In this video, we investigate why some areas around the world are instructing large seagoing vessels to disable power limitation systems to navigate safely.

Cars: go too slow and you cannoy people
Ships: go too slow and you will have severe control issues
Airplanes: go too slow and you will literally fall out of the sky

One engineering principle that I really wish that people would demand more of any automatic system is some form of complete override. When your product is going to be in use 20+ years eventually you will find more than one moment where the end user needs full unfettered control of the product without the normal restrictions imposed by automatic systems.

Seems to me like ships need a “sport” mode like a modern car, where power & responsiveness are improved where conditions warrant it.

Just want to let you know that next to this video I saw a recommendation for a James May video and I thought it was somewhat funny

[busslayer]

This reminds me of how traction control kicks in on your car when you might be trying to steer with the throttle or are trail braking. Suddenly you are out of position.

It is strange... I will probably never pilot anything larger than a canoe but I keep watching these videos because they are so interesting. Great job keeping them short, on topic, and super interesting!

Im serving on board a ship today

The coffee machine joke wa s spot on

[thomasmontoya]

It's a sail-by-wire system! Neat.

[KityKatKiller]

How is there not a simple "pilot off switch" for this? It seems kinda simple...

On another note: Sentences like "on the ships I served" make these videos truly what they are! I honestly don't care for big ships in the slightest. But it's actually really rare to have someone on YouTube talking about shit they've actually been taught. And it's a nice experience to find such a channel. Thank you!

Reminds me of the way cars behave now, I’m glad there’s still a place for the skill of a captain in shipping

[MervynPartin]

I have been up the Houston Ship Canal on a LPG carrier several times, usually to New Warren gas terminal, Houston. These passages seemed quite fast.
On one occasion, the 2nd. Officer told us that the Pilot was on the VHF to ask a vessel coming downstream what they were carrying. The reply was "Biscuits", whereupon our Pilot told them to get out of our way, because "Butane and Biscuits don't mix".
This was many years ago, and I didn't see the other vessel concerned as I was on Engine Room watch at the time, but I was amused to hear about it.
As an aside, regarding slow speed and electricity generation, on several of our vessels the exhaust gas boiler could supply enough steam at full speed to run a turbo-alternator sufficient for the entire electrical needs. At slow speed, due to insufficient steam production a diesel alternator had to be run too. This was, of course, before the systems that you described were in use.

Seems like if it cannot be turned off that the pilot should order up a couple of tugs. Once the company gets the tug bill they’ll get their system modified.

01:00 Your talking like there are tons of Ocean Liners. Only one comes to my mind actually 😂

[BlueTeam-John-Fred-Linda-Kelly]

Can you do a video on how the navy and coast guard conduct search and rescue post tsunami? Specifically the Japanese ones since they probably have more experience. Where big ships are allowed, search patterns for medium boats, zodiac/rihb usage, shipping/supply management, that kind of stuff.

[daveash]

Makes me wonder if that ship that blocked the Suez canal might have been under economy mode...

[chettiarsirusraj]

Well adding a ship mode led indicator to the captain's console panel along with a basic Norma:- (Slow open ocean Fuel-efficient mode), Performance-(High-speed good Fuel-efficiency), and high-Performance mode:-(All speed & Power with low Fuel-efficiency).
All the Different modes can also Add or remove all fuel consumption limits set by power regulator units according to what engine mode is set to additionally having some Variable speed controls work in parallel with each Engine mode it is set to.

[bosstowndynamics]

This kind of reminds me of the increasing sophistication in software control of cars including throttle maps - there are aftermarket remap tools you can use to dynamically chance the accelerator response curve for efficiency or faster responsiveness, but there's also the more recent introduction of drive modes in newer vesicles that does all of that with more explicit and integrated control that the vehicle is designed to work with. Are more modern ships being designed with native control over power delivery in a similar way (ie the tiller itself does things like acceleration smoothing and control remapping to optimise for efficiency, but with explicit exposed controls that could be engaged to indicate an emergency manoeuvre either as a separate "drive mode" control or maybe by having an extended range on the control inputs with an immediate response guaranteed at the extreme ends of that range).

[LegoWormNoah]

One way I can see this problem being solved (especially with no override systems) is that the Power Limiter has GPS coordinates of every channel, and automatically disable when around 5 nautical miles from the entrance. Reactivate 5 nautical miles away

Crash Stop Manuever is the ultimate ship’s engineering test. Look up the Paul R Tregurtha’s CSM footage. that +1000 ft long beast is shaking hard!!
