Tsuneishi Shipbuilding launches new methanol dual-fuel containership in China

Japan’s Tsuneishi Shipbuilding on Thursday (28 August) announced its shipyard in China, Tsuneishi Group (Zhoushan) Shipbuilding (TZS), successfully launched a methanol dual-fuel containership on 27 August.

The 5,900 TEU vessel, the largest container vessel ever built by Tsuneishi Group, will be delivered in February 2026.

In response to the growing demand for refrigerated transport in recent years, the vessel can also carry up to 1,400 reefer containers. Alongside an improved hull form and the Group’s proprietary energy-saving technology, MT-FAST, the adoption of a large-capacity shaft generator enables this dual-fuel vessel to achieve both top loading capacity and fuel efficiency, even when compared with conventional fuel oil vessels in the same segment.

MT-FAST is an energy-saving device that improves propulsion efficiency by approximately 4% by regulating water flow through the installation of multiple fins in front of the propeller. It was developed jointly with MTI of the NYK Group.

The main engine and also the on-board generators – including the HiMSEN engine (8H32DF-LM) manufactured by HD Hyundai – are capable of operating on methanol fuel.

In addition, the vessel is equipped with systems compatible with large-capacity shore power supply, enabling the generators to be shut down while in port, thereby further accelerating CO₂ reduction.

Mr Murakami Yoshifumi, President and Director of TZS, said: “The launch of this methanol dual-fuelled 5,900 TEU type container ship marks a historic milestone for TZS. 

“We are actively engaged in the construction of next-generation, environmentally responsible vessels, enhancing the value of ships while ensuring the highest standards of safety and quality.”
