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.

Yang Ming orders six LNG dual-fuel, ammonia-ready containerships from Hanwha Ocean

Taiwanese shipping firm Yang Ming Marine Transport Corporation (Yang Ming) and South Korean shipbuilder Hanwha Ocean on Wednesday (2 September) signed a shipbuilding contract for six 13,000 TEU class LNG dual-fuel container vessels. 

The contract was signed by Dr. Chuck Tsai, Chairman of Yang Ming, and Mr. Charles Kim, CEO of Hanwha Ocean. The vessels are scheduled for delivery between 2028 and 2029. 

They will complement Yang Ming’s existing fleet of 10,000+ TEU vessels and serve as key vessels on East-West services, with deployment flexibility across trade lanes connecting Asia with the East and West Coasts of North America, South America, and the Mediterranean. 

Each of the six new vessels will have a capacity of up to 13,650 TEU and feature LNG dual-fuel propulsion and Ammonia Fuel Ready specifications.

“As Yang Ming transitions toward net-zero emissions, LNG provides a relatively mature and economically viable alternative fuel solution, capable of reducing greenhouse gas emissions by approximately 20%,” the company said. 

“At the same time, ammonia can serve as a carbon-free fuel by utilising converted LNG storage facilities, while offering relatively lower conversion costs and comparatively well-developed supply chains and infrastructure. The Ammonia Fuel Ready design will therefore provide Yang Ming with greater flexibility in responding to increasingly stringent international regulations on greenhouse gas emissions.”

In addition, the vessels will be equipped with Type B LNG fuel tanks with a design pressure of 1.0 bar to enhance the safety and efficiency of LNG operations, together with a range of energy-saving technologies, including Wind Shields, Rudder Bulbs, Pre-Swirl Stators, and Shore Power Systems. Smart ship technologies and cybersecurity protection features will also be incorporated to enhance operational efficiency, safety, and reliability while effectively reducing fuel consumption and greenhouse gas emissions.

Deliveries under Yang Ming’s next-generation fleet optimization plan commenced earlier this year. By 2030, a total of 24 new vessels are expected to enter service. 

This includes 18 LNG dual-fuel vessels—comprising five 15,500 TEU, seven 16,000 TEU, and the six 13,000 TEU vessels under this contract—alongside six 8,000 TEU methanol dual-fuel-ready ships.

LR, China’s MARIC unveil tanker concept ready for three future bunker fuels

Lloyd’s Register (LR) and the Marine Design and Research Institute of China (MARIC) on Thursday (3 September) have secured Approval in Principle (AiP) for a new 114,000 DWT product and crude oil tanker designed to accommodate future conversion to LNG, methanol or ammonia.

Announced at SMM 2026, the concept addresses one of the biggest investment challenges facing shipping today: the need to develop vessels and capabilities that can support a range of alternative fuel options and pathways as technologies, infrastructure and regulations evolve.

While LNG is already a mature fuel pathway, methanol and ammonia remain at an earlier stage of development, with questions around global fuel availability, infrastructure development, economics and long-term adoption.

The 114,000 DWT tanker concept has been designed as a product and crude oil carrier that can accommodate future conversion to LNG, methanol or ammonia as technologies, regulations and fuel supply chains mature. By incorporating conversion readiness at the design stage, the concept aims to reduce future retrofit complexity and provide owners with greater confidence when planning long-term fleet investments.

The design concept was reviewed against LR’s July 2026 class rules and regulations, including requirements relating to ships using gases and other low-flashpoint fuels, alongside relevant IACS Common Structural Rules for oil tankers. Final classification and statutory approval remain subject to full compliance with all applicable rules and regulations.

Theo Kourmpelis, Global Business Director for Tankers, Lloyd’s Register, said: “Shipowners are being asked to make major investment decisions today despite continued uncertainty around which fuels will dominate in the decades ahead. Alternative fuel solutions each offer potential pathways to compliance, but fuel infrastructure, regulation and economics continue to evolve at different speeds around the world.

“Designs that preserve flexibility will be critical in helping owners manage risk while preparing for multiple future scenarios.”

Si Nan, Marine & Offshore Marketing Department Vice Director, MARIC, said: “As the industry explores different decarbonisation pathways, shipowners need vessel designs that can adapt alongside technological and regulatory developments. This concept was developed specifically to provide greater fuel flexibility and long-term resilience, allowing owners to respond to changing market requirements without being locked into a single fuel strategy.

“Receiving Approval in Principle from Lloyd’s Register is an important milestone that validates the design concept and supports its future development.”

DNV: Alternative-fuelled vessel orders hit highest monthly level since October 2024

Latest data from classification society DNV’s Alternative Fuels Insight (AFI) platform alternative-fuelled vessel ordering was strong in August, with 52 new vessels added to the platform.

This is the highest monthly total since October 2024 and follows another active month in July, when 47 vessels were added to the database.

LNG-fuelled vessels accounted for the vast majority of August activity, with 46 orders recorded. The container segment led the way with 30 orders, while the car carrier segment contributed a further 12 LNG-fuelled vessels. In addition, four ethanol-fuelled bulk carriers and two hydrogen-powered bulk carriers were added during the month, as well as one LNG bunker vessel.

The strong summer performance marked a significant acceleration in ordering activity after a relatively slow start to the year. In total, 242 alternative-fuelled vessel orders have been placed in the first eight months of 2026, representing a 27% increase compared with the same period in 2025.

LNG remains the dominant fuel choice, accounting for 63% of all alternative-fuelled vessel orders registered so far this year. Container vessels represent the largest share of these LNG orders (59%), followed by car carriers (30%).

Jason Stefanatos, Global Decarbonization Director at DNV Maritime, said: “The past two months have been particularly strong for alternative-fuelled vessel ordering, with August recording the highest monthly total we’ve seen since October 2024. This has helped lift year-to-date orders to a level well above the same period last year.

“LNG remains the leading fuel choice, driven largely by activity in the container and car carrier segments. These sectors have been among the earliest adopters of alternative fuels, supported by predictable liner operations and increasing demand from cargo owners to reduce emissions across supply chains. 

“For many owners, LNG offers a combination of emissions reductions, fuel availability and future flexibility while the longer-term fuel landscape continues to evolve. 

“At the same time, the latest figures include orders for ethanol- and hydrogen-fuelled vessels, highlighting that owners continue to explore a range of decarbonization pathways. Different segments are making different fuel choices, but the overall level of activity demonstrates continued investment in lower-emission shipping.”
