Bee Posted November 26, 2016 Report Share Posted November 26, 2016 Apparently one of the new Type 45 destroyers has had to be towed back into Portsmouth, seems that the engine (s) have an overheating problem. Blocked filters? Impeller? I don't suppose many of us are familiar with Type 45 destroyers, I'm alright with BMC's and a few others but I'm stumped with this one. Anybody got any ideas? the things cost £1billion each so I expect the navy would appreciate some suggestions. Link to comment Share on other sites More sharing options...
WotEver Posted November 26, 2016 Report Share Posted November 26, 2016 Interesting. They have RR turbines as well as diesel generators so I wonder if it was the pods that were overheating as opposed to the engines? "Total Propulsion Failure". I guess they can't afford any spare fuses. Link to comment Share on other sites More sharing options...

Tony Brooks Posted November 26, 2016 Report Share Posted November 26, 2016 I understand that recent new Navy surface ships have not had sufficient generating capacity so with "everything" running suffered generators shutting down on overload. I thought that they had cured this but maybe not. If the generators are overloaded I would expect a fall in voltage and from that overheating of motors etc. as well as the generators themselves. Just conjecture in respect of the latest reports. Link to comment Share on other sites More sharing options...

OK there must be a split in that funny canvas tube thingy that leads up to the pidgin box in the engin' room roof. .............Dave Link to comment Share on other sites More sharing options...

Stormbringer Posted November 26, 2016 Report Share Posted November 26, 2016 The American version was no better...think that had a leaking stern gland ! No...really! Broke down in the Panama canal with water ingress through a bearing ...only cost about a trillion dollars lol... Link to comment Share on other sites More sharing options...
MHS Posted November 26, 2016 Report Share Posted November 26, 2016 They could try running some hot water into the galley sink. This would empty the calorifier and help cool the engine. Link to comment Share on other sites More sharing options...

mross Posted November 27, 2016 Report Share Posted November 27, 2016 She has two gas turbines and two large diesel engines each providing electrical power to the two propulsion motors. The motors comprise two half-motors each so there is a lot of redundancy built in. This propulsion philosophy is common on cruise ships and has proved to be effective. I'm amazed that she lost all propulsion. I read in one paper that a sea-water cooling pipe split. Link to comment Share on other sites More sharing options...
