Positive Steps In Making Cruises Kinder To The Environment
Cruise lines have recently come under a great deal of pressure from governments to clean up their act and make cruising a more sustainable and environmentally friendly activity. Cruise ships have long been known to be one of the more ‘unclean’ modes of transport, which is an image many cruise lines are keen to move away from. Couple this with the increased taxes that vessels are now receiving based on carbon emissions, and there is real motivations to innovate. Lets take a look at 3 of the most promising eco developments.
More Efficient Ships. Old ship designs really didn’t have their environmental impact in mind, but the latest ships are built from sustainable materials and put together using eco-friendly techniques. The materials are getting lighter so less energy is needed for propulsion, soft sails are often being included, and a company in Ireland have pioneered a biogas-powered engine, set to soon be used by Cunard Cruises. Hull design has also been dramatically resigned by the same Irish ship building company, allowing the energy usually lost when the boat impacts waves to be turned into forward propulsion instead.
Hybrid Boats. A number of cars and trucks have been developed with hybrid fuel-battery engines now and have integrated very well with the more traditional vehicles. Now ship builders such as those making boats for Silversea Cruises are getting in on the action and making boats that couple the traditional diesel power with electrical power. When berthed, a ship simply plugs in to the shoreside power supply and charges its batteries, what could be easier
Cargo Sharing. A great idea being trialled by Oceania Cruises is ‘cargo sharing’. If a cruise ship has not filled all its spaces, it can offer to carry commercial cargo for other companies sending things to the same place, for a small commission of course. The cruise company wins as they get money they would otherwise not have got, the cargo company does not have to charter its own boat, and energy is saved that reduces carbon emissions.
