In the latest ‘eco-friendly’ move by governments to reduce carbon emissions from various modes of transport, the cruising industry has been put under the microscope and asked to invest in more sustainable and cleaner ship developments in the coming years. A number of damming environmental reports that showed cruising to be one of the most eco unfriendly forms of transport helped many cruise companies to reassess their operations. Additionally, there is added incentive from the fact that carbon emissions above a certain level are soon to be heavily taxed, which of course no cruise company will like. Below are details of three great innovations in making cruise ships more eco-friendly.
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 a ship comes into harbor it is connected to the shoreside power source and gets a quick charge up of its huge batteries
Cargo Sharing. A great idea being trialled by Oceania Cruises is ‘cargo sharing’. When a cruise ship has spare room onboard, they effectively rent it out to companies wishing to transport cargo to the destination on the ships path. A few extra bucks are earned by the cruise companies who would have otherwise wasted space, the company who are shipping the cargo massively save on costs and less pollution is released into the environment. Everyone’s a winner.
