In December 2025, the methanol‑fueled dual‑power vessel "Jinjianghai 316", owned by Tongling Jinjiang Shipping & Trading Co., Ltd., successfully obtained its operation certificate and officially set sail! This milestone not only achieved a "zero breakthrough" for new energy vessels in Tongling City, but also marked a new phase in the development of green shipping along the Yangtze River basin — and the "power heart" and "energy hub" of this green vessel are precisely the methanol storage tanks and gas supply system custom‑built by Defon Hubei Marine Power Co., Ltd.
As a main vessel with a length of 92 meters and a designed deadweight of 3,922.14 tons, the "Jinjianghai 316" has extremely high requirements for the safety, adaptability, and stability of its core equipment.
Leveraging years of technical expertise and engineering experience in the marine sector, Defon has
designed the storage tanks with corrosion‑resistant structures,
precisely adapted tomethanol fuel characteristics,
to build a solid safety line from the source;
the gas supply system innovatively achieves a highly integrated skid‑mounted layout,
perfectly fitting the limited space on board,
significantly improving installation and maintenance efficiency.
This core system achieves millisecond‑level precise matching with the vessel's dual‑power unit, intelligently responding to different sailing conditions, and continuously and stably supplying methanol fuel, providing a solid guarantee for efficient navigation.
Empowered by Defon's core equipment technology,
the "Jinjianghai 316" achieves a dual leap
in environmental and operational benefits:
during navigation,soot generation is greatly reduced,
and emissions of harmful gases such as carbon monoxide and nitrogen oxides are significantly lowered,
truly practicing the "green shipping" concept;
meanwhile, the system's high reliability and intelligent adaptability
help the vesselreduce overall operating costs,
achieving a win‑win for both environmental protection and economic benefits.
This successful cooperation with "Jinjianghai 316" is not only a strong verification of Defon Hubei's technical strength, but also provides valuable equipment application experience for the promotion and application of new energy vessels in the Yangtze River basin, injecting strong momentum into the green and low‑carbon transformation of the water transport industry with hard‑core technical practice.
From now on, Defon Hubei can provide a complete methanol system, and it has been verified on actual vessels! Our business covers the construction and installation of methanol stations, as well as core equipment such as methanol filling skids, methanol supply skids, methanol storage tanks, and methanol bunkering skids, together with supporting special pipeline fittings such as double‑wall rigid pipes for methanol engines and flexible double‑wall hoses for methanol connection, covering the entire chain to meet methanol energy application needs.
