  • Patent number: 8215889
    Abstract: A high current cursor comprises a outer frame in which a center carriage travels. The center carriage travels between the top and bottom of the outer frame. Movement of the center carriage is limited within the outer frame constraints and its own locking mechanism. Center carriage carries a bend restrictor for an umbilical or lift line. When the center carriage travels down to a predetermined position within the high current cursor, equipment is allowed to exit the high current cursor or is retrieved back into the high current cursor when the bend restrictor reaches a predetermined position within the outer frame, e.g. at its lowest point, allowing dispersal and/or retrieval without obstruction back to a fixed recovery point.

  • Patent number: 7438016
    Abstract: The invention relates to methods and devices for launching into the water, from a height H greater than a predetermined height hmax, a life-saving object designed to be able to be launched into the water in free fall from this maximum height hmax. One end of a halyard is fixedly hooked to the life-saving object or to the launch site; the halyard functionally cooperates respectively with the launch site or the life-saving object so that the life-saving object falling by gravity is braked on and/or by the halyard over at least one part (H-hmax) of its drop height. By controlling the braking effect, the life-saving object, falling from the height H in a braked manner over at least one part (H-hmax) of this height hits the surface of the water (5) with a kinetic energy not exceeding that which it would have at the end of a non-braked free fall from at most the height hmax.

  • Patent number: 7159527
    Abstract: A mooring system (28) of a floatable unit (20), such as life raft or platform, the floatable unit (20) having a first side (21) facing a vessel side (22) and a second side (23) facing away from the vessel side (22). The mooring system (28) comprises at least two back springs (2) which are in connection with the first side (21) of the floatable unit (20), and at least one strap (1) which is in connection with the second side (23) of the floatable unit (20), the back springs (2) and the strap (1) being connected to the vessel (30). The back springs (2) are adapted to control the floatable unit (20) in a longitudinal direction in relation to the vessel (30), and the strap (1) is adapted to control the floatable unit (20) in a transverse direction in relation to the vessel (30). The floatable unit is held in secure and fixed position alongside the vessel side, thereby enabling people evacuating from the vessel to enter the floatable unit without any high risk of injury or damage.

  • Patent number: 6102762
    Abstract: A marine escape system has a passage extending between an evacuation point on a vessel and an inflatable life raft. The passage is arranged vertically and is connected to a succession of hoops. The connection between at least one of the hoops and the life raft is achieved by flexible elongate members of differing flexibility These are held in tension so that, as the life rafts move on swell, the passage extends and retracts from the lower end first. This allows the passage to have only one exit which can be within a life raft so that persons can evacuate from the ship without ever being exposed to the elements. The passage may include a helical tube or a tube with angled panels.

  • Patent number: 5499596
    Abstract: A marine vessel launch apparatus utilizing cradle wedges that are released by explosive triggers. The cradle wedges are located above each skidway and directly support the vessel. The cradle wedge is shaped and sized to provide a direct means of connecting the cradle wedge to the vessel tieback/support. The tieback/support for the cradle wedge is rigidly attached to the skidway. The tieback/support and cradle wedge are held together with bolts and frangible nuts. Explosive charges are used on the frangible nuts to release the cradle wedges from the tieback/support and launch the vessel. Jacks provide positive horizontal pressure on the cradle wedges to break static friction between the cradle wedges and skidways to initiate vessel motion down the skidways and into the waterway.

  • Patent number: 5301630
    Abstract: A rescue ramp (10) for use by a watercraft (11) includes a laterally extending first inflatable tube member (14) attachable to the watercraft (11). Second spaced inflatable tube members (15) are connected at one end to and extend longitudinally from the ends of the first tube member (14). A third inflatable tube member (16) is connected between the second tube members (15) near the other end thereof and is adapted to be positioned in the water. A ramp (17) is connected to the first and second tube members (14, 15) so that when the rescue ramp (10) is inflated and attached to the watercraft (11), a person may traverse from the water to the watercraft (11) or from the watercraft (11) to the water. The first tube member (14) is attached to the watercraft (11) by means of a girt bar (23) releasably mounted on the watercraft (11). The girt bar (23) is connected to a first flap (26) which is detachably connected to a second flap (20) attached to the first tube member (14).

  • Patent number: 4660677
    Abstract: Personnel evacuation apparatus for use with an offshore platform. A launching ramp that is mounted to the platform by a gimbal is stowed in a vertical position with a survival vessel secured in the entry end of the ramp. A release mechanism activatable from the deck of the platform enables flotation members secured to the exit end of the ramp, to pivot the ramp about the gimbal to its deployed position. The gimbal further permits the ramp to maintain a usable orientation in spite of inclination of the deck of the platform by due to pitch, roll or yaw. The exit end will pivot under wave action so as to gravity launch the survival vessel downwind and, upon release of the boat securement, carry the vessel safely away from the platform.
