<p>To reduce leakage in the event of a hull nupture of a tank vessel having a liquid cargo with a specific gravity less than water, the tank vessel has a watertight compartment between having a watertight horizontal bulkhead in it, above the lock waterline of the tank vessel and at a distance above the hull bottom which is less than or equal to H(Sw/Sc. H represents the vertical height of the waterline of the vessel above the bottom; Sw represents the specific gravity of water and Sc represents the specific gravity of the liquid. The horizontal bulkhead forms separate upper and lower watertight liquid receiving tanks above and below the waterline. The upper one of the tanks has a vertical height which is less than that of the lower one of the tanks. The liquid cargo tanker construction reduces cargo losses at sea and in part from bottom or side hull damage, corrosion, fracture leakage and tanker operational or personnel error.</p> |
