In a offshore oil and gas platform located over seawater in an open sea environment, the platform having drilling equipment, crew quarters, and a potable water holding tank for holding potable water, a portable desalination apparatus for producing potable water from seawater. The apparatus is comprised of a support skid to which is mounted a plurality of removable lifting lugs. A pump with associated piping and valves are fixed to the skid for collecting seawater from the open sea environment. Additional piping and valves are provided for moving seawater from the pump to a seawater filter. Additional piping and valves are used for moving the filtered seawater to a plurality of first pressure vessels each having reverse osmosis elements to produce a first quantity of brine water and a first quantity of desalinated water from the filtered seawater. Other piping and valves are used to move the first quantity of brine water to a second plurality of pressure vessels, each of the second pressure vessels also has reverse osmosis elements to produce a second quantity of brine water and a second quantity of desalinated water. Additional piping and valves are used for discharging the second quantity of brine water to a disposal system and collecting and transporting the first and second quantities of desalinated water an ultraviolet light chamber to expose the desalinated water to ultraviolet light to produce potable water. Structure is provided for discharging the potable water to the potable water holding tank of the platform.
