en.Wedoany.com Reported - Tsuneishi Factory, part of China's Tsuneishi Shipbuilding, announced the delivery of the world's first LNG dual-fuel Kamsarmax bulk carrier, the "OCEANA FRONTIER".

The "OCEANA FRONTIER" is equipped with dual-fuel engines capable of operating primarily on LNG. Compared to traditional heavy fuel oil, the use of LNG fuel is expected to reduce carbon dioxide (CO₂) emissions while significantly lowering emissions of sulfur oxides (SOx) and nitrogen oxides (NOx).

Furthermore, through energy-saving technologies such as optimized hull performance and integrated shaft generators, the Energy Efficiency Design Index (EEDI) of the "OCEANA FRONTIER" is reduced by over 50% compared to the baseline, far exceeding the Phase 3 requirement of a 30% reduction set to take effect from 2025.

Tsuneishi Shipbuilding stated that a key feature of the "OCEANA FRONTIER" is the installation of an independent Type C pressure tank LNG fuel tank on the aft deck area. Manufacturing the LNG fuel tank requires advanced capabilities, including precision machining of special materials, high-quality welding, and insulation systems suitable for cryogenic environments. All related processes were completed within Tsuneishi Shipbuilding's own facilities.

Additionally, the cryogenic and pressure-handling technologies mastered through the development of the LNG fuel tank can be extended in the future to fuel tank solutions such as ammonia fuel tanks. As the shipping industry continues to explore various alternative fuel options, these technologies will form the foundation for supporting the transition to zero-emission vessels.

A Tsuneishi Shipbuilding representative said, "The pressure vessel manufacturing technology and quality management experience accumulated through the in-house production of LPG fuel tanks have been successfully applied to the LNG fuel tank of the 'OCEANA FRONTIER'. LNG requires handling under cryogenic conditions, which demands advanced capabilities in material selection, manufacturing, welding, and insulation."
