DECEMBER 18, 2014 – The Meyer Werft Germany, Meyer Turku, STX France, and Fincantieri shipyards have placed orders with Wärtsilä for the supply of fresh water generators to a total of seven cruise ships.

The orders were placed by the shipbuilders between September and November 2014. Delivery of the Wärtsilä systems is scheduled to commence in May 2015 and will be completed by autumn 2017.

In all, Wärtsilä will deliver ten large MSF distillation systems with unit capacities spanning from 115 tons/day to 900 tons/day, and four Single Stage Desalination systems (SSD) with unit capacities of 30 tons/day.

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 that need high quality water. The evaporators, which employ the multi stage flash (MSF) principle, utilize the waste heat from the ship's main engines to evaporate seawater in multiple stages under vacuum. Every consecutive stage has a slightly lower pressure, which leads to high energy efficiency.

The MSF evaporator produces fresh water with consistent high quality and reliability as the process is independent of changing seawater temperatures, and very tolerant of impurities (e.g. algae) in the seawater. The extremely low salt content remaining in the end product (less than 5ppm) makes it suitable for even the most demanding technical applications.

"Major cruise ship owners are already using Wärtsilä Serck Como evaporators on their vessels and are clearly satisfied with the reliability and quality of the fresh water produced by our solutions," says Mr. Vesa-Pekka Virkki, Managing Director, Wärtsilä Serck Como. "This is evidenced by the fact that more than 130 cruise ships in global operation have our evaporators on board. We are very proud to continue to support these leading cruise companies with systems that feature numerous benefits, including improved energy efficiency, flexible design and easy maintenance."
