Large engine tour.

[Ed]

I was taken on a tour today around a ship by Andrew (who occasionally posts on here, basically this ship engine is 73726bhp, (55MW) inline 10 cyl, runs at 96 rpm, There is a pic of me standing next to an exhaust valve, and a pic of the top 1/3rd of the engine.

Impressive stuff it has 3 massive turbos that run at 2 bar boost

best i ever seen was 2 V 20s side by side but hey were not as big as that!! nice pics

this boat also had 4 main generators which generated 2.8MW of elec @ 6200volts each!

One of the 3 main engine turbochargers. They spin at up to 9000rpm to provide boost at just over 2 bar.

Tachometer and rev counter - it does 100rpm at most in either direction.

Looking up from the bottom of the engine to the top.

The propellor shaft which is solid steel and about 1m in diameter.

The power meter. Reads in MW. We were coming alongside when I took this, so only 14MW being developed. Just so we are clear, this is the "power at the wheels figure", no dodgy correction factors.....

Top of the engine. 10 cylinders, 96cm bore, 250cm stroke = 18,000l. Most it ever makes in service is about 50MW at 96rpm. Each stroke has about 150ml of fuel injected, and we burn at most 220 tonnes a day. Refilling the sump takes about 60,000l of oil.

The Titanic engine would have been a good one to see, would have been mahoosive!!! What size ship is that for the clueless ones?!! lol

 

[Andrew]

It's from a large containership, about the same length as the Titanic, but much bigger in every other dimension (over twice as heavy in real terms). We could have whipped it's ass in a race though, and with 5% of the engineering crew. The Titanic had about 35MW of power, but it was all steam, so it needed loads of furnaces and boilers, so would have been a fair bit bigger in the engine room department.

my mate works on one of the air craft carriers and they have 4 engines the size of houses and a 5th one suspended in the air which gets swaped for maintenance :S

There isn't a single Royal Navy ship that could beat us in a race over 7000 nautical miles....
