1 2 9 fresh water and the restricted capacity of holding tanks, while the second is hampered by the need to use more fuel during the salt-water conversion process, which increases costs and emissions. Operators must also consider the logistics and impact of storing and disposing of wastewater. A cruise ship carrying 2,000 passengers and 600 crew members can use over 63,000 litres of water per day, just to flush toilets. Sanitary product provider Waterless Co believes a simple solution to this problem is to use less water, particularly via urinals. “Waterless Co urinals are the best as they do not use any water, saving vessels approximately 155,000 litres of water per urinal, per year,” says Klaus Reichardt, founder and CEO at Waterless Co. “These urinals also require less maintenance and are more hygienic because there is no water where bacteria can grow.” As water becomes an increasingly precious commodity and marine ecosystems continue to decline, ship operators must also find new methods for managing ballast water. Often, seawater is taken on while in one port, stored in the bottom of the ship to act as a stabiliser, and then discharged in another port. As a result, ballast water can transfer organisms and bacteria between marine habitats, which can have detrimental effects on the ecosystem. Organisations worldwide are working to address these issues. For example, Francebased BIO-SEA by BIO-UV Group has developed a solution to prevent this by using a combination of mechanical filtration and ultraviolet disinfection. British firm Chelsea Technologies also supplies environmental compliance monitoring systems including ballast water testing and exhaust wash water monitoring systems. Its Sea Sentry scrubber wash water monitoring system measures the water inlet and outlet of wet exhaust gas scrubber systems, enabling cruise and ferry operators to meet stringent environmental regulations.
