Here is my routine for getting the boat ready to leave the dock. It’s not perfect because I had to film while we were working and were on a schedule. Hope you enjoy it nonetheless! ... Subscribe for more!
Very clean, informative and (camera~)noiseless. Cheers, mate! Interesting fact about "floating" idle: English Electric had this issue with their locomotive engines, but after some research and few tests, they found out, it's actually better for cold engine to be heated in pulses, rather than trying to "blow thru" in stable revs. So, as a result, they left it as it is, which gave some of the engines a certain charm. (the following vid is a perfect demo of such effect for cold and warm idling) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--JpQivta6MQ.html P.s. 5:23 ... -Prelubed, warmed up and ready to take the load, Sir! -Copy that, initiate sequence... :P
The EE SVT & Deltic engines hunting when cold is due to the governor operating on oil pressure and flow (and their habit of coming to life one or two cylinders at a time). The governor doesn't react quickly enough when the oil is cold and thick. It gets worse with the number of hours on the governor due to the oil passages slowly clogging. A freshly rebuilt engine and governor will stop hunting fairly soon after all of the cylinders come to life, but one with a lot of hours will hunt until it's properly warmed up.
I deal a lot with deutz engines and they all hunt up a down like that from cold until they warm up. It will just suddenly stop doing it. And if the engine has high hours and worn it will bang upon start up and clatter and bang until it warms up. Quite unique as they have individual cylinder and they can blow out the firing ring. But I also seen a scania to do this. Which was a v8 r620 it would hunt and rough idle. Could drive for a hundred miles and pull in for diesel and it would still do it.
Old Detroit Diesels should settle into a nice, smooth low idle with no more than 2-3 surges. Even in super cold temps. If they do surge the rack isn't synchronized. Good info on these engines because I would assume surging is broken / out of adjustment. Neat video.
@@EthanLandshark When you make a "Good Enough Sea Repair" to make it home... There is one my Friend (That was in Navy) Taught me: Its a normal "Thumbs Up" but with the Middle Finger Extended Horizontally.... Means: "F*ck It, Good Enough, Let's Go" - He said you can SCREAM into another persons ear and they STILL can't hear you... so some sign language is needed...
This is the first time I've ever seen a engineer do morning start up without a cup of coffee. Walking around and not spill a drop. She looks right tidy.
Unfortunately our old diner style coffee maker trips our shore power breaker. So the newzie has to be running and power switched over before coffee can be made 😂
The special salute between sailors is a sign of respect and platonic endearment. We throw this same salute many times each day in the fire service, no doubt handed down from our brothers at sea.
I was a coxwain on LCM8 landing craft and later a truck mechanic for over 10 years. Watching this made me look back and remember all the good times. Now that I am retired, I miss the feeling of having a duty to perform and the comradeship of a team. Good job.
Thank you for your service and I'm glad I could incite some nostalgia! I'm still young and have lots to learn, so if you have any tips please comment on my future videos!
I have no history with boating so I have no idea why this got recommended to me, but I'm so glad it was. Really interesting to watch and follow what you're doing! Subbed and excited for upcoming videos!
That's what I love about such specialists: _checks oil_ engineer: "so the engine ran for about 231.6384 hours now" everyone: how do you know? engineer: You're telling me people can't just tell runtime by the colour of the oil? o.O
I work on an assist tug boat on the Mississippi River, we have a chief engineer who does regular maintenance to the boats but doesn’t live on board the boat since we have multiple boats in our company. As a deckhand I’m responsible for a lot of basic engine and generator maintenance. The only difference between my daily routine and yours is we have 2 mains and 2 generators that we switch every 12 hours because we are never connected to shore power. Also our engine room isn’t quite as clean lol
Shoddy lazy cheap engineering fix. As a Aprentice if I had offered that catch bottle as a solution I would quite rightly received a slap around the head, my head not the cylinder head! How times have Sadly changed it seems in the past 60 years.
Ah yes, the meeting of the engineers, making sure each other is okay by raising a finger. I'll gladly take your start-ups over mine though, ours last around 3 hours before we get off the wall. You've got a sub from me.
It's interesting to see how much work is involved in getting things running at that scale. Definitely not as simple as sticking the key into the ignition and starting it up!
@@markj2093 If you think this is bad, you should watch a video getting an aeroplane ready to fly ! If only it was a selector switch with options: Off, On, Taxi and Fly !

@@markj2093 Where I work it's just selecting the proper engine check that the preheater has been running and clicking "connect" then it blows, starts, revs and connects to the busboard
That engine running at idle is refer to as hunting. Have you had a governor tech come out and try to adjust them looks like you have Woodward EPG actuator could be wrong on it. Usually a small ajustment is needed. Sometimes might need to move the linkage just saying engine room is clean. You might have had a service tech come out already.
No wonder my newby electical engineering intern was cussed out. He was on a summer job where he had to pick up material in San Francisco that would eventually wind up on a remote island for experiments. He needed ships power to test his equipment so he asked the ships engineer to turn it on. He got cussed out for 10 minutes and when it all settled down, there was a moment of silence. So my friend asked "Well, can you do it?" Cussed out again for another 10 minutes and then the engineer went off in a huff and powered it up. At the bar in town that night, he ran into him and the man hugged him by the shoulder and introduced him to the rest of the crew. They were the best of buddies for the rest of the trip.
Do you have checklists or is it all memorised? In the Navy we used to have all kinds of things to prep so we had to do all kinds of Checklists. From fresh water, shore supply, checking genny's, Aux, Pumps, intakes, cooling. Etc. Nice clean engineer room - good stuff - you cannot teach pride it is innate.
All memorized! Its a sequence thats done everyday, parts of it being done multiple times per day. It becomes second nature. We have monthly and weekly maintenance checklists we go through. Everything gets logged so we know what is next.
How air tight is the engine room? I was wondering if you had a fire, could you seal off the room and activate a fire suppression system to kill the fire (let's hope that never ever happens!) then use a backup power source on the vent fan to clear the room enough for you to go in and evaluate?
Blyndem Denkilem Fairly Air tight. We have fire dampers beside the engine air intake and the smoke stack. In the event of an engine room fire it’s one of the deckhands duties to close all the dampers to smother the fire while we fight it. Most modern ships will have a CO2 or halon system.
If it was me I'd put a solenoid valve on the prelube line and a 45 second time delay relay on the pump contactor so all I had to do was push the prelube button for one pulse and not have to hold it down the whole time, or forget to open the valve. Also you change oil every 250 hrs? that motor runs 24-7 doesn't it? So that is a change every 10 days? wow.
That would certainly work for a 45 second prelube, but I don't think it's really a timed thing, it happened to take 45 seconds, but if I understand what's happening correctly what he's really looking for is the oil pressure in the engine to reach a certain pressure. I would assume it take about 45 seconds but the exact time will likely vary depending on a number of factors, such as if the engine is completely cold, or still has some residual warmth from it's last run, what the tempreture on the ship is, how many hours are on the engine and prelube pump, etc etc. As for the Oil change on the Newzi, I imagine that will run all the time the ship is away from port yes, however I get the impression this is probably a medium fishing trawler, so it may only spend 3 or 4 days at sea at a time before returning to port power. So although it's 10 days runtime, it may be a bit longer in terms of calendar time.
Really interesting!.....I sure hope you guys take the hearing protection serious. How in the heck to you communicate in that environment? If you're on a phone, I can't understand how the person on the other end would be able to hear through the noise. Stay safe and smooth sailing....
You yell really loud haha! A lot of hand signals. We can go back through the tunnel where it is a little quieter, or leave the engine and talk in the house. I wear ear muffs all the time down there.
Fascinating but at times, all of the camera movement, makes me a little dizzy. Folks never realize that ship engines are NOT push and go. That’s why you guys are REAL engineers.
I appreciate that! and thats a good note on camera movement. Ive been playing around with mounts and my solution is a giant magnet with a hose clamp that holds my phone. Worked great in testing, going to try and get two angles going on the next job :D
Yes... nice clean spotless looking engine room which "usually" symbolizes a well running and maintained engine room and components, propulsion units and their ancillary systems. Of course, we're assuming that all the fuel, lube oil, potable water and other liquid quantities are on board and staged towards their final points of utilization. And heaven forbid the duty engineer would have forgotten to off load the liquid sanitation (shit) tank prior to departure... (which I infamously managed to forget myself once). Bon voyage... au revoir and farewell. Underway is the only way!
What is the reason for running the large compressor only after switching to internal power, rather than its first big run-up happening on shore power? Does shore power just not deliver the amps?
That is correct, it will trip the shore power breaker. Plus the compressor will turn off and be extra load when we switch over power. Best to turn it on after.
It's funny, now that I think about it, generally yes! On our boat at least if there's time for middle fingers to be shot back and forth, everything is good haha!
It's when he doesn't flip you off that you have to worry. At the coal plant, if a person doesn't tell you to go f yourself, it's because you aren't friends.
The 13 was a typo. It is a KTA 19. Generally we don't run it higher than 1800rpm when travelling. High RPM is 2100 but never really get there unless were trying to avoid something. Its rated at 450-700 HP. Its small for sure but we can do 9 knots with 250,000lbs on board at about 1730 rpms! Here's more info on the specs www.cummins.com/engines/kta19
At sea, basic things like domestic plumbing, basic electrical, pumps, hydraulics. We can do a fair amount of jerry rigging to get a job done if we need to. Anything major like an engine breaking down we would need help from a mechanic. Its very situational, first we try to fix it, if we are unable we call our operations manager who has a wealth of experience, if he is unable to guide us to a fix, then we call for outside help.
Great video! 0:53 Now why don't they have a button like this on cars? I guess this means when you start your car, the first few turns of the crankshaft there's no oil pressure and it wears out the bearings faster than it needs to :-(
You mentioned the oil being dark. Having driven diesel trucks, farm and construction equipment my experience is that the oil is pretty darn dark in just a few hours after an oil/filter change. You seem to have a different experience. Am I reading you right on that?
I agree, that tends to be from oil that has settled in the engine and lines mixing with new oil after things circulate. I still find that you can get idea of how old the oil is based on the color and cloudiness. I have an oil change video coming soon! Hit the subscribe button so you dont miss it!
At the time of filming, we were only shut down for a few hours each night because of our schedule. After offload around 3-4am everything is shut down and transferred to shore power. Then around 5-6am depending on where were going, were starting everything back up again. All crew slept on the boat so we left things that could be left open for like fuel lines and water intakes. electrical is still on so all alarms are active as well. For fuel there are two main valves for port/strb tanks, then a fuel manifold for returns. In operation we monitor fuel levels with a sight glass and switch sides every 4000L or so, keeping the difference around 2000L. Fuel capacity is 8500L/side. As for water there isn't much for the engines as they are keel cooled. The only main water intakes we have are for the fish pump, which remains off until were ready to prime, and the water intakes for the condensers on our refrigerated seawater system. Those go on right after leaving the harbor in clean water. edit: typo
Why does what is a 6 cylinder Diesel truck engine running a Genny need a pre lube with a electric oil pump. It did not in the truck or as a shore based Genny. Is the temperature super low in the engine room, or has the Genny never run for many years? In the past Very large Aeroengines needed a pre lube from a electric oil pump if left overnight. But that was before an during WW2. Just asking.
@Bored Guy You 100% know waaay more than me when it comes to engines. If the main engine is under 1000HP you don't need a license to engineer on it. My job is mostly pushing buttons, turning valves and changing oil.
There is a transmission in between, but yes. If you pause at 3:15 you can see the transmission. It’s the beige rectangular thing on the back of the engine, right behind my hand, play the video and you get a quick look at it. Most of it is under the floor plates. The propellor shaft is directly under the floor plates from the back of the engine, all the way through the tunnel and out the stern. While in transit you can see it spinning if you lift the floor plates.
You Have A New Message The main is larger, the lower half of the engine and the oil pan are below the floor plates. It’s why the dip stick is so long 😂 The main is also lower pitched and in the video only idling. The newzi runs at a pretty consistant high idle to maintain power. It’s just in the morning when it’s warming up, doing that slow rev, while it’s the only thing running. When we leave the dock you can hear every rpm change of the main. It’s a nice low hum, great at bedtime
wheelChaircripple If there is an oil leak it would drain into the bilge, we would pump it into buckets and dispose of it at a fuel facility. Bilges are checked daily. Oil levels are checked every time the engines are started.
wheelChaircripple There is enough room in the bilge that all our engines could dump all there oil a few times before it would set off the bilge alarm. That would never happen, we would detect a leak well before that haha
Geoff Mcgowan that gen/hydraulic pump is almost as big as the main lol. I thought the main was going to be an EMD or MAK. It might be a medium sized trawler or something.
It was a medium sized trawler. It has since been converted for another use. Packs 295,000 pounds of product and chills to 1 degree C using a Refrigerated Sea Water system. I'd prefer to leave the fish aspect off of the channel and focus more on the engine room, vessel operations and crew. Hope that wasn't TOO vague :)
I dont know what that means so I am going to say no. There is a sequence of breakers to flip but for a brief second between turning the main breakers on and off the ship is on emergency power. Which is why the lights go out.
The engine will start unlubricated, so there will be excess wear and tear on the engine. Forgetting to close the prelube valve just means that oil can flow through the oil pump. That wont hurt anything short term but long term (like doing that everyday for a month) would wear down the pump. :)
There isn't a decompression lever on that engine (the Newzie). At 00:59 the button my pushing is the pre lube for building up oil pressure in the engine. a few seconds after I point out the gauge I'm looking at. Once oil pressure is up its just an easy electric push start. The main apparently does have one but I've been taught to use it.
At 0:47 I attempt to pre-lube but realize I hadn't opened the pre-lube valve. It then gets opened. After the engine is running I close the valve. At 2:41 while starting the main I make the joke "Remember to open the pre-lube valve" Haha. Hope this cleared things up :D
knightrider1545 also, the switch I flip when the oil reaches temperature switches the engine to ‘high idle’, which holds the engine at the proper RPM to run our generator.
