[ EN ] The current return results from the flow, and is located toward the stern. This current is opposed to the direction of the ship and increases the friction at the bottom. This friction exerts a drag force on the water in the direction of the boat. To compensate for this friction, the water level in front of the boat becomes higher than the rear level. With this lowering of the water, the boat’s law affects the quay or jetty. The return current has very low erosive action on the seabed.

Impair the performance of the ship at a certain speed, it is not necessary to study this current situation in this report. ln Soalara, for all the depths of the sea, the speed generated by the propeller of all jets (ship 2 tugs) exceeds:0,3 node to a mean radius of 200m and 0.15 node to a mean radius of 300m.
