Tsuneishi launches first next-generation dual-fuel container ship
On August 27, a Chinese shipyard belonging to Tsuneishi Shipbuilding Group marked a major milestone by launching its first next-generation energy-efficient container ship, capable of operating on dual fuels, including methanol. This is the largest container ship ever built by Tsuneishi and a cornerstone of the group’s strategy to lead in methanol-powered vessel construction.
Vessel specifications
-
Capacity: 5,915 TEU
-
Refrigerated containers: up to 1,400 reefer units
-
Technology: an optimized hull design and the patented MT-FAST system, improving propulsion efficiency by about 4% by regulating water flow with fins placed ahead of the propeller
-
Energy systems: the main engine and onboard generators, including HiMSEN (8H32DF-LM) from HD Hyundai, can operate on methanol; the vessel is also equipped with a shaft generator and shore power connection
The vessel is designed to run on green methanol as its primary fuel and is positioned as a “final solution” towards achieving net-zero CO₂ emissions.
Market context
Maersk is also expanding its methanol-powered fleet. In 2023, the company ordered six 9,000 TEU dual-fuel container ships from Yangzijiang Shipbuilding Group, scheduled for delivery between 2026 and 2027. In August 2024, Maersk announced a fleet renewal strategy, including 50–60 new vessels totaling 800,000 TEU, to be delivered between 2026 and 2030.
Tsuneishi’s outlook
-
Construction of the first vessel of this new class began in April 2025.
-
Final delivery is scheduled for February 2026.
-
In July 2025, Tsuneishi’s Philippine yard launched the world’s first dual-fuel Kamsarmax, followed in May by a dual-fuel Ultramax in Japan.
The company confirmed it will continue expanding the practical application of dual-fuel methanol-powered ships, positioning methanol as a cornerstone of its sustainable shipbuilding strategy.
