As promised here are some pictures of my time at sea with those massive dirty diesels...

New piston crowns

Diesel Generator No.1 MAN B&W 48/60 V14

Mate standing on the engine

Me, some of the lads and a piston

Looking down the bore of the cylinder, you can see the crank at the bottom

Piston

Me in the crankcase, sorry about my lack of modesty! It was hot...

Piston with brand new crown

Big pistons need big...

Cylinder head

Piston pin and a proper pair of micrometers!

Crankcase

Propulsion Motor

Con Rod

Radiator/heat exchanger for engine

And there you go, a sample of large scale engineering!

How many gallons per mile? :biggrin:

And what fine vessel does this engine belong to???

You a Marine Engineering Officer i guess then?? Planning a full career in it or using it as a stepping stone to better things???

Awesome pics!

8 tonnes an hour, about 30 miles an hour.

Around 2500 gallons an hour, so 0.012 mpg :biggrin:

MV Aurora.

Oh yes, and planning a career in it and will probably use it as a stepping stone into Formula 1 or some other engineering route shore side. Too much time away from home otherwise!

good money while your offshore!! I presume youll be ensureing you get enough days in your first few years to get tax free???

You could always go RN Submariner and specialise in nuclear engineering!! big money in civvy street and no shortage of jobs!

Oh yes, all tax free. Over 6 months at sea.

3 months on, 2 months off.

RN is too dangerous for me, submarines are cool, but a ship full of men under water for extended periods without any views and limited communication. I would rather not. I might go for the RFA though.

There is never a shortage of jobs in any engineering tbh, as cool as nuclear engineering is!!

The shear scale is amazing. Wouldnt mind doing that job myself as long as it wasnt with other sweaty men in boiler suits playing with their tools lol

You get used to it, in the first week it is a bit sore, but after that, its all good with other men's tools!

But yeh the scale is simply immense, the 48/60 part of the engine means it the bore of the cylinder is 48cm and the stroke 60cm. I.e. a foot and half by over half a metre.

Oh yeh...

And those propulsion motors? They need 2200V, and around 1500Amps to run, and at maximum chat, use 20MW of power. We have 2 of them, so 40MW of power. That is enough power to light up Southampton.

So how many revs, bhp and torque do they have?

Too big for my liking. Looks a bitch of a job compared to faffing with 10 litre engines we play with at work. Interesting pictures though.

Surely the more important question that we've all come to learn is crucial on this forum is- does it have vtec?! (yo!)

Well if it was VTEC it would only need to be the size of your fist to generate the same amount of power! :yes:

The engines drive generators, so torque I don't know, but they run at 514rpm, they have around 20,000hp each which generates about 14.5MW of electrical power. There are 4 engines. So 80,000bhp in total, 48MW.

14,500,000 Watts in other words. That is a a lot of light bulbs...!

The motors which drive the ship, have about 1400KNm of torque, but can go up to 1600KNm in an emergency. Each motor is about 27,000bhp each. Max revs are 140rpm.
