Abstract

There is not any design principle and reference for channel dimensions for immersed tube element towed by selfpropelled catamaran with dynamic positioning(DP) system in restricted waters in current specifications. As a result, the existing technical data and channel design methods are summarized, and the design concept of compound channel is proposed based on navigation simulation and calculation. And then comprehensive analysis and calculation are carried out based on the technical parameters such as ship type, channel geology, navigational speed, etc., the design principles and methods for compound channel are established by means of simulated navigation, and the key technical parameters are obtained. By adopting compound channel, the safety of immersed tube and ship can be guaranteed, the dredging amount of waterway excavation in restricted waters can be effectively reduced, which help promoting the protection of ecology and marine environment; at the same time, the effective use of resources and economization and environmental protection can be realized.
