Here is the Harvester heading in to Hamilton Harbour bringing a load of iron ore pellets to DOFASCO. One of the questions I've always had is how are these ships unloaded. There are 17 hatches altogether, 11 of which are in this picture. They fold back or are lifted sideways to open, and then this ship depends on dockside cranes to unload the cargo.
In a gearless bulk carrier like this (ie. having no onboard cranes) this usually involves enormous double clamshell grabs that are dropped into the hold, lift out the cargo, and transfer it to onshore. This night-time shot from the Canadian Geographic shows both a large clamshell grab, and below it a large front end loader being lifted down into the hold. As the grab bucket nears emptying the hold, a front end loader is used to keep scraping the remaining cargo into a central pile so the grabber can lift it out. Crew climb down and help the final bit of this process with shovels.
If you want to read the Canadian Geographic article, you find it here, plus a number of more pictures here.
If you want to follow ships on the lakes, the websites 'boatnerd' and 'vesselfinder' are useful. The website 'marinetraffic' has an incredible live map showing where all ships in the world are at a given point in time.
Tabor asked yesterday 'how did I know all this stuff? The answer is simple - I don't. But on a topic that I find particularly interesting, I will enjoyably spend a few hours looking things up.
