Distillate and Fresh water stored in the ship's tanks are everyday basic needs for passengers, seafarers and machinery. A high level of comfort must be guaranteed, considering up to 200 litres per day of fresh water each during long trip periods and thousands of persons aboard. All machinery recirculating cooling circuits must be readily refilled in case of maintenance or breakdown to keep their safe and reliable operation under control. That's why, for the technical operator, fresh and distillate water generation deserve a place in primary daily duties.

This course provides skills regarding running, stopping and management techniques on all the main systems and plants used onboard to produce distillate and fresh water from seawater on ships. Those types of machinery may be found in different configurations due to the ship's needs and standards requested by the owner to the makers. Relevant physical and chemical considerations are intended as basic principles on which each machinery works. Engineers in charge of freshwater generators must be familiar with operating fundamentals for the safe and reliable operation of the systems.
