TSUNEISHI SHIPBUILDING Co., Ltd. has delivered the world’s first methanol dual-fuelled bulk carrier in the 65,700 deadweight ton class, the TESS66 AEROLINE, at its TSUNEISHI Factory on May 13, according to the company's release.
The vessel maintains a cargo hold capacity of 81,500 m³ and incorporates a fuel-efficient main engine alongside TSUNEISHI’s proprietary AEROLINE technology to reduce wind resistance.
The TESS66 uses methanol to reduce nitrogen oxides (NOx) emissions by up to 80%, sulfur oxides (SOx) by up to 99%, and carbon dioxide (CO2) by up to 10% compared to conventional heavy fuel oil. When operating with green methanol, the vessel supports carbon neutrality.
The methanol fuel tank is positioned to ensure safety and facilitate cargo handling while preserving loading efficiency.
Mr. OKUMURA Sachio, Representative Director, President & Executive Officer of TSUNEISHI SHIPBUILDING Co., Ltd., stated: “It is both an honour and deeply meaningful milestone for us to deliver the world’s first methanol dual-fuelled bulk carrier, the TESS66 AEROLINE.

I extend my sincere appreciation to all. This delivery marks just beginning. We will continue constructing methanol dual-fuelled vessels at our overseas facilities and remain steadfast in our pursuit of technological innovation to contribute to a more sustainable maritime industry and global environment.”
