Definitions

  • the present invention relates to a liquefied gas carrier, and more particularly to a liquefied gas carrier having an improved hull structure.
  • spherical cargo tanks 2 are fixed on a foundation deck 3 of a carrier by means of cylindrical skirts 4, and hemi-spherical tank covers 7 for shielding the portions of the above-mentioned spherical cargo tanks protruding above an upper deck 5 from the open air are disposed as projecting above the aforementioned upper deck 5.
  • Numeral 12 denotes a pipe tower in which oil pipes,etc. are installed.
  • reference numeral 6 designates a side double hull
  • numeral 8 designates a side plating
  • numeral 10 designates an upper construction.
  • a liquefied gas carrier which comprises a plurality of cargo tanks arrayed in the length-wise direction of a hull, cylindrical skirts for holding the cargo tanks within a hold, and an upper deck covering the upper side of these cargo tanks and being continuous in the lengthwise direction of the hull, each of the cargo tanks being formed in a flat spherical shape with its diameter in the vertical direction shortened with respect to its diameter in the equatorial plane.
  • the upper deck is formed of a sheet member that is continuous in the lengthwise direction of the hull, the upper deck can act as a longitudinal strength member of the hull.
  • the height of the upper structure of ships can be reduced.
  • cargo tanks 11 disposed on a foundation deck 3 of a liquefied gas carrier 1 are formed in a flat spherical shape with its diameter in the vertical direction shortened with respect to its diameter in the equatorial plane, and four such cargo tanks 11 are fixedly arrayed in the lengthwise direction of the hull on the foundation deck 3 of the liquefied gas carrier 1 by means of cylindrical skirts 4.
  • a flat upper deck 5 that is continuous in the lengthwise direction of the hull and covers the upper side of these cargo tanks.
  • Numeral 9 denotes a flying passage.
  • the both side edge portions 5a of the upper deck 5 are formed in a downwardly tilted shape so as to follow the profiles of the flat spherical cargo tanks 11 as shown in Fig. 3. Accordingly, in the case of the second preferred embodiment, a wind resistance against lateral wind can be reduced as compared to the first preferred embodiment shown in Fig. 2.
  • numeral 12 denotes a pipe tower in which oil pipes, etc. are installed.
  • the upper deck covering the upper side of the cargo tanks is formed so as to be continuous in the lengthwise direction of the hull and in a flat shape owing to the above-described construction, the effect of the upper deck as a longitudinal strength member of the hull can be enhanced, and for instance, in a liquefied gas carrier consisting of four tanks having a loading capacity of 125,000 m3, a hull weight can be reduced by about 1000 tons as compared to the liquefied gas carriers in the prior art.
  • FIGs. 2 and 3 are illustrations of cargo tanks having the same capacity on the same scale, and in the case of liquefied gas carriers consisting of four tanks having a loading capacity of 125,000 m3, in contrast to the fact that the spherical cargo tank in the prior art had a diameter of about 40 m, the height of the upper deck according to the present invention can be lowered by about 6 m as compared to the height of the tank cover in the prior art.
  • the cargo tank is supported only by the skirts 4 as the prior MOSS type spherical tank. Accordingly, there is space between the bottom of the tank 11 and the foundation deck 3 or the inner bottom plate of the two-fold bottom.
  • the tank is not supported by heat insulating material.
  • the strength of the bottom of the spherical tank supported by the skirts is obtained by its curvature against the inner pressure and the pressure of the liquid. This is also true in the case of a non-spherical tank of this invention.
  • the required thickness t of the spherical cell subjected to the inner pressure is:
  • the tank is comprised of the cylindrical equatorial portion, the top portion with panel structure and the bottom composed of an elliptical body whose longer axis length is equal to the radius of the equatorial portion or the bottom composed of semi-elliptical body which is the combination of circular arcs.
  • the liquefied gas carrier according to the present invention provides the following effects and advantages:
