Abstract
Abstract A protective covering for a submerged structure such as a boat, drydock, barge, float, pier, bulk head, and the like. The covering includes a pliable generally waterproof sheet and attachment means for securing spaced portions of the sheet to the surface of the structure to be protected whereby the sheet will resist deterioration of the structure. A novel method of installing the protective covering utilizing a plurality of buoyancy units is disclosed. The use of such buoyancy units permits the covering to be readily maneuvered underneath a floating structure so that the structure may be easily covered in situ.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
88 words
Protective covering apparatus for a submerged structure, comprising: a pliable, generally waterproof sheet; a plurality of battens; attachment means for securing said battens to spaced portions of said structure to define a plurality of independent modules; and seal means interposed between said battens, said sheet and said structure whereby circulation of water in the space defined by said modules and the ambient water outside said modules is restricted to thereby maintain the water in said space stagnant to marine borer attack on the submerged portion of said structure.
Claim 2
Dependent Claim
88 words
Protective covering apparatus for a submerged structure, comprising: a pliable, generally waterproof sheet; a plurality of battens; attachment means for securing said battens to spaced portions of said structure to define a plurality of independent modules; and seal means interposed between said battens, said sheet and said structure whereby circulation of water in the space defined by said modules and the ambient water outside said modules is restricted to thereby maintain the water in said space stagnant to marine borer attack on the submerged portion of said structure.
Claim 3
Dependent Claim
88 words
Protective covering apparatus for a submerged structure, comprising: a pliable, generally waterproof sheet; a plurality of battens; attachment means for securing said battens to spaced portions of said structure to define a plurality of independent modules; and seal means interposed between said battens, said sheet and said structure whereby circulation of water in the space defined by said modules and the ambient water outside said modules is restricted to thereby maintain the water in said space stagnant to marine borer attack on the submerged portion of said structure.
Claim 4
Dependent Claim
88 words
Protective covering apparatus for a submerged structure, comprising: a pliable, generally waterproof sheet; a plurality of battens; attachment means for securing said battens to spaced portions of said structure to define a plurality of independent modules; and seal means interposed between said battens, said sheet and said structure whereby circulation of water in the space defined by said modules and the ambient water outside said modules is restricted to thereby maintain the water in said space stagnant to marine borer attack on the submerged portion of said structure.
Claim 5
Dependent Claim
16 words
Appartus as set forth in claim 1 wherein said seal means include synthetic plastic foam strips.
Claim 6
Dependent Claim
17 words
Apparatus as set forth in claim 1 wherein said battens are covered with a watertight sheet material.
Claim 7
Dependent Claim
51 words
Apparatus as set forth in claim 1 wherein said attachment means further include a plurality of generally rigid panels that are covered on their exterior surfaces with complementary sections of the material from which said sheet is formed and said seal means are disposed at the outer edges of said panels.
