Ocean Yield and Nippon Yusen Kaisha (NYK) have exercised options for four additional 200,000 cbm LNG carriers at HD Hyundai Heavy Industries, making all eight vessels in the programme effective, with deliveries expected by 2029.

The full eight-ship series will be placed on the same terms. Using the cost basis of the first tranche, Ocean Yield estimates the combined value of the eight newbuildings at about $2.08 billion.

All eight carriers are set to be chartered on a long-term basis by Cheniere Marketing International, a subsidiary of Cheniere Energy, under charter arrangements that have been concluded for the entire set. Charter contracts covering the first four vessels were made public on 5 February 2026.

Each vessel will have a cargo capacity of 200,000 cbm, exceeding conventional 174,000 cbm LNG carrier sizes and enabling higher lift per voyage. The design measures 294.8 m in length, 48.9 m in beam and 26.7 m in height.

The ships will incorporate technologies including a high-efficiency shaft generator and an LNG reliquefaction system, intended to improve operational efficiency.
