Provided is a shelter floating device which enables an amphibious shelter to stably float on a surface of waters. The shelter floating device is provided on a lower surface of the amphibious shelter, and has a protruding floater, a Scott Russell mechanism unit, and a jack (operating means). The protruding floater is connected to the jack through the Scott Russell mechanism unit, while at the same time, being supported by a support device. The jack is fixed to the lower surface of the amphibious shelter. Consequently, by operating the jack, the protruding floater projects itself to an outside of side surfaces of the amphibious shelter along a perpendicular direction.

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.

A stretcher that can be rolled up may comprise at least two straps for securing a person in a longitudinal direction of the stretcher. The at least two straps for securing the person in the longitudinal direction of the stretcher are disposed such that the at least two straps are fastened above a first region. The first region may be configured to accommodate shoulders of the person. The stretcher may further comprises a foot plate that is adjustable in the longitudinal direction of the stretcher. In addition, a deployable buoyancy device may be mounted on the stretcher. The deployable buoyancy device may be fastened in a second region on the stretcher, wherein the second region is configured to accommodate the person's neck. The deployable buoyancy device may have a tubular configuration, and the deployable buoyancy device may be connected in the second region to the at least two straps for securing the person in the longitudinal direction.”

An all-weather maintenance system for an offshore wind turbine maintenance program includes a maintenance capsule for transporting tools, parts and maintenance personnel to and from respective wind turbine towers, a maintenance vessel with a capsule support apparatus for transporting capsules supported on board by the capsule support apparatus to and from respective wind turbine towers, and a crane assembly with a trolley for transporting capsules between the respective wind turbine towers and the maintenance vessel.

A survival helmet device for use in combination with a survival suit includes a helmet, inhale and exhale control valves, and at least one inflatable air cavity packet secured to the survival suit for selectively controlling the air supply and buoyancy of the survival helmet device and the survival suit.

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.
