I spoke with Port of PDX about giving more specific instructions about barges at the dock and position of cranes. There was a minor comms issue reticently regarding barges and cranes. They will work on giving better info. Try to be very specific on questions. Crain up or down? Barge crane or container crane? Barges: container barges or  construction etc.. They will try to be more clear on what cranes and what barges.
