| Abstract: |
A container tank useful in the transportation of liquified gases at cryogenic temperatures in a tanker vessel comprises a primary liquid-tight barrier and a secondary liquid-tight barrier spaced apart from and surrounding the primary barrier and including a lower drip pan portion which is structurally integrated with the primary barrier and an upper splash shield portion which is structurally independent of but may be mechanically fastened to the primary barrier, i.e., the splash shield may be supported by the primary barrier but not structurally integral with said primary barrier.

First Claim:
Show all 10 claims |
What is claimed is:
1. A container for liquefied gases at cryogenic temperatures for use in a tanker which comprises, in combination: a primary tank of sufficient structural strength to contain the liquefied gas, said primary tank containing internal structural means fixed to the interior walls thereof; a larger liquid-tight secondary enclosure substantially similar in shape to said primary tank and completely surrounding said primary tank, said secondary enclosure containing a lower portion of predetermined thickness less than the thickness of the primary tank but sufficient to retain small quantities of the liquefied gases that may leak through said primary tank; thermally conductive structural means for maintaining said lower portion in spaced relationship and structurally integral with said primary tank, said structural means having sufficient depth to prevent failures in the primary tank from propagating to said lower portion; said secondary enclosure also containing a liquid-tight upper portion for deflecting seepage through upper portions of the primary tank into said lower portion; means for mechanically fastening said upper portion of said secondary enclosure to said lower portion and said primary tank solely for support and to permit relatively quick assembly and disassembly while maintaining said upper portion structurally independent of said primary tank and said lower portion; said lower portion being spaced at a first distance from the sides of said primary tank, and said upper portion being spaced at a second distance which is less than said first distance from said primary tank.
