Zhoushan Hi-Tech Zone Administrative Committee on Wednesday (7 January) said Zhoushan recorded a bonded bunkering volume of 8.03 million metric tonnes (mt) in 2025, marking a year-on-year increase of 10.6%.

The committee said this is the first time the port has hit the 8 million mt mark for the first time, potentially ranking among the top three bunkering ports globally. 

Manifold Times previously reported Zhoushan delivering 7.26 million mt of marine fuel in 2024.

The committee highlighted the efforts to improve service, cost, and efficiency, while implementing 41 targeted measures in 2025. 

Efforts were made in key areas such as accelerating green transformation, optimising digital supervision, facilitating anchorage bunkering, and consolidating cost advantages, driving comprehensive improvement in the quality and efficiency of industrial development. 

In line with the global trend of green transformation of marine fuel, the city has introduced management measures for green bunkering operations, a joint supervision mechanism for bunkering vessels, and an action plan for green transformation of bunkering, thus improving the regulatory and service system. 

The city achieved nearly 120,000 mt of biofuel bunkering. Zhoushan also put into operation an LNG bonded warehouse, commenced construction of the first methanol bunkering vessel, and established the first liquid ammonia bunkering company, accelerating the development of alternative bunker fuels such as LNG, methanol, and ammonia.

The city has continuously explored reforms and innovations in a bunker measurement system, releasing the first provincial standard for mass flow meters in China. 

It has conducted compliance inspections, statutory verifications, and pilot certifications for the installation and use of mass flow meters on barges, and implemented an online e-BDN system, successfully completing trials and entering routine operation. 

This has significantly simplified the processes of metering, handover, and verification, making the city the first in the country to achieve fully digital handover of the bonded fuel bunkering process. 

In July 2025, Zhoushan became the first port in China and third in the world to implement electronic bunker delivery notes (e-BDN) after issuing its first. 

A series of convenient anchorage measures were implemented. Provincial and municipal customs, maritime, and border inspection departments issued a package of facilitation support measures. 

They assessed and optimised nighttime supply conditions, added priority anchorages for bunkering, expanded the number of night time supply barges, and innovatively implemented a “one-window” service for refuelling vessels throughout the customs area, separate supervision and verification for large and small vessels, and simultaneous bunkering and cargo operations (SIMOPS). 

These measures further simplified customs clearance procedures at Zhoushan Port and effectively improved anchorage turnover efficiency and carrying capacity. 

With that, the bunker volume at Zhoushan anchorage reached 2.85 million mt in 2025, a year-on-year increase of 19.1%, becoming the core driving force for market growth. Among them, the bunker volume at Xiushan East anchorage reached 1.48 million mt, a year-on-year increase of 33.45%.

As for infrastructure, the city has accelerated storage and transportation projects for commissioning and expansion, adding 2.53 million cubic metres (m3) of oil and gas storage capacity.

The committee added that specialised policies, such as the “Implementation Opinions on Supporting the High-Quality Development of Zhoushan’s Bonded Marine Fuel Bunkering Industry,” was also introduced to drive cost reduction and efficiency improvement for enterprises.
