Worlds biggest container ship...........pretty sad really

[gordon stephenson]

Two lorries, Thornycroft and commer at least used diesel 2 strokes. The Commer S3 had 3 cylinders with opposed pistons, When I was a teenager a local haulier had a few, Most wonderful exhaust note when they were under load, Google Commer S3 and listen to some of them on youtube.

I thought that 2T diesel was just someone not understanding the difference between the two. Seems that someone was me. Interesting reading though.

That Global is a proper massive vessel. ?Would anyone like to hazard a guess at the stopping distance at its' cruising speed of 19km/h? I would not even like to think of doubling that speed to its' maximum.

Most of you have seen the models I was making in the 80s, for Swan Hunter et al, well one of them, The Atlantic Conveyor is still pootling around, due into Liverpool from Hamburg today. That is thirty years bobbing around on the briny. Being G3, it is positively tiny by todays' standards.

Land Rovers are built by Swedish robots

When Rover opened the new Metro plant in 1980 the underframes were built by 2 German machines, the doors by Dutch machines and the bodies were welded on 2 French supplied lines using American robots!.

and rusted by English weather

The Commer S3 had 3 cylinders with opposed pistons,

flat engine 3 cyls and 6 pistons and no need for cylinder heads. and only one crankshaft
I remember sorting one out, years ago as an apprentice someone had fitted a starter motor to it and it would turn over, but wouldn't start, they did all kinds of checks including easi start etc, no go.
I was listening to the exhaust note and said give me the easi start I squirted it up the exhaust and it fired !! didnt let it start though.
Turned out ( yes a pun) that they had only fitted a starter that looked the same and hadnt checked the direction.

Or the deltic engine...

 

[daleyd]

I remember the old deltic locos thundering past our village from my youth, classic piece of british engineering and ingenuity!

And they sounded fantastic when they had the taps open!!

Here you go it's Renault who are developing one for cars.

Can't appreciate the size properly...........needs a builders mug for scale.

Interesting post...

I used to load one with steel to go to Sheffield and you could hear him coming down the bypass 10 minutes before he arrived at the plant. It absolutely screamed.

So what engines are going in the new aircraft carriers and who makes them anyone in this country?

So what engines are going in the new aircraft carriers and who makes them anyone in this country?

Propulsion: Integrated full electric propulsion

2× Rolls-Royce Marine Trent MT30 36 MW (48,000 hp) gas turbine
4× Wärtsilä diesel (2× 9 MW or 12,000 hp & 2× 11 MW or 15,000 hp)
4× Converteam 20 MW Advanced Induction Motors

Queen Elizabeth-class aircraft carriers according to Wiki. Whatever all that means.

?Perhaps they are remote-control too?

GAS turbine?? I wonder what sort of gas.I always though turbines powered by gas had to be stationary.

They use a heavy fuel oil called dieso, a bit like rough aviation fuel!

A Gas Turbine is an internal combustion engine, the 'Gas' bit refers to the fact that the working fluid for the turbine section of the engine is hot gas rather than steam or water. There's a good Wiki page which explains more http://en.wikipedia.org/wiki/Gas_turbine

p.s. Gas turbines typically burn all sorts of fuel gas, as well as distillate (diesel) and heavy oil, but will work on pulverised coal although this does tend to wear the blades somewhat

marine version of a jet engine IIRC

invincible class had marines versions of the engines fitted to concorde....

The invincible class had a conventional arrangement with the gts (4 x Olympus) being connected directly to the gearbox and shaft, the newer class has the gt connected to a generator and an electric motor on the shaft.

The invincible class were no slouch for pretty big ships, but my favourites were type 21s - proper fast ships! There were stories of people waterskiing behind those!

I watched a documentary on one of the ships, when the captain was asked how much fuel it burnt, he said at flank speed about 17 yards to the gallon!

I remember watching the same one, about hms fearless (old assault ship, now scrapped)if i remember correctly?

That was the last RN ship to be powered by steam turbines, with oil fired boilers. Proper old school!

Type 45 destroyers are similar, gas turbine electric hybrid, very agile class...turns surprisingly quickly for a 7,000 tonne ship....

IIRC the accomodation on the Type 21s was designed by a woman, accounting for why it was much less spartan than MOD designed ships...modern stuff is just catching up now...
Guys on Type 42s slept on something like 30 odd man messdecks....

The type 21s were civilian designed, not done in house by the mod. Dont know about the woman bit but it could well be true! They were always well liked by those who were on them, i think some might still be going after we sold them to pakistan in the early 90s

On the Argyll as an apprentice i was in a 39 person mess - probably the total size of a decent double garage !!

It wasnt the most pleasant of places' especially after a night of shore leave somewhere foreign!!
