This kind of circumstance often happens when the ship is in navigation, from ahead turning to reverse starting.If a fully loaded ship is running at full speed five ahead, it is necessary to reverse starting;First of all,

Reverse reverse.After reversing and reversing, the next step is to reverse and start.Under the condition that the main engine cuts off fuel oil, due to the inertia of the ship, the propeller should be driven to rotate in the forward direction, and the torque generated by such rotation, if it is called reverse torque;Then the torque produced by reversing the main engine is called positive torque;Then, in order to realize reverse starting, the main engine can only realize reverse starting when the ship speed is reduced to make the reverse torque generated by the propeller reduce to less than positive torque (that is, when starting, the positive torque generated by compressed air is greater than negative torque).

It should be pointed out that the counter torque generated by the inertia of the ship is related to the loading of the ship.If the ship is fully loaded, the counter torque is much greater.

Therefore, after reversing, if the positive torque generated by compressed air is less than the inverse torque generated by the inertia of the ship, it cannot be started in reverse.
