Google Maps latest photo shows the two dry Docks in Oman to be filled with several oil tankers.....in questionable states of repair.

So it would appear that 23 Million UKP investment might sound good....but reality would suggest being able to get your prized aircraft carrier into one of them on very short notice would be about.....well.....Nil.

One day he'll finally admit to having been cucked by a member of the RAF.

Google maps. Rigggghhhht.......

Are you suggesting that drydocks just stand around empty, waiting for a carrier???

Not a Boffin,

Was that a serious reply?

What shall the RN get for its 23 Million UKP expenditure re Dry Docking?

What lead time is required to get a Carrier into either of the two Dry Docks at that location?

What technical capabilities exist at the Yard?

About as serious as using Google maps as a reference. Lead time days. It's a repair yard, not build.

Have a look who operates the yard....

Reading the Navy Lookout article concerning the coupling failure it all starts to make sense. I've seen a number of sea water cooled couplings fail, the usual cause has been a constriction within the cooling pipework usually as a result of internal corrosion of inadequately galvanised components. This leads to a reduced flow and ultimately an over heated bearing/coupling. In a worst case scenario this could lead to a scored shaft and the need to remove the shaft and dress out the damage. The last time I oversaw such a repair the shaft had to go overseas as no UK facility had the infrastructure or experience to carry out the work.

Surely this provides a wonderful training opportunity...or something?

No. Initial vibration on QNLZ trials caused by incorrectly seated prop blade, leading to discovery of unrelated thrust block issue - both understood and sorted.

On PWLS it is a different issue, different cause - and fairly unusual.

We might hope that it is VERY unusual. The tax payer has not had a very good return for the massive investment.

Like any Defence item the return is mainly from the production and heavy maintenance stages in the form of jobs and maintained skills/expertise. After that it is like an insurance policy or a guard dog. Costs money to keep and you hope you don't need it.

Rear Admiral Steve Moorhouse delivers the latest update on HMS Prince of Wales

https://twitter.com/i/status/1565747919810138113

Significant Damage to the shaft and propeller and superficial damage to the rudder.
Perhaps those on here more qualified than me, could comment on whether this could have been caused by a failure to grease the shaft, or was more likely caused by striking a submerged object.

Just as well we had a spare available to send Stateside

Not to do the SRVL trials though, as Queen Liz doesn't have the full Bedford Array system fitted.

It's a sea water cooled coupling, so there's no requirement for it to be greased. What with all the sea water surrounding the ship.

ABB,

No Temp sensors on the shaft bearings or similar water cooled running gear?
