Check out this incredible video of this ship turning on a 30 degree angle dump its cargo into the water. Via Core77.
Once upon a time, sawmills were located exclusively on rivers. Being next to water had multiple advantages: Trees felled upstream were simply floated down the river to the mill, easing transport; a backlog (pardon the pun) of logs could be left floating in the water as temporary storage; a waterwheel in the river could power the actual sawblade; and boats could easily access the sawmill to take the finished lumber away.
It’s been a long time since lumberjacks routinely floated logs down a river, but waterborne vessels are of course still used to transport lumber. This week an amazing video surfaced of the Seaspan Harvester, a timber barge designed to unload its cargo in a crazy way—by tilting sideways to dump it into the water.
So how does that work? By gaming the ballast tanks, the ship can be made to tilt 30 degrees to the side, then gravity takes care of the rest.
