content: Reminded me of the George Eastman house (Kodak museum) where the house was cut in two to give the ballroom better proportions.In 1919, George Eastman sought to enlarge the conservatory in order to make the space oblong rather than square. His architect at the time, William G. Kaelber (1886–1948), drew up plans to cut the house in two and move the rear section 9 ft. 4 in. to the north using horizontal hydraulic jacks on railroad ties with special wheels and tracks. The project cost $750,000 and took approximately three months.

content: I know of a manufacturing company that needed to add a large expansion but had no more ground space. They couldn't add another floor to their existing two story building because the new equipment would be heavy and the upper floor could not handle any more weight. So they cut the upper floor loose, jacked it up, and built the new floor in between. It worked out well and they were quite proud of their results.

content: Quote from: Lord of nothing on March 20, 2018, 04:23:59 pm1) Metric measurements only became official in the UK in 1971.2) The house being described is in the US and it's a historical account. Those are the units that would have been on the plans.3) 9 foot 4" is probably not an exact figure. Whenever you have to do this kind of conversion you either get an over precise answer (2.8448m) or an inaccurate one (2.8m). Quoting either figure would be misleading whereas 9'4" gives a feel both for the size and precision of the measurement.4) Are you going to do thiseverytime someone mentions a non-metric measurement? I ask, because I've spotted it from you often enough that it's beginning to become annoying. I may be forced to adopt a policy of posting only in pre-SI units (dynes, Oerstead, Maxwells, mhos etc.) in retaliation.

Oh, and for pints of beer, proper imperial pints (568ml), not those puny colonial pints you have over there (473ml) or the stingy 0.5l or 330ml used by Johnny Foreigner.When I was at school, many of the older textbooks still had cgs units in them, complete with all the constants needed just to make the units work. Yuck. Imperial units have a nice feeling of tradition to them, SI units just make sense and cgs units were clearly invented by misanthropic physics teachers who had sold their souls to some nether dwelling creature of their own foul imaginings.

content: Back to the subject in hand.One part of me thinks the idea of a perfect cross-section through a cruise ship is the best thing since sliced bread. Another part of me mourns the fact that it's going to enable an even bigger oversized cruise ship to be born, full of the kind of tourists who 'do' somewhere like Venice while their cruise ship dwarfs the local architecture. So I'm in two minds.I'm reminded of the sections of transatlantic telegraph cable that had been cut through and the ends polished that I first saw in the Science Museum in London when I was a small boy. That in turn reminds me of the cut-away diagrams that used to regularly feature in popular science magazines, Sunday colour supplements and boy's comics of a certain age. I do love a good cut-away diagram but you hardly see them any more. A shame.

Ever wondered why you can buy 19.05mm pipe ? some things change slowly because industry is not going to suddenly swap all of its equipment, feet is still widely used in some industries. And before people whinge about them being british imperial impositions remember we inherited them from the Romans so if you think something that has been a standard for over 2000 years is going to disappear just like that think again. I can use both and find thinking in units of inches and feet handy for stuff that is "yay big" but actual measurements are taken in metric and yes at work we are having problems with 3 inch pipe and 76mm hose......So quit whining about it please, we all have to deal with it anyway.

If I feel especially annoying, I will subtly slip in a helping of colourful British spellings and pronunciations in.Anyways, to the topic of this. Idk, whenever I see a modern cruise ship, especially like this, it just reminds me of the Costa Concordia. Ships are major elderly magnets, people who have a load of retirement money, and a load of time, two things that mean opportunity to anybody fluent in capitalism.This is cool though. It seems a bit crazy and flush with technological hurdles, but they are the shipyard, and they know how to what do.

content: I miss ocean liners instead. As the name suggests, these ships were meant to take on both pleasure seekers and travelers alike along with cargo across the ocean. The reason why we (stateside) moved from this to cruise liners was mainly due to us drinking the boeing redbull during the 50s-70s. Only pleasure current year folks get from boats nowadays is island/port hopping.

content: Submarines in the US have been made in slices that are then assembled since the 1970s. Lets the slices be built in parallel allowing shorter construction time. Amazing number of pipes and wires to splice, but it all seems to work out.It always impressed me that over much of the world and most of the submarine designs, when a major piece of machinery needs to be replaced they just cut a big whopping hole in the side, pull the old gear out and slide the replacement in. They weld the hole back up and then back below the waves. Lots of people depending for their lives on the welders and weld inspectors. Now the same thing applies to wealthy tourists.

content: Well, modular construction is good especially for a design where you make essentially multiple of the same thing. Great for VLCC and cruise ships, where the majority of the vessel consists of near identical tanks for the VLCC and stateroom blocks for the cruise ship. As well you can do things out of sequence, so can do the fitment of most of the rooms before they are part of the structure, saving weeks of fitting overall, plus you can also do multiple things in parallel as well, cutting the assembly time.As to the major items that are generally designed in as lifetime parts, like the main engines and such, those are often serviced or replaced using the "cut the big hole" method, either taking out deck blocks above the engine compartment, or making a big hole in the side and having a bespoke designed gantry crane built into the side for the job. Pretty every other thing that the designers think might fail during the design life ( which for a big ship is generally 50 years, as the vast majority of the systems on the ship are designed to be upgraded during the ship life, as technology changes) they make sure there is enough room to get them out without too much dismantling, or make the stuff easy to remove to components in situ.I am more impressed by the fitting together, with all those parts going together so well first time, points to them making some fairly detailed and precise fitting and assembly jigs that the internal parts have to align with during manufacture to pass QC. Makes maintenance slightly easier, as you only have to go to a flange when doing work involving pipe replacement, and also will likely have isolation valves for all plumbing per section, as that allows easy testing during assembly fully made up, and leaving the valves in place is cheaper than having to remove them.

content: Quote from: Cerebus on March 21, 2018, 04:32:44 amSorry about the foggy brain. The 26C came from my long association of the nice round number of 300K with normal temperatures on earth. In texts here in the US 23C is usually associated with room temperature. My personal room temperature is 66-68F in the winter when I am paying heating bills (often in the form of chopped wood) and more like 80F in the summer when I am paying for the chiller. Apologies also to all of those offended by the use of units other than their preferred standard. I am sure the US would be quicker to change if you footed the bill for replacing all of the installed base of thermostats and such, plus re-education for the ancients who grew up on the older system.I am totally in agreement with use of metric for measurements of mass and distance and all of the units that can be derived from them. But the temperature systems (all of them) are purely arbitrary. A metric temperature system would allow determining the temperature rise of a metric volume, cc or m^3 of water without fudge factors.

I was working on a navy ship refurbishment, and to get the generators out to recondition them, they just cut a big hole down through the decks to the engine room. Then welded it all back afterwards.Slight goof - they'd assumed the junction boxes sticking out the sides of the generators, where all the field coil cables terminated, could be removed. They cut the deck holes on that assumption. Then it was discovered (by me when I had the job of removing external cables from those junction boxes) that the internal wiring (big fat stuff) coming out from from the coils could not be flexed because all the insulation was rigid.So they cut extra ear-shaped bits out of the decks.Quote from: BravoV on March 21, 2018, 04:41:53 amOne USB cable should do it.Btw:https://www.cruiseindustrynews.com/images/stories/wire/2018/mar/SSpir_20180310_1247_8MP_JH5.jpgNice clean big photo of the ship cut.

content: Quote from: Cerebus on March 22, 2018, 02:46:12 pmNo. Really, ship maintenance is a chaos. Some more stories. It's a while ago now, so should be OK.Photo below is what happens when... one of the big diesel engines of a warship is serviced by unskilled naval personnel. After a major engine refit, someone reconnecting lubricating oil feed lines forgot to remove a cotton plug from the end of a line. Ship set off on deployment. They noticed some overheating in one section of the engine, did nothing. Under full power, a piston seized in the cylinder liner. The connecting rod ripped the gudgeon pin (seen in pic) out the bottom of the piston. Flailed around in the crank case, taking divots out of the steel (visible in pic.) Gudgeon pin came loose, added to the clanging. Until it got jammed between a crankshaft lobe and something solid - where it is still solidly wedged in the pic. They'd taken out the liner, piston, and connecting rod, could not get the gudgeon pin out. Wish I'd had a ruler for scale. You don't get a sense for how big that is.Whole engine had to come out AGAIN and be refurbished AGAIN.Photo was taken with permission.One time I was asked to remove all the thermocouple sensors from a main propulsion gearbox, so they could be sent off for calibration. About 12 of them. There were no numbers on them, or the mount points, no plans that I was told of. So how to ensure each one went back in the right spot?I numbered them all, drew a sketch of the gearbox (it's about the size of a VW beetle) with all thermocouple mount points marked and numbered.My boss the electrical works supervisor, said the cal lab were amazed. Never seen anything like it. Usually just got a box of random unmarked sensors to check.A big ship's loading crane, with a strain gauge in the pin through the boom end pulley. The lift weight meter and overload safety circuit in the crane cabin was orphaned - manufacturer gone, no schematics available. And the card had gone faulty. Guess who had to reverse engineer the circuit, work out what was wrong, fix it, reinstall, then.... recalibrate it.You know how they calibrate a ship's crane strain gauge?A giant water balloon, and a known accurate strain gauge with radio send. Put that on the hook, hang the water balloon from it, Swing crane to ship's centerline, fill bag... But the cabin gauge circuit has span and offset adjustments. So it's unavoidably an iterative process. Fill the bag, empty it... repeat.And if they swing the crane to the side while full (to empty it) the whole ship lists about 20 degrees.I think every sailor on the ship hated me that day.Also I got a black mark with my employer (ship's shore maintenance co) for giving the circuit to the ship's tech, rather than keeping it with the shore maintenance co. Sigh.Couple of the ships had a special chair for the captain on the bridge. They were recycled business class airline seats. Very plush, and with every imaginable motorized adjustment. Except... all that active seat electronics expected to be talked to by the plane computers. Seat arm controls --> plane computer --> seat motors. Or maybe it just needed to be told it was OK to move, I don't know. But there wasn't even any connection to the socket in the base of the seat. So it was just dead, set in one position.Discussing with the ship's tech guy, I offered to see if I could hack up a box to make the seat electronics happy and working. To assist, could he ask the airline if they had any tech info on the seat interface & protocol? He tried inquiring. Guess what happened?It sent the ship's intelligence/security officers into a frenzy. WHY was he asking about that? Who was he talking to about it? Why? He was told to drop any thoughts of such a project.Plenty more stories...Working on the ships was a lot of fun, for well over a year. I'd started out employed by a refit contractor (Forgacs) then got contracted to do various 'no one else would do it' jobs. Which I was doing for way under the rate any company would have wanted, because I liked it so much. Then they decided they'd get me a proper pass to the base. So did a formal security check. Ha ha, oops. They don't tell you, but I gather I failed. Something to do with associations and stuff I suppose.

I can almost positively guaranty that something you use in your everyday life has a inch system part in it somewhere. NPT and BSP are still the most widely used type of pipe thread as a example.Also metric has its failings. The thread system has some good and some bad. Wire size in mm/sq why not just give me the dia. that way I can just measure it.Oh and NASA. As someone pointed out in a metric fanboy thread somewhere. The engineers may have designed it in metric but it was almost certainty built in inch.

content: Easy to cut holes in a ship, as most docks are very well equipped with the good old fashioned gas axe, in sizes that range from small (only going to cut a quarter inch of steel) and going up from there to ones that require the use of a crane to move the cutting head, and where the gas supply comes from cryogenic tanks and a vapouriser, and where you burn a cut through 10 inches of steel without any problem. Cutting through the typical half inch single wall steel of a ship hull is not something they are inexperienced with, and there are a corresponding team of welders who will come and fix the patch back in afterwards using a really big arc welder, and a whole load of welding rods, or a roll of welding wire and shield gas to fill the gap up.Of course you then get the guys who come, remove all people from the area, put up the barrier tape and signs and then bring in the Cobalt60 gamma source to check the welds afterwards. There are quite a few times those sources have been stolen from the yards by those who are after the stainless steel of the housing, and who are blissfully unaware of the meaning of the symbols on the container and the warnings. that is why you find scrapyards have Geiger counters at the depots, to find any of those contaminated loads. Bad day for all concerned if that detector reaches the trip level, there is a pile of bovine product that just gets deeper as time goes on. Nice area in Brazil, that is a park now in a poor area, where the one was opened.
