Definitions

  • the invention relates to a rescue device for floating or stationary platforms or stations, such as. B. oil rigs, which can be dropped or anchored in the vicinity of such a system under water until an emergency occurs and releases a life raft floating on the water surface after release.
  • the invention has for its object to provide a rescue device which are kept substantially stationary under water even at greater depths and can be operated in an emergency to suspend a life raft that, although there is no access under water, regular maintenance of all parts enables and that can be lowered undamaged after installation in the ready position over water and without opening to a greater depth.
  • the rescue device comprises a base part and a container attached thereon, which can rise under its own buoyancy and releases a self-inflating life raft near the water surface, and furthermore devices for holding the container on the base part and for releasing and preferably also means with which a Floating of the base part with a container arranged on it is made possible.
  • the base part When the rescue equipment is lowered onto the sea floor, the base part forms a foundation. It is designed as a heavy plate or frame, which holds the container in a ready position against its buoyancy on the sea floor. However, the base part can also be arranged above the sea floor, for example on a holding rope of a platform, at a depth in which it does not interfere with shipping traffic and in which it is hardly exposed to the wave movements of the sea.
  • the container is preferably spherical and consists of two half-shells which are made of fiber-reinforced plastic.
  • a ring made of a relatively strong plastic is located between the flanges of the two half-shells.
  • On both sides of the ring there is at least one groove which receives a seal, for example a lip seal.
  • the brackets can be released. They have levers which are held in a position which compresses the flanges by means of a tension cable running above the level of the flanges. On the clamp or preferably on the levers, there are holding lines which hold the container on the base part and which can be released, for example, by a pivoting movement of the lever. By means of a release mechanism, one end of the tensioning cable clamped in it is released or at least released so far that the levers of the clamps pivot downward.
  • the base part, half-shells and the life raft which inflates after the container has been opened preferably remain connected by a tether, so that the life raft remains close to the platform.
  • the base part is provided with a number of floating bodies, which are stowed away in the folded state and are released by compressed air upon a signal.
  • the size of these elastic bubbles should be chosen according to the weight of the base part.
  • Differential pressure valves are provided on the floating bodies, which keep the volume of these bodies approximately constant during the ascent hold and thus avoid their inadmissible expansion. By floating, the entire rescue device can be brought to the surface of the water and taken on board a ship to carry out maintenance work and functional tests.
  • the rescue device can be actuated to release the container or to float the entire device by means of acoustic or electrical signals, for example also via a cable connection to the platform.
  • the container of the rescue device shown consists of the two half-shells 1, between whose flanges 21 an intermediate ring 5 is arranged.
  • This container is held on the base part 2 by holding lines 7, which can also be regarded as a foundation.
  • Four brackets 4 press the half-shells 1 against the intermediate ring and have levers 14, which are tensioned by a tension cable 16 under their tension Be held in position.
  • the holding lines 7, which can be adjusted via turnbuckles 11, engage the levers 14.
  • the levers 14 pivot outwards and detach themselves from the holding lines 7, so that the container can rise through its own buoyancy.
  • the foundation 2 On the foundation 2 there is a rope drum 17, via whose rope 27 the ascending container and the life raft contained therein remain connected to the foundation.
  • the foundation 2 has receiving spaces 32 for folded floating bodies (not shown).
  • the control devices 9 and possibly the signal receiver for the floating of the entire rescue device and for the trigger 6 for releasing the half-shells 1 are also accommodated in a watertight container there.
  • a cable connection, not shown, can run between the control unit 9 and the trigger 6.
  • a water detector 8 can be arranged in the interior of the lower half-shell 1, which is also connected to the control device 9 by a cable and which triggers the emission of a signal if water collects there.
  • the clamp 4 engages with a fixed leg from below on the outside of the flange 21 of the lower half-shell 1.
  • a hinge pin 22 is arranged, on which a lever 14 can rotate, which with its lower leg presses on the outside of the flange 21 of the upper half-shell from above, so that both flanges 21 are pressed against the intermediate ring 5 will.
  • the tensioning cable 16 extends through a hole or a hook-shaped recess at the upper end of the lever 14 in the tensioned state.
  • On the lever 14 there is a hook 23 which is engaged by an eye connected to the tether 7 by means of a turnbuckle 11. If the tension cable 16 is released, the lever 14 pivots outwards and downwards. The hook 23 releases the tether 7 and at the same time the short leg of the lever 14 is pivoted into a position in which the upper half-shell 1 can separate from the intermediate ring.
  • the pressing force on the flanges can be adjusted by means of clamping screws 15.
  • the clamping screws 15 act on metallic washers 25 in order to avoid damage to the plastic of the flanges 21.
  • a flat metal rod 24 which is fastened to the intermediate ring by means of a screw 18 and can be connected to the clamp part 4 in a manner not shown, so that the latter on the intermediate ring 5 when the container opens and the lower half-shell 1 remains.
  • An elastic lip seal 12 is inserted in at least one annular groove on each side of the intermediate ring 5.
  • a permanently plastic sealing compound 13 is introduced into a groove in the ring 5 on the outer edge of the sealing joints.
  • the trigger 6 can be attached to one of the levers 14, the upper end of which is designed in a suitable manner for this purpose.
  • a pyrotechnic device for example, is suitable as a trigger, which ejects a piston in response to an electrical impulse, which releases a clamping lever which firmly clamps the cable, which is not shown in the drawings.
  • the two half-shells initially remain in close contact with one another under the effect of the external water pressure.
  • a device not shown, is affected, whereby the valve of a compressed air bottle in the container opens, releases compressed air through which the life raft is inflated, and thereby the half-shells 1 are separated from each other when the water surface is reached, so that The life raft 40 can unfold to its full volume on the water surface without delay.
  • the half-shells 1 expediently remain attached to the tether 27.
  • a number of rescue devices are arranged on the seabed around a platform 50, so that in an emergency and even in unfavorable weather there are always enough life rafts 40 available for people who have to leave the platform 50.
  • an intermediate ring 5 is dispensed with, so that the flanges of the half-shells 1 lie directly against one another, including suitable sealing agents, and are pressed together by the external water pressure and the clamps 4.
  • the brackets are preferably attached to the lower half-shell.
  • the sealing means enclosed between the flanges are preferably an elastic, soft sealing material in an outer annular surface, which is effective in the low pressure range, and a hard sealing material in an inner annular surface for sealing in the high pressure region.
