Definitions

  • the present invention relates to a device for the establishment and / or removing a steerable propulsion pod from a ship with two so-called adjustable propulsion pods each comprising a nacelle suspended from the ship by a sail.
  • the invention thus relates to such a device, characterized in that it includes a cradle for receiving the moving pod, located between two arms a buoyant beam, one end of each arm being rigidly linked said cradle, the other end of a first arm comprising means for link, articulated around a horizontal axis, with the veil of the other pod in place on the ship, the other end of the second arm comprising means for connection, articulated around a horizontal axis and a vertical axis, to a building floating annex.
  • Fig. 1 thus shows the rear part of a ship 1 equipped with two pods steerable propulsion 2 and 3, each pod comprising a nacelle 4 suspended from the ship by a sail 5 acting as a control surface.
  • Fig. 2 shows a device according to the invention for the establishment and / or the removal of a pod on a ship fitted with a second pod in place.
  • the device comprises a cradle 6 for receiving the pod to be deposited, or to be placed, fixed between two arms 7A and 7B of a buoyant beam 7.
  • This beam is for example a hollow and partitioned metal beam.
  • the first arm 7A of the beam 7 is rigidly linked by one of its ends to the cradle 6, while its other end has a fork 8 for its connection, articulated around a horizontal axis 9, to the web 5 a pod in place on the ship 1: the pod in place on the ship, as first support point of the beam 7 (7A, 7B) for removing or placing place of the other pod.
  • this involves removing the pod 2 and it is therefore the pod 3 which is used as the first fulcrum of the beam 7, as shown in fig. 4 to 7.
  • the second arm 7B of the beam 7 has a first end rigidly linked to the cradle 6 while its other end includes means for link articulated along two axes perpendicular to a floating building annex 10.
  • Fig. 3 shows more particularly an example of this connection articulated: it includes a vertical pivot 11 linked to an articulation axis horizontal 12 swiveling at the free end of the arm 7B, while the pivot 11 is intended to be introduced into a vertical circular orifice 13 of a pivot support 14 linked to the floating building annex 10.
  • This annex building 10 can be any type of floating building: box metal, barge, service vessel, floating crane, etc.
  • This building annex is ballastable or the pivot support 14 is fixed to the building with means for adjusting its vertical position.
  • Reinforcement arms 15 to 18 stiffen the assembly, connecting the cradle 6 to beam 7.
  • the spacing of the upper end of the U-shaped cradle 6 is held by arms 19 and 20 which are articulated so that they can be opened from so as to allow the extraction of the pod from its cradle by a means of lifting, or lowering it into the cradle during a setting operation place of the pod, as shown in fig. 7.
  • Means of securing, not shown, pod on the cradle are provided.
  • Figs. 4 to 7 show the different steps for removing the pod 2.
  • the pod 3 remaining in place is oriented in its normal position, the propeller 21 located in front of the nacelle 4.
  • the level and heel of ship 1 are adjusted by ballasting so as to allow the veil 5 to be straddled by the fork 8 of the arm 7A and its fixing by the horizontal articulation axis 9.
  • the assembly is then rotated 90 ° (fig. 5), using the motors of orientation of pod 3 and possibly the motors associated with the building annex 10.
  • the building 10 is sufficiently ballasted, or the support 14 sufficiently lowered, so that the pod 2 to be dropped can be inserted in the cradle 6 without contact.
  • the building 10 is then deballasted, or the support 14 raised, so as to that the cradle makes contact with the pod 2 to be dismantled.
  • the pod 2 is stowed in the cradle 6 then the lifting effort is increased so as to exert on the pod 2 an upward effort slightly less than the weight of the pod.
  • the beam 7 constitutes a lever making it possible to distribute the weight to be supported on the pod 3 remaining in place and on the building annex 10 in a proportion equal to the inverse of the length ratio arms 7A and 7B.
  • the pod 2 to be deposited is then uncoupled from the vessel by the means of support of the pod internal to the ship, then the support 14 is lowered, or else the annex building 10 ballasted, and we release the cradle 6, responsible for pod 2, from below the vessel by a new rotation of 90 ° in opposite direction from the beam 7, by means of the pod orientation means 3 and possibly engine power in annex 10 (fig. 6).
  • the arms 19, 20 are open and it is possible, using a means of lifting 22 (fig. 7), remove the pod 2.
  • the device of the invention is simple as well as its procedure use.
