QM2 Vibration on Deck 13?

Recommended Posts

I've just read a couple of reviews mentioning terrible vibration of Deck 13 of the QM2. The reviews state that the vibration was bad in the harbour as well as at sea and that people were moving cabins. They also said that Cunard were aware that there was an issue. I've just booked a club cabin on Deck 13 rather than 12 as I read that the shower cubicle has a door rather than the shower curtain.

 

 

Does anyone have any experience of this? Cabin 12024 was mentioned.

Structural harmonics are a well-understood engineering phenomenon, explained better by chengkp75 than I could do.

"Vibrations can be caused by a few things. One is the infamous "azipod shimmy", which is caused primarily when the ship is in following seas, and to keep a constant heading, the azipods that steer will "sweep" back and forth, port to starboard and back, as the following seas swing the stern one way or the other. This constant sweeping of the propellers causes the water flow into and out of the propellers to sweep across the flat hull above the pods, and the ship vibrates horizontally. More noticeable the further aft you go. This problem was so severe on the QM2 at sea trials, that they had to take the ship back into drydock and add a "skeg" or vertical portion of hull between the port and starboard azipods for more lateral stability."

 

"The other vibrations are because the ship is a large "sounding box" like a violin or guitar. Externally produced vibrations, like the blades of the propellers passing the hull at the top of their rotation, or periodic waves striking the ship, can cause the ship's hull to vibrate. Due to the complex nature of the hull structure, various areas will have different natural frequencies, and so will start to vibrate at different times when different frequencies are induced. So, combinations of propeller speed, wave period, wave direction relative to ship's course, and the like will vary the input vibrations, and consequently an area might vibrate in the morning and not in the evening, if the environmental conditions change. Similarly, one cabin may vibrate at one speed, in a given weather condition, but not another cabin down the passageway, but if the propeller speed changes by a few rpm's, the second cabin may vibrate while the first does not."

Having said that, it seems unlikely that a "terrible vibration" would manifest suddenly on the QM2, unless they'd just lost a propeller blade or other significant event. Particularly on the upper decks, where any such vibration would be felt immediately by the OOW in the navigation bridge, mere steps away. By altering the engine speed by a few RPM, they could correct any harmonic vibration in seconds.

I don't suppose you could provide a link to any such reviews? I haven't seen any here on CruiseCritic.

Tell you what, I'm joining next week on Deck 12, forward. I'll report back if I am shaken out of my bunk.

Also, upgrading to a Club cabin (at considerable expense) in order to get a glass door instead of a shower curtain??

That's like upgrading to a Queen's Grill suite in order to get flexible dining hours.

I sure wish I could afford such a bespoke lifestyle!

Here's a link to one such QM2 review I found from April. It discusses cabin 13024 which is probably what the OP meant (rather than cabin 12024) since the subject of this thread mentions deck 13. I have no personal experience to offer on this subject--just providing this link to possibly aid in further discussion.

Quoting the pertinent section from this review:

 

"Further to the stateroom there is significant vibration most of the time which is apparent to both port and starboard. Theses [sic] staterooms were a recent addition made during the last refurbishment. Cunard of course are aware of this and I'm told by a guest services executive that they are looking at ways of factoring it into the brochure stateroom descriptions. Too little to late for us, Cunard got our money, my wife got no decent sleep. As a matter of interest the vibration has nothing to do with sea conditions as it was present when the ship was on its mooring lines."

Thanks for that John, it was very helpful to see the cited reference.

 

Clearly this was not a "whole ship" vibration the beleaguered passengers experienced; if not connected to the propulsion or the ship's motion then it sounds more like a rattle in the paneling or duct-work or fittings or something ... presumably linked to the HVAC system, since what else would be running while the ship is alongside?

Or maybe it was the shower door rattling (sorry, that was a cheap shot from us mere shower-curtain hoi polloi).

 

 

Annoying all the same, but often it's nothing a square of wadded-up paper won't resolve, so long as one has access to the source.

 

 

Judging from the rest of Brian72813's review, it sounds like he arrived for his Cunard experience with high expectations, which were clearly not met.

 

I am eagerly anticipating MY first Cunard experience next week.

Luckily after reviewing the CruiseCritic archives these past few weeks, I come forearmed with the sure knowledge that I will be inundated and besieged by under-dressed, poorly-fed, over-charged, prematurely-embarking disgruntled passengers surreptitiously sneaking glasses of wine from stateroom to dining room.

Anything above that low threshold should leave me delighted.

 

Cheers!

I interpret the OP's comment differently. " I've just booked a club cabin on Deck 13 rather than 12 as I read that the shower cubicle has a door rather than the shower curtain." I get the impression that a club cabin was going to be booked and Deck 13 was chosen over Deck 12 for the reason given. The A2s are the same price whether on Deck 12 or 13.

 

 

But I digress. In October 2016 we had cabin 13035 which is on the starboard side. We noticed no vibration at all. At that time the Deck 13 cabins had been in service for only a few weeks so the vibration issues must have developed since then.

Fair enough, that sounds plausible.

Hi Soraya,

We were booked and sailed last July on Deck 13 and were in 13002. Yes the cabin were new from the refit and the Bathrooms did have the Glass Door instead of the Curtain. We were very happy with the assigned cabin thru guarantee status and enjoyed the experience. Yes we did first have reservations about being up there but had no regrets.

 

We did not feel any vibration in that cabin for the 6 days we were in it.

We did also sail on Deck 12 in Cabin 12052 in the past and had no vibrations.

 

We are assigned to Deck 12 once again on our upcoming sailing and look forward to the experience of Club Britannia.

 

Hope you have a pleasant and smooth sailing during your voyage on the QM2.....

Thanks for all the replies! I was indeed booking a Club Balcony cabin and chose deck 13 over 12 for the shower! Interestingly, not a big price difference on our sailing between Club and standard balconies.

 

 

Hopefully, the vibration issues will be be absent on our cruise. Enjoyed reading the v technical thread on vibration & harmonics!

 

We actually have booked 13035 so really good to hear from someone who has stayed in it.

 

 

VintageCCG - we did our first Cunard cruise this year - 4 day cruise on the QV from Southampton to Hamburg and really enjoyed it. Hope your 1st Cunard cruise is a good one and I look forward to reading your review which I'm sure will be in your own inimitable style:cool:

We have just got off QM2 today and were on Deck 13, Cabin 13012.  That is forward on the new top-row of cabins that were added in the last re-fit.   The vibration is DEFINITELY an issue to consider.  Had no idea until we were on board.  It is not constant, but it IS frequent and it IS quite severe at times.  So bad that the TV rattled and we had to stuff a rolled-up towel behind it.  The bed vibrates like one of those therapy beds and it drums through your entire body.  It woke me up on several occasions and when it was present before going to bed, you could not get to sleep.  You can feel it in your chest and it made us both feel sick. The floor by the sofa also shakes.   It was obviously an issue for previous guests as tape had been stuck over the corners of the full length mirror which housekeeping had tried to remove but failed.   And Deck 13 are all Britannia Club cabins, so more expensive.  I am shocked to read this Cunard have been aware for 2 years.  They have clearly done nothing about it.  I wish I had read this post before we set sail, we would have asked to change, but once on board the ship was full so no chance.  The cabin itself is nice, yes there is a double shower with glass door (where bath would normally be) and marble tops to the basin and bedside units.  We found storage space to be an issue as they have changed the wardrobe layout in these new bolt-on cabins on the new top-deck, there are no shelves and the safe is much lower.  Personally,  I would  never book one of these again as the vibration was present at some point every day and every night lasted for quite some time, hours in some cases.  It was there in  both calm and choppy waters, and also in the port when stationary.  We will be writing to Cunard for sure.
