ANALYSIS OF FORCES ACTING ON CIRCULATION CONTROLLABLE HULL AND THE INFLUENCE ON SHIP MANOEUVRABILITY

In this paper, the forces acting on a Circulation Controllable Hull (CCH) are analyzed with the forces acting on the hull with rudders on the basis of experiment results of a tug model with CCH. The test results show that at low speed the CCH may produce a larger turning moment than that generated by the hull with rudders, while at high speed the CCH may also produce enough turning moment to meet the requirements of the ship manoeuvrability. As a new method of ship manoeuvring, it may greatly improve ship manoeuvrability, especially at low speed. Since CCH is simple in structure and has no movable parts and it does not change the shape of the hull, the application of CCH to real ships is feasible.
