In order to protect crew and vessels, Maersk Line revealed that a safety navigation zone had been established, with no ships getting within 140 nautical miles of the Fukushima plant.
In addition, the group said that no radiation level measurement at the ports called at had been exceeded, or even been close to, safety limits set by the International Maritime Dangerous Goods Code and the International Atomic Energy Agency, and there were no plans to cease calling at Japanese ports in operation.
