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.

A life raft system including a life raft assembly including a mounting bracket having a base and an awning, an upper lateral support having a latching mechanism and deployment cable, a lower lateral support comprising a hinge-member, a self-inflatable raft having a housing, an inflator, an inflator cable, and a raft securing cable, and a cover chute. The life raft system is a residential and commercial life saving device for urban and rural area homes as well as commercial building structures that could be at risk to rising flood waters. The device may be mounted to a structure such as a home or building as a precaution. The device provides a family or group of people with the ability to flee to higher ground when disaster occurs, preventing loss of life and offering a safe exit from an affected area.

The invention discloses a lifeboat which can be used in a typhoon day. The boat includes a hull. The hull is provided with a helical gear space symmetrically on the lower side of the transmission space. On the left side of the energized magnet, when the hull is stabilized, the motor needs to be automatically loosened and taken up to stabilize the hull. At the same time, the fan blades can be rotated to drive the ship forward or backward by the rotation of the helical gear, which can fully convert the excess electrical energy into The mechanical energy can also slide the rotation axis of the fan blade down to the fixed connection with the first rotating rod. When a person steps on the pedal, the mechanical energy generated can drive the fan blade to rotate to make the boat move forward or backward, and a life buoy is also designed. Insufflation function and push-out lever, which can automatically throw out the inflated life buoy for rescue when rescue is needed.

An arrangement for evacuating people from an offshore installation having a lifeboat and an arrangement for a free-fall based lifeboat launch with a tilted ramp characterised in that the ramp of the free-fall launching arrangement is mounted on the ramp axle, has a wire rope winch and is movable. The power hydraulic mechanism of the ramp consists of an arrangement of the two lower and upper identical hydraulic cylinders, a gear bar, a gearwheel of the ramp axle and the additional gearwheel of the gear bar. Piston rods of hydraulic cylinders are arranged on two opposite sides of the gear bar and are connected to the ends of the gear bar. The gear bar engages with the additional gearwheel engaging with the gearwheel of the ramp axle.
