Description: Technical Report
Abstract: This report provides an introduction to the positioning construction techniques used in marine construction. This information is intended to provide guidance for developing and evaluating the positioning systems used for in-the-wet construction of navigation structures. The focus of the report is on assessing various methods for positioning large prefabricated segments, including the stationkeeping and guide systems. The report is divided into two major portions. The first part provides an overview of positioning operations and general engineering requirements for the design and specification of positioning systems. The second part provides descriptions and evaluation of the most common stationkeeping and guide systems that are used to position prefabricated modules in marine construction. The evaluation of each method includes essential equipment, operation requirements, general applicability, and constraints for lift-in and float-in construction in the inland waterways.
