Embodiment Construction

[0029] Illustrative embodiments of the invention are described below as they might be employed in the use of the design for an insulation deck suspended from the roof of a LNG vessel or other fluid storage tank. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

[0030] Further aspects and advantages of the various embodiments of the invention will become apparent from consideration of the followi...

Abstract

A non-welded deck used to support insulation from the roof of a low temperature or cryogenic storage tank is disclosed. The deck may be comprised of a plurality of spaced apart bars with metal sheets covering the spaces between the bars. The edge of the metal sheets may be clamped to the bars to form the deck. The edges of adjacent metal sheets may overlap and be clamped together in such a way as to deform the sheets creating a metal-to-metal vapor and dust proof seal. The plurality of clamping bars and support bars may secure the metal sheets with sufficient strength to allow the entire deck to support loadings as a stressed membrane. The tank may be constructed with hardware that remains secure even after being subjected to repeated thermal cycling of over 200° Celsius (360° Fahrenheit).

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates generally to an insulation deck suspended from the roof of a low temperature tank, such as a liquid natural gas tank for example. [0003] 2. Description of the Related Art [0004] Every year more and more natural gas reserves are discovered. Unfortunately, much of it is found far from the major consumer countries making economical transportation and distribution vital. Presently far more natural gas is removed from discovered natural gas reserves than is consumed globally. The excess amount of natural gas requires the rapid construction of storage facilities to hold the extracted natural gas. The size of the needed storage facilities and vessels can be decreased if the natural gas is stored at cryogenic temperatures, which liquifies the natural gas. Liquifying natural gas decreases the volume of the natural gas by more than 600 percent. Thus, liquid natural gas (“LNG”) requires less stora...
