Container Off-Loading and Transfer System (COTS). Advanced Development Test of Elevated Causeway System. Volume II. Elevated Causeway Installation and Retrieval.

摘要

A two-phase advanced development test program was conducted to evaluate the installation, operation, and demobilization of an elevated causeway system. This volume details the portion of the program dealing with the pier installation and retrieval. Pier installation and retrieval methods, lift system, pile positioning, driving and pulling techniques, site and elevated causeway surveys and survey methods, and utilization of associated lift system equipment are covered. A human engineering study was made of both the elevated causeway system hardware and the associated operational procedures. The results of the tests verified the practicality of the elevating mechanisms to perform their functions; however, some modifications concerned with improving construction methodology were deemed desirable. The recommended improvements are noted in the report. (Author)
