A new portion of the Freeport, Texas Wharf was meant to allow an additional two container ships to be unloaded each day. However, before it was put into service, the entire 800 foot by 109 foot wharf began sliding into the shipping channel. GeoPrac sponsor Nicholson Construction was tasked with installing 30 multi-strand soil anchors to stabilize the wharf. The anchors were each 140 feet long and encased in Class I corrosion protection because of the aggressive environment. The design loads up to 150 kips were achieved in the soft clay. The wharf is now stabilized and final repairs are being made before it opens to ship traffic. [Source: Nicholson Construction Company. Image: Nicholson Construction]
