Tsuneishi Shipbuilding completes first block loading of methanol-fuelled newbuildings

Tsuneishi Shipbuilding on Tuesday (22 April) said its shipyard in China successfully completed the first block loading for its first 5,900TEU methanol-fuelled containership, which is the largest of this ship type built by the company, on 16 April.

In addition to the enhanced hull form and MT-FAST, the company’s innovative energy-saving technology, the integration of a large-capacity shaft generator has enabled this dual-fuel vessel to achieve both optimal loading performance and exceptional fuel economy when compared with 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 vessel has been developed based on the concept of a final solution for the zero CO₂ emission vessel through the use of green methanol. Therefore, not only the main engine but also all on-board generators, HiMSEN engine which will be supplied by HD Hyundai, can be methanol-fuelled. 

This makes it possible to achieve carbon neutrality with the exception of a small amount of pilot fuel. Furthermore, the vessel is equipped with the necessary infrastructure to receive large-capacity alternative maritime power supplies. 

“In addition, the generators can be deactivated during anchorage, thereby achieving zero CO₂ emissions. We will continue to promote the further practical application of methanol-fuelled vessels with the aim of achieving carbon neutrality in the future,” the company said.

Additionally, the Japan-based shipbuilder said its yard in the Philippines has successfully completed the first block loading for its first methanol dual-fuelled Kamsarmax bulk carrier on 21 April at THI Slipway No.2 . 

The vessel is scheduled to be launched in July 2025 and delivered in January 2026.

It is the first methanol-fuelled vessel in the Kamsarmax series, a long-standing series of vessels built by Tsuneishi Shipbuilding, which reached the 400-vessel milestone in July 2024.

By using methanol for propulsion, Tsuneishi Shipbuilding said the vessel reduces carbon dioxide emissions by 10%, nitrogen oxide emissions by 80% and sulphur oxide emissions by 99% during voyages compared to conventional models.
