Abstract

A life raft quick support shelter system has an internal belt or plastic sheet support system (3) assembled on inflation with molded tube support frame (4) stored in a ridge tube (1) with a loop (2) for hooking to ship or helicopter lifting gear.

Description

State of the art

People who are in emergencies Liferafts can bring to safety have a dangerous one Step up to the final one Rescue to go on a ship or in the helicopter, namely the Change of location from the island to the ship or in the helicopter.

Problems with current state of the art

Those who are initially saved must either go through the helicopter may be stored individually or the dangerous one Way over the rescue net on the high ship's side in heavy seas climb at night. The helicopter has because of the longer recovery time due to the rescue of individuals, less range, or must if necessary several times to the scene of the accident to fly.

When rescued by large ships there is a risk that the climber will lose his strength and that he will enter the raging sea falls and injured himself or lost his life.

Problem solving The automatically inflatable Life rafts are made in such a way that one inside Carrying corset is located on the ridge of the roof on which the island and the rescued castaway in one stroke to the Rescue ship or the rescue helicopter is hoisted.

The possible squeezing under The island's load is prevented by an expansion tube frame.

Achieved advantages

Shipwrecked people living in life raft can be recovered from the roaring sea relatively safely if the Cable lift connection to the life raft is established. As elevator devices are suitable e.g. Helicopter winch, winches for lifeboats of large ships (Davids), net pulling devices of fishermen or similar

Another advantage: the shipwrecked do not have to keep the liferaft in position on the lifeline until everyone from the island climbed on the net. The life raft is firmly attached to the ship after clicking into the strap connected and can no longer drift uncontrolled from the ship.

By lifting the entire island with their shock absorbing The effect of the air chambers when hitting the side wall is one Relatively safe and safe tipping possible.

This applies especially to exhausted and injured persons.

The recovery of several islands in the shortest possible time This makes time possible.

system Description

The life raft is covered on the inside with a textile riser grid or a grid-reinforced carrier film, see no. 3 the sketch, equipped on the floats, see no. 5 the sketch.

After the liferaft inflates automatically, the spreader tube segments are inserted through the corner loops, see no. 4 the sketch, put together pressure-tight to a ring, or tube square or tube rectangle.

Parts of the bracing may be like this attached that they are during of inflating the liferaft itself.

First at an angle between the floor and the wall; then in the eaves area between the wall and the roof (roof kink area and wall).

The pipe bracing is intended to prevent that the island is in the mountains phase on the hook above the water bag similar contracts and squeezes the people in the life raft and hurt.

The riser grid is in a loop, see no. 1 the sketch that runs through the waterproof roof. This loop carries the entire load of the island with people in case of a fall.

The belt loop provides a buoyant ring line for safely latching the rescue hook of the helicopter or the hoist of the rescue ship, see no. 2 the sketch. The ring line is so long that it can easily be picked up by a rescue worker lowered on the helicopter cable and hooked into the rescue hook without having to hook directly into the loop on the ridge of the life raft, for example, in rough seas.

It is also easier for one person located in the life raft, the ring line e.g. before the Boarding the life raft in the hook of near the boarding to hook in the immersed lifeline. People can do this do it while sitting and have to do not get into the unsafe standing position.

Summary of the benefits achieved

The advantage of this rescue system is the relatively safe hiding of people who are in a Life raft.

From my own training experience, I know how difficult and dangerous getting out of a life raft in rough seas and wind, to e.g. to the Jacob ladder or to the rescue net on the high one Arriving ship's side wall.

The people are all rescued with a cable lift and can be safely and quickly, for example, on the deck of the rescue ship from the life raft get out. It is also safe to get out directly on the helicopter.

If the crane's lifeline or the David of the lifeboat of a ship first clicked on is controlled lifting, even in heavy seas, on the high ship wall possible because all people inside the life raft against by the air-filled floats hard knocks on the ship's wall are protected. This is all the more true if the rescued are injured and weakened people is.

Salvage can be done faster because not the people in succession from the island at raging Sea must be salvaged but everything happens with one hub per island.
