The MFM manufacturer has developed a standardised LNG bunkering solution to provide the most accurate real-time metering of LNG transfers using MFMs.




Endress+Hauser unveils its new LNG bunker metering solution

Swiss-based mass flowmeter (MFM) manufacturer Endress+Hauser Group shared with Singapore-based bunkering publication on its new bunker metering system for liquefied natural gas (LNG): 

Every day, large quantities of hydrocarbons are transported, stored, treated, received, and finally sold to a wide variety of consumers in the marine industry. Bunker metering solutions ensure that the amount of hydrocarbons transferred is measured with the highest possible accuracy. At the same time, the use of LNG as a marine fuel has been increasing in recent years, especially since ship owners and operators are striving to comply with the latest emissions reduction regulations set by the IMO and EU. As a sulphur-free fuel, LNG is a cleaner alternative to traditional fossil fuels.

Standardised LNG bunker metering solution

The infrastructure for LNG bunkering is still developing, but it is growing rapidly as more ports and shipping companies adopt LNG as a marine fuel. Endress+Hauser now offers a standardised LNG bunker metering solution to provide the most accurate real-time metering of LNG transfers. This is supplemented by a variety of options to meet the needs of bunkering operations, maritime operators, and ship builders. The package consists of Proline Promass Coriolis MFMs (mass flowmeters), temperature and pressure sensors, Raman optical analyzers for LNG composition analysis and a regulatory-compliant monitoring system. It guarantees accurate metering of LNG and boil-off-gas (BOG) under cryogenic conditions.

When bunkering with LNG, determining its energy content poses a challenge due to the handling of cryogenic fluids at extremely low temperatures of –160 °C (–256 °F). In addition, the LNG composition often varies due to mixing from different sources and ageing under storage conditions. Providing reliable measurement of the quality of the material transferred is an essential component in the LNG bunker delivery transaction. It is also essential for maintaining safe marine operations.

Analysis in situ and in real time

Gas chromatography (GC) has typically been used to measure the composition of LNG. However, gas chromatographs require that LNG be vaporised and the gas pressure regulated prior to analysis. Vaporizers normally demand frequent downtimes for maintenance to avoid incomplete vaporisation or pre-vaporization. The new solution from Endress+Hauser provides equivalent LNG measurement accuracy with significantly lower operating costs and requires less technical expertise. Furthermore, it has by far the smallest footprint compared to traditional systems. In addition, it is the only one on the market today that can analyse LNG in situ and in real time with our patented Raman technology. 

Powerful process analytical tools

Raman Rxn-41 probe enables direct insertion for composition measurement

Raman spectroscopy not only reduces the complexity of the LNG monitoring system and has faster start-up stabilisation times, but it proves to be more repeatable, responds more quickly to process changes and requires no maintenance throughout the assessment period. It uses a laser to produce light at visible or near-infrared wavelengths and a Raman analyzer looks for specific wavelengths and intensities to create a chemical profile of the sample. The combination of a Raman Rxn-41 probe and a Raman Rxn4 analyzer results in a powerful process analytical tool for real-time composition analysis of LNG and mixed refrigerants, using quantitative Raman spectral analysis.

The Raman Rxn4 analyzer is essentially immune to LNG flow variations and configurable with up to four probes for multiple location analysis. The Rxn-41 probe is a rugged insertion probe designed to be inserted directly into the LNG stream so that it takes the reading in situ, with the moving liquid constantly refreshing the sample. The two components are fully integrated into the LNG bunkering solution to provide customers with a complete system from a single vendor with the lowest OPEX of any solution on the market today.

Outstanding measuring accuracy

Another key component of the package is Proline Promass Q. The Coriolis MFM is designed as a specialist for accurate measurement of cryogenic liquids like LNG. Its incredible temperature stability results in best possible accuracy of the measured quantity, especially under cryogenic conditions. Thanks to its revolutionary 4-tube technology and an extended measuring range for sizes up to DN 250 (10"), customers benefit from low pressure loss and outstanding measuring accuracy (±0.35% mass) for both minimal and very high flow rates. The reduced pressure loss also avoids unwanted cavitation effects or gas breakout. 

The innovative meter design combined with our patented MFT (Multi-Frequency Technology) helps to reduce errors from entrained gas. Promass Q offers additional features like integrated Heartbeat Technology, which provides the onboard diagnostics and verification that enhance product and process safety. The complete sensor of the flowmeter, including measuring tubes and electronics, can be verified without interrupting the process by the push of a button, even from the control room.

China: First upgraded Zhoushan bunkering vessel completes inaugural refuelling op

“Dong Fang Zhao Yang” supplied 500 metric tonnes (mt) of heavy oil, 100 mt of light oil, and 81 barrels of lube oil to the “Emerald Liuheng” ship owned by Zhejiang Xinyi Shipping Co., Ltd.





China launches version 2.0 of “Zhoushan ship type” bunkering vessel

The first bunkering vessel of the "Zhoushan Ship Type" version 2.0 on Friday (12 January) successfully completed its inaugural refuelling operation at the anchorage outside Cosco Zhoushan’s Liuheng Shipyard after it was launched recently.

Dong Fang Zhao Yang supplied 500 metric tonnes (mt) of high sulphur fuel oil, 100 mt of low sulphur fuel oil, and 81 barrels of lube oil to the Emerald Liuheng ship owned by Zhejiang Xinyihai Shipping Co Ltd. The milestone marked an integrated comprehensive bunkering operation and meeting its “one ship with multiple functions” objective. 

According to media reports, the vessel uses a variable frequency cargo oil pump and an Emerson mass flow meter (MFM) bunkering system, which ensures accurate measurements of bunker fuel supplied.

Before the inaugural operation, shipowner Zhejiang Free Trade Zone Orient Shipmate Maritime Service Co Ltd worked with its partner Sinopec Fuel Oil Sales to strengthen cooperation with the relevant departments of various industries, formulate operation plans in advance and complete relevant procedures to ensure a smooth operation. 

Manifold Times previously reported the launch of Dong Fang Zhao Yang when it set sail for its maiden voyage at the Zhoushan Hetai Shipyard on 28 December.

Compared to the 1.0 version, the ship underwent six major upgrades including being equipped with twin engines, twin propellers and twin rudders to improve the ship's manoeuvrability and rotation, and significantly improves the ship's berthing capability.

Metcore: Taking the right approach in using MFM

It is a welcome development that global ports have started implementation of mass flow metering system (MFM system) for bunker fuel measurement. Although there are existing regulations for use of mass flow meters for general custody transfer purposes, they are not well enacted for the bunker fuel application. The critical difference is the approach in system set-up and onsite verification prior to custody transfer measurement, as well as the monitoring and control when the MFM system is in operation.






Mass flow meter (MFM) vendors today have taken steps to build their measurement system for bunker application; in-line with the encouraging results from the Singapore market which initiated the mandated use of mass flow meter (MFM) for bunker fuel measurement. However, the international marine refuelling sector, with the exception of Singapore, is still encountering bunker buyers not readily accepting the meter quantity as final and binding.

“The bunker buying culture of ‘trust’ will need to be far more convincing for buyers to accept the delivery figure from MFM-equipped bunkering vessels,” opines Darrick Pang, Managing Director of Metcore International Pte Ltd, a leading marine solutions provider with technical expertise in MFM systems for bunker applications based in Singapore.

“MFMs for bunkering are not plug-and-play systems because they require a large investment for the initial set-up and needs to be maintained regularly. Nevertheless, the success of transparency brought by the MFM system - without a doubt - can be seen in Singapore.”

“Till today, the international bunker trade is still encountering measurement comparison between the delivery bunker tanker and the receiving vessel. It is time for the delivery vessel to build trust while reducing unnecessary downtime in handling disputes.”

“The approach to MFM usage is more important than merely mandating its use because having a half-done initial certification will not do justice to the capability of the MFM system and the high costs of investment. It is as good as remaining status quo in using the conventional measurement method, since it defeats the purpose of ensuring trust and transparency of installing the MFM on-board the bunker takers for bunker fuel measurement.”

Enhanced Trust and Impartiality

The Singapore-based MFM system measurement solutions provider told Manifold Times it welcomed the development of more global key ports mandating use of MFMs that are trusted by international bunker buyers and shipowners alike.

It is crucial for interested stakeholders to tap onto the recognised ISO 22192:2021 'Bunkering of marine fuel using the Coriolis mass flow meter (MFM) system’.  Otherwise, the global bunkering sector may run the risk of evaluating the MFM system based on misaligned practices and operating disparate standards at different international ports.

“Existing national or regional legislations may not provide adequate guidelines on system performance testing. Moreover, the effect on metering for each installed system usually differs during the tanker’s delivery operations,” explained Pang.

“The situation calls for a two-pronged approach: firstly, to level-up with ISO 22192 guidelines, specifically the onsite verification requirements, and secondly, to have an independent and third-party conformity assessment body (CAB) to perform on-site verification on the MFM system in its operating conditions, to maintain impartiality.”


Support of Independent Third-Party Accredited CAB

“The support of an independent third-party accredited conformity assessment body (CAB) to safeguard the impartiality of evaluation and system testing activities at the specific vessel’s own operational level will ensure meter integrity,” believes Pang.

“Having a recognised third party’s independent certification, with reference to recognised and globally accepted standards, with an on-site MFM system verification prior to approval, as well as continual operation monitoring and regular control checks, will go a long way to ensure that the MFM system has the full functionality to provide accurate and trusted bunker measurements as a safeguard against potential disputes.”

Besides having the capability to evaluate the MFM and its associated devices, the CABs would endeavour to have in-depth knowledge of the bunker tankers cargo system set-up and bunkering operations to ensure comprehensive conformity to the relevant guidelines and legislated requirements.

The conformity assessment tests for optimal operational maintenance of the MFM systems for bunkering applications enhance trust and traceability for all stakeholders. This approach also provides a balanced view with representations from the various stakeholders without permitting any one interest to predominate. This will steer the maritime industry towards harmonised conformance framework and digitalisation across global ports.

Digitalisation for Transparency and Traceability

“It is more relevant than ever for bunker measurement practices to be harmonised for transparency and traceability across global ports,” explained Daryl Lim, Quality Manager of Metcore International Pte Ltd.

Lim was among the panel of speakers at ARACON 2023 and discussed with conference delegates from the marine fuel industry about various issues related to the certification of MFM Systems for bunker applications as well as the direction of bunkering to enhance trust and transparency.  He shared the experience of using MFM systems for bunker applications with reference to ISO 22192.


“Moving forward, harmonising of practices using standards with competent and independent conformity assessment approach would enhance trust, transparency and traceability when using the adequately certified MFM system for measurement of bunker fuel; especially in operations requiring continuous reliance on the latest technology in the measurement of marine fuel,” opined Lim

“Supported by the recognised third party’s independent certification, on-site MFM system verification and regular monitoring of operational controls - all these best practices for digitalisation will serve to strengthen the trust and acceptance of the MFM system’s measurement,” concluded Pang.
