The price for each ship is between $100m to $125m for the decade long charter period, Taipei-listed Yang Ming announced.
In July 2018, Yang Ming had entered into charter agreements with Shoei Kisen Kaisha for five similar newbuilds.
The new ships are expected to be delivered from the second quarter of 2020 through to the third quarter of 2021.
Meanwhile, Yang Ming also announced that it will introduce a new intra-Asia service together with APL starting 21 February.
The new service, Korea-Vietnam-Malaysia service (KVM), will be operated with three 1,800-teu feeder vessels with one by Yang Ming and two by APL.
The 21-day port rotation will be Kwangyang, Busan, Kaohsiung, Ho Chi Minh, Port Klang, Singapore, Haiphong, Kaohsiung, Kwangyang.
“The new service is expected to connect Northeast Asia and Southeast Asia more efficiently and provide customers with more convenient and excellent delivery service,” Yang Ming stated.
