Water supply for offshore installations

Like offshore installations such as oil rigs or fish farming, ocean-going navy vessels are accustomed to produce fresh water from seawater. The vessels cannot rely on storage tanks but require freshwater production to be available 24/7.


For a retrofit on several vessels in a specific class, the requirement was to supply more water with the same power supply while keeping within the space available. In this case, the WM4800E watermaker proved to be a great match. This desalination unit produces 67% more water and expends less than 50% of the energy. In addition, the planned maintenance has been significantly reduced in comparison to the previous desalination unit with a plunger pump.


Thanks to AqSep reverse osmosis technology, the crew now has plenty of fresh water and they no longer have to worry about maintenance efforts. This is due to the fact that the desalination unit operates fully automatically and will adapt to changes in seawater salinity and temperature.
