66 Water Water efficiency is a major concern on all passenger ships. Hapag-Lloyd Cruises intervenes at source to reduce water use: “We fit the taps on our ships with an aerator. This small nozzle is screwed onto the tap and reduces the water used by up to 70 per cent.” Virgin Voyages says “low-flow water fixtures, water-efficient dishwashers and laundry equipment (like tunnel washers and eco-friendly dry cleaning), and vacuum toilets ensure smart water use.” Discouraging water wastage by guests is another popular strategy. A-Rosa says that the latest generation of its ships “is equipped with water dispensers, and the rest of the fleet is being adapted for them. This will allow us to provide all our guests with refillable water bottles in their cabins instead of disposable plastic bottles.” HVAC Heating, Ventilation and A/C (HVAC) systems are becoming ever more efficient onboard cruise vessels. Celebrity Cruises says: “Our ships are equipped with the latest and most efficient airconditioning equipment commercially available… coupled with improvements in system design and automation.” Cunard states: “We’re improving the quality of our air emissions by installing Advanced Air Quality Systems across our fleet.” Virgin Voyages says: “Implementing optimised HVAC systems, LED lighting, and real time energy measurement ensures smart energy use throughout the ship”. Other initiatives Oceanwide Expeditions says it has designed its new vessels, Hondius and Janssonius, “from the ground up to employ only the latest green technology. The company deploys LED lighting, steam heating and biodegradable paints.” Water wins Norwegian Cruise Line is taking multiple actions to boost water efficiency and has increased onboard water production with evaporators and reverse osmosis (RO) plants that use seawater as the source, which reduces the need for the bunkering of fresh water. “This is particularly important in countries where fresh water is limited and best reserved for local populations,” says the company. “In 2020, we used approximately 2.5 million m3 of fresh water for all onboard operations, down approximately 65 per cent compared to 2019, due to the voyage suspension. 83 per cent of water used onboard in 2020 was self-produced.” CURRENT REPORTED ACT I V I T Y Source: Norwegian Cruise Line Holdings
