Definitions

  • the present invention relates to a device and a method for rescuing personnel from waters. More particularly, the invention relates to rescuing personnel from frigid and hostile seas without the need for participation by the individual(s) being rescued.
  • hypothermia When personnel fall into hostile and frigid waters, particularly at offshore facilities, the cold waters cause hypothermia to set in very quickly. Typically, such hypothermia occurs in 8 to 15 minutes without survival suits and in about 45 minutes to slightly over one hour with survival suits. Thus, survival depends upon removing such personnel from the sea as quickly as possible.
  • US Patent US-A-2,557,079 describes a rescuing device comprising a frame and a cradle connected thereto.
  • the device is adapted to be raised or lowered onto the water from a davit by means of a conventional boat fall.
  • a device for rescuing personnel from water comprising a horizontally and vertically movable boom mounted on a rescue structure and a net characterized in that an elongated rigid member is interconnected to the boom, the elongated member being freely slidable and inclinable with respect to the boom and being normally orientated vertically; a buoyant means is operatively connected to the elongated member for floating on water, the net being connected to the lower end of the elongated member and disposed below the buoyant means; and locking means is provided for selectively locking the elongated member relative to the boom.
  • the crane When personnel are in the water, the crane is operated to move the boom from an inboard position to an outboard position, and the elongated member is permitted to move downwardly with respect to the boom such that the buoyant means floats on the water. At this position, the net extends beneath the float in the water. The net is moved forwardly by operation of the boom (and/ or boat) such that the individual(s) are within the net. The operator then manipulates the boom to hoist the individual(s) out of the water and deposit the individual(s) on the rescue structure.
  • the present invention provides for scooping personnel out of the water without such personnel needing to assist in their own rescue. Such rescue can occur quickly and safey to thus increase the chance of the rescued personnel to survive.
  • a rescue device having a buoyant means or a float 15 which is freely floatable on the surface of the water 20.
  • Attached to the float 15 is a high tensile strength elongated member or pipe 10 which is slidable in a guide 9.
  • a frame 12 has four arms 22 extending outwardly from a frame support bracket 17, and the bracket 17 is connected to the pipe 10.
  • a rescue net 13 is attached to the outer ends 24 of arms 22 of the rescue net frame 12.
  • the net 13 has a plurality of weights 14 secured thereto to maintain the curved shape shown in FIG. 1 below the water line 20.
  • the net 13 extends upwardly at the rear end and sides thereof to a level 26 above the water line 20. Such level 26 is defined by the net-to-arm connections 24.
  • the front end 28 of the net 13 is opened such that the front end 28 extends downwardly below the water line 20 as shown in FIG. 1.
  • the pipe 10 has a safety stop 16 at the upper end thereof having an outer dimension larger than the guide 9 such that the pipe 10 will stop sliding downwardly when the safety stop 16 abuts the top end of the guide 9.
  • the guide 9 is attached to a gimbal frame 8 which permits the pipe 10 incline freely in any direction.
  • the pipe 10 is vertically movable through the gimbal 8. Since the pipe 10 is freely movable in any direction and vertically, means are provided for compensating for the motion of the boat 1 with respect to the water line 20 whereby the float 15 and the net 13 follow the contour of the water line 20.
  • FIGS. 1 and 2 contemplate the use of a brake system such as shown in FIGS. 8 and 9 for locking the pipe 10 with respect to the guide 9.
  • the gimbal 8 is also slidable freely along guide rails 6.
  • a safety stop 30 is provided at the outer end of the guide rails 6 for abutting contact with the gimbal 8.
  • the gimbal 8 is lockable relative to the guide rails 6 by means of hydraulic locking pins (not shown), actuated through hydraulic line 33.
  • the guide rails 6 are connected to rotary actuator system 11 such as will be described hereinafter with reference to FIG. 12.
  • the swing head 11 is mounted on the boom 32 of a hydraulic crane 2.
  • the crane 2 has an operating platform 4 mounted on a rotatable table 3.
  • a hydraulic ram 5 is connected to the boom 32 for moving the arm 32 upwardly or downwardly.
  • the crane 2 mounted on the work or rescue boat 1 can be any standard or specially adapted crane capable of lowering an raising the entire rescue device quickly into and out of the water.
  • buoyant means are in the form of spaced elongated floats 40 which function as pontoons freely floatable on the surface of the water 41.
  • a frame 42 interconnects a high tensile strength elongated member or pipe 43 by means of four arms 44 extending outwardly to the ends of the floats 40.
  • FIG. 6 shows a side elevational view of one of the floats 40.
  • FIG. 7 shows the frame 42 in an expanded and closed position.
  • a rescue net 45 is attached to the outer ends of arms 44 of the frame 42.
  • the net 45 has a plurality of weights 46 secured thereto to maintain the curved shape shown in FIG. 4 below the water line 41.
  • the net 45 extends upwardly at the rear end and sides thereof to a level 47 above the water line 41.
  • the front end 48 of the net 45 is opened such that the front end 48 extends downwardly below the water line 41 to provide a generally semicircular front end opening.
  • the pipe 43 extends upwardly through a gimbal and brake mechanism 48, and has a safety stop 49 at the upper end thereof having an outer dimension larger than the opening through the gimbal and brake mechanism 48.
  • the pipe 43 will stop sliding downwardly when the safety stop 49 abuts the top of the gimbal brake and mechanism 48 as shown in dashed lines in FIG. 4.
  • FIGS. 8, 10 and 11 A suitable gimbal system 50 is shown in FIGS. 8, 10 and 11.
  • the gimbal system 50 has an outer elongated rectangular frame 51 pivotable about an axis defined by opposing posts 52, 53 and an inner elongated rectangular frame 54 pivotable about an axis defined by posts 55, 56.
  • the outer rectangular frame 51 is mounted to spaced gimbal support arms 57, 58.
  • the pipe 43 has a rectangular cross-section and is freely vertically movable through the inner rectangular frame 54 of the gimbal system 50.
  • the gimbal system 50 permits the pipe 43 to incline freely in any direction.
  • the combination of the pipe 43 being freely vertically movable and being freely inclinable in any direction provides compensation for the relative motion of the boat 60 with respect to the water line 41 and thereby permits the floats 40 and net 45 to follow the contour of the water line 41.
  • the gimbal and brake mechanism 48 includes a brake system 62 mounted above the gimbal system 50.
  • the brake system 62 has a hydraulic cylinder 64 which actuates a piston 66 in the directions shown by the arrow heads to move a plate 68 and an attached brake pad 70.
  • the piston 66 is moved to the left as viewed in FIG. 9, the pipe 43 is secured between the brake pad 70 and an opposing brake pad 72 mounted on a fixed plate 74.
  • brake pad 70 is moved away from the pipe 43 permitting the pipe 43 to freely move through the brake system 62.
  • a suitable cylinder is the Flairline Hydraulic Cylinder, Series H 4" Bore X 1" Stroke, 3447.4 kPa (500 psi) pressure, 2721.6 kg (6,000 Ibs.) total load.
  • the gimbal and brake mechanism 48 is connected by means of a rotary actuator system 80 to a boom 82 of a crane 84 mounted on the boat 60.
  • a hydraulic hose 86 for the brake system 62 extends along the boom 82.
  • Another hydraulic hose 88 for the rotary actuator system 80 also extends down the boom 82.
  • the gimbal system 50 is mounted by bringing plate 92 into contact with a plate 94 and securing bolts 90 through the plate 94.
  • a shaft 96 extends through the plates 92, 94 and is secured by nut and bolt arrangements 98 to the spaced gimbal support arms 57, 58.
  • the shaft 96 is connected at its other end to a spline 100, and is rotatable within a bearing 102 by operation of a rotary actuator 104 which is connected to the spline 100.
  • the rotary actuator 104 is responsive to hydraulic pressure via hose 88 through inlets 106.
  • the rotary actuator system 80 thus provides for applying a rotary motion to the pipe 43 and net 45 about an axis as defined by the longitudinal axis of the boom 82.
  • a suitable actuator is the ROTAC Rotary Actuator, Model 26R-62, Double Vane 100° rotation.
  • an operator would operate the hydraulic crane 84 to move the net 40 from its inboard position as shown in dashed lines in FIG. 3 to an outboard position as shown in solid lines in FIG. 3.
  • the pipe 43 is locked with respect to boom 82 by means of the hydraulically powered brake system 62.
  • the brake system 62 is then released to permit the pipe 43 to slide downwardly through the gimbal system 50 until floats 40 reach their buoyant position.
  • the boat 60 approaches along side the individual(s) at a suitable reduced speed and at a suitable distance which may be in the order of approximately ten meters from the side of the boat 60 to the center of the net 45.
  • the net 45 is moved forward by operation of the crane and/or boat such that the individual(s) are positioned within the net 45 through its open front end 48.
  • the operator may also use the rotary actuator system 80 to scoop the net 45 under the individual(s).
  • the operator then locks the brake system 62 to fix the pipe 43 with respect to its boom 82.
  • actuating a hydraulic ram 110 the individual(s) are quickly hoisted out of the water, and the crane 84 is rotated to the position shown in dashed lines in FIG. 3 to quickly deposit the individual(s) on the deck of the boat 60.
