Description
Captive model tests were carried out to capture the hydrodynamic force characteristics on maneuvering for a twin propeller and twin rudder ferry with L/B=6.25, B/d=3.75 and C_b=0.53. Based on the test results, the hydrodynamic force derivatives and coefficients were determined according to the MMG model procedure including an equivalent single rudder model newly proposed. In the equivalent single rudder model, two rudders for port and starboard are treated as a single rudder arranged in centerline of the hull within restriction of the same rudder angle for port and starboard. The equivalent single rudder model can avoid complexity of the existing rudder force model for the twin rudder ship. The hydrodynamic force coefficients with respect to hull, propeller and rudder for the ferry are provided together with hull hydrodynamic force characteristics due to bow thruster operation. These data is useful for maneuvering simulation of a similar ferry.
