A water surface garbage salvaging device, comprising a demihull, a large garbage salvaging device and a small garbage cleaning device; wherein the large garbage salvaging device is arranged on a front portion of the demihull, and the small garbage cleaning device is arranged on a rear portion thereof; the large garbage salvaging device comprises a paddle wheel, slipways and a large garbage storage bin; and the small garbage cleaning device comprises a filter mesh, a guide rail slider mechanism, a lifting mechanism and a pulley system, a hanging bracket is arranged above the filter mesh.

A marine debris collection device includes a first debris collector to remove non-minute debris contained in debris floating on water by allowing the debris to flow thereinto together with the water, and a second debris collector to remove minute debris by adsorbing the minute debris onto a microbubble generated when the water flows into the second debris collector from the first debris collector via a connection pipe.

A module for retrofitting a boat for collection of floating biomass has a telescoping beam that spans the width of the boat and connects to aft-ends of levers that rest on the gunwales. The telescoping beam extends beyond both gunwales such that outboard net holders can be disposed thereon. Nets are attached to and held open by the net holders. The nets are at least partially submerged and fill with sargassum as the boat moves forward. Longitudinal drag forces are resisted by chains that connect the levers to the bow. Torsion around the telescoping beam is resisted by pretensioned straps that pass under the boat and over the aft-ends of the levers, which extend towards the bow to minimize strap tension and reaction force against gunwales. Horizontal moments in the outboard portions of the telescoping beam are absorbed by the inboard portion of the telescoping beam.

Oil-collection system and oil-collecting barge. The system comprises a towing vessel and a transport barge, which has a catamaran structure, so that there are oil collectors in its pontoons. Guide booms are attached to the sides of the barge, with a structure that is tubular frame around a wall, in which the air space or volume of the lowest tube corresponds to the boom's own weight. When using a larger capacity in collection, the additional booms on the deck are filled with air and simultaneously pulled into operating condition with the aid of auxiliary boats, when towable booms are formed. With the aid of the invention, transport barge with a rapidly moveable structure, equipped with oil collectors is obtained, which can be attached to a towing vessel, and which in maritime conditions is stable and operable when towed. Thus a highly steerable unit is obtained for operative oil-spill-response tasks, in which the necessary hydraulics and other energy requirements of the equipment are connected from the towing vessel. In the case of an accident, the unit on operational stand-by departs for the accident site, where collection operation is started by rotating the barge's booms to the operating position.

Systems, methods, and apparatuses for detecting and collecting fluids released into a body of water are disclosed. Particularly, detection and collection of a fluid released during a petroleum exploration or production operation are disclosed. A released fluid may be detected using sensors on a submersible vehicle (SV) or a plurality of SVs operating in concert. A detected released fluid is collected in storage tanks onboard of the one or more SVs or in an external tank coupled to the one or more SVs.
