EdmPair Posted April 3, 2014 #1 Share Posted April 3, 2014 I have been on the Grand Princess and was just now reading a thread on Alaska where it was suggested people take the Coral Princess or the Island Princess. Wanting to know how they all compare, I dug up photos. Well, frankly, it looks like those two ships have warp engines at the top of the stacks. Tell me this is TRUE! ;-) M Link to comment Share on other sites More sharing options...
Pam in CA Posted April 3, 2014 #2 Share Posted April 3, 2014 (edited) ROFL! They are decoration. No purpose. :) They signify that the ship has a gas turbine engine. Four Princess ships have them: Coral, Island, Sapphire and Diamond. I was on the Coral four years ago when we were asked to join a search for some lost fisherman. The search area was about 50 miles away from where we were. The engines were put on full power and the gas turbine engine used as well. It really did feel as though we were flying! I went out on Aloha deck forward and could barely open the door. Once open, I was blown against the bulkhead. Sadly, even after searching for hours, the fishermen were never found. I saw some debris from their boat. :( The gas turbine engine is used only in an emergency or when speed is required since it is far more expensive to operate.

EdmPair Posted April 3, 2014 Author #3 Share Posted April 3, 2014 I was afraid of that but also thinking the 'cigars' were of some function or other. I am also glad you saw the humour in it. Thanks for all your insights and information over the years here on CC. M Link to comment Share on other sites More sharing options...
Whoop98 Posted April 3, 2014 #4 Share Posted April 3, 2014 We sail on the Island in August. I have been planning this since November, not once did I see the warp engines :). So I just looked, and sure enough, they really do like like that and I will never miss them again. Thanks for explaining what they do Pam in CA!

dmwnc1959 Posted April 3, 2014 #5 Share Posted April 3, 2014 On some of the ships that have those they seem to be capped on the front. I saw the Coral Princess a couple of years ago in Fort Lauderdale and took these pictures: Link to comment Share on other sites More sharing options...

I saw the Coral Princess a couple of years ago in Fort Lauderdale and took these pictures: Yes, they are completely faux on the Sapphire and Diamond Princess. I was told by an officer on Coral Princess that they do channel air down to the turbine which is located in the funnel. Here's the Sapphire's...

Rare cr8tiv1 Posted April 3, 2014 #8 Share Posted April 3, 2014 Outstanding photography. Thank you very much. She will be my home for 18 days. Really looking forward to being on my favorite ship again. I will have to look at her engines with a different perspective. Link to comment Share on other sites More sharing options...

beach_fever_4ever Posted April 3, 2014 #10 Share Posted April 3, 2014 My understanding was that the gas turbines are used in ecological sensitive areas such as Alaska as they do not produce soot as diesel fuel does. Link to comment Share on other sites More sharing options...
eldridchapman Posted April 3, 2014 #11 Share Posted April 3, 2014 (edited) Well, if you want to be specific it's actually the General Electric LM2500+ gas turbine. It's used by the US navy :D http://www.geaviation.com/engines/marine/lm2500plus.html Edited April 3, 2014 by eldridchapman Link to comment Share on other sites More sharing options...
chengkp75 Posted April 3, 2014 #12 Share Posted April 3, 2014 My understanding was that the gas turbines are used in ecological sensitive areas such as Alaska as they do not produce soot as diesel fuel does. That was the case when these ships were built, and you only had to meet stricter emissions requirements while in port. Since California started their CARB zone a few years back requiring lower sulfur emissions out to 40 miles, and now with the US ECA, which limits sulfur out to 200 miles along the US and Canadian coastline (including Hawaii, Puerto Rico and the USVI), the gas turbines are less viable from a financial standpoint. Particularly when the US ECA restricts sulfur emissions further in 2015 to only allow use of 0.1% sulfur fuel (restricting use to either costly diesel fuel, or installing scrubbers at $1-1.5 million per engine (not per ship)). The problem with the gas turbine engines is that they are much less fuel efficient, and burn a costlier fuel than the diesels. Link to comment Share on other sites More sharing options...

Thats why they shut er down and plug her in some ports. ;) Edited April 3, 2014 by Colo Cruiser Link to comment Share on other sites More sharing options...

The post that you quoted mentioned areas besides port (specifically Alaska). Princess still tells passengers that the gas turbine powerplant is used when scenic cruising in glacier areas, and I do think the typical vibrations of the big diesels diminish or go away during those times.

Pam in CA Posted April 3, 2014 #16 Share Posted April 3, 2014 Yes, they are completely faux on the Sapphire and Diamond Princess. I was told by an officer on Coral Princess that they do channel air down to the turbine which is located in the funnel.If you look at your 3rd photo down, you can see that the Sea Witch "funnel" is really open and louvered to allow and direct air flow. The gas turbine is in the middle and below the deck which runs along the outside, where you see the solid wall underneath the vents. I've got a photo somewhere that I never scanned which would explain it better. :( If the faux structures were used to direct air, I think they are too high and don't see how they could direct air down through those louvers. When open, perhaps they direct the exhaust which would make more sense to me. Link to comment Share on other sites More sharing options...

Yes, and there were some photos published by Princess when the Coral/Island came out showing the soundproof room that the turbine is housed in almost eliminating the vibration/noise issues.

EdmPair Posted April 4, 2014 Author #18 Share Posted April 4, 2014 Well, this took off and took a turn. Oh well. If not warp engines, I am glad they are engine related if only as symbol. If science suddenly invent a warp engine, I will instantly write a letter to Princess to 'make it so.' Link to comment Share on other sites More sharing options...

TwoBadKnees Posted April 4, 2014 #20 Share Posted April 4, 2014 They're actually large suction devices which are activated every hour. Every lightweight item left unattended on loungers near the pools are sucked off in an effort to defeat chair hogs. Link to comment Share on other sites More sharing options...

Teris50 Posted April 4, 2014 #23 Share Posted April 4, 2014 Just left the Island Princess on April 1 after a 15 day Panama Canal Cruise and I wondered what those airplane engines were also! We had a great time, the ship was wonderful, so so about the dining room foor. Sabatini's was WONDERFULLY delicious. Did not try the crab shack or the Cajun option so can't say if they were worth the extra expense. Had a mini suite and we spent almost all afternoons on the balcony reading, playing cards or napping! Hung our posters when going through the canal, and the weather was perfect, calm seas, except for the night we traveled to Aruba! Link to comment Share on other sites More sharing options...
Eagle_and_hawk Posted April 5, 2014 #24 Share Posted April 5, 2014 They are huge whale whistles. Like those deer whistles you put on the front bumper of your car to keep deer from running out in front of you, except this keeps the whales out of the way :) 1 Link to comment Share on other sites More sharing options...
