Abstract: The great stream power in shiplock filling and emptying system with high head may cause harm to the safety of shiplock operation and ship berthing. Choosing a proper type of filling and emptying system will be vital in guaranteeing engineering safety. With the construction of Datengxia shiplock which is a large single lift lock with super-high head, the existing filling and emptying systems cannot meet the shiplock requirement, and a system with better energy dissipation effect is in urgent need. According to relative researches on Datengxia shiplock and successful experiences in the layout patterns of shiplock’s filling and emptying system with high head at home and aboard, we summarize the matching relations between shiplock type and operation head as well as chamber scale, and present a new dynamically balanced system pattern fit for the main features of Datengxia shiplock, with autonomic diversion outlets in the whole chamber at 4 zones. This new type of shiplock filling and emptying system with interior energy dissipation function can provide reference for the design and study of subsequent large shiplocks with super-high head.
