I am talking for myself, but I am sure everybody will be greatly interrested to see your facility.
That will be great.

This is what I call a ENGINE ! A perfect choice.
Why? Hmm, they deliver the complete propulsion incl. CPP and, can you imagine, they measure the power at the prop

So you get 600hp when you pay 600......

Looks like the transmission runs in engine oil and is not separate.

More suitable for a maned engine room.

I am not very knoweldgeble in engine, but it doesn't seams to be an ABC DX, is this a Grenaa? Is the oil pan separated or underneath and I can't see it?

Yes Daniel,
the 6F24TK Grenaa Diesel 81,5Ltr. displ. 660hp at 500rpm, dry sump.

this is a more "modern" version the 6LS24 95Ltr. 680Hp at 500rpm

I wait for the quotation.

Sweet! Quite a nice engine.
Dry sump means can be mounted slightly lower on bed, less danger of starvation of oil in the engine, and better filtration of the oil, and better access to the oil pumps. And the beauty is they offers the whole package, a big headeach less to find parts from different manufacturers.
I find Googleling this old plate taken from a danish mineweeper.

Nice plate, same engine but just half of the cyl.s.
I have received the quotation.

Ähemm, ähh, ja.
Let me say it so: they offer a outstanding good quality................................


















at 550.000 US$

Well considering the whole, the price is not that high. Just the CPP on that range of power cost a hefty amount with the shaft perhaps in the $150,000 range, then the tranny if needed, but I am not sure you need any reduction, so the engine will be around $350,000. The air tanks, compressors starter, oil tank with oil pumps, filters will be around $50,000
So the total of $550,000 is not bad.
wild guess of course.
But considering the 88 liters engine it is only $6,550 per liters which is the price of the Yanmer 9hp 1 liter
This is of course a far fetch comparaison, just for the sake of it!
Honnestly for a let say 3 millions Euros ($4.500,000) vessel, this engine complete with shafting system will represente 12% of the whole ship, not that bad.
In the long run (a normal highspeed diesel small displacement high power marine diesel engine need to be replaced after 5000 hours) this engine being certainly raited 8000 hours per year of utilisation, will save a bundle of money.
It's hard to send a check of this value, but looking at the big picture I see it as a very good deal.
Cheers
Daniel

Yes Daniel, you are right, due to the fact that everything is much bigger than usual, of course it comes at higher prices. A gearbox that size has about two tonnes and comes for 50.000€, a Al Bronce prop this size is about the same. At 500rpm I do´nt need a transmission, you see that right.
And as I mentioned in a former post, when I calculate the cost over 20 years of operation it will be quite cheap. The TBO is 20.000 hrs! Thats 4 times the lifespan of the high revving "modern" Diesels. And quite often the first overhaul is not much more than new piston rings and some new bearings on these Monsters.
The engine offered is btw. 81,5 Liter displacement and 8.500kN torque, I calculated the cyl. displ. wrong.
The airstart vessels are not included, but thats not the world. Two tanks 75ltr at 30 bar and a compressor. The additional hassle with the inspection of the tanks / bottles every second year hurts more.
But what are we doing here?
We are building a ship around the engine.................................
Sometimes madness has a nice face, I still love it.

What country you'll register? There's quite big differences in pressure vessel regs btw different countries. On the other hand it's allmost as easy to have a few days course and to become an instructor.
Inspector of course

Have not choosen the flag state yet, but British overseas Territories are usually not a bad choice (like Cayman).
The idea to make a license is worth to be thought about thanks. I have a boiler operator and inspection license (a pressure vessel too) but do´nt know if its still valid and if it covers this situation. We´ll see.

wow this was my 2000th post.......

If you're going to go "all up" for the main engines and structure (rightly so), is it worth going for a 'lesser' Flag state?

Not talkin on Richards behalf, but some countries have ridiculous regs of some inspections. Not a problem if staying in homeport but being away occasionally sailing another ocean..

ah..what i mean is...a 'lesser' Flag state may not give the level and quality one would like, i.e. is it really worth the hassle just to save a few pennies....after paying so much for propulsion and structure etc..why go for a 'cheaper' (lesser) Flag state, is what I mean.
