Hong Kong-based marine fuel supplier Chimbusco Pan Nation (CPN) on Tuesday (16 June) announced that its bunker barge Zhong Ran 23 has become the first vessel in Hong Kong listed on the Marine Department’s official List of Quality Bunker Vessels. The list under the Quality Bunker Operator Scheme launched on 3 June. “The Scheme is a voluntary initiative designed to raise the standard of bunkering accuracy, transparency, and service quality in Hong Kong,” CPN said in a social media post. “To be listed, a bunker vessel must have its Mass Flow Meter (MFM) system independently certified under ISO 22192, the international benchmark for mass flow metering in bunkering operations.” CPN added it has operated the MFM system across our fleet of fuel oil barges since 2015. Manifold Times previously reported Hong Kong’s Marine Department (MD) launching the Quality Bunker Operator Scheme to encourage bunker operators to install and use mass flow meter systems (MFM systems) on their bunker vessels. MD said the scheme aims to enhance Hong Kong’s bunkering service quality and the competitiveness of Hong Kong ports, thereby further consolidating Hong Kong’s position as an international maritime centre and a major bunkering port. Under the Scheme, bunker operators of traditional maritime fuel and biodiesel that install and use MFM systems on their bunker vessels, with the MFM systems inspected and certified by an accredited body in accordance with the International Organization for Standardization’s ISO 22192 Standard or equivalent requirements, can apply to the MD for inclusion in the scheme’s “List of Quality Bunker Vessels”, provided they meet the relevant technical and operational requirements.
