The three-hulled oil combatting vessel (500) according to the invention has a separating structure (100), which pushes ice blocks (J1 ), which move between the middle hull (SH1 ) and the side hulls (SH2, SH3) from the prow to the stern, underneath the water surface (WL1 ). Said structure (100) may for example be a grate in the longitudinal direction of the vessel (500). The density of the oil (B4) or oil refining product to be collected is smaller than that of the water, so the oil (B3), which has been separated from the ice blocks (J1 ) that were pushed down, tends to rise through the separating structure (100) to the water surface. The separating structure (100) thus separates the oil (B3) from the ice blocks (J1 ), whereby the collecting of the oil for example into a container is made significantly easier. The separated (B4) oil can thus be collected from the relatively ice-free water surface (WL1 ) with an oil collecting device (200), which may have for example a brush skimmer. |
