The International Bunker Industry Association (IBIA) on Tuesday (13 June) released an article on IBIA and International Organization for Standardization (ISO) providing presentations followed by a Q&A to elaborate on the subjects covered in their joint paper: 

IBIA and ISO made a real impact at the IMO’s recent Maritime Safety Committee meeting, MSC 107 (31 May to 9 June), where we provided presentations followed by a Q&A session to elaborate on the subjects covered in our joint paper, MSC 107/6/4. It was a great opportunity to bring more clarity to long-running discussions on fuel oil safety at the IMO, and it was very well received by IMO delegates who found our session very informative.

In MSC 107/6/4, IBIA and ISO described why we would not recommend making the ISO 8217 standard mandatory (one of the proposals under discussion at MSC 107). Our paper also outlined test precision principles as per ISO 4259, and explained why it is considered unadvisable to regulate oil fuel parameters other than flashpoint due to uncertainties in establishing clear and consistent links between specific fuel parameters and the safety of ships.

Early on during MSC 107, on June 1, ISO and IBIA jointly held a session with the title “Understanding fuel oil quality – meet the experts” where we provided two presentations followed by a Q&A. IBIA’s Director and IMO Representative Unni Einemo introduced the panel of experts and moderated the Q&A.

First up, Timothy Wilson, Principal Consultant Engineer at Lloyd’s Register, provided key insights into the scope of ISO 8217. He explained how the primary objective of 8217 is to safeguard ships from operational issues, but that a fuel testing off-spec does not necessarily impose a significant risk for the ship. In fact, off-specs very rarely means that the fuel is “unusable” or “unsafe”, but requires the engineers to understand the capacity of the ship to handle and manage the fuel safely.

Sharing test data from LR FOBAS from so far in 2023, he said 98.02% of distillate marine fuels met ISO 8217 specifications when taking into account the ISO 4259 test method precision application for the receiving ship. For residual fuel grades, the corresponding figure was 97.37% of all samples.

The most common off-specs include viscosity, water and sulphur. Analysing the data more closely, Wilson said only around 0.25% of total global off-specs for residual marine fuel grades were regarded as potentially problematic or even unusable fuels due to either significant offspecs for flashpoint (0.03%), cat fines (0.04%), water content (0.06%) or total sediment (0.12%).

Wilson shared that the next edition of ISO 8217 will see changes regarding categorisation, fuel stability, biofuels/FAME content, and an update on chemical compounds and test methodologies, in particular for Organic Chlorides.

Next, Charlotte Røjgaard, VeriFuel Global Business Director, did a presentation explaining the complexities of identifying clear cause and effect when a fuel has met ISO 8217 specifications, but the ship experiences operational problems. In these cases, fuel testing agencies are known to use advanced GCMS testing to try to identify if there are chemical compounds present that may be the culprit. She described how in some cases, such investigative testing has been successful in narrowing down the cause(s), but in other cases there was no consensus among fuel testing agencies about which chemical(s) were to blame, if any.

One of the difficulties stems from testing agencies using in-house methods. They can produce very different analysis results when testing the same fuel, both with regards to which chemical compounds they detect, and at which concentrations. This makes it hard to make meaningful comparisons and draw clear conclusions.

Unless there has been an operational problem, fuels will mostly not be subjected to GCMS tests, but Røjgaard shared data indicating that some of the chemical species often pointed to as the culprit were often also found in fuels that had caused no known operational problems. She said more research is needed into building a better understanding of how common specific chemical compounds are, whether they are in fact problematic and if so at what concentrations, or if they perhaps only cause operational issues under very specific onboard conditions.

In addition to Wilson and Røjgaard, Jeroen de Vos, Head of Quality at Peninsula and an IBIA board member, joined the expert panel for the Q&A with IMO delegates. A former employee of DNVPS and VPS, he too has deep knowledge of fuel quality testing, and all three panellists are members of the of ISO TC28/SC4/WG6, the technical committee overseeing the revision of the ISO 8217 marine fuel quality standard.

There were plenty of questions and comments from IMO delegates during the Q&A. The message from the expert panel was to highlight the importance of transparency and sharing information in an objective and constructive way. Ship operators can help by documenting the onboard experience, to establish if specific problems can be clearly linked to a specific fuel batch. Suppliers can help by providing more clarity and traceability on the supply chain. Testing agencies can help by sharing data with engine makers, authorities and organisations like CIMAC, and working toward finding standardised test methods.

Wilson also noted all the good work that has been made available to the industry to provide guidance on dealing with fuel quality since the introduction of the 0.50% sulphur limit in 2020. This included the ISO PAS  23263: 2019, the IMO’s Ship Implementation Plan and other IMO guidelines, and the Joint Industry Guidance on the supply and use of 0.50%-sulphur marine fuel that was published in August 2019 (available on THIS LINK).

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.”
