An MOL unit has ordered another three multipurpose ships at Honda Heavy Industries.
The Asiasis website cited local sources as saying Mitsui OSK Kinkai will take delivery of the 17,500-dwt vessels from June 2017 to June 2018.
They will come with two 75-ton cranes for operation on Asia to South-east Asia routes.
No price was revealed.
The company placed an order for three similar ships at Honda last May
