The invention belongs to the technical field of ships, and relates to an aerogel heat preservation ship rescue cabin, which comprises a cabin body. The cabin body and arc-shaped plates are made of aerogel materials. Water pumping devices are symmetrically sleeved outside the cabin body near two sides. A straight pipe is connected between the two water pumping devices. Strip-shaped water outlet holes are formed at front and rear sides of the straight pipe in a penetrating manner. A heat insulation plate is sleeved on the cabin body and hollow, and two ends thereof are communicated with the water outlet holes at front and rear sides of the straight pipe. Multiple drainage holes are formed in the inner wall, opposite to the cabin body, of the heat insulation plate in a penetrating manner. Multiple evaporation holes are formed in the top of the heat insulation plate in a penetrating manner.

According to one embodiment, an apparatus includes an outer shell having a shape substantially similar to a weapon. The outer shell is configured to be coupled to an aircraft at a weapon attachment point. The apparatus further includes one or more electrical connections configured to be coupled to a weapons control system of the aircraft. The apparatus further includes a life support package comprising an inflatable raft and a stabilization system configured to stabilize the inflatable raft in water.

An autonomous navigation type marine buoy includes: a buoy body consisting of a floating body; an internal sensor; a detection unit that receives a GPS signal and information of the internal sensor; an on-water exploration unit that explores a state on a sea; an underwater exploration unit that explores a state under the sea; a determination unit that creates a navigation plan for the buoy body; a propulsion unit that propels the buoy body; a navigation control unit that performs drive control of the propulsion unit so that the buoy body navigates according to the navigation plan; a power generation unit; a power storage unit; a communication unit that communicates with an outside; an emergency signal unit that receives a distress signal and specifies a transmission position of the distress signal; and an evacuation room that accommodates a victim, in which the autonomous navigation type marine buoy has an autonomous navigation mode of performing autonomous navigation to a set position on the sea, a home position mode of autonomously holding a home position at the set position on the sea, and a rescue mode of performing autonomous navigation to the transmission position of the distress signal on the sea when the distress signal is received.

Disclosed is a capsular-type underwater release lifeboat that can be operated in davit mode, freefall mode and underwater mode. The lifeboat comprised of an outer shell, and fitted inside with engines that aid in forced and normal propulsions of the lifeboat. Two air pockets are arranged in both the ends of the outer shell to sustain underwater pressure and to aid increased buoyancy of the lifeboat. A fixed Emergency Positioning Indicating Radio Beacon (EPIRB) is provided inside the lifeboat for rescuers to easily locate the survivors and a double water tight entrance door is formed on the top portion to resist the underwater pressure. The present invention also provides a method for releasing the lifeboat underwater. The reinforced lifeboat discussed herein shall be deployed on the sea and also underwater in order to rescue the people during a disaster in the sea vessel.

A survival craft for maritime evacuation of passengers and crew members from a vessel or an offshore facility is disclosed. The survival craft has a hull, predominantly made of non-rigid inflatable tubes and one or more shells, the hull has a length, a width and a centerline, a bow and a stern. The survival craft further comprises a first pair of engine-powered propulsion means arranged at the stern on opposite sides of the centerline, and a second pair of engine-powered propulsion means arranged at the bow on opposite sides of the centerline, each engine-powered propulsion means has a propeller or a water jet, wherein a horizontal angle of each propeller or water jet of each engine-powered propulsion means can be independently set in relation to the centerline.

A maritime evacuation system to be installed on a vessel or offshore facility comprises a storage unit to be installed on the vessel or offshore facility, at least two survival crafts, each having a hull, predominantly made of non-rigid inflatable tubes and one or more shells, the survival crafts being configured to be stored in the storage unit in a deflated state, each survival craft comprises at least two engine powered propulsion means, the maritime evacuation system further comprising a central control unit being operatively connected with each engine powered propulsion means, wherein the central control unit is configured to observe the condition of and test the readiness of each engine powered propulsion means at predetermined intervals so that it is continuously monitored if the maritime evacuation system meets the requirements for being ready for rescue.

An unmanned lifeboat 1 has a hull 2 with a transom opening 3, a fo'c'sle 4 closed by a rounded top deck 5, providing accommodation 6 for survivors. The aft deck as such is generally U-shaped with a cut-out 16 open at the transom 17, which is vestigial with two small port and starboard parts. Within the cut-out is a boarding assistance ramp 18. This is level with the aft deck at its forward end and slopes down to the transom. It extends aft of this by a few of feet—say about 1 m—to enable survivors to swim and crawl onto it.

For guidance to reach the vicinity of the survivors, the lifeboat is equipped with a communication apparatus including a receiver 32 for receiving survivor location data. In addition, the navigation apparatus with which the lifeboat is equipped includes a GPS system 33 of its own, a compass 34.

The ship rescue cabin, the rectangular sealing box body are divided into large and small sealing boxes by the partition board, and both the partition board and the small sealing box are provided with sealing doors and locking handles. The small seal box has an exhaust valve switch, the large seal box has three short adapters, and the bottom plate has holes and rubber squares. The edge of the bottom plate is provided with an extension piece, and the extension plate is provided with holes. The bottom plate of the adjacent small sealing box is also provided with holes. There is also a square frame corresponding to the slightly larger bottom surface of the sealing box with screw rods.

The built-in system for testing the sprinkler system of a lifeboat is characterized in that it has a water tank (17) connected to a pipeline for the water from the water installation of the marine facility (14) which pipeline is equipped with a sprinkler system pump (2). The pipeline for the water from the water installation of the marine facility (14) has a valve for the water from the water installation of the marine facility (15) and is connected to an outboard water inlet pipe of the sprinkler system (4), which pipe has an outboard water valve (5). At a connection point (16), the pipeline for the water from the water installation of the marine facility (14) is connected to the outboard water inlet pipe of the sprinkler system (4). The connection point (16) that connects the pipeline for the water from the water installation of the marine facility (14) to the outboard water inlet pipe of the sprinkler system (4) is located between the outboard water valve (5) of the outboard water inlet pipe of the sprinkler system (4) and the sprinkler system pump (2).
