Abstract
An arrangement on a water craft for collecting oil that is present on the surface of the water, particularly among ice blocks. The underside (1A) of the craft's bow (1) has been made substantially planar and very gently inclined, for instance about 10.degree.-20.degree., so that when the craft is travelling forward the ice blocks (2) might be forced along the underside (1A) under the water and be simultaneously flushed in the water. Moreover, in said underside (1A) have been made water inlet openings, which are elongated, parallel slits (3) and which prevent the entry of ice blocks. Inside the craft, the oil (5) is separated from the water (4) by means of a separating member (6), whereafter the water (7) is pumped out again. To intensify the flushing of the ice blocks (2), the pumped-out water is jetted against the ice blocks in the region of the inlet openings (3). The bottom of the bow (1) may be slightly deeper on the sides than its planar centerpart.
