Provided is a method and a system for removal of oil under ice through an opening made into ice. The system includes oil booms extending under ice in two different directions from the opening so as to constitute an angle of less than 180 degrees between each other; an oil collection device placed in the opening; and a propulsion device placed on the level of the lower surface of ice at a distance from the opening in the area of the angle so as to provide a flow directed towards the opening between the oil booms in the area of the angle.

A method of containing a spill in an aqueous environment, comprises the steps of: placing a polymeric pipe under the surface level of the aqueous environment in the vicinity of a site of potential spillage; and raising the pipe from under the surface level to a containment level; wherein the pipe forms, when raised, at least a partial boundary around the spill for containing the spill.

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.

An on-board spool-able re-useable containment boom for a waterborne vessel that lies substantially flat and capable of being spooled when deflated and floats in the proper orientation when inflated, that has spool-able re-inflatable float sections which are sequentially inflated during deployment and sequentially deflated during recovery, that can be repeatedly deployed and recovered for the purposes of training and testing, and that can be deployed immediately upon occurrence of an oil spill from a waterborne vessel because of its on-board location and its rapid deployment, and a control system for proper inflation and deflation of spool-able re-useable containment boom during deployment and recovery.

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.
