Abstract

The present invention relates to a skimmer for collecting a substance, such as crude oil, from a liquid surface and a method for removing a substance from a liquid surface. The skimmer comprises: − a buffer vessel provided with an open top end and configured for at least temporarily holding a mixture; − a floatation element that is arranged on or at the buffer vessel to float on the liquid surface; and, − at least one pump provided with at least one drainage connection configured to be connected with a drainage conduit; wherein the buffer vessel comprises an outer edge that defines an inlet opening for accepting the mixture of the substance to be removed and the liquid, wherein the at least one pump is configured for pumping the mixture from the buffer vessel through the drainage conduit to a drainage designation, and wherein the skimmer further comprises a mixture inspection element.

Abstract

The invention relates to an apparatus for collecting a lighter fraction floatable liquid from a heavier fraction liquid, such as a lighter fraction floating oil from a heavier fraction water, the apparatus comprising: a floatable collecting container and a cover placed above the collecting container leaving a continuous passage slot free; wherein the opening of the passage slot is adjustable by an inlet adjustment ring. The invention also provides a method to operate such an apparatus.
