MelbTone Posted November 3, 2023 #1 Share Posted November 3, 2023 Cunard has announced it will stop homeporting the Queen Elizabeth in Australia from 2026 onwards. The ship will only visit the southern hemisphere on world cruise segments. In a statement from Matt Gleaves, Commercial Vice President of North America & Australasia, he said, “We know that many guests in Australia and Japan love to sail with Cunard and Queen Elizabeth is already on her way to Australia to begin her 2023/2024 homeport season starting 27 November. “The ship will also return for her scheduled 2024/2025 season and whilst this news means that from 2026 there will be no locally based program, Australia and Asia will remain important destinations on our round-the-world voyages and we look forward to welcoming guests from these regions wherever they chose to sail with us.” The ship will instead, operate year-round from North America, spending the season sailing in and around Alaska and in the winter, in the Caribbean. .... https://cruisepassenger.com.au/news/cunard-pulls-the-pin-on-queen-elizabeths-return-to-australia/ 4 Link to comment Share on other sites More sharing options...

Cruise ships accounts for 5% of the CO2 and there is nothing they can do to reduce that. Once again, ace, you have your facts wrong. World wide TOTAL shipping (tankers, bulkers, container ships, ferries, cruise ships) amounts to 3% of total greenhouse gas production (so your number is wrong), and cruise ships account for less than 5% of total world shipping (so you are about an order of magnitude out). The rest of the global transportation system (buses, trucks, cars, trains, airplanes) account for 17% of GHG emissions, yet 80% of the world's economy moves by sea. And, finally, ships, including cruise ships are working to reduce GHG emissions, as witnessed by Viking Cruises working to install hydrogen fuel cells on all their newbuild ocean ships, and Royal Caribbean already having small scale hydrogen fuel cells on some of their ships. Not to say these projects have hurdles to overcome, and years of development for safety standards, but the change is coming. Might want to get out and read a bit before quoting figures. 10 3 Link to comment Share on other sites More sharing options...
chengkp75 Posted November 3, 2023 #7 Share Posted November 3, 2023 Further refining my numbers given above, cruise ships represent 2.6% of the world's shipping gross tonnage, and only 0.2% of the number of ships in the world. 1 Link to comment Share on other sites More sharing options...

But can these new techs generate the several GIG per day per ship though? AKA the power usage of Southampton in a day? QM2 uses to my knowledge the same amount of power that Southampton the city uses. Link to comment Share on other sites More sharing options...

AKA the power usage of Southampton in a day? QM2 uses to my knowledge the same amount of power that Southampton the city uses. While the QM2 can generate more than the city of Southampton uses, it rarely does, as that would require sailing at full power of the four diesel generators 24 hours a day, 365 days a year. While the fuel cell technology will not handle a full ship's power requirement, the Viking ships will have a 6Mw fuel cell, that will handle the hotel load easily. And, they are sizing these applications up every year. 46 minutes ago, ace2542 said: I saw these new ships. The solar sails which retract won't do squat for their power needs. I believe you are mistaking the Hurtigruten cruise/ferries with the Viking Ocean cruise ships. And, with 1500 m2 of solar panel area, that equates to 1Mw of power, enough for the hotel load on a ship this size (500 pax). And, the sails, if assuming the 1500 m2 of solar panel is on both sides of the sail, that means a sail area of 750 m2, which can produce 1.2Mw of propulsive power, even at a mild 5 knot wind, and since the relationship between wind speed and sail power is to the 4th power, a 10 knot breeze would produce nearly 5Mw of power. Do you really think the company would invest in these costly technologies if they didn't provide an actual benefit? 2 2 Link to comment Share on other sites More sharing options...

Alaska is far more likely to implement shore power for cruise ships than a total ban. And, who would shut the Caribbean down, given that the term "the Caribbean" encompasses many different nations? Would they all need to agree to ban cruise ships? Link to comment Share on other sites More sharing options...

Rare foodsvcmgr Posted November 3, 2023 #20 Share Posted November 3, 2023 No doom and gloom for me with this, I’ve been hoping for years now that Cunard would make a substantial return to the Caribbean in winter. QE2 did it extensively for many years. I sailed QM2 in 2009 and 2010 when they operated a series from NY in November and December those years. Great news! 3 Link to comment Share on other sites More sharing options...

No, you don't use shore power to "charge up" a ship, no more than the city of Southampton wants to provide shore power to "charge up" commercial ships in port. It is for in port power usage by the ship, so that the ship's generators are shut down while in port. In port pollution is the major complaint against cruise ships, not their total GHG emissions. However, many small ships that will use fuel cells, have battery banks to store the power generated by the fuel cell, and these could be charged during port operations. And, in port, even the largest cruise ship only uses 9-10Mw of power, not gigawatts. If cruise ship pollution is so important to you, surprised you haven't read up on shore power, considering that Southampton has installed shore power at the two cruise terminals, which have been used to allow ships to shut down their generators 42 times in 2022. And, yes, that power can charge the ship's batteries. 3 3 Link to comment Share on other sites More sharing options...

I used to be an energy broker so I asked the question. Something you might enjoy to look at. Google UK power generation. As of 30 minutes ago I think if I am reading it right the UK is using 34.733 GW either per minute or per second. The figure increased by 5gw in an hour or so because I checked it 10.30am and it was 29gw. Link to comment Share on other sites More sharing options...

Southampton uses several gig per day in power usage. And that is larger than all 3 of those combined? Again, facts matter. Remember, that when in port, QE will use about 8 Mw of power (simply the hotel load), or about 64Mw-h for the entire port stay. Do you think they continue to run all the engines while at the dock, just to burn up more fuel? And, how do they get rid of the excess power, since the generators will only generate (burn enough fuel) to match the usage (8Mw)? Juneau uses around 600-1000Mw-h per day. Alaska gets about 33% of its power from renewable sources. 1 Link to comment Share on other sites More sharing options...
