UK’s biggest warship suffers propeller shaft damage off south coast after setting sail for US

I expect that they knew that the ship hadn't grown.

And one would have hoped they took a few photos of the actual tide heights on the bridge piers when first came out, and compared to check actual tides when coming back in

They sent the Navigator on a Day Skpper course.....

I believe the Queensferry Crossing has the greatest airdraft clearance below of the three, by about a metre...

They must have been confident, they didn’t even close the bridge to traffic

And it seemed to be travelling at a fair pace.

It is slightly more technical than that. Forth Ports have calibrated tidal gauges at various ports from Methil up to Grangemouth and as part of the Quality management system the pilots confirm these tidal gauge readings as they make passage upriver. No need for a man in a boat and tape measure at a bridge pier. No doubt this modern ship has draught gauges in the control centre so no need for a sailor to hang over the side in a bosuns chair to read draught marks. Easy enough to confirm the air draught.

Interestingly the crew and all their stuff is onboard…if the carrier was empty would it hit the bridges??‍

Why didn't they show a photo from the other end ?

Now for the post-mortem and finger-pointing.

I hope that it's so, without a cover up, without any procurement/design/fabrication sign offs being ignored, and without any corporate failing being unaccountable.
If there's a fault from a contractor, that contractor must be held accountable and forced to reimburse for costs, including the cost of the inquiry.
If it's the case that this is a repeat fault, surely it's correct to find out why it happened?

 

[penfold]

Not aware of another instance of a muff coupling failing; have I missed it?

Started..
The £3.2bn warship that’s all at sea (sorry about the paywall but the relevant paragraph is there)
The ship builders are blaming the navy

Why does PoW have two towers (for want of a better term) but the US aircraft carrier has only one ?

The RN/FAA specifically wanted to separate the duties of flight and ship control, rather than have them cramped in one location

So they both have their own tower and full viewing deck

This is why I don't buy a paper any more, the risible "gotcha" writing.

The Ministry of Defence has failed to provide a date for when the Nato flagship will rejoin the fleet.

It's juvenile garbage, the ship has just docked with unknown damage and it will be days if not weeks before the full workscope can be planned.

Now it has emerged that concerns were said to have been raised about its propeller shaft three years before it broke down outside Portsmouth this month. Industry partners wanted to carry out further tests, according to a source, but the navy, desperate to push ahead with its programme, declined.

Francis Tusa, a defence analyst, said the navy appeared to have “underestimated” the shaft problem. “With every ship that gets delivered there will be something here or there that is not perfect,” he said. “Some of them are really easy to solve when the ship is in service, others take more time.
“There are some signs the Royal Navy underestimated the problem with the propeller and the shaft and assumed it would be far easier to resolve than it has turned out to be. It certainly seems to be the case that they took responsibility for the ship too early.”

In the name of the wee man; the scribe has devoted 2 bloody paragraphs to telling me nothing but vague innuendo.

A navy source disputed the suggestion it had taken delivery of the ship too early and said that an internal report found that although questions may have been raised about the shaft initially, “there were no issues with the shaft line” and “vibration measurements remained well within limits”.
The 129-page document, “Learning from the Queen Elizabeth Class programme and the Aircraft Carrier Alliance”, covered the period from 2013 to 2020. Babcock, the firm responsible for the shaft, declined to comment.

Wow, so much detail, I'm overwhelmed by their comprehensive, incisive and forensic grasp of the issue. That's the sum total of the article's covering of the alleged dispute, the rest is warmed over tripe about stuff that happened years ago during commissioning. It's also a terrible abuse of the english language "as she is wrote"; Larisa Brown earns a living writing yet is very bad at it.

Now it has emerged that concerns were said to have been raised...

It's english but communicates nothing.

Has the Royal Navy been shafted by Babcock?

Might let the cat out of the bag!

If it moves, salute it. If it doesn’t move, paint it. If it moves after you’ve painted it, hide.

Or oil it?
(but only if it is non human )
