A floating barrier float section, and a waterfront barrier system formed from a number of connected float sections. An elongated main flotation tube has radially outwardly extending fence posts with connecting members, such as nets, between them, forming multiple longitudinal net sections about the circumference of the flotation tube, at least one of the net sections extending upwardly and forming a barrier to vessel passage. A vessel strike tends to rotate the flotation tube about its longitudinal axis, absorbing the energy from the strike and rotating the flotation tube to bring another net section into position. An underwater ballast member and a stabilizer float member may be added for additional resistance to rotation.

A rapid-deployment system for containing oil spills and similar water contaminations comprises a pre-manufactured sleeve having air-inflatable or gas-inflatable compartments and water inflatable compartments. In some embodiments uninflated sleeve is stored as a reel of sleeve material, and the deployment system, optionally mounted in a small boat, comprises a machine for inflating the air and water compartments at the site of a spill. In some embodiments, air and/or water compartments may be self-inflating.

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 submergible marine barrier protecting marine installations in a protected zone against intrusion and providing a containment barrier against spread of floating spills or bodies. The body of the barrier is supported above water by a main body thus preventing intrusion and containing floating spillage. A weight in main body keeps the barrier upright, and a rigid floatation chamber in the main body keeps it afloat when full of air. A skimming pipe collects floating pollution. Flooding the floatation chambers causes the barrier to submerge allowing access to the protected zone and protecting the barrier from storms. Body, main body, and floatation chambers are made of extruded material with flotation properties (e.g. plastic pipes). Floatation chambers are connected by air hoses and have air venting tubes at their bottom. Sensors detect approaching intruders and pollution, while spikes, barbed-wire and diver-net or any known barrier are used to stop them.

A method and system for collecting objects floating on or suspended near a surface of water. A collecting system is employed comprising a floating barrier. The collecting system is unanchored to or on the seabed such that the collecting system is free to move along the surface of the water. A submerged portion and non-submerged portion is provided connected to the floating barrier, such that a velocity of the floating barrier along the surface of the water differs from a surface velocity of the water at the location of the floating barrier. Collected plastic objects can be recycled. Further, the ocean currents are followed while being able to collect plastic.

Some embodiments relate to a boom for containing floating material spilled in water comprising: an elongate sheet comprising a plurality of spaced apart units, each unit configured to self-expand from a folded state upon deployment; each unit comprising: a plurality of plates forming an upper portion and a lower portion, the upper portion and the lower portion defined along a vertical axis of the boom unit; and a plurality of stiffening elongate rods, each of the plurality of elongate rods interconnecting at least two plates.

A floating garbage cleaning device for floating garbage on water comprises a plurality of single-section flexible floating bodies which are sequentially connected to form an ultra-long flexible floating body main body; every two adjacent single-section flexible floating bodies are connected through a butt joint device; two ends of longitudinal flexible rods; flexible transverse nets and flexible longitudinal nets are arranged between the longitudinal flexible rods in a spaced and covering manner; stabilizing buoys are fixed with the ultra-long flexible floating body main body; intercepting net aprons are arranged at the bottom of the ultra-long flexible floating body main body; counterweights are arranged at the bottoms of the interception net aprons; garbage collection nets are arranged between two adjacent single-section flexible floating bodies; and the ultra-long flexible floating body main body is provided with a mooring system.

An oil spill clean-up and recovery system for marine vessels, which includes a pivoting and height adjustable boom extending from the vessels, which has upper and lower frameworks that are generally parallel. This includes an oil containment panel which is vertically oriented, movable, and generally laterally secured between the frameworks. A plurality of floats are secured to the oil containment panel and maintain it about the surface of a body of water for containing oil or other undesirable liquids or debris. A plurality of floating oil evacuation tubes are height adjustable and attached to separate floats, each tube having an inlet for receiving oil around the water line. The floating oil evacuation tubes are laterally positioned in proximity of one-another, and in front of the oil containment panel. The oil containment panel collects, contains, and deflects oil to the floating evacuation tubes, which then receive and delivery oil to the tanker.

A floating garbage cleaning device for floating garbage on water comprises a plurality of single-section flexible floating bodies which are sequentially connected to form an ultra-long flexible floating body main body; every two adjacent single-section flexible floating bodies are connected through a butt joint device; two ends of longitudinal flexible rods; flexible transverse nets and flexible longitudinal nets are arranged between the longitudinal flexible rods in a spaced and covering manner; stabilizing buoys are fixed with the ultra-long flexible floating body main body; intercepting net aprons are arranged at the bottom of the ultra-long flexible floating body main body; counterweights are arranged at the bottoms of the interception net aprons; garbage collection nets are arranged between two adjacent single-section flexible floating bodies; and the ultra-long flexible floating body main body is provided with a mooring system.

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.
