The Meyer Werft Germany, Meyer Turku, STX France, and Fincantieri shipyards have all placed orders with Wärtsilä for the supply of fresh water generators to a total of seven cruise ships.
The orders were placed between September and November 2014. Delivery of the Wärtsilä systems is scheduled to commence in May 2015 and will be completed by autumn 2017.
Wärtsilä’s delivery comprises a total of 10 large MSF distillation systems with unit capacities spanning from 115 tons/day to 900tons/day, and 4 Single Stage Desalination systems (SSD) with unit capacities of 30 tons/day.
The Wärtsilä Serck Como fresh water generators produce the fresh water needed onboard a cruise ship for deck washing, laundry, cabins, swimming pools, and technical applications.
The evaporators, which employ the multi stage flash (MSF) principle, utilize the waste heat from the ship’s main engine in order to evaporate seawater in multiple stages under vacuum. Every consecutive stage has a slightly lower pressure.
