Tsuneishi Shipbuilding, a Japan-based shipbuilder, has delivered a 5,900 TEU methanol dual-fuel container ship chartered by Maersk, as it looks to extend construction of alternative-fuel vessels across its global yard network.
The vessel was handed over on February 3, the company said, describing the project as an important step in enabling methanol-fuelled newbuildings to be constructed at overseas facilities rather than solely at domestic yards.
Tsuneishi has been building up its methanol-fuelled ship portfolio across multiple segments. In May 2025 it completed a methanol dual-fuel UltraMax bulk carrier at its Fukuyama yard in Japan, followed in January 2026 by what it said was the world’s first methanol dual-fuel Kamsarmax bulk carrier at its Cebu yard in the Philippines.
The latest containership delivery demonstrates that the design and engineering expertise developed at its Japanese and Philippine bases can be applied across additional international locations. The company said this reflects a transition from isolated alternative-fuel projects towards a more mature, globally coordinated construction system.
Tsuneishi said the milestone strengthens its ability to develop next-generation fuelled ships across different vessel types and shipbuilding bases, with methanol identified as a key pathway. The firm plans to continue expanding construction of alternative-fuel tonnage through collaboration between its yards in Japan and overseas.
Yukio Okumura, Representative Director, President and Executive Director of Tsuneishi Shipbuilding, said:
“The completion of this methanol dual-fuel container ship at TZS marks a significant step forward for our company, enabling us to continuously build new fuel vessels at overseas bases. The ability to extend our design and construction experience, accumulated at our bases in Japan and the Philippines, to overseas locations, including our TZS base in China, represents a major advancement in our multi-ship type and multi-base new fuel vessel construction efforts. Moving forward, we will continue to prioritize safety and quality, steadily advancing the construction of new fuel vessels within a globalized construction system that integrates our Japanese and overseas bases.”
