuclear Power Plant Switchyard and terminating at the Turnpike Substation. The circuits will provide an additional way to move power between the plant and the FP&L electric grid. According to Mears Group, “undergrounding these transmission lines helps safeguard the operation of the nuclear plant and ensures the delivery of reliable electric service to FP&L’s 4.8 million customers in the face of severe weather.”

Jet Pump for HDD and Long-Distance Pipe Jacking

 Herrenknecht AG (Germany) was recognized for its development of the Herrenknecht Downhole Jet Pump (DHJP); this jet pump system absorbs cuttings from the bottom of the borehole and pumps them via the drill string to the exit side to surface. Due to the higher velocity of the discharge fluid, the system can handle a maximum cutting size of up to 1 ½” and therefore allows relatively large cuttings compared to conventional HDD.
