ABSTRACT:
An arrangement in a water craft is described for collecting oil present on the surface of water, especially among blocks of ice. The arrangement comprises a bow part (2) the flat lower surface (3) of which is gently sloping and equipped with inlet openings for contaminated water. When the craft is moving forwards, blocks of ice are pressed under the surface (3) and at the same time rinsed. The rinsing can be promoted by means of strong water jets. In order to achieve the optimal operating conditions in each particular case, the bow part (2) has been arranged to be a part separate from the hull (1) of the craft and capable of being raised and lowered in relation to the hull, which also enables this bow part to be coupled to an already existing craft of suitable size. The bow part comprises separating devices (9) for separating oil from the inflowing water, as well as a device for removing the cleaned water. The recovered oil is conveyed continuously from the bow part (2) to a tank located, for example, in the craft.
