Radar Piloting Tools, at Your Serviceosco Busan sailed from Oakland Harbor in a dense fog. With a pilot and the master on the bridge, it was navigating primarily by electronic chart (ECDIS). As the ship approached the Oakland Bay Bridge, the pilot could no longer see. He became confused about the ECDIS display and made a late turn. The ship scraped along the bridge support pier, holing its port side in the process and spilling 53,569 gallons of fuel.
Dozens of factors contributed to this disaster—not the least of which was the decision to sail in zero visibility. However, in reviewing the radar images from the voyage data recorder (VDR), there were clearly missed opportunities to make it safely through the bridge span.
