Wärtsilä, people. Wärtsilä. I know to Finnish is difficult to pronounce, but it does bother me when a Wärtsilä employee doesn't know the name of the company he works for.
As far as I know this is a Hyundai-Sulzer 12RTA-96C (as stated on the type plate). Sulzer is a part of Wartsila of course, but the engine type still is a Sulzer, license-built by HHI in Korea.
Why do you have your "copy bug" right smack in the middle and so large as if it were a title? It would have been so nice to have SEEN the action without your paranoia in the way! Do you really think that someone would pledgerise your clip? Really!
This is actually the minimum rpm. It is doable to let it run at 18 rpm, that is the absolute minimum. But the setting for dead slow ahead/astern is 22 rpm. Maximum rpm is around 102 rpm, but at NCR, 98 is the maximum reachable - in good weather conditions.
Yes, you can see the 'overflow' of CO... However, the consumption is about 2100 kg/24h, 1.35 g/kWh which is according to the recommendation of Sulzer.. I agree that this level can be lower, and the company keeps lowering the feed rate, but then something else happens that costs a lot of money: scuffing... So better a little more CO that keeps the liner temperature down..
Plus, the lubricating system that Sulzer uses, depends on an accumulator system in the studs. I still think the timed (eg Alpha) lubrication is better.
They still examine the problem of scuffing and at some point they even removed the CO grooves in the liner! This resulted in even more ssw..

Remember the bore/stroke is 960/2500mm

Is this engine scavenged by blowers or by bleed air off the turbochargers?
douro20 4 years ago
Scavenging air provided by 4 turbochargers. In lower rpms (<65 rpm) two auxiliary blowers feed the cylinders.

The engine is a Hyundai-Sulzer (license built) 12-RTA96C, MCR of 65880 kW @ 104 rpm, 265 t/day HFO 700 cSt injection temp at abt. 148 degC.
NCR 90% MCR 59290 kW at max 96 rpm, abt. 230 t/day HFO.
No critical rpm field. Diam. 960 mm and stroke 2500 mm.
Lubricant was Shell Melina S30 I believe, but it was to be exchanged for another brand just after I signed off. Total sump filling approx 45.000 ltrs.
