Abstract
An oil-spill-combatting water craft is provided with at least one protruding boom but most suitably one on each side of the craft, the booms directing surface water and oil present in it into a conduit inside the craft, the inlet and the outlet of the conduit being located in the side of the craft. The purpose is to provide a simple, high-capacity arrangement in which the flow is, nevertheless, relatively calm also when the sea is rough. With this in mind, the conduit has been implemented as a circulation conduit the outlet of which is situated towards the bow from the inlet and in which the water flows automatically owing to the water-raising and water-guiding effect of the boom. The separating means for water and oil, fitted inside the conduit, is a rotating arrangement which allows water to flow through and is, for example, made up of rows of bristles. In front of the outlet of the conduit there is fitted a baffle which extends obliquely outwards and backwards.
