In the evening of October 17,2012,the vessel Hangjun 12 of Changhang Wuhan Engineering Bureau was struck by lightning when working in Malaysia red ridge channel. In the lightning accident,the weather instrument of the ship was destroyed by the lightning to the ground,and the electronic information equipment in the vessel was influenced by induction lightning,which had damaged the electronic information system and electrical equipment. According to the Code for Design Protection of Structures against Lightning( GB 50057-2010),this lightning accident suffered by Hangjun 12 was analyzed theoretically from aspects of the protection scope of the two lightning rods,main measures against lightning electromagnetic impulse,and specific reasons for the lightning accident. Finally,some measures to prevent the ship from being struck by lightning were put forward,such as improving countermeasures against direct lightning flash,enhancing equipotential bonding and shielding measures and so forth.
