China (Zhejiang) Pilot Free Trade Zone on Tuesday (30 June) said it has completed the province’s first ship-to-ship (STS) methanol bunkering operation at a shipyard, marking a new milestone in Zhoushan’s efforts to expand its portfolio of alternative marine fuel bunkering services.
The operation took place recently at Qingshan West Berth No. 2 of Tsuneishi Group (Zhoushan) Shipbuilding, where Zhejiang Free Trade Zone PetroChina Fuel Oil’s bunker tanker JIA CHEN 17 supplied 795 metric tonnes (mt) of methanol to the newly built 5,900 TEU methanol dual-fuel container vessel MAERSK FLINDERS.
The bunkering operation was completed in approximately 5.5 hours, making it significantly more efficient than truck-to-ship methanol bunkering, which authorities said would have taken around nine times longer to deliver the same volume
According to local authorities, the operation is the first of its kind at a shipyard berth in Zhejiang Province, filling a gap in on-site bunkering capabilities for shipbuilding and repair yards. Zhoushan has previously conducted truck-to-ship methanol bunkering, truck- and ship-to-ship LNG bunkering, and blended biofuel bunkering operations.
The demonstration project forms part of Zhejiang’s strategy to develop green marine fuel bunkering under the China (Zhejiang) Pilot Free Trade Zone Bulk Commodity Resource Allocation Hub Development Plan, which calls for pilot bunkering of alternative fuels including green methanol, liquid hydrogen and ammonia.
Earlier this year, the China (Zhejiang) Pilot Free Trade Zone‘s Zhoushan Administrative Committee identified three priority projects: the world’s first anchorage ammonia bunkering operation, Zhejiang’s first shipyard-based STS methanol bunkering operation, and simultaneous LNG bunkering alongside cargo operations at Yongzhou Terminal, Ningbo-Zhoushan Port.
Authorities said the shipyard-based STS model offers operational advantages over both ship-to-ship and anchorage STS bunkering. In addition to reducing inter-island transport and lowering overall costs, conducting the operation alongside at the shipyard minimises weather-related disruptions and improves operational safety and schedule certainty.
