Carnival-owned Costa Cruises has spent €22m upgrading five of its ships, adding fuel-saving and eco-friendly features.
The Italian cruise line’s flagship, Costa Serena, is the last of five ships to be dry-docked in Fincantieri’s Palermo shipyard for the environmental improvements and routine refurbishments.
New air-conditioning regulators have been installed which will increase efficiency and save fuel.
An ecological silicone-based coating has been applied to the hull to inhibit the growth of micro-organisms, which will improve the hydrodynamic performance of the ship and reduce environmental impacts.
Other improvements include new carpeting, curtains, upholstery and other items in public areas.
Three more new ships are on order, which will bring the fleet to 17 by 2012.
