A weather mitigation assembly for reducing the surface temperature of the ocean to mitigate developing oceanic weather systems includes a buoy that is floated on the ocean. An air pump is coupled to the buoy and a plurality of tethers is each coupled between the buoy and the ocean floor for keeping the buoy in a selected spot. A network of bubble pipes is each laid along the ocean floor. A supply pipe is fluidly coupled between the air pump and the network of bubble pipes. In this way the air pump can pump air into the network of bubble pipes. Each of the bubble pipes releases air bubbles upwardly toward the surface of the ocean urge cool water on the ocean floor upwardly toward the surface of the ocean. In this way the surface of the ocean can be cooled thereby reducing thermal energy available for developing weather systems.

A buoy comprising a hydrocarbon processing facility for processing production fluids received from an offshore well, the facility being disposed in a portion of the buoy that is submerged below the waterline, has a pressure relief channel for venting gas above the waterline. The pressure relief channel is in fluid communication with a chamber in the buoy which may contain the processing facility, or other equipment presenting an explosive hazard, and is the only conduit through which high pressure is exhausted. In particular, the pressure relief channel can contain the effects of an over-pressurisation event within the chamber such as ignition of flammable gas, and mitigate structural damage to the buoy.

A pressurization processing system that performs pressurization processing on a target by immersing the target in the sea or a lake, includes a housing body that is configured to house the target, a buoyancy body that is configured to float the housing body, a weight body that has a specific gravity greater than that of seawater or lake water, and a separation mechanism that separably connects the housing body and the weight body. In the system, the buoyancy body includes a housing bag having water permeability, and the housing bag houses a plurality of hollow glass spheres, and is immersed in the seawater or the lake water so that a space between the plurality of hollow glass spheres housed in the housing bag is filled with the seawater or the lake water.

A floating storage box includes a box that may contain objects. A first float is coupled around the box. The first float is comprised of a buoyant material to float the box when the box is placed in water. A pair of wheels is each rotatably coupled to the box to roll along a support surface. A pair of legs is coupled to the box to abut the support surface. A first lid is hingedly coupled to the box such that the first lid selectively closes the box. A second lid is hingedly coupled to the first lid.

A system includes a fuel burner disposed within a buoy, and at least one fuel tank coupled to the fuel burner. The fuel tank preferably contains ethanol or propane. The system comprises either a thermoelectric generator or an electrical generator mechanically coupled to a heat engine. The ethanol or propane is burned to generate electric power. At least a portion of the electric power that is generated is stored in a battery system so that the system can provide peak levels of electric power consumption that are relatively large. The system can be used in autonomous marine applications.

Provided with a weight release device capable of being operated in deep sea same as the conventional weight release device without accompanying a mechanical operation at all to avoid troubles of mechanical operation occurred in the conventional weight release device. The weight release device includes a housing fixed to the underwater observation device; a thread made of thermoplastic resin; electric heater portions; a weight support plate; a locking member of the thread made of the thermoplastic resin; and a ring for hanging the weight. The thread made of the thermoplastic resin is arranged from a start point housed in the housing, arranged to pass through the first electric heater portion, locked to the locking member of the thread made of the thermoplastic resin, arranged to pass through the second electric heater portion housed in the housing, and returned to an end point housed in the housing. The ring for hanging the weight is fixed to a lower surface of the weight support plate. The weight is released only by conducting an electricity through the electric heater portion to release the weight for floating the underwater observation device.
