[Also in Division F4] A ship's hull 30, Fig. 3 (not shown), having insulation 31, has a main tank 33 therein for containing liquid surrounded by a second tank 36, each tank being formed from a non-metallic membrane of a flexible and elastic material, e.g. nitrile rubber or polyester urethane. The space 37 between the tanks is filled with a pressurized gas, a flexible cellular material or a liquid. Alternatively, the upper part of the space may be filled with cellular material and the separated lower part by a pressurized gas. The space 37 may also be divided into several sealed chambers by membranes which extend between the tanks, each chamber being filled with gas at different pressures. Inflatable reinforcing ribs (Fig. 2, not shown) filled with an inert gas may be arranged on the internal surface of the main and/or the second tank. |
