Abstract
PURPOSE: To reduce the thickness of an inner bottom of a double bottom tanker, by shaping a space between the inner bottom and an outer bottom of the tanker as a sealed space, by injecting gas into the space and by opposing the gas to the weight of oil in a tank.
CONSTITUTION: A sealed space 3 is formed between an inner bottom 1 and an outer bottom 2, and inactive gas is injected into the sealed space 3 from a feed pump 6 in opposition to the weight of oil 5 in a tank 4. The thickness of the inner bottom 1 can be reduced because the inner bottom does not bear the weight of total oil. The quantity of inactive gas injected is controlled by means of a controller 13. The quantity of inactive gas injected is controlled by controlling valves 8, 10 on the basis of input signals from an oil gauge 11 and a pressure detector 12 in the sealed space 3. When normalcy, the quantity of the inactive gas is controlled so as to balance with the weight H of the oil of upper portions than a load draft line A on the assumption that there happen the emergencies that gas pressure in the sealed space 3 becomes to zero when stranding.
