<p>Improvements in partial secondary barriers for selfsupporting, axi-symmetrical cargo tanks on board marine vessels the improvements consisting of a tank, preferably cylindrical in shape, installed one under each cargo tank, the section of the tank being substantially less than the maximum horizontal section of the cargo tank, and the tank being structurally joined to the inner shell of the double bottom of the vessel and comprising a stiff external wall, an internal thermal insulation and an inner impermeable layer, capable of withstanding the low temperatures of the liquid being collected. The discharging into the interior of the tank are pipes originating from the internal surface of the thermal insulation of the cargo tank and which serve to drain off any leaks that may occur in the cargo tank, the tank being also equipped with a device for discharging the collected leaking liquid.</p> |
