The technology group Wärtsilä has successfully installed its Serck Como Horizontal Tube Evaporator fresh water production system onboard the pipe-laying vessel, ‘Lorelay’, owned by offshore contractor Allseas. This is the first commercial installation of this Wärtsilä innovation. The retrofit project produces clean water for technical applications and human consumption, and has led to fuel savings of as much as one ton per day. The unique aspect of the Wärtsilä HiTE is that it is a multi-stage evaporator specifically designed for small to medium capacities of 30 to 150 tonne per day. Previously, significant design compromises were needed in order to handle such capacities. The Wärtsilä HiTE is designed to function in a wide range of operational areas, that is shallow waters with poor quality seawater, where alternative technologies, such as reverse osmosis or plate technology, reach their limits. The operation of the Wärtsilä HiTE achieves energy savings of 75 percent compared to single stage designs with a specific heat consumption of 200 – 280 kWh per tonne, depending on design.

Taco Straathof, Technical Inspector, Allseas, said that “This evaporator produces pure distillate, even in difficult seawater conditions, plus it does so reliably and with low operating costs. The possibility to operate the unit at part load gives it great flexibility to utilise available waste heat. Our engineering team has confirmed that the Wärtsilä HiTE is exceeding our expectations, and that it is completely in line with the technical specifications and the requested maximum allowed energy consumption. The system produces good quality water, and we are extremely happy with the outcome.”
