Apparatus in fluid communication with a water leg portion of an offshore drilling or production platform sump tank for conveying the separated water into contact with an organophilic clay such that the hydrocarbons and other organic materials commingled with the sump tank water will be adsorbed onto the organophilic clay and the water will pass through the clay and will be conveyed back to the ocean water without contamination.

[ What is claimed is:] [6.] A method of separating water from a combination of water and oil on an offshore oil well platform disposed above an ocean, so that the oil is not returned to the ocean comprising:collecting the oil and water in a settling vessel on said platform and allowing the oil and water to settle to form a lower water layer and an upper oil layer, said lower water layer including an oil contaminant;draining a portion of the water layer from said settling vessel;treating said drained portion of the water layer by flowing said drained portion of said water layer into a vessel containing an organophilic clay for intimate contact of said drained water with said organophilic clay and adsorption of said oil contaminant on said organophilic clay said vessel disposed within 10 feet of an ocean water level; andflowing the treated water out of said organophilic clay-containing vessel and into the ocean.
