Conclusion This innovative geotextile bag container/geogrid lifting and placement technology combined with the installation methodology enabled the ACP's Engineering and Maintenance Division to respond rapidly to a serious threat to the 100-plus-year-old Panama Canal locks that, if not addressed in a timely fashion, could have caused catastrophic damage resulting in both revenue losses and construction costs in the millions to the Panama Canal. In addition, the innovative solution allowed for the required repairs and erosion protection to take place during scheduled maintenance windows without any loss of income for Panama Canal operations. Following the success of this geosynthetic technology in the Panama Canal, the technology was applied to solve severe erosion problems at a major offshore oil terminal located 12 miles (20 km) off the northern coast of Colombia in 100 feet (30.5 m) of water.

Also, Zehong Yuen should be recognized for developing the analysis programs to calculate the factors of safety for the geotextile bag containers and the pullout resistance of the Geogrid Friction Lifting Harness. This project is dedicated to our colleague, Bruce Lacina, who passed away this past year after a long battle with cancer. Without his technical review and support on our ideas, this project would never have gotten off the ground.
