November 25, 2024 Tsuneishi Shipbuilding Co., Ltd. (Fukuyama, Hiroshima, Japan) has launched the world's first 65,700 metric tons (MT) Methanol Dual Fuel Bulk Carrier TESS66 AEROLINE*1 (TESS66) on November 22, 2024 in TSUNEISHI Factory. This vessel is designed to operate with a low environmental impact using methanol fuel while utilizing TESS66's features of high load carrying capacity and fuel efficiency and is scheduled for delivery next spring. By using methanol as fuel, this vessel will reduce emissions of nitrogen oxides (NOx) by up to 80%, sulfur oxides (SOx) by up to 99% and carbon dioxide (CO2) by up to 10% compared with heavy oil. Furthermore, the use of green methanol*2 makes carbon neutral and contributes to reducing environmental impact. The large-capacity methanol fuel tank was placed on to maintain safety and simplicity in cargo loading and unloading, while at the same time ensuring loading performance. The vessel has a cargo hold capacity of 81,500 m3 and a deadweight of 65,700 mt, inheriting the characteristics of TESS66, which is the top class of loading capacity in Ultramax*3 category. In terms of fuel efficiency, the TESS66 also offers high performance for the use of a fuel-efficient main engine and our unique AEROLINE technology for reducing wind resistance.

"We were able to build and launch our 1st vessel of next generation, which we have been developing to achieve carbon neutrality in accordance with the 'Technology Development Roadmap' incorporated into our medium-term management policy. Starting with full in-house manufacturing of pressure tanks for LPG carriers delivered in January this year, we have also started full-scale manufacturing of LNG fuel tanks and the technology developed in the full in-house manufacturing of pressure tanks is being applied to the production of methanol fuel tanks. In the future, we will further strengthen our technology deployment and collaboration with group companies to build the vessels of methanol dual-fuelled at our overseas factories and lead the decarbonization of the shipbuilding and shipping industry as an environmentally friendly company." *1 TESS66 AEROLINE: This is our newest design which has achieved the largest in its category of deadweight. The width is kept to a Panamax-sized breadth and also the depth is kept to an industry-standard level, ensuring a high level of versatility. Product information: TESS66 AEROLINE| Poducts | Tuneishi Shipbuilding Co.,Ltd. *2 Green methanol: Green methanol refers to methanol synthesized from recovered CO2 (carbon dioxide), and hydrogen derived from renewable energy sources, or bio-methanol produced from biomass, and which is contribute to carbon neutral. *3 Ultramax: The name of the category of bulk carriers. It refers to vessels with a deadweight 60,000 MT and a crane on deck.
