Cruise Lines International Association (CLIA) says cruise lines are transforming the modern fleet with new technologies and designs to protect the oceans, air and destinations that millions of cruise passengers enjoy each year. Each year the association showcases cruise lines’ technologies that sustainably reduce the industry’s environmental footprint.
“The cruise industry recognizes the importance of investing in innovative ship technology to preserve our environment and provide an eco-friendly travel experience,” said Cindy D’Aoust, president and CEO, CLIA. “And, with each new build, CLIA Cruise Line Members raise the bar for developing environmentally friendly ships.”
CLIA’s Environment Sustainability Report 2016 says its members have committed more than $8 billion to build new liquefied natural gas (LNG)-fueled cruise ships. These next-generation ships are expected to use LNG to generate 100 percent of the ship’s power in port as well as on the open seas, which will significantly reduce exhaust emissions to help protect the environment.
LNG – the Marine Fuel Alternative
CLIA Cruise Line Members are investing $1 billion in environmental technology, including technologies for use of Liquefied Natural Gas (LNG) as an alternative fuel. Cruise lines are launching ships powered by liquefied natural gas (LNG), eliminating soot particles and sulfur oxides, to reduce fuel consumption and CO2 emissions. For newly launched vessels, new dual-fuel engines allow for the efficient and effective use of multiple fuels, such as LNG and traditional fuel oils.
Innovations in tank design and placement has also allowed for safe storage of LNG onboard.
To date, seven cruise lines have announced plans to build up to 16 LNG-propelled cruise ships, with the first one expected in service in 2019.
Other technologies pioneered by the cruise industry related to air emissions reduction, advanced wastewater treatment systems, solar panels, and heating, ventilation and air conditioning systems.
CLIA 2017 Environmental Practices Report
According to Final Report: Evaluation of Cruise Industry Global Environmental Practices and Performance prepared for CLIA by Energy and Environmental Research Associates, LLC (published January 2017): when comparing cruise fleets with other maritime vessel types, CLIA members are leaders in adopting cleaner fuels, controlling air emissions, and preparing vessels to connect to advanced shore-based energy systems. One of those fields is fleet adoption of cleaner fuels and advanced engine technology.
The report finds:
“LNG has emerged as a low-cost, low-emissions alternative to conventional marine bunker fuels. Retrofit and initial capital expenditures can be significant, but operators have the potential to recover high CAPEX costs through low fuel costs, while also exceeding MARPOL Annex VI regulations.
“The significant investments made by the cruise industry to utilize a cleaner and more cost effective marine fuel adds to the many commercial ships which are already using LNG; the logical expectation is that the necessary infrastructure will follow to overcome challenges with storage, transportation and CAPEX costs.
