RECON was contracted to the project by the prime contractor, Chicago Bridge and Iron Works (CB&I ), whose administration and executive offices are located in The Woodlands, Texas. The owner of the project was Southern Nuclear, based in Birmingham, Alabama.
The project consisted of the construction of a raw water intake structure to supply a water source to the new cooling towers. Due to the depths, various soil layers and hydrostatic pressure, MERSINO employed a staggered deep well dewatering system, targeting both upper and lower permeable strata.
Methodology/Challenges
Due to the uneven and muddy site conditions, along with the presence of hydrostatic pressure, we used our B180 Casagrande drill rig. MERSINO was able to move around the site with little difficulty because the drill rig was mounted on tracks. With the hydrostatic pressure present, MERSINO had to utilize a heavy drilling fluid to successfully install the deep well system. The ground conditions and proximity to the river required detailed planning and design, which included the installation of wells targeting two different aquifers.
The system was installed in phases over most of 2014 and part of 2015. MERSINO was also selected to perform the operation and maintenance of the system, and has been doing so since pumping was initiated in early 2014.
