This video was just posted online with no information attached. Hard to tell exactly what happened, but looks like the ship had it coming for a while before the camera started rolling. If anyone has any details please share. And remember, safety first!
Update: Mystery solved! The ship here is the MV Unison Vigor, which sank in 2011 after it was struck by MV Ocean Flavor while berthed at the port of Siam Seaport in Thailand.
