Dear Friends of Mine Who are Interested in Things,
So I crossed the Steel Bridge here in Portland on Saturday, and I noticed that a particularly large cargo ship was docked at the big concrete grain silos right next to the bridge. I also noticed that they were filling it with grain from big chutes at that very moment. Wow, I thought, how lucky that I pass by at the very moment that they're filling it.
Tonight, Monday, I took a walk after work and all of downtown seemed veiled in a haze from where I stood on the east side of the river. I walked down by the Steel Bridge again... and they were still loading grain. That's what was filling the air.
At first I thought that it was impossible that they could have been loading this whole time, but then I reconsidered. The boat, The Thai Prize, is the size of a mid-century office building, and mostly empty inside.
So, of course, I did some research as soon as I got home. Here's what I've learned so far:
That kind of ship is known as a Dry Bulk Carrier
Simply loading something that big can be very dangerous. Something like 200 ships broke apart from the 1980s to the 1990s. (The Thai Prize has a giant 'safety first - no smoking' warning painted across its "house")
The biggest ones are known as Capesize because they can't go through the Panama canal and have to go around the Cape.
Capesize ships hold at least 80,000 dry weight tonnes.
I can't find stats for the unloading rates at the port of Portland, nor can I find stats for the Thai Prize, but from what I read, it's not uncommon for ships to take 36 hours or more to unload.
Ships are amazing!:
