RORO Ship: Driving a car across the ocean | Hacker Day

YouTube has done a great job of making itself a target of criticism, but you can say one thing to their algorithm: when they work, they really work. For example, I found a suggestion for the latest video about salvaging a sunken ship in my feed the other day. I can't start to guess what combination of viewing history and metadata Google has dug to come to a conclusion that I am interested in this video, but they hit the nail on the head.

But more importantly, their algorithmic evaluation of my interest must be a gold mine for them — or if I don’t have a minefield protecting my ad blocker, it may be a gold mine — because I fell into A rabbit hole caused me to fall into a bunch of interesting videos. It turns out that the shipwreck in the first video was a cargo ship carrying thousands of brand-new cars, all of which were destroyed in the fire and subsequent "roll-on/roll-off" (RORO) capsizing in Georgia in 2019 (State, not country) ships near the coast.

Therefore, I embarked on a ro-ro ship tour through which cars and other bulky goods are shipped to all parts of the world. Although my personal assessment of Hackaday's reader interest may not be as refined as Google's algorithm, I think people may also like to follow posts.

Entering the first video without any background is a bit rough, because it was mainly a drone shot of the rusty part of the MV Golden Ray sitting on a dry dock barge. There are hundreds of cars in the area, and a very skilled grab operator is now pulling out the rusty wreckage. The seven parts that this ship was cut into during the salvage process are amazing in scale, so I naturally looked up at the golden light to see what this huge ship looked like, at least better. Days.

RORO boats are designed to carry anything that can be driven on their own or with the help of some kind of tug or tractor. Many passenger ferries fall into this category, but the behemoths of moving cars and trucks are the stars of this category. The largest ro-ro ship, MV Tønsberg, is 265 meters long with a beam of 32.27 meters and can carry 41,000 tons of cargo. According to the mix of goods, there are approximately 8,000 cars.

Like most cargo ships, ROROs are well suited for the type of cargo they carry, and because they are designed to allow vehicles to drive on and off them, they look very much like floating parking lots. They are very unattractive ships, square and angular, but unlike the same awkward container ship brothers, RORO stores all cargo under deck. RORO is designed to be moored next to the pier, which produces their most distinctive feature-the stern ramp. The ramp was built on the sloping part of the stern, not just the gangway. It is actually a folding two-lane highway entrance ramp, about 12 meters wide, capable of carrying hundreds of tons of cargo. The lower part of the ramp is also used as a watertight door when stowed, so it is a very complex and important device.

Once the ramp is opened, cargo operations can begin. RORO usually calls at multiple ports during the voyage, so the cargo is usually loaded and unloaded at the same time. This leads to an absolutely fascinating ballet, because sometimes hundreds or thousands of cars are dragged away. The logistics involved is unbelievable-care must be taken when loading cars so that they are not obstructed by cargo scheduled for later ports of call, as this can lead to a resource-intensive process of "transfer", time, and temporary removal of vehicles .

The amount of labor required to load and unload RORO is staggering. Every vehicle must be boarded or disembarked, so the more drivers, the faster. Everything needs to be carefully choreographed so that the car is constantly in motion and there are no accidents. Drivers usually work in squads; each squad is equipped with a large bus that can quickly send them back or disembark after they have unloaded or loaded the vehicle. This maximizes the amount of cargo that each driver can handle in a shift.

Although the main task of most RORO operators is to transport new passenger cars and trucks, this is far from the only cargo they carry. Many ROROs are able to adjust various parts of their decks and ramps to accommodate "high and heavy" cargo. This can cover everything from tractors to buses to heavy construction equipment or anything that can be turned through the stern door.

No matter what the object is rolling on the ro-ro roller, it must be fixed before the start of the voyage. The RORO deck has cutouts for lashing straps, and there are strict specifications for lashing each car. During the voyage, the crew must go up to the deck every three days and inspect each lashing strap to tighten any straps that are slack due to vibration. Given that there is usually only a few centimeters of space between cars, this requires a certain degree of flexibility.

If you have free time, I will find below a documentary detailing RORO operations-as a bonus, check out the complicated process of the Panama Canal passage. It is always satisfying to learn a little more about how the world's supply chain works and how it doesn't work.

In these matters, it is very important to close the door before sailing. Is it still called nautical?

There is (or at least once) a ferry service between Ludington and Manitowoc that crosses Lake Michigan. The ferry is a behemoth of steam-powered icebreakers whose initial job is to transport rail cars full of coal in any weather. Lake.

This is an interesting ride. Although it is "only" 125 meters long, riding it will give you an idea of ​​the absurd size of this boat, because it is a "small" boat.

SS Badger, it still runs according to Wikipedia.

I used to watch Vikings, Badgers and Milwaukee from the 1970s to the 1980s (hope I remember correctly!) Ferries departed and arrived in Frankfurt, Michigan. It is always a miracle to see such a large ship sail into the port and then swing the bow nearly 180 degrees to align with the dock. They usually mix passenger cars and rail cars. No matter where you are in the city, the ship’s horn will tell you that it has just docked.

There are many operating points between the UK and the European continent, so this was the main way my family used to vacation when they were young. Drive the car (and caravan) to Portsmouth, board the ferry, and then drive to France in 5-6 hours.

I took a bus from Germany to London in the 1980s. We took the ferry (after visiting Amsterdam) across the strait and spent the night in a cabin. We returned to Brussels. The overall travel is pretty cool.

So when RORO has a problem, Scooby Doo will say "Ru-Roh!"

RORO your ship... now I'm leaving, on the left side of the stage.

I want to know if these ROROs are LIFO or FIFO?

A few years ago, one of the cars was in the port and for some reason was opened to the public. It is like a large and empty parking lot.

Clive Cusler introduced a robot ship in one of his books. The result was not so good.

"...When they work, they really work." For more than ten years, I have been using YouTube every day. It has never, even once, suggested to me what I really want to watch. Obviously, this is an insulting profit motive. Over the years, I have spent dozens of hours dealing with their "suggestion" user interface and other irrelevant marketing nonsense, just so that I don’t have to think that I’m in a used car park and there is a stressed salesman trying to chat with me Every 3 minutes.

It also works badly.

Oh? Did you just watch and comment on the 90-minute video? The video is about reverse engineering, memory forensics, and kernel debugging?

But it uses video games as a partial example. So in the next 4 months, I will use PewDiePie, Markiplier or some 13-year-old kids to scream on Minecraft to fill in your suggestion feed. enjoy.

They never recommend any content that is similar to the content I watch frequently, because most of it has been demonetized. On the contrary, the most important recommendations are the same for about a year or more. Event though I never chose it!

They used the most brain-dead AI I have ever encountered :)

It is not artificial intelligence, nor is it trying to recommend things you like. This is a set of filters, metadata, and algorithms that heuristically suggests monetized videos that you are unlikely to click on.

This is where they fail. I’m most likely to click on anything I didn’t specifically look for. My mentality resides firmly in their blind spots.

There may be a meeting where someone says, "But if people do X, Y, and Z, these won't work, and they may annoy them." Then another person may say, "No, no one does it." or " Who cares about a person?"

I do this. I am full of X, Y, and Z, and Youtube is always frustrating.

One of my favorite shipwrecks is Zenobia, a 172 m long Swedish ro-ro ship that sank on the coast of Larnaca, Cyprus during her maiden voyage. Caused by the problem of relatively modern computers operating the ballast tanks. It is often named one of the top ten shipwreck diving sites in the world. More than a hundred articulated trucks are still on board and can be admired.

I almost never use Facebook, but the other day I was checking some content and deciding to click on the news feed (if this is the correct term), I am interested in 100% of the articles. The only way Facebook can do it is if they get data from a Google account I have never used, it means they get content from the Google account I use or directly from my Chrome browser history.

Anyone who thinks that anything they do on the Internet is "private" in any sense is an illusion. I don't care how many VPNs, privacy settings and privacy browsers/applications you use. If "they" want your information, "they" will get it.

...Or from the cookies you are tracking you online, or just because you know what your friends like.

Use Firefox instead of Chrome. Chrome's private data is very leaked. In addition, if you have not used uBlock Origin. Prevent the development of sh$t.

No. Will not prevent anything. If they want it, they will get it. And don’t forget the 30 years of data you haven’t protected since you got your AOL account in 1990. Privacy is a myth. Mozilla may not track you, but your ISP will. Those sites that promise not to lie. At best you slow them down. Fish swim in the school, so they are probably not the fish that was eaten today.

Give them a bunch of fake data to get rid of them. http://makeinternetnoise.com/

You can book them to travel with your car.

I thought it would be about some ships with some kind of generator, the car can be turned with tires to provide propulsion for the ferry. Wow, my imagination is really working overtime to fill in the blanks until I finish reading what this is all about. Nothing is driving a car anywhere. This is just ordinary land and water transportation. = (The title is a bit of click bait.

There is also a Coast Guard investigation still underway

Last year, I was fortunate enough to help with the speed test of a new Roro. The statement that the lashings are checked every three days makes sense: these boats are built for speed and capacity, not for comfort, so the vibrations can be significant. Especially the airship trial, it feels like being in a shopping cart of 18 knots. One of the network switches I used in the engine compartment was indeed unaffected by the vibration, and four screws popped out!

I recently (as a pedestrian) traveled from Genoa to Sardinia and later returned to Toulon. What surprised me was:-There is a lot of empty space on these ships because there are only a few trucks on the "high" deck at the bottom. I have seen ships with movable decks so that one truck deck can be moved to two car decks (whole deck or half deck) – the skill of deckers to persuade untrained tourists to park their cars in compact packages – lots of idleness Time ships stop at the port (for example, Moby Aki spent 10 hours sailing from Genoa to Olbia, but back and forth every two days-I thought it sailed every day, possibly alternating with shorter routes (such as Genoa) -Corsica) to make it more efficient. The ship I transferred back to Ajaccio (Corsica) stopped on the way, berthed in less than 2 hours, unloaded and loaded some trucks and cars, and then loaded it again, even if it was Three-tiered car.

Earlier I took a ship from Denmark to Norway. The deck structure is not a flat deck with a ramp, but basically two intertwined spirals, so you always have to go all the way to the top, and then a total of 7.5 The circle can enter the transport and return.
