On the other hand, when a generally flat strake made of Invar sheet with rolled up longitudinal edges is used with compressible insulation, the magnitude of the thermal contraction movement is more limited, but within the There is a risk of damage to the first watertight partition under compression and shrinkage, because the extrusion and shrinkage of the insulation creates transverse tensile stresses on the watertight partition, and the expansion gussets on the rolled-up edge of the watertight partition may Insufficient to withstand the corresponding stretch

Embodiment Construction
[0029] Figure 1 shows the double hull of a ship in which the container of the invention is built. This double hull wall forms compartments, each compartment being formed by a number of generally flat longitudinal faces 2 welded along their longitudinal edges to generally form a section of cylinder or cone, said longitudinal sides And welded along the transverse partition wall 3 at the longitudinal end of the compartment. The longitudinal faces 2 and transverse partitions 3 of a compartment form the support structure 1 of the container which will be described below. The transverse partition wall 3 is also double-layered. In general, the longitudinal plane 2 is generally conical with a polygonal director curve in the bow part of the above-mentioned ship (not shown) and cylindrical with a polygonal director curve in the rest of the ship ,As shown in Figure 1. Each pair of adjacent longitudinal faces 2 defines a dihedron 4 whose solid intersection angle A substantially coincide...

Abstract
Watertight and thermally insulating tank intended for the transportation of liquefied gases by sea, said tank being built into a bearing structure (1) comprising longitudinally adjacent faces (2) forming a dihedron (4); said tank comprising two successive watertightness barriers, one of them a primary watertightness barrier in contact with the product contained in the tank and the other a secondary watertightness barrier (14,55,30,40) arranged between said primary watertightness barrier and the bearing structure, a primary thermally insulating barrier (12,13,24,27,28,29,37,38,51,54,71) being arranged between these two watertightness barriers and a secondary thermally insulating barrier (15,16,57,58,31,32,41) being arranged between said secondary watertightness barrier and the bearing structure; said primary watertightness barrier comprising substantially flat running metal strakes (62) and, on each side of the longitudinal solid angle of intersection (A) of at least one of said dihedra, a longitudinal row of corner strakes (65) which are corrugated so that they can deform transversely.
Description
technical field [0001] The present invention relates to a watertight thermally insulated container, in particular for the storage of liquefied gases, such as liquefied natural gas with a high methane content, at a temperature of about -160°C, built into the support structure of a ship, in particular with In the hull of ships transporting liquefied gas by sea. Background technique [0002] French patent application No. 99 / 07254 discloses such a watertight and thermally insulated container built in a supporting structure, especially of a ship, having a polyhedral shape, in particular an irregular octahedral shape, the corners of which are generally at 90 or 135 degrees the corner of the container; the container consists of two successive watertight partitions, the first of which is in contact with the product in the container and the second of which is interposed between the first and the supporting structure, the two The watertight interlayer and the two heat insulation barr...
