Yaw damping installation for sea going ships, consists of several identical yaw damping systems of Frahm type, consisting each of two side tanks on backboard and control board

摘要

The installation consists of several tank systems (A,B) of two side tanks (1a,1b;2a,2b) each. They are interconnected at lower side by fluid (13) filled duct (3), and at top side by air duct (4). Each tank system is partly filled with fluid, preferably water.Tanks of each yaw damping installation are of identical performance and interconnected by control and can be operated simultaneously, or separately. Each tank system is enclosed and antimetric filled, i.e. when one side tank is full, the other one is empty, with antimetry maintained by stop valves.
