説明
Twin screw ferry with bow thruster can crab actually to leave/approach the bank by suitable operation of 2 propellers, 2 rudders and bow thruster without assistance of tugs. Then, it is known that the effect of propeller rotational direction such as inward/outward on the crabbing performance is considerably large. To grasp the flow mechanism with respect to the effect of the propeller rotational direction on the crabbing, we carried out free-running and captive model tests using a ship model with 7.10m in the length. The bow thruster model, propeller and rudder models are installed to the ship model together with the equipment for measurements of the horizontal motions and the hydrodynamic forces. As a result, we found that outward-FPP/inward-CPP in the usual operation is the best combination and additional lateral force acting on the hull induced by slip stream flow from a propeller with reverse direction exerts considerable influence on the crabbing performance. The model test results were confirmed by the calculation using a 2D hydrodynamic model.
