Life finally goes on.

Well at least some sort of production in my life is resuming now, despite ‘rona.

It’s the senior level of vessel system plant management (Engineering) and was axed for an entire year. Even now intake was cut 50% to 6 people.

Last course I have to take for a few years at least. It’s the one I like the most, good at, and actually real world applicable of exams. Then it’s just time and annoying flaming hoop tests.

This is the practice desktop, behind is the actual sim room.

Send it.

Hah, that’s Send It; Astern (or Reverse for land folk)

Actually done a few crash stops in my day. Both planned and otherwise.

@exage03040 What's up with the black duck and the yellow duck, each drinking a can of beer?

It’s always 5 o’clock in international waters.

[orneryduck]

@roadkilled NOS pumps, two of the big ones.

[ClassicDatsunDebate]

@exage03040 Every time you change the control lever, you should yell it out in your best Sean Connery voice.
Also, does "Critical 40-42 rpm mean those RPM's are locked out in the ECM because of the critical speed of the prop shafts? high vibration ensues?

As someone who does industrial controls including HMI design and development, I give a solid "what the fuck" to the right screen. Do they want you to go blind and also not be able to quickly identify what's going on, or do they just really like the color green? That's worse than a lot I see which are at least high-contrast, if not eye-searing.

Edit: Your pumps look like potato smiles

Where is the manifold, and is it in Danger?

@mm54 As a pump guy, I THINK they denote either gear or rotary lobe pumps but I'm not sure...haven't seen those symbols before.
What flavor do you normally work in? ControlLogix? Other than the overly expensive and proprietary A-B stuff, I'm surprised with how the HMI/PLC/VFD integration is becoming so smart and simplified now a days.

[MM54]

@classicdatsundebate I mainly meant by the color scheme, I've seen most any picture for a pump being used, those are probably lobe pumps like you mentioned.

My company does any platform you come up with (now and then a customer pulls something bizarre out of nowhere and emails start going out asking if anyone's heard of it), I personally mostly do Rockwell stuff (so controllogix/compactlogix/micrologix/SLC/PLC5/etc, FTView in its various flavors, and so on) but have done some schneider/modicon stuff, iFix, and dabbled in other random crap. These days more of my time is on the electrical design side than doing the coding and HMI development but it flops back and forth project-to-project, depending on what's needed.

Stuff integrates pretty smoothly these days for sure, the latest in-family hardware is getting close to plug-and-play with everything over ethernet, equipment config loaded from the PLC, and so on.

Why would you give your NOS to the ducks to drink?

I actually do a good Connery voice. The boys were having problems slowing the ship down so I told them they should do a “Crazy Ivan” (kudos who get that reference).

Yes critical is where the engine frequency matches the hull so if you ran the engine at that speed all the time it’d break the crankshaft.

Eh, I don’t find it that bad. System ID is easy when you’ve looked at all this screen stuff day in and out for years. Kongsberg is green, Wartsila is blue, same same to me. I deal with more complex systems with the LNG anyways.

You joke but we will have a scenario with scavenge fire.

Release the CO2 and crack the welds on the “intake manifold”

Two technical questions...

As the engine passes through the critical RPMs on it's way up or down, can you hear or feel the resonance? I did a little work once on a pump system that had a critical frequency at a reasonable engine RPM. Even passing through that speed - as fast as possible - it was very noticeable. The normal (very loud) brrrrrr briefly became a WHOMP.

Scavenge fire - yikes, external combustion is sub-optimal. Is the main cause something our old-Audi owners would understand? I.e., turbo oil leaks?

No, I’ve never felt it. All bedplate [solid] mounted so you feel vibrations at all maneuvering speeds either medium or slow speed. Nothing discernible which is why critical speeds have to be posted. Typically you just have matched speeds off of it when dead slow, slow, half, full are basically a specified rpm for both Deck and Eng.

It can be due to turbocharge seal but the sources can vary because it’s 2-stroke uni flow scavenge. Can be blow by, fuel, cylinder oil, oil and deposit accumulation. I usually work medium speed so I’m not the most familiar with it but this gives the reasons.
