A method of chlorinating drinking water on a ship with a production and distribution system includes a recirculation distribution network and device for injecting a chlorine compound generating free chlorine into the network in an injection point. A regimen set point is set for free chlorine concentration at the injection point between 0.4 and 1.2 mg/l. Free chlorine concentration is monitored proximate the injection point by a first probe. Free chlorine concentration at a point furthest from the injection point is monitored by a second probe. The chlorine compound is injected into the distribution network to maintain the free chlorine concentration at the regimen set point. Regimen chlorination is performed if the second probe does not detect free chlorine concentration variations from the regimen set or detects variations in concentration relative to the regimen set point lower than a safety limit and/or duration lower than a safety time limit.

A ballast water treatment apparatus for a ship includes a water collection part for collecting sea water, a forward osmosis process unit for producing ballast water and treatment water obtained by desalinating the sea water collected through the water collection part, and a ballast water tank for storing the ballast water produced by the forward osmosis process unit. Since the sea water is treated using a forward osmosis process, fresh water required within the ship can be supplied and the treated sea water can be used as ballast water. In addition, since waste heat and carbon dioxide generated in the ship are used to treat the sea water, the ballast water can be treated and produced in a low-cost and high efficient manner.

An environmentally friendly ship propulsion system and a method for propelling a ship. The ship propulsion system comprises an osmosis chamber (1), a pressure relief unit (2) and a desalination unit, the osmosis chamber (1) comprising a high salinity region (11) and a low salinity region (12) separated from one another by an osmotic membrane (13). The pressure relief unit (2) having at least one pressure-motion converter connected to the high-salinity region (11) of the osmosis chamber (1) via high-pressure line (21). The desalination unit is suitable for producing salt or at least high-salinity water and fresh water or at least low-salinity water. A fresh water pipe connecting the desalination unit with the low salinity area (12) of the osmosis chamber (1) and a salt water supply (14) is controllably connected to the high salinity area (11) of the osmosis chamber (1).
