- Hey everyone,
Here's a quick look at the M/V Saginaw unloading in Toledo, Ohio.
**Time Stamps Below**
I'm not sure what it's unloading, so hopefully, someone can chime in with its cargo.
We'll take several passes of the vessel and a look into the cargo holds and more.
I hope you enjoy and consider hitting the thumbs up and subscribing.
Until our next trip, have a great day!

I'll try to answer a few of your questions! During unloading operations there will usually be a particular amount of trim the chief mate wants to maintain, the mates will maintain this trim by filling ballast tanks in the same sequence that cargo is coming off the boat (for example: hold #1 is being emptied so water goes into the #1 port and starboard tanks). They will also fill or hold other tanks, at the same time, to maintain the desired trim, reduce any list from the cargo coming out unevenly, and keep the hull stress to a minimum. They start at the aft holds so they can keep the stern from getting too deep while maintaining a trim that is down by the stern. Its essentially a big balancing act. Assuming the vessel arrived at the dock with something typical like 3-4 feet of trim (down by the stern), if you were to start unloading the forward hatches the bow draft would decrease and therefore increase the stern draft. Lots of these docks only have a few feet of under keel clearance so there's a chance the stern could end up on the bottom if too much weight is discharged from the forward holds too early. Lots of this style of laker have cargo hatches that were designed specifically to load at the chute docks around Lake Superior, the ship builders at the time went with this restrictive design because many of these boats were built solely with the steel industry in mind.. the owners of the ships back then weren't building for versatility or longevity, they needed to more iron ore, they weren't thinking about what cargo they would be hauling in 2024.
Thank you very much for the great info and detailed response.
I, along with others really do appreciate it.
@@nkyrailfan no problem!
Also it's very important to keep the ship in balance by unloading evenly across all the holds, to control the bending moment in the ship. On two occasions I've been asked to investigate incidents when a ship had its back broken in the dock by loading too much in one place. Expensive mistake!
@emmetthawkes4474 I would hazard to guess the additional bracing at the top of each hold is important to the structure of the ship? I would imagine the loading/off loading methods worked within the restrictions of the engineering at the time. Big hold needing big supports, dock equipment had to work around it. I'm just spitballing. Your thoughts?
@@bosch3540 the hatch combings definitely add structural rigidity to the deck plating on the long unsupported spans that bridge the cargo holds. Similar to how a sheet of paper held on one edge horizontally won't support its own weight, but if you crease it, it will. The older lakers were built in a way that makes them far more stiff than "modern" lake vessels which bend and flex even in seas as small as 6ft. From what I've seen though, ships on the lakes are generally built and engineered to work within the limitations created by shore side infrastructure (locks and docks). The goal is to load as quickly as possible so if the ship lines up with the dock, there's less shifting of the boat at the dock which saves time. Even modern boats like the Edwin H Gott and the Edgar B Speer are designed to line up perfectly with the loading shuttles in Two Harbors, MN.
This is yet another Efficient Method besides Trains that Deliver Goods. Thanks for making the trip and sharing the video. 👍🙏
Thank you very much.
I'm glad you enjoyed it.
It looks like it's unloading sand, which can be used for fracking and other uses. The Saginaw is an interesting vessel. I have seen it in the St. Mary's river when I was up there. The paint on the sides of these Great Lakes vessels tend to get scraped-up from going through the Soo Locks. They hug one side of the lock to help keep the vessel straight in the lock.
That is wind driven chop/waves. Another fascinating video! Lived near this stuff most of my life, have no idea how it works/operates lol. Well done and thanks for sharing 🤠
That boat is unloading at Kuhlman Corporation's facility. Kuhlman is a ready-mix concrete supplier however it looks like they also handle road salt which is piled up under the black tarps.
The product could be a washed aggregate, because if you look further back in the yard you can see white concrete trucks lined up. Great video!
One of the incarnations of the John J Boland. A current John J. Boland sails the lakes today under that name.
Another excellent video! Love these old ships.
Awesome video I’m from Temperance MI and get to see this every so often my aunt lives on the Maumee River in Toledo thanks for sharing
Great Video As Always Man! 👍 Really Great Footage & Narration!
Hey Jackson!
I've got a video I'm working on in which I follow the Cardinal from Kenova to Staunton and then back.
I hope to have it out within the week.
@@nkyrailfan Cool! I’ll be sure to Tune In!
Interesting operation!
Really enjoy these very well narrated videos.
Thank you very much.
I'm glad you enjoy them.
That is the Anderson/Cargill facility. They could unloading potassium or something similar for use in fertilizer. Not sure tho..
The older the boat the more hatches. You unload the boat with a predetermined series of gates. It’s spaced out so the boat settles evenly. A crew member is in the unloading tunnel opening and closing gates to allow cargo from the holds to go onto the belt. It’s a beautiful choreographed system. That could be wheat they are unloading but I’m sure as I ever worked a boat that did grain
Thanks for the great info!
I do appreciate it.
Love these videos
70 years old? That'll be the Jones Act in literal action.
They can break the holds into smaller spaces between the hatch covers, useful if loading multiple cargo types and to limit the mobility of any bulk cargo if they can't fill the full hold with what is available.
yes, bulk cargo shifts with the wave action out on the lakes, this can unbalance the ship and if severe enough capsize it so limiting the space it has to move in is a big safety issue.
Well done. Thanks.
thanks for these interesting videos
very interesting thanks for filming and sharing looking forward to your upcoming videos on CSX
Great history
The one large silo nearby has a sign, "The Andersons" on its side, which means it might be a grain like wheat.
Doubt very much that grain is being unloaded. Grain in general is shipped out of Toledo. In looking at Google maps, this is being unloaded at the Kulhman facility, a concrete company, so it is probably sand or aggregate, at least something used in concrete. The Anderson grain facility is next door to the left and generally ships out grain.
Both Anderson's river facilities (on either side of Kuhlman)send grain put by by freighter. However, the Mondelez facility (formerly Nabisco, downriver next to the shipyard) receives grain from freighters.
the Saginaw was unloading at Anderson's Grain and Ethanol So it could have been either corn or another type of grain but my guess is corn.
Retired Ocean-Going 2nd Mate: Discharge procedure. I will GUESS that they follow a routine discharge procedure like we did in order to not overstress the hull. Discharge product: it would be helpful to know the name of the dock, then we can look up what cargoes they handle.
Thanks for the detailed information.
I really do appreciate it.
On these forward bridge boats, are there two galleys/messes, or do they just have to schlep the length of the boat ? One presumes the Captain and offucers don't have to make the trek aft.
There is only one galley. If there is bad weather, they have a below decks passage that they use to get back and forth.😵💫
0:48 to add a little footnote to your comment that the ships last a long time as they do the Edmund Fitzgerald sure didn’t last a long time unfortunately from when it was laid to when it sank
Since freshwater is less corrosive to ships than seawater, many lakers can remain in service for longer periods.[14] The average lifespan of a laker is 40-50 years
You'd by lucky to get half of that life out of a seagoing ship. First because the corrosion is faster with salt water, but also there is less tolerance of hull weakening due to the much bigger waves on heavy seas, compared with lakes. Many, many seafarers have been lost with structural failure of bulk carriers in heavy seas. Their hulls are very weak due to the big hatch holes in the top.
The cargo might be wood pellets. Resolute Forest products has a pellet facility in Thunder bay - it would look like grain but be larger. I recently put together this video - ua-cam.com/video/AfT8Y1ut0ag/v-deo.html The cargo being loaded at the end was wood pellets. I'm jealous you caught the unloading operation with all the hatches open.
Thanks for the info and sharing the video.
I'm going to watch it right now.
I think what is being unloaded is wheat.
Grain at the Andersons terminal
I prefer the older boats. The newer ones lack distinctiveness and almost look like (ocean-going) container ships. It's the lack of a forward superstructure that makes the difference. It may be safer, cheaper and more efficient to have all the superstructure it the stern. Well, those are what count, not looks or tradition.
waves are solely wind here it;s either wind or a surface action like a passing ships that causes waves!! as for the hatch size those old boats were built exclusively to haul iron ore nothing else!
The Saginaw looks like it desperately needs a new paint job. But of course that is indeed pricey.
thats probably less then 5 years of wear. these lake boats take a beating in the locks. Ships require a 5 year drydock survey, and they usually get repainted then. A quick google found an article that she was dry-docked in January 2022
Looks like grain. Waves are created by the wind.
This may Barly that she is hauling.
The ships last long because they only sail on fresh water...they are called saltees😂
I guess when they were younger, they were in their - Salt-eens. I'll get the lights.
Aren’t salties ships that travel into the lakes from the ocean?
Saltees refers to ocean going ships with the reference to salt water.Edit saltees also are distinguishable because most of them have a bulbous bow
@@mattharper588 Exactly what I thought. Thanks for the confirmation! 🇨🇦

Friendly hint. You are using an electronic camera, recording on memory media. Ergo, you are NOT "filming". This is the 21st Century.
What is he doing then? Memorying? Mediaing? No, he is filming. That is what it is called.
Can't he just say he's making a video ?
Pedant
I still 'dial' a number on my smart phone. I'm sure You know what I am doing.
Whatever the cargo is . Automation certainly makes it better, pretty good video thanks.🦺🙋
