AIDAcara cruise ship

Increased freshwater production

AIDA Cruises commissioned Evac to conduct the retrofit of a modern freshwater generation system on AIDAcara, the first cruise ship of the AIDA fleet. AIDA Cruises replaced the vessel’s reverse osmosis freshwater generation system with a modern, custom-built Evac eC600 evaporator system, increasing its freshwater production capacity in the process.

Thanks to the new Evac system, the water quality onboard AIDAcara is always excellent and consistent. AIDA Cruises can operate its ship worldwide in all destinations without depending on water from shore.

Solution

AIDA Cruises selected an Evac eC600 system, custom-built to generate fresh water e.g. for the use in galleys, showers, swimming pools or laundries. The eC600 not only increases the capacity to 600 m3 per day in all seawater temperatures, but it delivers reliability through redundancy.

The Evac system requires a smaller footprint and less energy than the previous system, while still producing more water at a better quality. Not only is the Evac plant more efficient and reliable, but its modular design meant that no time-consuming and costly modifications to the ship’s structures were needed, and the entire retrofit could be completed at sea rather than in dry dock.

Results

Old systems use at least double the energy when compared to modern systems. Savings are even more dramatic, when a reverse osmosis system replaces an evaporator system. Modern cruise lines are after far more than just efficiency and savings. In a day and age where cruising is becoming ever more popular, sustainability is of key importance.

“AIDA Cruises is continuously taking into account new environmentally friendly technologies that can be implemented on the ships,” says Sebastian Sala, Head of Innovation and Energy Management, Carnival Maritime GmbH, and responsible for the project on AIDAcara.

“Thanks to this new Evac system, the water quality onboard AIDAcara is always excellent and consistent. AIDA Cruises can operate its ship worldwide in all destinations without depending on water from shore.”
