Effluent oil collecting vessel

摘要

An improved oil collecting vessel of the twin-hull type is described here. An oily water suction means is provided with a float that supported by a linkage mechanism which in turn is fixedly secured to an upper deck of the vessel. The oily water suction means may therefore be raised or lowered without changing its direction so as to follow the wave motion of the water surface region delimited at its opposite side edges by the hulls. Oily water floating on the water surface region is sucked through the oily water suction means and is conveyed to a tank in the vessel through a suction pipe. The suction of the oily water is enhanced by an ejector provided in the midway of the suction pipe. An effluent oil converging section is provided in a reentrant form in front of the oily water suction means and is delimited by guide plates on its opposite sides. In front of the oily water suction means is a jet water injection port. In order to prevent a gap space from being formed between the hulls and the oily water suction means in front of the oily water suction port, rubber guides are fixedly secured to the hulls in the proximity of the water line.
