5 Fuel Consumption/Emissions

6 Total Energy Optimisation: Demand, Production & Operation

7 Efficient and Environmentally Friendly Cruise Ships Low Energy Demand Energy efficiency driven concept design Volume reduction Weight optimisation Reduced heat emissions High efficiency equipment Optimised capacities Low hull and appendage friction Efficient propulsion Efficient Operation Training Best practises Reduction of speed Route planning Trim control Wind and wave observance Optimised tank volume Presence monitoring Shore-side utilisation Recycling Energy Production Efficient machinery Optimised machinery Waste heat recovery Emission reduction LNG and bio fuels Fuel Cells Wind energy Solar power February 15, 2011 Slide 7

9 New Energy Efficient Cruise Ship Concepts By reducing the energy requirements together with improved waste heat recovery and optimized total energy flow, 20% to 40% better energy efficiency is achievable compared to large cruise ships delivered only 5 years ago Energy Requirement Hotel A/C compressors Auxiliaries Propulsion Delivery 2008 New Concept

10 EEDI - Energy Efficiency Design Index for New Ships EEDI is currently under development by IMO Marine Environment Protection Committee Coverage in first phase: oil and gas tankers, bulk carriers, general cargo and container ships, ro-ro carriers and passenger ships EEDI value represents the production of CO2 in relation to the benefit for the society For the moment EEDI is voluntary design criteria Preliminary limiting curves presented here are calculated from the data of 71 modern cruise vessels built EEDI 25 EEDI Limit Curve EEDI Limit Curve -12.5% EEDI Limit Curve -25% 20 Cruise Ships: STX Finland Europa Elation Fantasy Costa Atlantica Voyager of the Seas Freedom of the Seas Oasis of the Seas Gross Tonnage 07 December 2011 Page 10

13 LNG Natural gas has become a popular fuel option for shipowners trying to meet legislative emissions requirements as well as to gain benefit from emission based route and port fees. Pros and cons: ++ emissions -- bunkering + gas reserves - storage - methane slip - spillage - combustion process

14 Fuel System - Storage Tanks Location of the storage tanks - in the bilge or in the aft end? Grounding vs collision - which is more probable? Provision & preparation Rule risks Size of the ship vs weight of the fuel / bunkering frequency ( trimming ) Volume of the tanks / type of tanks Vacuum insulated type C tanks, 2 pcs Gross volume 2 x 200m 3 ~ 160 tonnes LNG Safety precautions Gas relief mast Water spray cooling for protection LNG gasification in cold box using ME LT-heat Heat from AC-system, cold recovery
