An oil containment barrier module as defined in claim 16 further comprising coupling means connected at each opposite end of said belt and adapted to engage other barrier modules to form a barrier system. .[.18. A barrier system for containing an oil spill in a body of water comprising: a plurality of barrier modules coupled together end to end in a predetermined string formation, and at least one mooring line connected to said string of barrier modules for maintaining the relative position of said barrier system within said body of water; each of said barrier modules comprising a composite structure having a buoyant, substantially water impervious upper section and a water absorbent lower section, said lower section representing concurrently the principle ballast for said upper section and the subsurface barrier for the module..]. .[.19. A barrier system as defined in claim 18 wherein said upper and lower sections of each module are formed from at least one material selected from the class consisting

Claim 10

of flexible foam, porous rubber, and sponge having of low density..]. 20. A barrier system .[.as defined in claim 19.]. .Iadd.comprising: a plurality of barrier modules coupled together end to end in a predetermined string formation, and at least one mooring line connected to said string of barrier modules for maintaining the relative position of said barrier system within said body of water; each of said barrier modules comprising a composite structure having a buoyant, substantially water impervious upper section and a water absorbent lower section, said lower section representing concurrently the principal ballast for said upper section and the subsurface barrier for the module, wherein said upper and lower sections of each module are formed from at least one material selected from the class consisting of flexible foam, porous rubber, and sponge having of low density, .Iaddend.wherein the lower section of each barrier module is composed of two segments and a relatively thin belt-like member located in a vertical plane between said segments and extending for substantially the entire length of the module.

Claim 11

A barrier system as defined in claim 20 further comprising coupling means connected to said belt-like member at each opposite end face of said

Claim 12

barrier module. 22. A system as defined in claim 21 wherein the end faces of each barrier module have a recessed surface and wherein said coupling means are connected to said belt-like member within said recessed surface such that upon interconnecting the coupling elements the barrier modules

Claim 13

butt against each other to provide a relatively liquid-tight seal. 23. A system as defined in claim 22 wherein said mooring line is connected to the belt-like member in one of the barrier modules of the system at a location intermediate the end faces of the module. .Iadd. 24. An elongated floating barrier module for use in a system to contain oil spilled on water, said barrier including a buoyant portion filled with a flexible foam and impervious to water, an underwater barrier element supported by said buoyant portion and extending the length of the barrier and downwards from the buoyant portion into the water, and a water absorbing portion made of foam attached to said barrier element which when soaked with water is non-buoyant and provides the principal ballast for said barrier. .Iaddend..Iadd. 25. A barrier as in claim 24, said water absorbing portion being formed of reticulated foam. .Iaddend..Iadd. 26. A barrier as claimed in claim 25, said underwater barrier element including a sealing coating adhering to said water absorbing portion. .Iaddend..Iadd. 27. A barrier as in claim 24 including a stress carrying member running from end to end of said barrier, said stress carrying member having mooring ties attached thereto and being bonded to said water absorbing portion said mooring ties being at the center of pressure of the barrier cross-section. .Iaddend..Iadd. 28.
