A couple of photos for the engine guys.

Twin Pack 2005 version. 2 MAN medium speed 4 strokes (about 7000 hp each) turning alternators as part of a twin screw diesel electric plant.

Nice!:shock: And, not even an engine box to trip over.

So, if I put one of these in my 36' DE, think I could cruise around 50 kts or so? Might have to raise the sheer some...

Those things are cute. We had a single 16,500hp inline 6.

Hey Capt Larry
What wheel would you for these?

Let me do some math. I need the reduction gear of the tranny.

Does it have a trolling valve ?

 

[Raider Ronnie]

How many gallons a minute it burn ?

Nice looking engine room, what kind of ship is it on. Those engines have great access to work on, the MANs i was working on where hoooorrible to work on. I do miss the old slow speed 2 strokes, those were the best. 7 cylinder, twin turbo, 14,000hp, turning 138 RPMS at full sea speed!

190,000 ton NASSCO SuezMax operated by ATC. I took these pictures on the ALASKAN EXPLORER. 2 engine rooms with this package in each. 4 engines into 2 variable speed electric shafts. 20 MW total.
600 bbls/day (25,000 gallons) IFO 380 @ 15 knots. This is off track for the forum but I figured we all like a clean engine room.....

Thanks for sharing Duke.

Nassco has been building that very similar plant in manyof thier new builds, it is a proven winner.

What purifiers are those? Don't look like Alpa laval. And to be that clean on 380 must have been a pic taken when it was very new......

What is the bore of the engine? Were there aux generators also or did you run 1 MAN in port for power?

FWE

 

[Duke]

The engines are MAN B&W 6L48/60, 6.3MW. 480 mm bore, 600 mm stroke. No aux generators, the MAN's come on and off line as the load dictates. Normal idle load in port is one engine at about 15%. Sea speed all four at about 80%.
I think they are Alfa purifiers. It has been awhile since I was on there. As clean as they ever will be, the photos were taken on the sea trials. The electric side of this plant is a whole 'nuther discussion.

Okayk, show & tell. In the words of Hooper in JAWS (during the drinking scene) "I got that beat...". GE 7FA+e gas turbine (175 Megawatts) burning #2 distillate - a LOT of it. I've often wondered why no one has tried to put a gas turbine in a DE yet. With only one moving part, should be pretty reliable - and sound really cool...



Hard coupled to one of these:



Love the diesel engine room pics! Thanks for posting them; looks 'ship shape'.

 

[CEShawn]

Who is the guy in the purifier picture? Meba crew right?

 

[WoundUpMarine]

Cool looking turbine, ill try and scrounge up some pictures of the old girls i've been on.

 

[WoundUpMarine]

This isn't my ship but we had the same engine, only a 7 cylinder version. The moving plate is the very top of the exhaust valve assembly. The valves are opened hydraulically from a piston actuated off the cam shaft and then are closed by the force of the 6 springs on top. It was a cool old 2-stroke engine, but the whole ship is razor blades now.

Duke,

25,000 gallons/day ??
How big are the fuel tanks on this "boat" ??

 

[Duke]

The total fuel capacity was about 25,000 bbls, which is relatively small for a tanker this size.

 

[WoundUpMarine]

The rig i was just on carried a total of 5613 m3 or 1,425,702 gallons of marine gas oil (#2 diesel oil). We burned between 40-60 m3 a day depending on operations(10160-15240 gallons). that's a LOT of money to fuel up!!

 

[captainlarry84]

On those boats do they put the little nut on the propeller first or the big one?
