The internal test of an Endress+Hauser Coriolis master meter which will be used by the Singapore bunkering industry for future verification/proving of its mass flow meters (MFMs) was being conducted at Jurong Port on Wednesday (5 February).

The master meter was utilised to carry out a performance verification test of the MFM unit installed on board Singapore bunker tanker Kantek 2.

The flow test, designed to identify and address the potential drift of MFM units, will reinforce the traceability and integrity of such systems used by Singapore’s MFM-equipped bunker tankers for fuel custody transfer.

Several delegates from Russia including representatives from PJSC Lukoil who came to the Republic to learn about the use of MFMs for bunkering and in particular, its MFM verification maintenance programme, witnessed the trial, learned Manifold Times.

The importance of MFM verification

Sergey Tyubekin and Andrey Kurochkin, both Chiefs at the Department of Metrology and Standardization of PJSC Lukoil, respectively overseeing the oil major’s downstream and upstream operations explained the importance of MFM verification to the Singapore bunkering publication.

“MFMs can be used by both supplier and buyer for the custody transfer of oil products, including marine fuel,” said Tyubekin and Kurochkin in a joint statement.

“Meter Verification or Meter Proving is a recurring periodical confirmation of the measuring instrument’s [MFM] compliance with its established requirements, including accuracy indicators.

“With reduced measurement errors, information related to the product’s parameters is more reliable from a custody transfer point of view.”

In reality, determining the true value during measurements is more complex due to external operating conditions.

“Environmental conditions such as precipitation and ambient temperature, process/product conditions and/or construction design features such as wear out of certain parts, and more, can lead to increased measurement uncertainty during operation,” both explained.

“Meter Verification or Meter Proving of MFMs allow these systematic errors to be detected and eliminated or reduced to acceptable values.”

Depending on the company’s practices, MFMs being used for the transfer custody of oil products in Russia are returned to their respective re-calibration facilities at a frequency of between once a year to once every four years.

For example, the Lukoil company conducts additional Monitoring of Metrological Characteristics (MMCh) for its custody transfer MFMs once a quarter under different weather conditions (winter, spring, summer, autumn) in accordance to internal regulations.

“Such large interval between proving operations (confirmation of conformity) indicates the stability of the Coriolis measurement method and the trust in its measurement,” they stated.

Benefits of using the Coriolis Mass Flow Meter as a master meter

Tyubekin and Kurochkin further believed the use of a MFM master meter for verification offer advantages over other technologies such as the reference piston prover system currently used in Russia for verification of its MFMs.

“In my opinion, the mass flow master meter has some advantages over the piston prover due to its smaller dimensions. Therefore, it is easier to move between objects of verification,” they said.

“The verification process using MFM master meters are also faster, the units are cheaper to acquire when compared to piston provers, and the technology offers the possibility to compensate for viscosity effect.

“At the same time, using an MFM master meter allows proving under real operating conditions and the real oil product. Coriolis-based MFMs also encounter minimal wear and tear due to the lack of mechanical moving parts when compared with the piston prover.”

Sherman Lee, Marketing, Sentek Marine & Trading Pte Ltd, believes the master meter will be a “game changer” for the Singapore bunkering sector when officially introduced as it shortens the time and reduces resources required for bunker MFM verification.

“This represents quite a significant amount of cost saavings for operators in maintaining the system,” notes Lee, whose company owns the Kantek 2.

“With a master meter, the setup and completion in the verification of the duty meter [MFM installed on the barge used for custody measurement] should be done in less than a day and only involving one bunker tanker.

“Arguably, the most important aspect of this operation is the ability to trace the meter’s performance in meeting international metrology standards as differences in any MFM measurements will cost the company commercial losses.”

The master meter is scheduled to undergo further tests involving Singapore authorities during the next half of February before being approved for verification operations of duty MFMs installed on board Singapore bunker tankers due for yearly re-validation.

Singapore police arrest eight over alleged illegal MGO transaction off Tuas

The Singapore Police Force (SPF) on Thursday (13 August) said it has arrested eight men, aged between 25 and 54, for their suspected involvement in an illegal transaction of Marine Gas Oil (MGO).

On 13 August 2026 at about 1.05am, officers from the Police Coast Guard (PCG) conducted a check on a Singapore-registered tugboat in the waters off Tuas and discovered that eight crew members were possibly involved in the illegal transaction of MGO. 

“Preliminary investigations revealed that the crew members of the tugboats misappropriated MGO valued at about SGD 10,570 (USD 8,258), without their company’s knowledge,” SPF said in a statement.

“The MGO was sold illegally for their personal financial gain.”

The eight crew members will be charged in court on 14 August 2026 with the offence of theft by servant of property in possession of master under Section 381 of the Penal Code 1871 If convicted, they shall be punished with an imprisonment term that may extend to seven years and shall also be liable to fine.

“The Police take a serious view of illegal transaction of MGO in Singapore Territorial Waters and will continue to conduct enforcement and security checks to prevent, deter and detect such illicit activities in Singapore waters,” SPF added.

Gard: Sulphur-related bunker claims rise amid tighter China MSA enforcement

Claims involving excessive sulphur content in marine fuels have been rising, while stricter inspections by the China MSA have heightened the focus on sulphur compliance, particularly in the Bohai Sea.

Maritime protection and indemnity (P&I) club Gard on Wednesday (12 August) highlighted that claims involving excessive sulphur content in marine fuels have been rising, while stricter inspections by the China MSA have heightened the focus on sulphur compliance, particularly in the Bohai Sea:

Rise in off-spec sulphur claims

Recent claims experience indicates that bunker quality continues to pose a significant operational risk for shipowners. In our earlier review of bunker-related claims during the first five months of 2026, we highlighted a rise in off-specification bunker incidents amid increased pressure on global fuel supply chains following the escalation of the conflict in the Middle East. 

Specifically for Sulphur compliance, between January and June 2026, the number of sulphur-related cases increased by more than threefold compared with the same period in 2025. Notably, the number of cases recorded in the first six months of this year has already exceeded the total number reported during the whole of last year by approximately 40%. 

While each case is fact-specific, the increase is notable because excessive sulphur content constitutes a MARPOL compliance issue. Unlike many other bunker quality problems, sulphur non-compliance identified through port state inspections can result in vessel delays, enforcement action, and substantial costs associated with debunkering and fuel disposal. 

The map below illustrates the geographical distribution of sulphur-related claims recorded during the first six months of 2026, based on the location where the bunkers were stemmed.

China MSA steps up sulphur compliance enforcement

According to our correspondent, Huatai, on 5 June 2026, the maritime authorities of Tianjin, Hebei, Liaoning and Shandong jointly launched a special campaign on ship pollution prevention and control in the Bohai Sea region. The campaign involves coordinated supervision by local MSA branches across the region and is expected to last nearly five months. It covers major ports and surrounding port areas in the Bohai Sea region, including Tianjin, Tangshan, Qinhuangdao, Huanghua, Jinzhou, Yingkou and Longkou. 

While the initiative is broader than bunker sulphur compliance alone, its scope includes inspections relating to air pollution prevention, SOx emissions, fuel compliance and other high-pollution-risk operations. Enforcement measures are expected to comprise onboard inspections, cross-regional enforcement activities, unannounced spot checks and remote monitoring. These efforts will be supported by a combination of UAV patrols, maritime patrol vessels, shore-based monitoring systems and rapid on-site fuel testing. 

As a result, vessels trading in the Bohai Sea region may experience increased scrutiny of fuel compliance documentation, fuel sampling records, onboard fuel management procedures, and the handling or disposal of suspected non-compliant fuel.

Documents typically requested by China MSA

Based on our recent experience, including the case discussed above, and subject to the specific requirements of the local MSA office, owners and operators may be requested to provide supporting documentation such as: 

  • Bunker documentation – Bunker Delivery Notes (BDNs), MARPOL fuel sample records, fuel test reports, and relevant fuel quality certificates. 
  • Statutory certificates – including the International Air Pollution Prevention (IAPP) Certificate and International Oil Pollution Prevention (IOPP) Certificate. 
  • Operational records – engine logbooks, deck and navigation logbooks, Oil Record Book entries, and records relating to fuel transfers, storage and consumption. 
  • Sampling documentation – the Master’s statement and any records demonstrating how fuel samples were drawn, sealed, labelled, handled and retained. 
  • Correspondence records – communications with the authorities, bunker suppliers, charterers and other relevant stakeholders. 
  • Fuel disposal records – approved disposal plans, debunkering documentation, receipts and evidence of final disposal, where applicable. 

The exact documentation required will depend on the nature of the investigation, the findings of the inspection, and the requirements of the local enforcement authority. 

Possible regulatory consequences in China

Under the Air Pollution Prevention and Control Law of the People’s Republic of China, ocean-going vessels are required to use fuel oil meeting atmospheric pollutant control requirements after berthing. Vessels operating within designated emission control areas must also comply with applicable emission standards. Article 106 provides that where vessel fuel oil fails to meet applicable standards or requirements, the competent maritime authorities may impose fines ranging from RMB 10,000 to RMB 100,000. Liability may extend to shipowners, ship operators and ship managers depending upon the circumstances of the case. 

Recommendation

Sulphur compliance should be treated as both a fuel quality and regulatory risk. Owners and operators are encouraged to take preventive steps before bunkering, act promptly if non-compliant fuel is suspected, and preserve evidence carefully if an inspection or claim arises. Under amended 

Resolution A.1206(34), Appendix 18, 2.1.5, if the BDN shows compliant fuel, but the master has independent test results of the fuel oil sample taken by the ship during the bunkering which indicates non-compliance, the master may document this by notifying the ship’s flag Administration, with copies to: 

  • the competent authority of the relevant port of destination, 
  • the Administration under whose jurisdiction the bunker deliverer is located, 
  • and to the bunker deliverer.
