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 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.

Garbage collection apparatus for the collection of plastic from a surface of a waterbody with a waterflow. The garbage collection apparatus comprises a base and a horizontal beam mounted pivotably around a vertical axis on the base. Said horizontal beam is mounted displaceably in vertical direction on the base, where said horizontal beam on an underside comprises a collection device for collecting plastic floating on the surface of the waterbody. The collection device extends vertically away from the horizontal beam and extends horizontally in a direction opposite the direction of the water flow in the waterbody, which collection device comprises one of either bars or mesh, where said garbage collection apparatus comprises a first actuator for displacing the horizontal beam in or into vertical direction and where said collection device is connected rotatably to the horizontal beam and where the rotation axis of the collection device relative to the beam is parallel to a main axis of the horizontal beam and where the garbage collection apparatus comprises a controller. Method for removing plastic from the surface of a waterbody with a water flow, with a garbage collection apparatus.

A floating marine barrier is provided whose main components all have substantially equal elastic characteristics, enabling the barrier to better absorb and arrest an impacting vessel. Embodiments include a floating marine barrier including barrier modules each having a flotation device, a supporting framework attached to the flotation device, and impact net support posts attached to the supporting framework. An impact net is attached to each of the support posts and extends between the barrier modules along a longitudinal axis of the barrier; and a main tension strength element is attached to each of the barrier modules and extends between the barrier modules along the longitudinal axis of the barrier to space the barrier modules from each other. The impact net has a first elasticity, and the first main tension strength element has a second elasticity which is substantially equal to the first elasticity.

Means for easily mounting fabric on stakes or posts and installing a fence that separates oil from water on land, on shorelines, or bodies of water are provided, as are methods of fabricating and methods of deploying such a mounting fabric. A fabric can be securely and easily mounted to stakes or posts to fabricate a fence that separates oil from water. The fabric can be a strong, lightweight fabric for separating spilled oil from water.

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 barrier for restriction of passage across or through a body of water, the barrier including a plurality of interconnected buoyant bodies which are spaced apart from one another in a longitudinal array, a plurality of deterrent components on or between the buoyant bodies and obstructive material which in use extends downwardly from the buoyant bodies.

An apparatus for collecting spilled liquid hydrocarbons includes a support beam coupled to an oil rig, the support beam positioned below a flare boom, and a spill pan coupled to an end of the support beam, the spill pan positioned below a burner nozzle of the flare boom. A method includes coupling an oil spill collector to an offshore rig below a flare boom, the oil spill collector including a support beam coupled to the offshore rig and a collection device coupled to an end of the support beam, positioning the collection device below a burner nozzle of the flare boom such that the collection device is horizontally aligned with the burner nozzle, and collecting spilled liquid hydrocarbons in the collection device from the flare boom.

A float assembly that can generate its inflowing water current for collecting water surface debris in a water body. Float assembly can be mounted to a fixed structure at the water body and includes a basket supported by a pair of floats buoyant in water. The basket includes a pump housed in a perforated housing, wherein the pump can be operated to suck water through the inlet also carrying the debris into the basket. The debris of a suitable size can be retained in the basket while the water is pumped out through an outlet. The basket can be switched from an operating state i.e., submerged in water to a stowed state outside the water upon the fixed structure.
