Anyone ever been involved in a large construction project - whether land or water based? Even our new nb was having snags fixed by the builder several months after handover (only a very small number I hasten to add in case anyone can work out which builder it was!). I knew they should not have gone to "Springer's" for the job. Link to comment Share on other sites More sharing options...

Yes this morning a BBC reporter was yapping about how much Bitcoin are now worth. 2000 times the original value apparently "That's two hundred thousand per cent" he said. I'm surprised they haven't invented 'micro per cent' or some other ridiculous unit so that they can quote as big a number as possible. Link to comment Share on other sites More sharing options...

howardang Posted December 20, 2017 Report Share Posted December 20, 2017 On 19/12/2017 at 06:50, Alan de Enfield said: If it indeed it is a stem gland then presumably it is a bow thruster rather than a prop-shaft - typical poor reporting The report says one of the propeller shafts - she has two fixed pitch propellers driving through conventional shafts - so not poor reporting and it is not a bow thrust. This is a typical sensationalist report by the press about what is a nothing story. 200 litre per hour through a stern gland, although not desirable, is small and easily coped with. The amount of guarantee items on the list before the vessel is 100% will make this "incident" pale into insignificance. See the pic below from the BBC report which shows the shafts Howard Link to comment Share on other sites More sharing options...

But the thread title is STEM LEAK. Just in case you don't know,, the STEM is at the font of the boat - so, if the leak is at the 'back ' then it is poor reporting Edited December 20, 2017 by Alan de Enfield Link to comment Share on other sites More sharing options...
nb Innisfree Posted December 20, 2017 Report Share Posted December 20, 2017 Two spanners required, one for the locknut and each one needs 10 men to lift, then another 10 to actually turn the nuts. Link to comment Share on other sites More sharing options...

The BBC report quoted in the thread clearly speaks about one of the propeller shafts which, in my limited experience, are at the back of the ship, but no doubt you will correct my ignorance if I am mistaken, and thanks for telling me about the Stem.

Tony Brooks Posted December 20, 2017 Report Share Posted December 20, 2017 I think some European lake steamers and some ferries have shafts and props at the front as well as the back but I expect modern ones have swivelling electric propulsion pods instead.

Many do. The Woolwich ferries have four swiverable units, driven by a couple of Davey Paxman Valenta diesels, same as what the HST 125 trains used to use. Most railway diesel loco's use engines that were primarily designed for marine use. Paxman, Sulzer, English Electric, GM. Link to comment Share on other sites More sharing options...

The present Wolich ferries have Voith-Schneider units to give very good manouverability. According to recent reports their replacements will be diesel electric with azimuth propulsion units.

Tony Brooks Posted December 20, 2017 Report Share Posted December 20, 2017 Many years ago I organised a visit for the engineers and apprentices at the boatyard to a single screw Union Castle cargo ship in the London docks. Apart from the fact that the only engines we could easily relate to were the ones driving the refrigeration units what struck me was just how much water leaked through the stern gland. There was a fair flow running down the shaft tunnel and probably far in excess of 200l/h so I thnk this is a non-story Link to comment Share on other sites More sharing options...

davem399 Posted December 21, 2017 Report Share Posted December 21, 2017 (edited) Many moons ago, I was at sea in the Merchant Navy, and a number of our ships had Paxman diesel generator sets. They were a bit of a nightmare to run and maintain. I always remember the turbochargers glowing cherry red when under a high load.
