TSUNEISHI GROUP (ZHOUSHAN) SHIPBUILDING has successfully delivered its second Methanol Dual-Fuelled 5,900 TEU Type Container vessel, marking a major milestone in the continuous, cross-border series production of its largest alternative-fuel vessel class. Equipped with advanced dual-fuel main engines, methanol-powered auxiliary generators, and energy-saving hull technologies, the vessel provides a high-spec, zero-carbon-ready shipping solution that directly aligns with tightening international regulations like FuelEU Maritime.
Zhoushan, China | May 8, 2026 – Reinforcing its pivot toward mass-producing alternative-fuel vessels outside of Japan, TSUNEISHI GROUP (ZHOUSHAN) SHIPBUILDING INC. (TZS) has officially delivered its second Methanol Dual-Fuelled 5,900 TEU Type Container Vessel.
The delivery, completed on April 30, 2026, marks the second handover of this zero-carbon-ready design in less than three months. It signals that the shipbuilder’s global production framework for next-generation methane-pathway and alcohol-fueled vessels is moving from boutique engineering into high-gear series production.
Global Production Milestone for TZS
The handover follows the February 3, 2026, delivery of the series’ first vessel, which was immediately placed on a long-term charter with Danish container shipping giant A.P. Moller – Maersk.
While Tsuneishi spearheaded its methanol dual-fuel rollout within Japan (delivering a pioneering Ultramax bulk carrier in May 2025) and via its Philippine base at Cebu (handing over the world’s first methanol Kamsarmax in January 2026), this second Chinese delivery proves that the complex design, piping, and safety protocols required for volatile green fuels have successfully scaled across borders.
Industry Impact: “The delivery demonstrates that TSUNEISHI SHIPBUILDING has entered a phase in which alternative-fuel vessels can be built continuously at overseas manufacturing bases.”
Technical Specifications: Maximizing Cargo and Efficiency
The 5,900 TEU series represents the largest class of container vessel ever constructed by the Tsuneishi Group. It has been deliberately optimized to balance aggressive environmental compliance with commercial deadweight requirements.
| Metric / Feature | Specification |
| Max Capacity | 5,915 TEU (Hold & Deck combined) |
| Reefer Capacity | 1,400 Containers (Catering to high-value refrigerated cargo) |
| Main Engine | Dual-Fuel Propulsion (Methanol / Conventional Fuel Oil) |
| Auxiliary Power | HD Hyundai HiMSEN (8H32DF-LM) Methanol-Fuelled Generators |
| Eco-Tech Features | Proprietary MT-FAST energy-saving hull attachments & Shaft Generator |
| Fuel Tank Engineering | Constructed using low-CO2 blast furnace Kobenable® Steel |
Achieving Net-Zero Operations: The Methanol Advantage
Unlike first-generation dual-fuel vessels that only utilize alternative power for primary propulsion, this 5,900 TEU class approaches a “final solution” for operational greenhouse gas (GHG) reductions.
Full-Spectrum Methanol Combustion
By opting for HD Hyundai HiMSEN dual-fuel auxiliary engines, the vessel can run both its main propulsion and its on-board electrical generators on green methanol. Barring a negligible amount of conventional pilot fuel required for ignition, the ship can eliminate nearly all operational carbon emissions when utilizing sustainably sourced e-methanol or bio-methanol.
Port-Side Decarbonization
The container carrier features large-capacity Alternative Maritime Power (AMP) systems. This enables the crew to completely shut down its auxiliary engines and connect to shore power while berthed, wiping out localized port emissions (SOx, NOx, and particulate matter).
Advanced Hydrodynamics
To offset the lower energy density of methanol fuel, which typically requires larger storage volumes, Tsuneishi integrated an improved hull form alongside its MT-FAST technology. MT-FAST applies a series of stators behind the propeller to recover rotational energy from the propeller slipstream, improving fuel efficiency by up to 4% and maintaining competitive cargo hold volumes despite the added fuel-tank footprint.
Regulatory Alignment: Capitalizing on Decarbonization Mandates
The continuous rollout of Tsuneishi’s methanol portfolio lands at a critical commercial juncture. With the EU Emissions Trading System (EU ETS) clamping down on maritime carbon pricing and FuelEU Maritime penalizing high-GHG energy usage in European waters, international liner operators are actively hunting for tonnage that avoids severe regulatory penalties.
By delivering high-capacity reefer capabilities alongside a net-zero fuel profile, TZS has engineered a flexible vessel class suited for highly regulated trade lanes. Moving forward, the Tsuneishi Group intends to leverage the construction experience gained at its Zhoushan yard to expand its alternative-fuel portfolio across multiple vessel sizes and segments globally.
