Disclosed is a hydrophilic material oil fence having a double-porous mesh. The hydrophilic material oil fence having the double-porous mesh includes a floating body floating on a water surface, and a skirt coupled to an upper portion and a lower portion of the floating body and made of a hydrophilic material through which a hydrophilic fluid selectively passes. A mesh hole size of a partial region of the skirt and a mesh hole size of the other region of the skirt are different.

A barrier member for an oil spill barrier configured for retaining one or more weights when assembled or combined with a second barrier member to form a barrier unit. A first barrier member has a first side for facing away from the second barrier member and a second side opposite the first side for facing towards the second barrier member in the barrier unit, the second side includes a substantially planar area for abutment to the second barrier member. The second side has at least one recessed region for receiving the one or more weights, the recessed region being recessed from the second side in a direction towards the first side relative to a plane of the substantially planar area. The second side has first and second elongate half-channels disposed to opposing sides of the at least one recessed region.

The present invention generally relates to containment and control of an oil spill caused by a damaged or broken riser in deep water. More specifically, the present invention relates to a reusable unit that will contain oil spills to a specific location and will also allow oil to be harvested as it flows to the top of the unit while minimizing or even eliminating any environmental clean-up impact or cost. The unit of the present invention is dropped over a damaged or broken riser in a closed position, the unit is released and stabilized in sections until the surface is reached and the containment unit is completely erected.

Some embodiments of the invention relate to a spill containment boom unit for deployment in ambient water, using water absorbing material, such as SAP, to encourage expansion of a chamber thereof. Some embodiments provide boom units which comprise one or more surfaces which form at least one hollow chamber, wherein at least one wall of the hollow chamber comprises at least one fillable compartment.

A marine barrier system is provided with two elongate buoyant members, a net support member between and above the two buoyant members, an elongate load bearing member spaced from and between the buoyant members, and a lower ballast member between the two buoyant members and below the buoyant members. Stanchions extend between the members to support them and maintain the spacing between them. An impact net is attached to the net support member and the load bearing member. When a moving vessel impacts the impact net, the net deflects to transfer a force of the impact to the net support member, the stanchions, the load bearing member and the buoyant members, which engage the water to transfer the impact force to the water and arrest the motion of the vessel. The ballast member provides a force to restore the barrier to an upright position when the barrier rotates from vertical.

The invention relates to a water intake floating row cleaning system, including first vertical guide rail assemblies, a floating row, submersible pumps, water spraying assemblies, second vertical guide rail assemblies, floating fences and pumping assemblies, wherein the water spraying assemblies are communicated with the submersible pumps, and the submersible pumps pump the water of the river channel and spray the water towards the outside through the water spraying assemblies; and the floating fences stretch across the water intakes and float along with a water level, and the pumping assemblies are used for pumping out garbage blocked by the floating fences. The invention has the effect of efficiently cleaning the floating garbage at the water intakes.

Systems, apparatus and methods useful for collecting and separating floating debris and water from a body of water on a vessel, the vessel including at least one inflow regulator (IFR) chamber at least partially separated from a main collection compartment and at least one fluid discharge pump.
