Abstract
A protective composite liner for installation inside a vessel, such as a supertanker, is proposed with an outer layer of high strength fibers, a middle layer of flexible, high strength, resilient film material, and an inner chemical resistant layer. Means for anchoring the protective composite liner and sensor means for detecting a leak are further provided for use with the liner of the present invention.
Claims26
A protective composite liner for containing a liquid or material in a vessel, said protective composite liner comprising a flexible structure including:
- an outer layer having one or more layers of high strength fibers;
- a middle layer normally attached to at least a portion of the inner surface of said outer layer, said middle layer having one or more layers of flexible, high strength, resilient film material;
- and
- an inner layer normally attached to at least a portion of the inner surface of said middle layer such that said inner layer is maintained in substantially opposing relationship with said middle layer, said inner layer having one or more layers of chemically resistant or chemically inert material, and adapted for contact with a liquid or material to be placed in contact therewith.
A containment means for containing liquids or materials comprising:
- a vessel having an inner surface enclosing a space;
- a protective composite liner disposed along at least a portion of said inner surface, said protective composite liner comprising a flexible structure including:
- an outer layer having one or more layers of high strength fibers;
- a middle layer normally attached to at least a portion of the inner surface of said outer layer, said middle layer having one or more layers of flexible, high strength, resilient film material;
- and
- an inner layer normally attached to at least a portion of the inner surface of said middle layer such that said inner layer is maintained in substantially opposing relationship with said middle layer, said inner layer having one or more layers of chemically resistant or chemically inert material, and adapted for contact with a liquid or material to be placed in contact therewith;
- and
- means for anchoring said protective composite liner to at least a portion of said inner surface of said vessel.
A protective composite liner for containing a liquid or material in a vessel, said protective composite liner comprising a flexible structure including:
- an outer layer having one or more layers of high strength fibers;
- a middle layer attached to at least a portion of the inner surface of said outer layer, and adapted to separate from said outer surface as a safeguard upon impact of an object on the outer surface of said outer layer, said middle layer having one or more layers of flexible, high strength, resilient film material;
- and
- an inner layer attached to at least a portion of the inner surface of said middle layer, said inner layer having one or more layers of chemically resistant or chemically inert material, and adapted for contact with a liquid or material to be placed in contact therewith;
- and
- means for anchoring the protective composite liner to at least a portion of the inner surface of a vessel, wherein said means for anchoring is frangible to allow the protective composite liner to separate from attachment to the inner surface of a vessel at a pre-determined stress level as a safeguard upon impact of an object on the outer layer of the protective composite liner.
