A life raft system for an aircraft, comprising a storage container; an inflatable life raft that is stored in the storage container in normal operation mode, an inflation device for inflating the inflatable life raft in an emergency mode, and a control unit for activating the inflation device in the emergency mode; wherein the control unit comprises a floatable control buoy with an activation member that is operable for activating the inflation device, wherein the floatable control buoy is provided for operation at a predetermined distance remote from an associated aircraft in an emergency mode.

A personal safety flotation device which can be carried on a person for an evacuation requiring entry into a body of water. The personal safety flotation device is for individual use comprising a carrying bag and an inflatable platform which is stowed in the carrying bag in a deflated state. The inflatable platform has a hexagonal shape allowing stability on the water and ability to connect to other inflatable platforms to create a larger surface area. The inflatable platform comprises additional safety features such as an emergency radio beacon, LED lights, light reflective strip, radar reflective pad, rope around a perimeter, and spring hooks for attachment. The carrying bag is attachable to a person and upon entry into a body of water the inflatable platform is automatically inflated with a connected compressed gas cylinder and the inflatable platform remains connected to the carrying bag via a connection strap.

A collapsible transom for an inflatable raft has a front section including two parallel front struts and a rear section including a floor portion and a collapsible support portion. The floor portion includes two parallel rear struts, and the two parallel front struts and two parallel rear struts are slidably connectable to each other by insertion into tubular end portions. The support portion is pivotally connected to the floor portion and movable between an expanded position with the support portion substantially parallel to and spaced away from the floor to a collapsed position with the support portion adjacent the floor.

Disclosed is a buoyancy tube for a life raft having: a first panel including: a first panel top edge and a first panel bottom edge, the first panel top edge defines a first repeating pattern, and the first panel bottom edge defines a second repeating pattern that is a rotated version of the first panel top edge; a second panel that has a same shape as the first panel, the first and second panels connected by a first elongated seam and a second elongated seam that are non-overlapping with one another, the first and second panels, when connected, define outer an inner boundaries of the life raft, the outer boundary defines an outer polygon having outer sides and the inner boundary defines an inner polygon having inner sides such that each of the plurality of outer sides is parallel with one of the plurality of inner sides.

An escape system comprises a slide for facilitating evacuation of from a structure to water, wherein the slide comprises at least one helical inflatable path. The or each helical inflatable path may be configured to extend generally vertically between the structure and the water. The slide may comprise a plurality of helical inflatable paths. The slide may comprise spacing means for controlling the pitch between helix turns of the or each of the helical inflatable paths. A bowsing arrangement for the slide is also disclosed.

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 inflatable motor boat with a U-shaped hull in plan view and configured to operate in shallow water. An inflatable bottom is attached to the hull and comprises an inclined longitudinal tunnel having an arc-shaped form in cross section. A portion of the tunnel is wedge-shaped with an angle of inclination from 5° to 45°. The width of the tunnel can be reduced in a rearward direction, and an upper surface of the tunnel can have a sinusoidal shape in a longitudinal section.

An orientation valve, in accordance with various embodiments, is disclosed herein. The orientation valve may comprise a first coupling portion, an insert portion, a second coupling portion, an internal cavity, and a piston. The insert portion may have a first inlet aperture and a second inlet aperture. The second coupling portion may be disposed between the first coupling portion and the insert portion. The internal cavity may be coupled to the first inlet aperture and the second inlet aperture. The piston may be disposed within the internal cavity. The orientation valve may be configured to block fluid flow from a compressed fluid source when an evacuation system is in a stored position. The orientation valve may be configured to fluidly couple the compressed fluid source and the evacuation device when the evacuation system is in a deployed position.
