It has been discovered that a mechanical flotation system 10 having only two cells 18, 20 can be nearly as efficient as one having more cells, yet provide an apparatus with a considerably smaller footprint. significantly reduced capital and operating costs, as well as be resistant to floating oil recovery platform wave effects The dual-cell mechanical floatation system 10 has, in sequential order, an inlet chamber 16 and two gasification chambers or cells 18, 20, each with at least one gas ingestion and mixing mechanism 32, and a discharge chamber 24. A common primary skin collection channel 40 atop the partition 44 dividing the gasification chambers 18, 20 efficiently channels away the bulk of the floating collected matter At least one baffle 60 depending from the top of the vessel 12 near the primary skin collection channel 40 helps dampen the action of the fluid containing the suspended matter when the vessel 12 is affected by wave motion against the floating oil production platform. The liquid or froth levels 50, 66, and 76 can be intermittently raised for collection or otherwise lowered during periods of excessive turbulence (e.g. pitch or roll) to prevent clarified liquid from being collected with suspended matter.
