The world’s first floating concrete container terminal was put in service in 1982. After being towed 1600 miles from the manufacturing site in Tacoma, WA, the two 350’ long pontoons were post-tensioned together in Valdez into a single 100' wide x 700' long floating dock. Eight concrete gravity anchors hold it in place, and two 200' long steel box girder bridges connect the dock to shore. Each of the two pontoons is composed of 16 watertight compartments, with longitudinal and transverse post-tensioning ensuring the watertight integrity of the hulls.
