Definitions

  • the present invention relates to an emergency release device for equipment fitted on a vessel or an offshore installation.
  • the above mentioned object is achieved with an emergency release device as given in the independent claim 1.
  • the emergency release device comprises at least one detonator capsule arranged to be placed about, or to, a securing part for said equipment's attachment to the base, as the securing part is arranged to be damaged or destroyed in that the detonator capsule comprises a remotely triggered explosive charge.
  • Said detonator capsule can comprise a through-going vertical opening in which the detonator capsule is arranged to be placed about a bolt for the equipment's securing part to the base, and that said explosive charge is arranged in said opening. Furthermore, the detonator capsule can comprise a trigger mechanism connected to said explosive charge where the trigger mechanism is arranged to detonate the explosive charge.
  • the detonator capsule preferably comprises a detonator channel that runs from the trigger mechanism and into said opening with the explosive charge.
  • Said detonator capsule is preferably arranged to be placed about said bolt on the topside of the securing foot of the equipment, or about the bolt between the securing foot and the base or about the bolt on the underside of the base.
  • the trigger mechanism is preferably connected, via an activator cable, to a remotely placed activator comprising a number of connections.
  • Said detonator capsule comprises an evacuation channel.
  • Said object can also be achieved with an emergency release device as described in the dependant claim 8, where the emergency release device comprises at least one detonator part arranged to be placed in a securing bolt to said equipment' s fastening to the base, as the securing bolt is arranged to be damaged or destroyed in that the detonator part comprises a remotely triggered explosive charge.
  • the emergency release device comprises at least one detonator part arranged to be placed in a securing bolt to said equipment' s fastening to the base, as the securing bolt is arranged to be damaged or destroyed in that the detonator part comprises a remotely triggered explosive charge.
  • the securing bolt preferably comprises an axial cavity that holds the detonator part, in which the detonator part is connected to a trigger mechanism arranged to detonate the explosive charge.
  • Said trigger mechanism is preferably connected via an activator cable to a remotely located activator comprising a number of connections .
  • Said securing bolt can comprise a detonator channel that runs from the trigger mechanism and into said cavity containing the explosive charge.
  • Fig. 1 shows a detonator capsule of an emergency release device according to the present invention.
  • Fig. 2 shows a section through the detonator capsule shown in figure 1.
  • Fig. 3 shows a section of the detonator capsule secured between equipment and the base.
  • Fig. 4 shows a second embodiment of an emergency release device according to the present invention.
  • the detonator capsule is fastened around the bolt of the securing foot, but dependent on the equipment, it can be imagined that the detonator capsule can be placed on or around the securing foot itself for damage or destruction of the foot itself.
  • securing part must be understood the securing foot of the equipment (or another securing appliance) or the bolt(s) that secures the foot to the base .
  • Figure 1 shows a detonator capsule 12 of an emergency- release device 10.
  • a body for example, a plate-formed body which is arranged to be placed about, for example, a securing bolt for fastening of equipment to a base.
  • the detonator capsule can be placed about the bolt on the top side of the securing foot of the equipment, about the bolt between the securing foot and the base or about the bolt on the underside of the base.
  • the detonator capsule 12 comprises, in that embodiment, for example, a plate-formed body which comprises a through-going vertical opening 32 that can surround a bolt 18 to a foot of the equipment that is fastened to a base 26 on the vessel.
  • a plate-formed body which comprises a through-going vertical opening 32 that can surround a bolt 18 to a foot of the equipment that is fastened to a base 26 on the vessel.
  • the detonator capsule 12 is placed between the foot 24 of the equipment 30 and the base 26.
  • An explosive charge 14 is placed in said opening 32 where the explosive charge is arranged to break the bolt on detonation so that the equipment to which the foot is secured becomes loose from the base.
  • the opening 32 can be fitted with sleeves or the like to provide a close fit around the bolt 18. Consequently, an emergency release device can be arranged to one or more of the equipment' s securing parts to the base.
  • the explosive charge 14 is connected via a channel 22 to a trigger mechanism 16 which is arranged to detonate the explosive charge.
  • a trigger mechanism 16 which is arranged to detonate the explosive charge.
  • an evacuation channel 20 can be provided in the other end of the detonator capsule for example.
  • the trigger mechanism 16 is preferably connected via an activator cable (not shown) to a remotely located activator, for example, placed on the bridge or at a position where the equipment is operated on the vessel.
  • an audible alarm can be provided that sends out a warning a given time period before the explosive charge is activated so that the crew can get to safety.
  • the activator (the remotely located trigger) can comprise triggering equipment to be connected with a number of detonation capsules.
  • Figure 4 shows a second embodiment of an emergency release device 50.
  • the bolt 40 that secures the equipment to the base has a cavity 46 that holds a detonator part 42 with an explosive charge.
  • the detonator part 42 is connected via a channel 44 to the trigger mechanism 16. Additionally the trigger mechanism is connected to an activator as described above.
  • the trigger mechanism, activator cable and activator are made up from known components and are considered known to a person skilled in the arts and will therefore not be described in more detail.
