The state-of-the-art terminal will have both electric and hybrid equip- ment that will ensure efficient operations while reducing emissions. Phase One will house the tallest ship-to-shore (STS) cranes at the Port of Charleston with five cranes having a 169-foot lift height, as well as 25 new hybrid rubber-tired gantry (RTG) cranes. The Leatherman Terminal will be built in phases during the next de- cade. When completed, the terminal will have three berths capable of handling 2.4 million TEUs of cargo, doubling the port’s existing throughput capacity. It is named for Hugh K. Leatherman, who has served as a South Carolina State Senator since 1980. Additional information can be found at the Plastics Pipe Institute's website: www.plasticpipe.org. About PPI The Plastics Pipe Institute, Inc. (PPI) is the major North American trade association representing all segments of the plastic pipe industry and is dedicated to promoting plastic as the materials of choice for pipe and conduit applications. PPI is the premier technical, engineering and industry knowledge resource publishing data for use in the develop- ment and design of plastic pipe and conduit systems. Additionally, PPI collaborates with industry organizations that set standards for manu- facturing practices and installation methods.

“We found out that polypropylene pipe is forgiving and sturdy. We were actually digging the trenches in the rock and even with that rigid rock, the pipe worked well,” Fulton continued. “The problem with another alternative - corrugated steel - is that with the rock it’s an cor- rosional type thing. If you put in the corrugated metal pipe in there with all the material, it would erode away within 10 years. We found that out around here. We do have a lot of rock but in some areas, we were below sea level, and we had some sandy material and that doesn’t do real well with corrugated metal pipe. Plus, it’s just not as sturdy where you need a double wall installation.”
