China's largest RoRo 'Bohai Emerald Bead' with the longest reach leaves Yantai Port in East China. Different from ordinary ships, the 36,000 displacement civilian passenger and roll-on/roll-off ship was constructed in accordance with national defense requirements in mind in its design and construction so that it can carry organic troop units and heavy equipment. The 178-meter-long and 28-meter-breadth ship can carry 2,000-plus persons and be loaded with over 300 vehicles of various sizes simultaneously. The "Bohai Emerald Bead" is the first ship of its kind to be built in China, and there are three more of the same design under construction.
