Abstract
Abstract A high freeboard barrier for water carried pollutants includes a series of end to end connectable tubular boom sections with each boom section including an upstanding fin and a depending skirt, and further fabric means extending from at least below the water line to substantially above the fin to thereby increase the freeboard of the barrier. The fabric may be fireproof to reduce oil spill fire damage to the barrier. The fabric means may be of the type which extends the length of the skirt or substantially therebelow and the fabric means may be of the add-on type for use with existing barriers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
109 words
A high freeboard barrier for water carried pollutants comprising a plurality of hollow tubular floatation members each having a depending skirt, cable members extending along each side of the barrier, connector means interconnecting said cables and attaching said cables to the barrier at a plurality of spaced points, a plurality of upstanding spaced apart battens extending along each of said floatation members, means attaching each of said battens to its respective floatation member, and removable auxiliary fabric means supported by said battens and extending from at least below the water line of the barrier to substantially above the tubular floatation member to thereby increase the freeboard of the barrier.
Claim 2
Dependent Claim
109 words
