- Assisting the Maersk Idaho from the lock to her berth.
My apologies for the shaky video from time to time.
For the pricavy of some co-workers i used some mosaic effects thruout the video. The mosaic disappears at 25:39
This is a 4K video instead of the FullHD i used on the other dualcam videos.
Please give a thumbs up if you like this video. Also leave a comment I you want :)

missing your tug videos ... for me as a tuggie lover... would love to see moree
amazing control of the boat. he knows his tugboat extremely well
I have so much respect for you guys operating the tugs, in Cape Town, these guys are constantly busy and i dont think people realize the skill and training required to do this job, Interestingly Cape Town only has Voith Schneider tugs! :)
Love your videos! The control cameras are awesome too! Please keep it up! Best videos around about the Voith in action!!
Great video. I watch it on full screen, with the volume up, just like being on board!
Wow amazing work at those controls.
Love this video😊 keep making these awesome videos👍🏼
I love this video, the 4k look amazing. Keep up the great filming.
We snapped a mooring line tying up to that berth, you really cant tell that she's drifting back all that much but she came back and we blew one of your after springs. The locks to the MSC home terminal was always a cool transit especially after the 7 hours or so it took us up the river to get there. Cool to see from the tugs perspective.
Weer een mooie video en prachtig om voelen als de pk's los komen dank hiervoor
Wow Amazing👍
Nice video, thank you!
Thanks allot !
Nice video thank you.
Very nice thanx
nice video. I working on VSP tug,too.
probably because the traffic is close of high, in this video you don't hesitate to push the power at 80% & 100% a lot of time for a long period of time, never seen that at this level in your videos (except for one), no worries for the shaking, the sound is a real pleasure :D
I don't want to know the price for refill the tank XD
So F'in cool! Wish I had your job.
any chance you could place a microphone outside or crack the door or a window so we can hear the engine and turbo even more :)
I have a question. I know most big ships now have bow thrusters. And the Idaho has just 1. Are they not allowed to use them where you are? Is it too shallow? Do they have too shallow a draft? Or is it simply that the turns are in too tight a space for them to try and maneuver by themselves?
👍👍👍👍👍👍
I heard an alarm go off about the 40 minute mark. I'm guessing that's a bilge pump warning? Also, do the engines tend to overheat if you hold them at max pull for a prolonged period of time? Thanks for posting! Some awesome horsepower on these tugs!
What are you blocking out on the dock right side?
Good stuff. I really enjoy your vids. Question: What determines when a tug is needed?
when it may cost less than repairing the ship and the harbour
Hi guys. Ik geloof dat ik niet op dat kleine oranje sheepje zou varen, voor je het weet ben je een vet vlek op de muur van de kade. Wel een mooi stukje werk, dit schip had een paar lieter diesel nodig om er te komen. Het was maar goed dat er niet al te veel wind stond.
Dit zijn de 'bootmannen', of ook wel 'roeiers' genoemd. Deze mensen weten waar ze mee bezig zijn en kennen hun vak zeer goed! Respect voor deze mensen want ze werken soms bij zeer slechte weersomstandigheden.
What is that big black mark on the Maersk bow near the top red line? It looks like a big hole! Guessing it’s just a smudge? Love the vids capn! Keep em coming :)
Excellent video. What camera did you use for 4K recording. Bravo.
A brief description of what the controls were doing would have been a bonus. Are the slide controls to the left throttles? What do the indicator lights next to them tell? I assume the wheel controls direction. Thanks for posting not trying to criticise just had questions
Are the propellers located on the front end or the back end of the boat? Awesome vid by the way :D
Absolutely beautiful! As with many things, it seems as though the last 5% of the trip takes 20% of the time. On a job like this, I suspect you spend most of your time watching the ship and the towline, looking, like your camera, towards the stern of the tug. If that's true, then how do you also keep an eye on what's going on ahead of the tug, in the direction of travel? Is there a forward-looking camera with a display that you can watch while facing the stern, or are you constantly turning back-and-forth? Great job, as always! -Chris
Yep, from time to time I turn my head to look forward. But when towing a big ship there will be very few ships in our path :)
ShippingHarbors your vids I love em...great work...how do u get into doing this kind of work
very nice video what is the small smoke stack used for, and what is that alarm i can hear in background. have a nice summer from Tommy in Denmark
not sure what you are refering to by the stack (asking the tug?) but that alarm towards the end is just the gantry cranes moving on the pier side
Very interesting ! don't apologize for some shaking images, you feel then the power of this tug (an external general view would have been welcomed, though, just to know the size and type).
What is the use of the small keypad with red-orange-yellow lights ? changing power setting more radically than with the throttle ?
The buttons controle the rpm of the engines ;-) You can see the tug from this video in a video that is called 'push captain push'.
+ShippingHarbors - your videos are fantastic, and really demonstrate the skill needed to operate a tug. I'm a bit confused as how the engine rpm relates to the throttle, is it because the propellers are electric drive, so therefore can operate at 100% at all engine RPM, giving a varying amount of force? Is this to conserve fuel, as opposed to operating the engines at varying throttle? Also, the engines seem to respond to the throttle command, without a change in the RPM indicator(red button lights?) (at 9:05 for example, the engine seems to rev up and then down again, with no change in the RPM indicator). just curious. Thanks for sharing.
That is all correct except it's not 'she' but 'he' ;-) Why did you think im a girl? Haha
Hahaha Okay, no problem ! Indeed, in that video it was indeed a 'she' at the steering wheel. It was my colleague that was training for captain.
kevin kuhn the "revving up and down" that you hear is actually the engine's turbochargers speeding up as the captain increases propeller pitch. When captain increases pitch, the engine has to do more work by adding more fuel (black smoke) and air (turbo noise) in order to maintain the fixed RPM that is selected on the button panel. Captain can set a higher engine RPM at any time if he needs more power than maximum pitch (when the levers are pushed to one extreme or the other) can give him. Middle position on the levers is no pitch, or neutral. The propellers will always rotate in direct relation to engine RPM.
what controls the throttle? i se the levers on the left move, but sometimes they are half way and it sound like full power?
David C engine speed is controlled by the two rows of buttons shown next to the pitch control levers. Engine load (and thus turbocharger speed) increases as propeller pitch increases.
thanks, ive done my research since then! great tugs!
Superb video again!! The camera position may be more shaky than other positions but the exhaust sound of the engines is great. ;-)
Just a question: When turning the ship just behind the lock (starting at about 27:00), you seem to be giving full throttle. Are you pulling the Maersk alone without its own engine?
I'm going to try a different spot next time, but still near the exhausts tough. Hopefully that spot is less shaky. The manoeuvre at 27min is to help the ship turn to starboard. The ship in fact is using it's own engine with rudder full to starboard to make the turn.
Thanks for your explanation! :-)

You're Welcome ;)
I am curious about the use of buttons to control engine RPM. Is this done because there are some engine speeds which should be avoided like on the larger ship engines?
+Coolkeys2009 It's not like a car which goes faster when the engine goes to higher RPM :) The speed/bollard pull of the tug can be adjusted by the propellers pitch. Sometimes the lowest rpm's are enough to pull a ship (smaller ships). Lower rpm's mean lower fuel usage. These tugs use up to 1200liter of fuel per hour at full throttle, so lowering the rpm's will also lower the fuel usage very drasticly. I hope you understand what i mean, because my english is not good enough to explain it with more detail :)
ShippingHarbors Your English is excellent. I understand what you are saying about using the minimum engine RPM needed for the force or power you need to apply. Many applications using larger diesel engines such as trains seem also apply the throttle in discrete steps instead of having a slider you can set anywhere between minimum and 100%. Just curious.
oh very interesting! i did not know the propeller pitch changes!
Thanks again for the ride along! Out of curiosity how long on average does it take to become competent operating a Voith propulsion tug? I used to drive my fathers 3400hp Z-drive occasionally and actually found it quite intuitive.
+Helidan It's like driving a car. You can operate the basics within a few weeks, but it will take allot longer to make all the controls a 'routine' operation so you don't have to think anymore what do to with the controls.
Do you spend any time in simulators?
Yes, but that was only at my training to become a captain. The real thing is much more realistic then the simulator tough.
I can quite imagine! Do you ever take the tugs offshore or do you never leave the terminal areas?
Nope, these are harbortugs :) They are not allowed on the sea.
ik neem aan dat je uit moet kijken om het trossen bootje niet tegen de kaai aan te stuwen ?
tijdens het omtrekken , gaat er niet veel stuwkracht verloren als je tegen het schip licht te stuwen in plaats van ervoorbij ?? hoeveel bollard pull heb je tot je beschikking ??
Id love to work on the sea
Where were you at? On holiday? Glad yer back.
+Robert Hale Been sick for a week, then got some bad weather with allot of rain that prevented me to install the camera outside :) But now i'm back, and hopefully a new video about every week (if the weather cooperates).
Well, looks like yer back on yer feet feeling better. Time to watch the vid.
Robert Hale
Yep i'm back :) Enjoy the video, and let me know what you think about it. And if you have any tips to make it better, or things you would like to see just tell me ;)
Will do.
I thought the slightly larger control views worked better. Was wondering why the pilots radio commands can't be heard? Are you wearing a headset? The addition of what instructions you are receiving would really top off what is already some great videos! Keep up the great work.
do these tugs have swiveling propulsion units?
David C they are Voith Schneider Propellers. Google it. :)
Why is any propulsion system other than Voith Schneider still being used?
Depends on what the tug is designed to do. Most harbor tugs designed to mainly assist ships will be either voith-schneider or Z-drive. For tugs that are designed for coastal towing over longer distances, a twin screw conventional design can be more efficient. Of course, that is just a generalization.
how the left controls work? (the buttons and levers)?
Breno Marcilio yes the same question bcz its not matching with Rpm sound 🔊
I think the throttle-like levers are controlling the pitch of the blades and the orange buttons the engine rpm.
Yeah, or the buttons are percentage of power, and the levers are requested thrust.
You should look up the info on the voith schneiders controls, the handles and the steering wheel varies direction and pitch of the VSP, orange control varies the engine RPM, thus the available power, best regards
Pulling out of lock. 50 miles an hour. Diesel`s still only idling.
+Arthur Bradley I don't get it. What do you mean
+ShippingHarbors It means very nice. Awesome power. Always good things to say.
+ShippingHarbors Did you sink?
Arthur Bradley
hahaha why do you ask that? :)
