Hanwha Ocean announced the order for four container vessels, each with a capacity of approximately 13,000 teu, on Friday.
These vessels are scheduled for delivery by February 2029.
Moreover, HMM will pay approximately 1.07 trillion won ($732 million) to Hanwha Ocean for this order.
Hanwha Ocean did not mention that the vessels will be LNG-powered.
However, HMM said last month that it had decided to place orders for 12 LNG dual-fuel container vessels and two very large crude carriers.
According to HMM, the total investment is worth $2.82 billion, or 4.3 trillion won, and it expects to complete the project by April 2029.
The firm said that the LNG dual-fuel container vessels will each have a capacity of 13,000 teu, but it did not provide further details.
Earlier this week, HMM placed orders for eight LNG dual-fuel container vessels at two HD Hyundai yards.
Under the first order, HD Hyundai Samho will build six LNG dual-fuel container vessels, each with a capacity of 13,400 teu.
These vessels are scheduled for delivery by April 2029.
HMM will pay approximately 1.6 trillion won ($1.09 billion) to HD Hyundai Samho for this order.
Under the second order, HD Hyundai Heavy will build two LNG dual-fuel container vessels of the same size.
These vessels are scheduled for delivery by July 2028.
The HD Hyundai Heavy vessels are worth 534.6 billion won ($364 million).
