Hong Kong Launches Quality Bunker Operator Scheme to Drive MFM Adoption

The Hong Kong Marine Department has launched the voluntary Quality Bunker Operator Scheme, encouraging marine fuel suppliers to install ISO 22192-certified Mass Flow Meter (MFM) systems to boost delivery transparency and port competitiveness. The initiative establishes an official “List of Quality Bunker Vessels” for compliant traditional and biodiesel operators, alongside a new mandate requiring MFMs on all methanol bunker vessels by the end of 2026.

Hong Kong | June 3, 2026 – In a major push to enhance market transparency and defend its status as a top-tier global refuelling hub, the Marine Department (MD) of Hong Kong has officially launched the Quality Bunker Operator Scheme. The voluntary initiative is designed to incentivize marine fuel suppliers to install and utilize certified Mass Flow Meter (MFM) systems on their bunker tankers.

The move addresses long-standing international shipping demands for higher measurement precision during custody transfers. By formalizing a standardized verification framework, Hong Kong aims to eliminate volumetric disputes, accelerate turnaround times, and boost its port competitiveness against regional rivals like Singapore, where MFM usage has been legally mandated since 2017.

Driving Transparency in the Greater Bay Area

Hong Kong has historically maintained a dominant position in the regional bunker market. It consistently ranks as the world’s seventh-largest bunkering port, the second-largest in China, and the largest single refuelling hub within the Greater Bay Area (GBA).

However, as shipowners face tightening margins and stricter environmental reporting metrics, the demand for verifiable fuel data has surged. Volumetric measurement methods, such as manual tank gauging, are increasingly viewed by international liner lines as outdated and prone to error or manipulation.

Hong Kong Bunkering Market Profile

• Global Rank: 7th largest bunkering port worldwide.
• National Rank: 2nd largest bunkering port in China.
• Regional Rank: Largest bunkering hub in the Greater Bay Area (GBA).
• Primary Fuel Scope: Traditional marine fuel oils, marine gas oil, and biodiesel.

The launch of the scheme marks a deliberate shift by the Marine Department toward digitalized, transparent infrastructure to secure high-volume trans-Pacific and intra-Asia shipping traffic.

The Technical Framework: ISO 22192 Compliance

To qualify for the Marine Department’s newly established “List of Quality Bunker Vessels,” bunker operators must meet strict international technical benchmarks.

The scheme applies directly to operators of traditional marine fuels and bio-distillate blends. To secure a listing, operators must ensure their onboard MFM systems are rigorously inspected, calibrated, and certified by an independent, accredited body.

Quality Bunker Operator Scheme Validation Pathway:

• System Installation: Mass Flow Meter (MFM) integrated on bunker vessel
• Technical Audit: Verification by accredited third-party body
• Regulatory Standard: Strict compliance with ISO 22192 requirements
• Market Recognition: Official publication on MD’s “List of Quality Bunker Vessels”

The core technical standard underpinning the scheme is ISO 22192 (Bunkering of marine fuel using mass flow meter system). This international standard governs the entire custody transfer process, ensuring the meter’s security seals, software integrity, and environmental working conditions prevent data tampering and guarantee true mass-based measurement.

Strategic Shift: Mandatory MFMs for Green Methanol

While the Quality Bunker Operator Scheme is currently voluntary for conventional fuels and biodiesels, the Marine Department is using the launch to telegraph a much stricter regulatory stance for the fast-approaching green fuel era.

The MD spokesman confirmed that Hong Kong will mandate the use of MFM systems on all methanol bunker vessels within 2026.

Because alternative low-carbon fuels like green methanol have lower energy densities and higher capital costs per metric ton compared to heavy fuel oil, absolute precision during bunkering is non-negotiable for shipowners. By making MFMs mandatory for alternative fuels from day one, Hong Kong is positioning its port infrastructure to become the primary green refuelling corridor in East Asia.

Industry Implications and Commercial Incentives

For participating bunker companies, the commercial benefits extend beyond public recognition on the Marine Department’s portal. Operators who adopt certified MFMs stand to gain significant operational efficiencies:

“In addition to receiving recognition from the MD, participating bunker operators will benefit from enhanced corporate image and competitiveness through the adoption of MFM systems, thereby boosting customers’ confidence and helping to create new business opportunities.” — Marine Department Spokesman

The shipping lines themselves are expected to heavily favor operators on the “Quality Bunker Vessels” list. Automated MFM logging slashes bunkering times by up to three hours per stems by eliminating prolonged manual post-bunker sounding disputes, allowing container lines and bulkers to meet tight port rotation windows.

Administrative Infrastructure

Applications for the Quality Bunker Operator Scheme have opened immediately. The Marine Department has established a dedicated administrative channel via its Green Maritime Fuel Team to process system technical reviews and handle industry queries. Interested operators can access formal documentation and submit system schematics directly through the Marine Department’s centralized portal or via direct regulatory communication channels (greenfuel @mardep.gov.hk).
