Dual-Fuel LNG Ships For Costa Group – Other Recent LNG Installations – Converting Cruise Ships to LNG

The Cruise Examiner for 3rd August 2015

Costa LNG

In many ways, Costa’s new pair of 180,000-tonners will resemble AidaPrima, now being completed in Japan

Last week’s big news was that Meyer Werft is to build two new next-generation cruise ships for Costa Cruises, which will be the world’s first, and most certainly the largest, to run on LNG. While these will be built at its Turku shipyard, two similar ships will be built at Papenburg for sister company Aida Cruises. By burning LNG, large passenger ships are able to reduce their CO2 emissions by 25%, Nitrogen Oxides by 85 to 90% and Sulphur Oxides to practically nothing. LNG is a clean fuel, producing very low particle emissions, no visible smoke and no sludge. And as a bonus it is cheaper than marine diesel oil. There are problems however. LNG’s volume is 1.8 times that of diesel fuel, and with the necessity of using highly-insulated cylindrical tanks, the space required for bunker storage is almost four times what is required for conventional square tanks.
