Research on adaptive ship type for new channel of Three Gorges Project

Abstract

Under the background that ships waiting for locks is becoming normal and increasingly intensified, the need to build a new channel of Three Gorges to enhance the navigability of the golden waterway of the Yangtze River is very urgent. The construction of new channel ship locks will inevitably involve the coordination of the new channel representative ship types and existing ships and ship locks and joint scheduling. This article studies the rules of necessary freight rate (RFR), energy efficiency design index (EEDI), transportation efficiency with the length and the width of the ship based on the limitation of channel and lock on the main dimensions of ships. The main dimension series of representative ship types suitable for the new passage of the Three Gorges Project are put forward.
