Afin d'atteindre cet objectif, une entrée de réception et de distribution d'eau sur le flanc du navire, pour recevoir l'eau douce provenant d'ailleurs que la zone aquatique, communique par tuyaux et vannes avec les orifices d'admission d'eau des pompes (9L, 9R) de transport d'eau de lestage disposées dans le navire pour recevoir, transporter et vidanger comme eau de lestage de l'eau de mer ou de l'eau douce provenant de la zone aquatique où flotte le navire. En plus, l'entrée de réception et de distribution d'eau communique, par tuyaux et vannes, avec les orifices de refoulement des pompes (9L, 9R) de transport d'eau de lestage.
