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.

A life raft may comprise a border tube and a canopy support tube coupled to an outer portion of the border tube. A first orifice defined by the canopy support tube is aligned with a second orifice defined by the border tube. A diameter of the first orifice is less than a diameter of the second orifice.

Provided is a maritime overboard locator system for use in locating and rescuing a person or asset that has fallen overboard into a body of water. The system includes a locator attached to a person or asset that is activated manually or automatically upon immersion in water. The apparatus emits light, sound, radio, or any combination thereof. The locator is detected by one or more detectors onboard a boat, ship, vessel, or structure. The detectors detect a unique signal that is assigned to each person/asset. Once detected, the detector sends an overboard alert and deploys an unmanned aerial or underwater drone. The drone can include an inflatable life preserver or life raft and a tether cord that helps the person to remain afloat until rescue can be accomplished.

An evacuation system may comprise a first plurality of tubes configured to inflate by an aspirator and pressure cylinder upon deployment from an aircraft. The evacuation system may further comprise a second plurality of tubes coupled to the first plurality of tubes. The second plurality of tubes may be configured to be in deflated state when the evacuation system is in a slide configuration. The second plurality of tubes may be configured to be in an inflated state when the evacuation system is in a raft configuration.

The invention encompasses fire-escape models of off-shore rigs with emphasis on a ‘Detachable Island Rig’ (DIR) with a bottom air capsule. The DIR unlocked from permanent underwater basement, is steered away upon a rig-fire, while also sinking and rising the unit controlling a fire. The basement's fire-escape for the crew with devised ‘water-seal’ also serves as fire-escape model for Jack-up rigs. Converging ‘spray-walks’ to a ‘spray-room’, ‘water-tracks’ with ‘track-drives’, or simpler ‘spray-drives’ are evacuation accessories. Other gas-fire protective measures include gas-chasing fans and pressured air-circuits, while canisters of soda lime absorb CO2 and CO. The wheeled ‘life-boats’ and ‘lift-boats’ are remotely let out boarded/un-boarded without collision injury. Strut-burlaps air-dropped from hovering cranes, drones or helicopters can smother a rig-fire. Countering devising for water-wind turbulences is herein actuated for floating rigs without legs. Vital needs like safe evacuation and fresh air supply are herein devised as affirmed provisions.
