Definitions

• the present invention relates to an arrangement for picking up objects or oil from the sea, com ⁇ prising a basket or container which is connected to a ship and which is adapted to be conveyed between a work position partially submerged in the sea and a rest position on board the ship.
• Such an arrangement is produced according to the " present invention and is characterised in that the basket or the container is rigidly connected to a derrick which is rotatable about its axis so that the basket in the work position is movable in a vertical plane substantially parallel to the vessel side of the ship, and which is pivotable between the work position, where it projects outwards substan- tially horizontally from the side of the vessel, and the rest position.
• the derrick consists preferably of an outer, hollow boom which is rotatable about its axis, and which the basket is connected to, and an inner boom which is coaxilly mounted within the outer boom, and which at its inner end is pivotably arranged on the deck of the ship.
• the inner side of the basket must be at a certain distance from the side of the vessel so that the basket shall not strike against the side of the vessel " in heavy seas. This distance shall however be the least possible in order that the object which is to be picked up from the sea shall not have the possibility of slipping between the basket and the side of the vessel, or in order that the least possible oil can flow between the side of the vessel or the container.
• Fig. 1 - 3 show the arrangement according to the invention used for picking up people, in that
• Fig. 1 shows a side view of the arrangement in the work position.
• Fig. 2 shows a front view of the arrangement in the work position.
• Fig. 3 shows a perspective view of the arrange- ent.
• Fig. 4 - 6 show the arrangement used for collecting up oil, in that
• Fig. 4 shows a side view of the arrangement corresponding to • Fig. 1.
• Fig. 5 shows a front view of the arrangement corresponding to Fig. 2.
• Fig. 6 shows a schematic plan view of a ship equipped with the arrangement together with two tug boats which pull a boom.
• Fig. 1 shows a lifesaving basket 10 which is suspended from a boom 11, which on its side is fastened to a ship 12.
• the ship is usually a supply ship or a standby ship.
• the basket consists of a netting, for example of aluminium, or a net 13 which is stretched out over a lattice work 15 and forms the bottom and end walls of the basket.
• the basket is provided in the centre with a vertical wall 16, which has the task of stopping objects which come into the basket, either from the back or from the front.
• the basket is provided in the centre with a vertical wall 16, which has the task of stopping objects which come into the basket, either from the back or from the front.
• the boom 11 which in its turn is rotatable about its axis, so that the basket can be rotated in the a and b directions of the arrows, in a vertical plane sub ⁇ stantially parallel to the side of the vessel.
• the boom 11 is hollow, and within this boom there is coaxially mounted another boom 18 which in the work position of the basket projects horizontally away from the ship 12 and is pivotable between the work position and a rest position on the deck of the ship.
• a person 17 is taken out of the sea by means of the basket 10 in that the ship 12 is moved in the direction towards the person and the basket if necessary is turned somewhat in the a_ direction of the arrow (or the b direction of the arrow if the ship moves backwards) so that it will attain a position where one is sure that those persons involved are settled in the basket, after which the basket is turned in the b direction of the arrow until the wall 16 is lying substantially horizontal. Thereafter the basket is turned ' on board the ship 12 by swinging the boom 18 in the £ direction of the arrow in an arc of about 180 ,,. with the person lying on the wall 16 which during the whole of this swinging is substantially hori ⁇ zontal.
• the control of the basket in the a_, b and directions of the arrow is carried out from the ship.
• the rotation of the boom 11 and thereby of the basket 10 is effected for example by way of a gear system.
• the swinging of the boom 18 is effected by means of a hydraulic cylinder 19, which is arranged at the inner end of the boom 18.
• the cylinder 19 is in its turn arranged on a rotatable disc or the like on the deck of the ship, so that the arc which the boom 18 describes during the swinging can be controlled substantially arbitrarily.
• Fig. 4 and 5 illustrate as mentioned above a side view and a front view of the arrangement respectively for collecting up oil.
• the basket which is employed in the picking up of people in the sea is thereby replaced with a kind of container 10 with sealed bottom 21, side walls 22, 22b and rear wall
• the front wall 20 of the container seen in a for ⁇ ward direction on the ship, is open, at least in the
• a pump 23 which via a conduit 27 is connected to a chamber on board the ship 12. Oil or oil/water mixture which runs down towards the bottom of the con ⁇ tainer 10 is pumped on board the ship by means of the pump.
• a vertical wall 24 which is regulatable upwards and downwards. This wall 24 is adjusted so that it is present with its upper edge approximately at the level of the under side of the oil flakes, that is to say substantially at the oil/water boundary surface.
• FIG. 6 shows a plan view of the ship 12 with the booms 25, which at their other ends are connected to respective tug boats 26 which pull the booms through a desired angle or desired arc rela ⁇ tive to the ship 12, depending upon for one thing the size of the oil flake. If it is a question of collecting large quantities of oil, the oil can, after a separation from the water be pumped on board the ship 12 from the latter over to a second ship.
• the booms 25 are uncoupled from the containers 10, and these are swung in on the deck of the ship as is described above in connection with the picking up of a person in the sea.
• the present arrangement makes possible a rapid and effective collection of the oil, and it is flexible in that it can be used for several purposes *
