The towing submarine barrel can carry huge cargos at a very low cost and even lower insurance cost, without any waste time for the towboat (6), since the loading and unloading takes place a the mole (5), while the towboat (6) is disconnected and connects to antother submarine barrel and carries it. This is because the loading and unloading had to be done with the towboat (6) disconnected from the towing submarine barrel, because it goes up and down the sea surface, while their connections (11) and the carrying must be done in a fully loaded towing submarine barrel in order to avoid shifting of the cargo. |
