DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an arrangement for picking up objects or oil from the sea, comprising 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.
On picking up people from the sea it is customary to employ a basket which is suspended from a line, which is fastened to a derrick on board a ship. In heavy seas the basket will move quite independently of the ship, and it becomes difficult to achieve a satisfactory control of the basket. This renders difficult the picking up of a person who lies in the sea, and it can also be dangerous for the persons involved, who can be hit by the basket and thereby be injured.
From Norwegian Patent Specification No. 140,530 there is known an arrangement in which the basket is fastened to wires both above and below, and the possibility for control of the basket is thereby greater than in the afore-described solution. But the arrangement, which is especially designed for putting out/picking up of lifeboats and other lesser boats, is rather extensive and complicated and thereby expensive and is therefore less suitable for picking up of smaller objects, such as people.
It is known to collect oil from the surface of the ocean with the aid of so-called skimmers after the oil is surrounded by a boom, which is pulled at each end by a tug boat. In that connection there is a problem that the ship in which the skimmers are present on board must be manoeuvred along the boom and thereby drives away the oil with its slip stream.
There is thus a need for an arrangement which on picking up objects is simple to control and which is of relatively simple construction and relatively reasonable. There is also a need for an effective arrangement for collecting up oil flakes.
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 substantially 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.
The invention will be further explained in the following description with reference to the accompanying drawings, where:
FIGS. 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 arrangement.
FIGS. 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. There can be arranged one or two baskets on board a ship, depending upon what one finds appropriate in the individual
