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.

Coriolis flowmeter Proline Promass Q is the specialist for accurate measurement of cryogenic liquids like LNG

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.

Raman Rxn4 analyzer provides real-time and in situ gas 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.

2050 Marine Energy Owner Adrian Tolson to discuss global MFM adoption in webinar

International shipping association BIMCO will be organising a 15+15 webinar featuring 2050 Marine Energy Owner Adrian Tolson on Wednesday (12 June).

Early in 2024, Tolson published a White Paper arguing for the global adoption of calibrated mass flow meters (MFMs) in the bunkering industry. 

He argued that this progress will bring much-needed transparency to bunkering by generating accurate, real-time data for all stakeholders along the marine fuel supply chain. 

Describing the problems for the industry caused by inaccurate quantity measurement he sets out a number of remedial actions.

The paper recognises the success of Singapore’s MFM based bunker licensing system and proposes this as a template for regulators in other regions across the world. 

It calls on all supply chain participants to actively support MFM-based deliveries, promote transparency and encourage digitalisation in the long-term interests of the bunker industry and to help further the decarbonisation goals of the shipping industry. 

“This 15+15 will explore these ideas and assess if there is a chance for real progress,” BIMCO said on its website.

The 30-minute webinar, titled Getting what you pay for – a novel concept in bunkering? begins at 12:00 UTC.

The 15+15 weekly webinars are a 30-minute webinar which includes a 15-minute presentation followed by a 15-minute Q&A.

First SIMOPS methanol bunkering operation completed in Singapore

X-Press Feeders, Global Energy Trading Pte Ltd (GET), and PSA Singapore (PSA) have successfully completed the first simultaneous methanol bunkering and cargo operation (SIMOPS) in Singapore on Monday (27 May), according to the Maritime and Port Authority of Singapore. 

A X-Press Feeder container vessel on its maiden voyage from Asia to Europe was successfully refuelled with close to 300 metric tonnes (mt) of bio-methanol by GET, a MPA licensed bunker supplier, using MT KARA, a dedicated IMO type II chemical bunker tanker classified by Bureau Veritas and operated by Stellar Shipmanagement Services. 

The use of the mass flow metering (MFM) system for methanol, together with the use of digital bunkering, was also trialled during the SIMOPS. This follows the inaugural ship-to-containership methanol bunkering for the Laura Maersk in July 2023, and the successful ship-to-ship methanol bunkering of close to 1,340 metric tonnes of blended methanol for the Stena Prosperous on 24 May.

With these operations, the Port of Singapore is ready for commercial scale operations for shore-to-ship, ship-to-ship, and SIMOPS for methanol, and the same methodology is being followed for other new maritime fuels such as ammonia and hydrogen.

First SIMOPS methanol bunkering operation completed in Singapore

The SIMOPS was conducted at the new Tuas Port with the support of MPA, together with various government agencies and local research institutions. 

The methanol bunker fuel was supplied simultaneously while the container vessel was completing container moves. SIMOPS is the preferred mode of operation for container vessels to enhance operational efficiency. The cargo operation was carried out with the use of PSA’s double trolley quay cranes and automated guided vehicles at Tuas Port. The SIMOPS was completed in four hours. 

The ISCC-certified bio-methanol used for the SIMOPS was produced by OCI Global, a world-leading green methanol producer, and supplied via GET, a ISCC-certified supplier. The fuel was lifted at Vopak Penjuru Terminal, Singapore, which is a ISCC-certified storage facility for biofuels and methanol.

A Hazard Identification (HAZID) and Hazard and Operability Study (HAZOP) workshop was organised by MPA in the lead up to the SIMOPS. Adapting the experience from previous operations, participants from various government agencies, industry, and local research institutions, discussed potential risks and developed the corresponding prevention, control, and mitigation methods to address them. The bunkering plan was also discussed, and the various roles and responsibilities were clarified to ensure a coordinated cross-agency response in an event of an incident. To ensure all participants were familiar with the required procedures and safety measures, a tabletop exercise was also carried out with the relevant stakeholders after the workshop.

To ensure the safe conduct of the SIMOPS, MPA had worked closely with the bunkering stakeholders to ensure that crew members are competent and trained in handling methanol as a marine fuel and associated emergency responses. 

As part of the preparations for the methanol bunkering operations on 24 May and 27 May, the crew from Kara had also attended the MPA-approved training course for the handling of methanol as a fuel that was conducted by the Singapore Maritime Academy (SMA), which is part of the Marine Energy Training Facility (METF) announced at Singapore Maritime Week 2024. For new fuels such as methanol, ammonia and hydrogen, all crew are expected to undergo the new training.

Feedback from these initial batches will inform the course development by tripartite partners and our research community.

The Emergency Operations Centre set up at MPA’s Port Operations Control Centre monitored the operations, supported by a drone equipped with volatile organic compound detector and infrared camera to detect methanol leaks into the atmosphere and methanol flames in the event of an incident. MPA also worked with the Meteorological Service of Singapore to provide advance warning on lightning risk. Representatives from X-Press Feeders, GET, PSA, local research institutions, and other government agencies were also at the EOC as part of the emergency response team.

The methanol plume model, which was employed during the first methanol bunkering operation conducted in Singapore in July 2023, was enhanced to support the operation planning and incident response plan. The updated model incorporated specific SIMOPs parameters, including vessels’ structure, port configuration and infrastructure, and proximity of simultaneous activities being conducted during the SIMOPS. At steady state, the digital models will be used to support commercial scale operations in the Port of Singapore.

Following the completion of the world’s first ship-to-containership methanol bunkering in Singapore last year, MPA launched an expression of interest (EOI) for the supply of methanol as a marine fuel in Singapore. A total of 50 submissions from over 60 regional and international companies comprising energy companies, fuel suppliers, traders, bunker operators, and storage companies were received. The strong industry interest signals clear business confidence in Singapore as a key offtake location for methanol and provides strong indications that the industry is preparing for methanol bunker demand to scale up in the coming years. MPA will call for applications for a license to supply methanol blends as a marine fuel in Singapore before the end of the year.

MPA is currently developing the Technical Reference for methanol bunkering, which will include the framework to govern the use of MFM and digital bunkering for methanol. MPA will also study further enhancements for the IMO Type II chemical bunker tanker as part of its ongoing work to develop the methanol bunkering licensing framework and Port Limit Bunker Tanker requirements for methanol bunkering. Insights from the EOI submissions will also inform the development of the methanol bunkering regulatory framework to ensure the safe and efficient supply of methanol blends as a marine fuel in Singapore at a commercial scale.

MPA has implemented digital bunkering since 1 November 2023, making Singapore the first port in the world to commence end-to-end digital bunkering operations. As part of on-going enhancements to allow MPA-approved digital bunkering solutions to be compatible for use with the bunkering of new fuels, the digital bunkering trial conducted as part of the SIMOPs has demonstrated the ability to transmit the essential methanol bunkering information electronically to various stakeholders and MPA, enabling near real-time visibility of the bunker delivery process. The potential to fully digitalise the bunker delivery process, including the bunkering of new fuels, will lead to significant time and cost savings for the entire maritime community, and will be part of the licensing requirements.

MPA, together with 22 partners, including leading global marine engine manufacturers, will establish the METF which will collectively train over 10,000 seafarers and shore-based staff by the 2030s. The METF will be based on a decentralised network of training facilities based in Singapore. It will tap on partners’ assets and technologies to train the workforce on the safe handling, emergency response, and incident management involving future marine fuels such as methanol, ammonia and hydrogen.

Mr Teo Eng Dih, Chief Executive, MPA, said: “The successful execution of the SIMOPS is the outcome of many months of preparation for tripartite stakeholders to plan, prepare, and train to ensure the safety of the crew, port and vessel, while maintaining a high level of efficiency.”

“The learnings gained from these operations will help to further refine the various SOPs and safety measures.”

“We thank all our SIMOPS partners in helping to achieve this and we look forward to working with other like-minded partners, including on the use of digital bunkering and mass flow meter solutions, to operationalise the delivery of the new  marine fuels in Singapore.”

Mr Francis Goh, Chief Operating Officer at X-Press Feeders, said: "Today marks a historic milestone for both Singapore and the global maritime industry. Our vessel was not just the first to berth alongside here in Singapore and refuelled with green methanol, which reduces carbon emissions by 65% as compared to conventional marine fuel, but we were also the first in Singapore to achieve this while simultaneously loading and discharging cargo.”

“These achievements demonstrate Singapore's position at the forefront of the global maritime industry's transition to renewable fuels. By working together collaboratively, we can achieve even greater progress.”

Singapore reaches new milestone with methanol bunkering op of “Stena Prosperous”

The Maritime and Port Authority of Singapore (MPA) on Friday (24 May) said Singapore is one step closer to developing its full capability to deliver methanol bunkering at a commercial scale. 

Close to 1,340 metric tonnes (MT) of blended methanol was bunkered ship-to-ship on 24 May and there will be another operation for simultaneous methanol bunkering and cargo operations for a container vessel this week. These operations will also test the use of mass flow meters (MFM) and digital bunkering.  

The blended methanol, comprising 20% ISCC-certified  bio-methanol combined with conventional methanol, was supplied by Global Energy Trading Pte Ltd, a MPA-licensed bunker supplier, using MT KARA, a dedicated IMO type II chemical bunker tanker operated by Stellar Shipmanagement Services. 

The fuel was received by the newly christened 49,900 DWT IMO II MeMAX tanker, Stena Prosperous, commercially managed by Proman, a leading methanol producer. This operation, which was completed in 7 hours, follows from the world's first ship-to-containership methanol bunkering conducted earlier in Singapore in July 2023 for the Laura Maersk during which 300 MT of bio-methanol was bunkered.

The blended methanol was supplied by Proman’s marketing arm, Valenz, and lifted at Vopak Penjuru Terminal, Singapore.

The blended methanol is reported by Proman to deliver CO2e saving of 31% on a tank-to-wake  basis compared to the same voyage operated on Very Low Sulphur Fuel Oil (VLSFO). The use of blended methanol provides a pathway fuel for ships to meet GHG emissions limits required by Fuel EU Maritime for ships trading in the European Union and European Economic Area. 

The lifecycle emissions accounting framework is currently being discussed at the International Maritime Organization. The Maritime and Port Authority of Singapore (MPA) expects the relevant metrics for maritime fuels, including well-to-wake, tank-to-wake, to be measurable, reportable and verifiable, and that these should be made available and updated as more information from these operations are reviewed.

The MPA-licensed bunker tanker MT Kara meets the requirements under the IMO’s International Bulk Chemical Code for the construction and equipping of ships carrying dangerous chemicals in bulk and complies with the Standards for Port Limit Bunker Tankers. 

The vessel is equipped with twin screw propulsion and a bow thruster for better manoeuvrability. Kara is also fitted with an onboard mass flow metering system, a flow boom capable of transferring bunkering hoses between vessels, and a vapour recovery line. In addition, for the safe handling of chemical cargoes such as methanol, the vessel is fitted with nitrogen bottles supplying nitrogen gas for the purging and blow through of the bunker hoses. 

Nitrogen, given its inert and stable properties, was used to fill up the remaining vapour space once the cargo is loaded, a process known as nitrogen padding, to reduce flammability risk. Finally, the vessel is equipped with Quick Connect Quick Disconnect (QCDC) and Dry Breakaway Couplings (DBC) for both liquid and vapour hose systems, to minimise leakages and enable the quick and simple disconnection of hoses in an emergency. 

MPA will study further enhancements for such tankers as part of its ongoing work to develop the methanol bunkering licensing framework and Port Limit Bunker Tanker requirements for methanol bunkering. The Technical Reference  for methanol bunkering, currently being developed, will also include the framework to govern the use of MFM and digital bunkering for methanol bunkering, taking into consideration the data gathered during this and the following operation. 

In preparation for the bunkering operation, the risk assessment, bunkering plan and checklists were jointly prepared by all the parties involved to ensure a common understanding of the safety measures and emergency protocols. Clear roles and responsibilities were also established for each agency to ensure that the operations, and emergency response, were coordinated. 

The Emergency Operations Centre (EOC) set up at MPA’s Port Operations Control Centre monitored the operation, supported by a drone equipped with a volatile organic compound detector and an infrared camera to detect methanol leaks into the atmosphere and methanol flames in the event of an accidental leak. The methanol plume model, employed during the first methanol bunkering operation in July 2023, was updated to support the planning and incident response for this operation. 

As part of the training and safety preparations for the bunkering, the crew from Kara attended the MPA-approved training course for the handling of methanol as a fuel, conducted by the Singapore Maritime Academy (SMA). 

The training course, one of the first in the Asia Pacific, was launched in April 2024 and covers the operational and safety aspects of methanol bunkering operations. The course curriculum was developed by SMA according to the standards and requirements set by MPA, taking onboard the lessons learnt and best practices from the first methanol bunkering operation conducted in Singapore in July 2023. 

This is part of the operationalisation of the Maritime Energy Training Facility Initiative announced at the 2024 Singapore Maritime Week. 

Mr Teo Eng Dih, Chief Executive, MPA, said: “We continue to learn and enhance MaritimeSG’s ecosystem capabilities from each bunkering operation involving new maritime fuels, in terms of developing new supply chains, enhancing infrastructure support such as terminal facilities and bunker tankers, meeting seafarer training needs, setting standards for bunkering and testing our emergency response plans.

“We thank Proman, Global Energy Group and Stellar Shipmanagement for the successful ship-to-ship bunkering of close to 1,340 MT of blended methanol. Doing so safely and efficiently is an important step towards our support to the international maritime community and complements MPA’s earlier call for expression of interest for proposals to supply methanol as a marine bunker fuel at scale in Singapore.”

David Cassidy, Chief Executive of Proman, said: “The bunkering of this 20/80 green/conventional methanol blend on Stena Prosperous represents a further step forward for methanol as a marine fuel.”

“Its cleaner burning properties, and lower greenhouse gas emissions, delivers immediate cleaner air benefits and underlines the value of using methanol blends as part of a pathway fuel strategy to a lower emission future, while helping the shipping industry to meet decarbonisation goals.”

“We were delighted to undertake this bunkering operation in Singapore after the ship’s official naming ceremony and would like to thank all parties involved for the successful collaboration.”

Munee Chow, Group Business Manager of Global Energy Group, said: “To all participating partners and personnel: Congratulations for achieving this milestone.  Being a Singapore bunker supplier of more than 30 years, this marks a memorial moment for Global Energy on our efforts towards decarbonisation.”

Kelvin Kang, General Manager, Stellar Shipmanagement, said: “With the successful execution of this large-scale methanol loading and bunkering supply operation, we have gained a deeper understanding of its operational characteristics. This valuable insight will enable us to further enhance the efficiency and safety of methanol handling in future operations.”

Stena Prosperous was officially named on 23 May at a christening ceremony held at the Marina Bay Cruise Centre, Singapore. On departing Singapore, the vessel will take its cargo to the United States of America.
