A removable containment boom anchor includes: an anchor support having a flexible body fabricated of at least one resilient material, and a containment boom connector fastened to the anchor support. The flexible body has a base and a tab extending from the base. The flexible body encapsulates a plurality of permanent magnets.

A containment boom is for confining an oil spill within a restricted area on a water surface, wherein the containment boom has an openable link and connection means for connecting the containment boom at each side of the link to separate towing vessels. A system is for confining an oil spill having the containment boom and a storage means for storing the containment boom, wherein the storage means is configured to be situated at the perimeter of an offshore structure above the water surface, and wherein the lower part of the storage means is configured to be able to be opened and release the containment boom into the water upon deployment of the system. An offshore structure includes the system. A method is for confining an oil spill using the 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.

A barrier 10 for use in an oil spill on water, having a substantially rigid planar member 12 made from plastics, a weight 16 attached to a lower end 14 of the barrier 10, use, art upper portion 12a of the barrier 10 extending vertically above the waterline and a lower portion 12b of the barrier 10 extending vertically beneath the waterline.

A multipurpose combined flexible floating breakwater, wherein each water-surface wave absorbing structure comprises a rubber buoy, a bearing rope passing through a central hole of the rubber buoy, active shackles connected at two ends of the bearing rope, and anti-sliding devices arranged at two ends of the rubber buoy to prevent the rubber buoy from sliding on the bearing rope randomly; a connecting structure comprises a cross-shaped pull ring and a connecting anchor chain, the cross-shaped pull ring is used for connecting adjacent water-surface wave absorbing structures in the same row, and the connecting anchor chain with two ends connected with the active shackles is used for connecting adjacent water-surface wave absorbing structures in different rows; and the purpose of mooring is achieved through a mooring system.

A bottom plate for a marine boom includes a main plate extending in a first plane. The main plate has first and second ends with first and second sides extending there between. The first plane is defined by a longitudinal axis extending between the first and second ends and a lateral axis normal to the longitudinal axis and extending between the first and second sides. Top and bottom surfaces are bounded by the first and second ends and the first and second sides and extend parallel to the first plane. At least one lug is attached to the main plate and extends in a second plane generally perpendicular to the first plane. The lug includes a flange defining an aperture aligned generally parallel with the lateral axis, where radial thickness of the flange increases toward the main plate and decreases away from the main plate.

A barrier for protecting a port, waterway, or off-shore structure is provided. The barrier has a front elongated pontoon which extends substantially the length of the barrier. A net assembly, provided either in sections, or as an elongated net, extends vertically upward from the front elongated pontoon and along the length of the front elongated pontoon. The net assembly is affixed to the front elongated pontoon with one or more net support beams. The front elongated pontoon is supported by a rear pontoon support structure, which may be a series of pontoons, each connected to the front elongated pontoon and spaced apart the length of the front elongated pontoon, or an elongated cylindrically shaped rear pontoon which extends substantially the length of the barrier. In some embodiments, a rear net section is attached to the rear pontoon support structure. In another embodiment of the invention, a barrier system for protecting a port, waterway, or off-shore structure is provided. The barrier system comprises two or more contiguous barrier units, one of which is a barrier according to the present invention that form a perimeter to protect the port, waterway, or off-shore structure and can additionally act as a debris barrier. In one embodiment, the barrier system forms a perimeter protecting a port or waterway. In another embodiment, the barrier system protects an off-shore structure.
