Definitions

  • the object of the new installation means is to support the vessels against all static and inertial forces which they are likely to encounter during use, to protect them and the ship structure from damage in the unlikely but not impossible event of leakage of the cold compressed cargo, and to accommodate all changes in dimensions occurring in the 'vessels and the ship structure as a result of temperature variations.
  • the installation means is to surround the vessels with thermal insulation and is to avoid all Aattachments to the vessels at lwhich stresses might concentrate. All of these ends are to be achieved by means which are simple and economical both in assembly and material costs and which possess a stable operating life over protracted periods of time.
  • the shipboard installation means for elongated pressure vessels disposed vertically in a hold between upper and lower deck structures comprises a pad on the .lower deck structure under each vessel.
  • a shear plug is located on the lower deck structure and extends through and up from each pad.
  • a secondary barrier covers the ⁇ lower deck structure over the pads and closely caps the :upper end portion of each shear plug.
  • Disposed on the secondary barrier closely about the capped portion of each shear plug is a support bowl formed with a concave seat receiving the lower end of the associated vessel.
  • a jacket extends upwardly from each bowl around the lower end portion of the associated vessel.
  • a collar extends through the upper deck structure over each vessel. Attached to the upper end of each vessel is an extension member extend-ing into the associated collar and restrained against all but vertical limited movement with respect thereto.
  • FIG. 1 is a fragmentary elevation showing one vessel mounted in the hold of the ship;
  • FIG. 2 is a fragmentary plan showing several vessels nested together in the hold
  • FIG..3 is an enlarged fragmentary section partly broken away taken along the line 3 3 of FIG. 1;
  • FIG. 4 is an enlarged fragmentary section showing details of the structure of FIG. 3;
  • FIG. 5 is an enlarged fragmentary sect-ion taken along the line 5-5 of FIG. 1;
  • FIG. 6 is an enlarged fragmentary section taken along the line 6 6 of FIG. 5.
  • FIGS. l and 2 part of the hold of a ship is shown defined by lower and upper deck structures 10 and 11 respectively.
  • Each vessel may have a length-to-diameter ratio of 15:1 or more, the greater part of which length is defined by a cylindrical wall 13 closed off by rounded ends 15 and 16 (for the latter, see FIG. 3).
  • a cargo of moderately refrigerated and compressed natural gas is loaded in and removed from each vessel 12 by appropriate access conduit means which eX- tends upwardly from the upper end of each 'vessel
  • Underlying installation means for each vessel 12 includes a flat annular balsa pad 18 resting directly on the lower deck structure 10 axially beneath its associated vessel.
  • a cylindrical wooden shear plug 19 extends through each pad 18 and is located with respect to the lower deck struct-ure by a circular seat dened -by angle clips 20, which permits only rotatable and upward vertical movement of the plug 19.
  • the seat defined by the angle clips 20 is slightly eccentric relative to the axis of the shear plug 19 so that by rotating the shear plug there may be some lateral displacement of its axis. In this way the various supporting elements positioned by the wooden shear' plug as described below may be shifted laterally to accommodate any misalignment of the center line of the associated Vessel.
  • a secondary barrier extends throughout the bottom of the hold and may be continued up a substantial distance against the bulkheads around the lower deck structure of the hold.
  • This secondary barrier includes a foamed insulating layer 23 of polyurethane covering the lower deck structure 10 between the various pads 18.
  • a continuous film 27 of polytetrafluorethylene extends between the plies of this wall throughout the entire area of the secondary barrier.
  • a preformed cap 28 of polytetrauorethylene film is fitted over each upper portion 19a and is heat sealed at 29 to the adjacent film 27 so that there is no interruption in the continuous inert plastic layer.
  • Packing 30 of polytetraiiuorethylene may be deposited along the edge of the upper plywood sheet 25 as shown in FIG. 4 to complete this capped barrier over the upper portion 19a of each respective shear plug 19.
  • each shear plug 19 Disposed on the secondary barrier closely about the capped portions 19a of each shear plug 19 is an annular wooden support -bowl 32 immediately beneath and coaxial with the associated vessel 12.
  • Each bowl 32 is formed with a concave seat 34 receiving the rounded lower end 16 of the associated 'vessel 12 in mating balland-socket engagement which permits the vessel 12 to be displaced angularly to a certain degree with respect to the bowl.
  • the bottom of the concave seat 34 is at an elevation above the upper plywood sheet 25 such that there is clearance between the upper portion 19a 'of the associated shear plug 19 and the lowermost portion of the rounded end 16 of the vessel.
  • the outside diameter of each bowl 32 is slightly greater than that of the cylindrical wall 13 of the vessel 12 so that a peripheral flange portion 35 of the bowl can extend upwardly about the vessel.
  • each bowl 32 Attached to the flange portion 35 of each bowl 32 by fasteners 36 is the lower edge of a cylindrical jacket 37 of aluminum sheet which extends upwardly, say about six feet or so, about the lower end of the vessel 12.
  • a stainless steel shrink ring 39 is secured about this lower edge of the jacket 37 to hold it tightly against the ilange portion 35 of the bowl in sealed relation thereto.
  • a plurality of spacer rings or blocks 41 may be attached to the inside of the jacket 37 at various levels to space it from the wall 13 of the vessel 12 while the upper end of the jacket is held on a wooden ring 42 .against the wall 13 of the vessel 12 by a circumferential strap 43.
  • each vessel 12 is subject to changes in length due to the extreme temperatuure differentials which arise during loading and unloading, the jacket rnust accommodate vertical expansion and contraction and th-is is done by forming it with circumferential corrugations 45 in a horizontal plane.
  • the overlying support means for each vessel 12 is shown in detail in FIGS. and 6.
  • the acccess conduit means comprises a pair of conduits 50 and 51 which extend through respective flared ttings 52 and 53 into the upper rounded end of the vessel 12.
  • the access conduit 50 may extend in a suitable ymanner to the very bottom of the vessel 12 while the other access conduit 51 terminates immediately within the upper rounded end 15 of the vessel as shown in FIG. 5.
  • a collar 55 is xed within an aperture formed in the upper deck structure 11 of the ⁇ ship concentrically above each vessel 12.
  • a wooden ring 56 is fitted closely within each collar 55 and is formed with a vertical groove 57 into which a key 58 on the collar 55 extends loosely as shown in FIG. 6.
  • each vessel 12 Welded concentrically to the upper rounded end of each vessel 12 is a cylinder 61 disposed about the access conduits 50 and 51.
  • the cylinder 61 extends closely through the associated wooden ring 56 and is restrained against all but vertical and limited rotatable movement with respect thereto, the ylatter being permitted by another vertical groove 65 in the wooden ring 56 which loosely receives a key 64 secured to the cylinder 61.
  • a cover 66 is disposed over an upper flange 67 on each collar by bolts 68 and the joint between them is sealed by a gasket 69.
  • Each of the access conduits 50 and 51 projects through the cover 66 and is sealed with respect thereto by respective rubber grommets 70 and 71.
