I’m curious to know how many ships have been stranded inside the port. Those are the only things facing a long-term stoppage while this gets sorted out. The maritime shipping industry and their landside partners in the trucking and railroad industries probably had their contingency operation plans in action within 15 minutes of the incident, diverting cargo to neighboring ports with as little disruption as possible.
My understanding, 40.
