Quick answer: JIEXI provided AUS40 marine urea bunkering for a vessel calling Tianjin Port, China. The operation used a standard 40 m³/h dual-pump linkage system and transferred 40 m³ of AUS40 in 1.5 hours of continuous bunkering. Project records indicate that the work was completed within the scheduled port window without vessel detention.

AUS40 marine urea bunkering for an international vessel calling Tianjin Port.
Tianjin Port is a key international shipping hub in the Bohai Rim. It serves ocean-going container ships, bulk carriers and Ro-Ro vessels operating on tight port schedules. Vessels equipped with SCR exhaust after-treatment systems require AUS40 marine urea solution to support NOx emission compliance under IMO MARPOL Annex VI Tier III.
For this project, the key requirements were not limited to product supply. The operation also needed fast mobilization, reliable product quality, safe transfer, accurate measurement and complete documentation within the vessel’s available port window.
Short port window: Limited berth stay time required fast mobilization and coordinated delivery to avoid affecting the vessel’s schedule.
Product purity: AUS40 must meet the specified quality requirements. Impurities can affect SCR catalyst performance, making batch quality control and traceability important.
Port coordination: The operation required coordination with the vessel, agent and terminal, including transfer arrangements, metering and documentation.
Winter conditions: Low temperatures in North China require attention to anti-freezing and anti-crystallization measures during storage and transfer.
Product and compliance: JIEXI supplied AUS40 marine urea against GB/T 35176.1 and ISO 18611, with batch COA and traceability records available.
Bunkering arrangement: The vessel was supplied at berth in Tianjin Port.
Equipment and transfer: The operation used a standard 40 m³/h dual-pump linkage system. A total of 40 m³ of AUS40 was transferred during 1.5 hours of continuous bunkering.
Safe handling and measurement: The operation included a sealed transfer pipeline, real-time flow monitoring and accurate metering.
Documentation package: The project provided a delivery receipt, certificate of analysis and bunkering delivery note for inspection records.
Winter precautions: Thermal preservation measures were used to reduce the risk of urea crystallization and pipeline blockage during cold-weather storage and transfer.
The AUS40 bunkering operation was completed within the scheduled port window. Project records indicate that no vessel detention occurred.
The supplied product was supported by batch documentation and traceability records. This gives the vessel’s technical and compliance teams a clear record of the delivery, product standard and transferred volume.
The project demonstrates how a coordinated AUS40 supply arrangement can support vessels that need to complete bunkering during a short Tianjin Port call.
Support for emission compliance: AUS40 supplied to the required product standards helps support the operation of SCR systems used for Tier III emission compliance.
Reduced operational disruption: Advance coordination and fast transfer help fit the bunkering operation into the vessel’s available port window.
Clear documentation: Batch COA, delivery receipt, bunkering delivery note and traceability records simplify internal review and inspection preparation.
Easier communication: Shipowners and ship management companies can discuss the required volume, delivery mode and documentation directly with one service contact.
