I work in the container port industry, we currently have two ships larger than the Dali at our port. We have no bridges here, but on our news the port of Vancouver is reviewing safety and procedures for their two large bridges. They differ in that they do require a tug escort in the harbour. I'm sure ports everywhere are reviewing emergency procedures. I understand the vessel lost power for navigation.
It was indeed a tragedy. but I hate to say better than it happened while the bridge was closed to traffic for maintenance, rather than during the day while open. Of course that is no comfort to the poor families of the workmen that died. How awful.
And meanwhile there is marine traffic stuck in the harbour without a way out, possibly for months. They say it is the largest port for vehicle imports along the eastern seaboard of US, so importers and exporters will be scrambling to find alternate ports.
