The largest ballast capacity and strongest deck strength in the class.
TENSHO has the largest ballast ability and strongest deck strength in 5,000 tons of deadweight class. The capacity of ballast adjustment is approximately 50cm/hour with no similarities seen in the same class. Therefore, she can perform the roll-on/off operation safely and promptly despite big movement of tide level in the port. Moreover, the deck strength is 15 ton/m2, which exceeds that of larger barge, and she can handle large cargos and/or concentrated load of cargos with an enough margin.
