Definitions

• This invention relates to an oil removal apparatus which is characterized of the fact that it comprises a boat and one to the boat detachably attached oil removal cassette.
• the cassette is intended to remove oil from harbours and open sea during the propulsion of the boat.
• the intention is also that the cassette shall be easily transportable, for instance by a helicopter, to different scenes of accident, where the cassette shall be easily attachable to the fore part or any other part of the boat if that is desirable.
• the stern part of the oil cassette is provided with attachment means which are intended to be fastened to the sea-going boat.
• Fig. 1 is a side view of a boat with one to the stem of the boat attached oil removal cassette according to a possible embodiment of the invention
• Fig. 2 is a plan view of the apparatus according to Fig. 1.
• the oil removal cassette 11 comprises a buoyant body made of two parallel pontoons 12 and therebetween centrally disposed band conveyors 13,14 for oil collection from the water surface.
• the boat 10 is intended to be driven by propellers 15 through the oilcovered water with the bands of the conveyors 13, 14 in movement.
• the conveyors 13 ' 14 can be arranged in different ways in relation to the pontoons 12.
• the foremost positioned conveyors 13 in relation to the direction of motion of the boat have been obliquely oriented in relation to the horizontal plane of the cassette.
• the bands of the conveyors 13 have been perforated for collection of thick oil spills, while the conveyor 14 positioned at the stern of the cassette is oriented perpendicularly to the cassette for collection of thin oil.
• a container 16 is arranged for collecting removed oil. It is, however, to be understood that also means formed in another way can be arranged on the cassette 11 for the oil collection.
• the oil removal cassette 11 is detachably attached to the boat 10, preferably to its fore end.
• the stern part of the cassette is provided with attachment means, which in the shown embodiment comprises a number of separated plates 17 or similar extending astern which plates are joined by means of a transverse cylindrical bar 18.
• the fore end of the boat is provided with a fork 19, the prongs 20 of which are oriented straightly upwards and are so positioned that they are inserted between the plates 17 of the cassette 11 when connecting the cassette 11 to the boat 10.
• the stern parts of the pontoons 12 have been rearwardly narrowed. Due to this mentioned performance that advantage is attained that the cassette 11 can follow the movement of the water independently of the pattern of movement of the boat, so that the conveyors positioned on the cassette always collect oil from the surface layer of the water, where the concentration of pollutions and oil is large.
• the boat at the fore end part can be provided with a superstructure 21 inside which the cassette 11 can be received as has been shown by broken lines in Fig. 1.
• the oil removal cassette (11) can be fastened to the stern part or the bow part of the boat (10).
• the bow part of the cassette is provided with outwardly extending plates which are joined by a bar. This bar is connected to forks in the same way as has been shown in the drawings, which forks are fastened to the bow part of the boat. It ought to be observed that the attachment means of the boat 10 can change places with the attachment means of the cassette 11 without leaving the basic idea of the invention.
