The maneuvering characteristics of a large container ship with twin propellers and twin rudders were investigated using the
horizontal planar motion mechanism (HPMM) test and computer simulation. A mathematical model for maneuvering motion with four
degrees of freedom (DOF) for twin-propeller and twin-rudder systems was developed and included the effects of roll motion.
To obtain the roll-coupling hydrodynamic coefficients of a container ship, a four-DOF HPMM system having a roll motion mechanism
and a roll moment measurement system was used. At the full load condition, HPMM tests were carried out for two different 12 000-TEU
container ship models, one with twin propellers and the other with a single propeller. Using the hydrodynamic coefficients
obtained from the tests, computer simulations were carried out. Simulation results for the container ship with twin propellers
and twin rudders were compared with the results for the container ship with a single propeller and single rudder. 相似文献

In order to achieve safe navigation, it is important to be able to understand and calculate the effects of an external force on the maneuvering behavior of a ship. This paper analyzes the course stability and yaw motion of a ship traveling under steady wind conditions. A course stability criterion and approximate formulae for the yaw motion in steady wind, including the aero/hydrodynamic force derivatives for the ship, are derived. To confirm the reliability of the criterion and formulae, they were used to investigate a pure car carrier in steady wind. The results of this investigation revealed that course instability appears in the head and following wind directions, mainly under the influence of aerodynamic derivatives with respect to the yaw restoring forces. However, this course instability can be reduced by applying steering control. For winds ranging from head winds to beam winds, yaw oscillation appears when the period is relatively long and the damping is small. The analytical formulae derived here can be used to gain a better understanding of ship maneuvering behavior in steady wind. 相似文献
