😂😂😂. Understood, Lima Charly. Thank you for watching Steve. CUOTO
I still marvel how you guide and control your tug and barge. Looks like a ton of learning went into your trade. Havagudun Cap.
Thank you for watching Ed. Time is a great educator. CUOTO
At the front end of an oil refinery, there are 3 distillation columns to split the crude into all of the oil weights. The first still is the "atmospheric" still, named that because it runs around atmospheric pressure. It is where all of the components for gasoline, jet fuel, diesel and so on. Out the top comes stuff that is a gas at room temperature and that goes to a "topping" or "pressure" still where propane, butane and so on separate. Out the bottom of the atmospheric still are the bottoms that go to a "vacuum" still. This column runs at low pressure to get the heavy oils to boil. Most of the heavy oils end up going to cracking to make gasoline, diesel and jet fuel.
Out of the bottom of the vacuum still is where the "bunker", "residue" or #6 oil comes from. It can't boil, even under a vacuum because to heat it any hotter makes the oil break down. #6 is really dirty because all of the junk that can't boil ends up there. That includes microscopic dirt and minerals, and the oil guys call it "ash" because that's what it produces when #6 is burned. Because of that, #6 can't be cracked by the same process used for the other heavy oils as the ash would go into the lighter oils and screw up the engine or turbine it was used in. #6 has two uses, either as boiler fuel or coking. With coking, the #6 is decomposed in a closed chamber. The end result is lighter oils coming off and a results lump of dirty carbon left over.
Not only is #6 dirty, it also can't be desulferized. That means any boiler with pollution limits has to add scrubbers or change over to #2. That's why so many places have gone to #2 oil instead, as #2 can be cleaned up. Turbines can't burn #6 because of the ash melts at the high temperatures in the combustion chamber and the turbine blades get coated in glass as the ash turns back solid. Turbines can burn #4 with the right nozzles, but #4 also has the same sulfur problems so many places have just started using only #2.
Thank you very much for watching and for the in-depth explanation. I really appreciate that. CUOTO
Always great to watch Tim and the crew in action!
Thank you for watching Dr Sal! CUOTO
Thanks for another informative video, Tim. You can never add too much detail when it comes to discussing propulsion, maneuvers, and factoring in all the many factors of weight, momentum, tide, wind, assist, etc involved in positioning the barge. Thanks for all of that.
Dave G
Thank you very much for watching and supporting the channels Dave. CUOTO
As always very informative, folks that don’t understand the port and starboard versus right, and left should check out the movie Captain Phillips when the captain of the Navy ship tells his crew to turn he says right rudder full. 😎
Thank you for watching Jeffrey. CUOTO
Excellent lesson on use of the predictor line when docking! Gliding in flat and square sure looks to be more art than mechanical power......nicely done Cap.
Thank you very much for watching and for the kind words. CUOTO
Good job cap.
Thank you Walter! CUOTO
Thanks Tim. Enjoyed it as always.
Thank you very much for watching. CUOTO
Very interesting and informative, learned alot, and enjoyed the ride, thanks captain!
Thank you for watching Terry. CUOTO
Always a pleasure seeing you doing what you do best! I need to visit PR. Thanks Tim👍🏻👍🏻👍🏻
Yes you do Milan. Thank you for watching. CUOTO
Wow I am so glad I found you, I have been binge watching your videos, thank you for making them and sharing. I love the fishing ones as much as the tug boat ones. Keep up the awesome job. I never new what was involved with tugboating.
Thank you for watching and welcome to the channel. CUOTO
Thank you again, youb are doing a great job
Thank you very much Robert. CUOTO
Like butta... thank you for taking us along! Be safe!
Thank you very much for watching! CUOTO
Love these videos Tim when your doing dock work
Thank you very much Colin. CUOTO
You are exactly right. The boilers at the plant I used to work at started on #2 and ran on #6.
Thank you very much for watching and welcome to the channel. CUOTO
excellent video nice views and informative talk thank you tim
Thank you very much for watching James. CUOTO
your welcome tim
thanks tim,good vid.
Thank you for watching David. CUOTO
Really enjoy your videos. My Dad worked back in the 50s and 60s at Standard Oil Bayway refinery. Growing up we kept a boat at Great Kills and Highlands on Raritan Bay. The loop around Staten Island with all the derelict hulls is fascinating. More recently, we have done parts of the Erie Canal on a 42'x12' barge and then the Shannon-Erne Waterway in Ireland; that barge was 49'x10'; both with Yanmar engines. The best docking advice I ever got was "Slow is your friend." Keep up the good work!
Thank you for watching John. I stopped in the highlands with my sailboat this year after going by for years. It was very nice. CUOTO
Hi Tim, I love it when I find something left behind by others that's very useful. I acquired some old charts of the Thames estuary and the east coast of UK, it had routes marked up for old flat bottomed sailing barges, with lots of short cuts that were not buoyed, On a full tide I tried a few of them and noted up to date depths and they were not far off the old chart depths, lots of time gained by not staying near the shipping channels.
Oh wow. Very cool! Thank you for watching. CUOTO
You make handling your tug look easy, You should open your own school when you retire, God Bless you and crew.
I really appreciate your kind words. Thank you very much. CUOTO
Tim, I'm an old Canadian Great Lakes sailor and all our helm commands were Port and Starboard. I have had the opportunity to take a trip on an American laker and they used Left and Right exclusively. Love your videos!
Thank you very much for watching. CUOTO
Thank you Tim for this video. I loved it... We use left and right rudder commands in the Navy as well... when you're doing detail work you don't give steady on course orders you just control the rudder directly by giving rudder orders. most people don't understand how much momentum a ship has and I am most afraid if pier is still moving past the ship at 0.5 knots... we just put one tug on the bow to control the swing of the bow, we use our own engines to control stern movement... How long do you have to wait to transfer the 2 million gallons to the powerplant? On a 50,000 ton amphibious assault ship (LHA/LHD) coming out of the ship yards empty and no fuel, we go out to sea to refuel - Navy avoids refueling in port unless there is no other option - it took us 14 hours alongside a tanker to refuel 1.4 million gallons of DFM / JP-5 - using 4 STREAM connectors. 1 million gallons of DFM for the ship, and 400k JP-5 for the aircraft (helos and Harriers), landing craft (displacement LCUs, and hovercraft LCACs), rolling stock (vehicles, trucks, and LAV-25s) and tracked vehicles (AAVs and M1A1 tanks). Once we're topped off subsequent fuelings don't take as long because we're not fueling from empty - we're always alongside a tanker looking for more JP5 for those thirsty planes... not so much for the ship unless we just did an ocean crossing - like across the Pacific.
Thank you for watching and welcome to the channel. We can usually pump off over 2 million gallons in about 13 hours. In that port and Arecibo, movements are restricted to daylight only, so we leave the next morning. Thank you for your service. CUOTO
@agentjayz fixes the gas turbine generators that you were talking about. He also fixes jet engines as a bonus.
Whatever view you choose is better than no view! Thanks for sharing your experience!
Thank you very much for watching. CUOTO
Nice weather. Grandson and I like to watch "Growler Jams" together.
He's great, isn't he? Thank you for watching Jack. CUOTO
Beautiful morning for a move Tim! CUOTO
Thank you very much for watching. CUOTO
START WITH THE CHART: Well done. Even though I'm 70yo, I too have been Google Mapping my way through to world for a decade or so. Placing landmarks in a relationship before we're moving helps the audience understand what we see from your doghouse.
Recent Sailboat Owner Suspects He May Be Living Beyond Means; Seeks Additional Income .INCONCEIVABLE!!! 🤣[cue Inigo Montoya GIF]
😂😂😂😂😂 💯!!! Thank you for watching. CUOTO
You make it so interesting cheers Tim, you asked about camera angles so I would say if it was possible move it more to the left next time to avoid the wooden panel.
😂😂😂😂 Agreed 💯 percent! I don't end up seeing what I shoot until quite some time after I'm finished with the job. Thank you very much for watching Mike. CUOTO
One Flash and your ash!!! No one knows the day to day danger. Thanks Tim
Thank you for watching
Let's hope we never find out. CUOTO
Great video Tim. CUOTO, Ed
Thank you very much for watching and supporting the channels Ed. CUOTO
Great video Capt. Tim. When you get the camera adjusted so that we can see the controls as you adjust them. What would be really neat would be a ballcap cam that can see where you are looking while you describe it. The controls, chart plotter,barge and assist tug etc... your description is great , if we could match it to a video it would be like piloting a simulator. Enjoyed the video. CUOTO
Thank you for watching David. I did a few POV videos when I first started, but everyone complained it made them sick (too much movement). CUOTO
Great camera angle.
😂😂😂 Thank you very much for watching Ken. CUOTO
30:45 ish... suggestion for a signature move: "I love it when a plan comes together!" (not so much a move and stolen from Hannibal Smith, but it really would be a signature. ;-))
😂😂😂😂😂 Thank you very much for watching. CUOTO
Fun vid!! I enjoyed my time in PR both on and off boats… fun place, great food, and the exchange rate never changes!!😂 #CUOTO
True on all counts. Thank you for watching. CUOTO
PS exchange rate doesn't change in Ecuador either.
CUOTO! Love all the vids
Thank you for watching Lester. CUOTO
👍✅ Nice video Tim, tks Let's work on a signature move LOL!
Indeed! Thank you for watching. CUOTO
Camera views out the window are better. That's where the action is. When you have multiple cameras that's when a control view is instructive. Captain used to say don't worry about hitting the dock, your gonna, just make sure it's only a kiss. Great descriptions!! Does your mate use a rake to measure farther distances or just eyeball? Signature move ... Walk to the back of the house get a soda and come back.
😂😂 Thank you very much for watching. Luke, and all of us, just eyeball everything. CUOTO
I like the camera angle. It shows a nice view of the water and the dock a head.
Thank you for watching David. CUOTO
The Mrs and I always use port and starboard when one of us is backing our boat up to avoid any confusion.
We use a wireless intercom system with one of us on the lookout in the aft cockpit and the other at the controls, since you can't see [BEEP] from the helm.
Thank you for watching. Those things do look quite handy. Rune (my Norwegian friend) has a set and brings them when sailing with us on SVP. CUOTO
Another good video from sunny Puerto Rico. Somebody watching from the shore, say like me for instance, would have no idea of the coordinated thinking and actions involved. Thanks.
It's good to see that with all the modern chart-plotter/ GPS technology on hand there's still a simple magnetic compass in the wheelhouse. That technology won't break down.
Is "living beyond my means" code for "I own a sailboat"?
😂😂😂😂 Yes Ralph and I am in love with a beautiful Latina. 😂 😂 😂 Thank you for watching. CUOTO
Seems like everyone in the P.R. videos, except you, sounds like they're from Texas! 😉
😂😂😂 Thank you very much for watching. The chief is from VA. CUOTO
"Never approach a dock faster than you want to hit it." Sage advice.
Thank you for watching. CUOTO
If you’re a true tug boater your signature move is to scratch your butt, then immediately pick your nose. Yep, that’s it. On the camera side a view looking forward with you calling out heading and ranges. A split screen with the chart plotter would be cool as well.
😂😂😂😂 Thank you very much for watching. CUOTO
When I was given orders to the helm when I was in the US Navy. I was always given orders of right or left rudder and never port or starboard.
Yes Sir. Only in the movies do they say port and starboard for helm instructions. Thank you for watching. CUOTO
Signature Move!
The Twin Screw Ska-doo!
😂😂😂 Thank you very much for watching. CUOTO
Another great video. My only comment on camera angles is the one you already made yourself in your text comment you added. #CUOTO
Thank you for watching and reading the comments Stephen. CUOTO
Learning about left/right vs port/starboard is interesting!
CUOTO
😂😂😂😂 Thank you very much for watching. Some viewers from overseas have written in the comments that their Navy's steering commands are given in port and starboard as opposed to the the US Navy only using right and left. CUOTO
Pretty sure they're called Chicksans not Chickstands.
From the brand name Chicksan that make the articulated joints on the piping.
👍
I believe you are correct!!! Thank you. I do keep forgetting that. CUOTO
Great job as always Capt
Is that Dalton in the crow nest ?😂😂😂😂😂😂😂😂😂😂
😂😂😂😂😂 Thank you very much for watching. CUOTO
Bleed that speed off! You don't want to be Mythbusters testing the adage "What happens when an unstoppable force meets an immovable object."!
😂😂😂😂 True! Thank you for watching George. CUOTO
thanks for another great video, having watched some of your other videos ( especially NY harbor for the memories) and was going to ask about your stating your speed, do you use this information or is it for the benefit of those watching. This video answered the question when you are showing and talking vectors. I never had that info, our first chart nav got it's input from Loran C- making it bordering on useless. I liked the camera setup as it was showing the dock side of the operation so "I" could approach the dock using mini ranges of the dock and shore points to compare your voice to what the instruments told you as to speed ahead or astern. Always right or left, never port or starboard, some vessels I was on even had a sign forward of the helm stating so.........
Thank you very much for watching and for your kind words. CUOTO
Another informative video. Does the barge have a captain or master or only a couple of AB. Thanks
Thank you for watching Jim. Because of the need for a chain of command, companies have invented the position of Barge Captain, although there is no such real rating within the Coast Guard. CUOTO
The outflows of power plants do have unintended effects on the environment. For example, the power plants in Florida have to be careful during the winter when scheduling shutdowns. If you look from drone shots you will see all the manatees huddled around the outflows enjoying the warm water during the cold spells. This is so important that shutting down the plant is frowned upon by the regulators.
Thank you for watching Scott. Winter's don't seem to be the same down here CUOTO
Yes, the shaft of the gas turbine drives a generator, just like shaft of the petrol engine on your home generator.
A generator converts rotational energy into electricity. Gas turbines, steam turbines, wind turbines, hydro turbines or diesel engines are just different ways to turn the rotor of the generator.
Thank you for watching Peter. CUOTO
Hey Tim how’s everything going hope all is well where I used to work they burned bunker C for more BTU output the boiler had big pre-heaters before the nozzle and in tank circulation heaters so there is no fuel gelling in the winter I hated cleaning these boilers in the summer a real filthy job
Yes Sir! And it smells bad too. Thank you for watching Eddie. CUOTO
@@TimBatSea Absolutely 👍
Hey Thanks Tim...you mentioned the mountains....maybe think about putting the camera so we can see the mountains too. But they were kinda far away though so I don't know so it's your choice anyway. Maybe this is training for me when i get a big 45 to 50 foot sailboat someday it will be easier for me docking.
Thank you for watching Randall. Have you seen my other channel (SV Paquita)? I have a few videos of me docking my 42 foot 30,000 pound sailboat, backing into a slip singlehanded. CUOTO
@@TimBatSea yeah when i still had my 35 foot hunter sailboat i always backed it in. Very controlable when backing soon as the boat started moving through the water. Had open stern to make boarding very easy. I got compliments almost every time. Sailed a lot single handed.
@@TimBatSea yeah i saw you do that. I watch them but you don't seem to sail much.
@@randalladdison537 😂😂😂 I don't seem to film much while sailing. 😂 True
Have you ever thought of using one of those head mounts for the camera? That way we see whatever your looking at
Thank you for watching. I have done that before, but everyone got mad at me saying it made them seasick. 😂 CUOTO
Lol.
Howdy Cap't. Off the wall question, what are the 7's on the bulkhead to the right of the wiper control a reference for/of???
Just kinda noticed them and when curious ask a question I was taught as I was growing up. Always enjoy your videos.
Thank you for watching Hank. So I'm not exactly sure what you are referring too, but I'll take a stab at it. Below the wiper control is our MMSI number and it has a few 7s in it and below that is the compass deviation table. CUOTO
I wonder if left/right steering orders is an American convention?
Every master I helmed for gave orders in degrees of rudder in port or starboard. As did I on my bridge.
Fun story. It wasn’t uncommon when creeping close inshore for me to order “Ten of Starboard”, only to have my helmsman reply, “Is that the Starboard towards the rocks or away!?” 😳😱😂
Sigh. Port, Starboard, Left or Right, nothing more valuable than a switched on wheel spinner. ❤️
Great post but I agree with others, and angle that shows outside and engine controls in same shot would be great. Probably not practical.
Thank you very much for watching. That was exactly what I was going for, (outside shot with controls in foreground) but it didn't work out. CUOTO
I really appreciate the time and effort you put into these videos, TimB. I'm currently doing some editing for a pilot friend who has had a hell of a time getting more than about seven minutes of footage at a time with his cameras, despite putting brand new, fully charged batteries in them. What are you using for equipment? And are you using a battery pack on your cameras or are you able to plug your cameras in?
Thank you for watching. I have had a number of cameras over the years. I am not blessed with an artistic nature and thus my videos have grown more in the vein of content over form. So most everything I now shoot is on a GoPro 8. No extra battery. I can get about 40 minutes of recording time on one battery. In the past (other older GoPros) I have used a USB C cable to a battery to enable longer time lapse and 360 video. Best of luck, and let us know how you make out. CUOTO
@@TimBatSea I appreciate the reply and I'll look into that camera. I love the content better than I tend to pay attention to the form anyway. Cheers
Hi Captain Tim!
What are those round shaped metal balls mounted on either side of the compass?
What is their purpose?
Your signature move in my opinion is knowing (almost always) precisely just how much and how little momentum to maintian on the barge to make it ease right into place every single time (well usually when the tide and wind aren't against you, but that's what assist tugs are for). You are a tryuly stellar pilot Captain Tim!
CUOTO
Thank you very much Melissa. You are too kind. The iron balls are to help the magnet compass deal with the magnetic fields in all the steel in the tug. They are adjustable to match your specific tug. CUOTO
More precisely, they’re called quadrantal correctors. (Generally called Lord Keven’s Balls).
They’re made of soft iron and are there to correct for the latent magnesium inherent in steel vessels. They are specific to each vessel and adjusted regularly. Ships’ magnetic field changes with time and the addition or removal of ferris items.
There’s another bar(s) that correct for ‘dip’. That’s where the earth’s magnetic lines enter the surface at an angle and pull the compass card out of balance.
Compass adjusters are skilled practitioners of this dark art.
Hope this helps.
@@DB-thats-me outstanding info! Thank you very much! CUOTO
There’s a new YT video up titled “Why do ships have balls?” that covers this subject perfectly. 👍
“Timmie is a good kid! He just seems to spend more than his mother allows.”
“He will need to work extra hard to get the things he wants.”
“New York, here I come…”! CUOTO 🇺🇸⚓️
😂😂😂😂😂 Are you reading my grade school report card? 😂 Thank you for watching Dick. CUOTO
If you're avoiding a crash "Hard starboard rudder!" just sounds like too many "syl-lal-ables" as the 3 Stooges used to say. Another smooth move, Cap. You'll get that camera angle right eventually.
Thank you for watching Bob. I'm a slow learner, but I'll get it right one day. 😂 CUOTO
Smooth landing Cap. What is the name of your tug in PR ?
Thank you for watching. So we only have one rule here and that is that we try very hard not to "directly" name tugs, companies or customers as it gets me in trouble with my employer. (But I have no doubt that you will figure it out if you keep watching). CUOTO
id like a full barge in my yard we are paying $9 .50 a imperial gallon here in Vancouver BC
Wow! That's crazy high! Thank you very much for watching. CUOTO
Those kind of cooling towers normally doesn’t give of any steam when they are in operation.
Thank you for watching Peter. CUOTO
Thanks for the great content share! Sliding in like silk. I appreciate the Coast Guard license management, I lost my ticket five years in because of paperwork! #CUOTO ~__/)__*
😲 Oh man. That's terrible. Thank you for watching. CUOTO
Are those iron compensators for the compass on the console?
Yes, you are correct. Thank you for watching. CUOTO
That's quite an art to maneuvering! Do you get to train on simulators like aircraft pilots do?
Thank you for watching and welcome to the channel Richard. Maritime pilots do train on simulators, but most of us have to just do it. CUOTO
@@TimBatSea It appears that you do it well. Thanks for the reply.
Tim - this was a great video with both tugs using their power, but camera angle was such that very little working action could be seen. Could not see any action from the assist tug or action on the barge. Better camera angle next video.
I'm on it Bruce. Thank you for watching. CUOTO
I have never heard of a predictor line, can you tell me more? What navigational software/equipment has it? I use Navionics on my phone, my boat has an older garmin unit that I will be replacing soon. It would be really nice to have a unit with that capability. Although it’s probably overkill for a sailboat.
Thank you for watching Jason. Have you seen my other channel, SV Paquita? You might like it. So Navionics should have a predictor line, although many call it a vector line. Many of us on tugs and ATBs use rosepoint. It's extremely good, and it's people are all US based. You can call their coders and they can basically write you any function you want or at least show you how to find the function you are looking for. A predictor line or vector line basically gives you your movement regardless of your heading. Note that many recreational sailors don't have a true heading sensor or gyro, so their heading line becomes a vector line fed by GPS movement data. I hope that makes sense. CUOTO
Yes! I was just reviewing the episode where you break down your electrical system. I have been completely overwhelmed with mine, and you made it so easy to understand. Thank you!
@@jasonlitton3762 Thank you Jason. That makes me very happy! CUOTO
👍👍👍👍👍
Thank you for watching. CUOTO
Sunlight bothers my eyes so I don't leave home without sunglasses. How do you operate in the Caribbean without them?
Thank you very much for watching. I have never been a sunglass guy, and I fear that my time on the water without them will have me getting cataract surgery before my time. CUOTO
I cant believe someone told you its not right or left, ya cant make this stuff up! I am guessing its a child maybe 5 or 6 years old watching Lmao
😂😂😂😂😂 Right? 😂 Thank you very much for watching. CUOTO
How do they earth you and your cargo?
Well, we are in a metal boat and it's in saltwater, so I guess we are earthed. Thank you very much for watching. CUOTO
How did the 2 million gallons get on the barge??
Thank you for watching. The barge was loaded with 50,000 barrels of fuel from a ship in a different port. CUOTO
How long does it take to unload 2 million gals of fuel?
Thank you for watching and welcome to the channel. It depends on the product, some products pump faster or are more viscous than others. But 12 to 18 hours in the general ballpark. CUOTO
I am more interested in seeing the view than the controls.
😂😂😂 Understood. Thank you for watching William. CUOTO
that's a lot of weight. Jet A is 6.7 ppg. guessing yours is heavier. must be difficult to control due to momentum.
Thank you very much for watching and welcome to the channel. CUOTO

GReat video..... I have one question,,,,,Hope I dont sound like an idiot. In Your upper house, on each side of the compass, there are two black round spheres. I cannot figure out their purpose. Please humor me when you can. What are they ??????????????????
Thank you for watching Don. They are magnetic compensators to help the compass deal with all the metal in the boat. CUOTO
And... if we could see where you're going.
😂😂😂 True. Thank you for watching.. CUOTO
Not a lot of room in your office
Thank you very much for watching and welcome to the channel. CUOTO
you are wasting almost half the pixels in the frame showing us the wood
😂😂😂 Very true. But it was either that or nothing as I don't have a monitor and didn't see the camera alignment until the job was over. I hope to not have that happen again. 😂 Thank you for watching. CUOTO
Bad camera position--WHAT'S THE POINT OF WATCHING??
😂😂😂 Thank you very much for watching. CUOTO
didn't like that view couldn't see anything.
Thank you for watching Allen. Yes. Agreed. CUOTO
