Integr8 Fuels, the bunker trading and brokerage arm of Navig8, on Wednesday (14 September) shared with Manifold Times its first Bunker Quality Trends where it examines and compares likelihood of off specification issues across all commercial grades of bunkers and key ports. The following is a continuation of yesterday’s coverage of the report:
Integr8 Quality Index
The last 6 months have identified a generally improving picture for both VLSFO and HSFO, however, the back story is that the improvement is from historic lows of the Integr8 Fuels Quality Index in Q1 of 2022, a period that coincided with the start of the war in Ukraine, Russian sanctions and the spike in oil prices as can be seen from Figure 6 below which compares Brent crude against Quality Index.
At the time of writing and given the crack has narrowed only slightly and remains more than $600/MT, these challenges show no real sign of abatement so in the short to medium term we do not expect to see significant improvement in fuel quality or compliance.
Focus on VLSFO
In the last 180 days, 2.7 % of all VLSFO supplies tested outside of specification (and beyond 95% confidence limits) forlimits) for ISO 8217 table 2 parameters. The data identifies that the risk of Marpol compliance is significantly higher globally than HSFO at 0.8%, however, this does not tell the full story given the elevated risk of non-compliance noted around blending hubs.
Based on the cross section of off specifications, we can identify the hit-rates of high risk off specification matters such as Aluminium and Silicon and TSP 0.1% and 0.4% or between one and four supplies per thousand. Again, these risks are magnified in blending hubs rather than those areas with either simpler blending models or refined products available. Delving a little deeper, and more concerningly in the last 180 days, approximately two thirds of all off specification VLSFO occurrences are because of Sulphur, Water or TSP Issues with Sulphur alone accounting for almost one third of all off specs (Fig 11) and virtually all compliance matters.
From a global standpoint, VLSFO quality is seen to be good, however, significant regional variances can be noted, none more so than for Belgian and Dutch ports (or ARA) where receivers are at least 10 times more likely to receive a notification of a VLSFO above 0.50% than in Singapore, and more than five times more likely than the rest of the world. (Fig 12)
More worryingly, we notice trends within trends in the case of ARA when we drill down to individual supplier performance and, referring to one anonymized example below, we note that in the case of August 22 to date we have strong grounds to believe over 10% of all deliveries were non-compliant and over 30% of all samples potentially noncompliant. To conclude, four out of ten of all VLSFO deliveries may result in non-compliance when considering data related to this anonymous supplier in ARA. (Fig 13, next page)
At the other end of the spectrum, we can identify examples of suppliers with excellent sulphur compliance who, in the last three months do not have a single sample that exceeded 0.50%Wt. (Fig 14)
Many theories exist as to why some ARA suppliers have such poor quality data when we consider Sulphur, not least the difficulties of buying ex-wharf and the challenges of the fuel even arriving onto the barge with a Sulphur level of 0.50% or lower, given the reduction in Sulphur give-away from a blending perspective in recent months. It is entirely possible this may be due to cross contamination in jetty lines (with HSFO), but this may also be due to other practices onboard the barge.
Indeed upon investigation of the anonymous poor performing supplier referred to earlier, it was identified that several of their barges were moving storage in-between HSFO and VLSFO with the first delivery post a HSFO movement inevitably testing above 0.5%, no doubt due to the common deck lines (and /or sampling points) onboard the barge.
Example (Fig 15) – A Barge line contains 3 MT of HSFO clingage and a barge tank 200MT of VLSFO at 0.50% Sulphur. 200MT of VLSFO is then supplied.
It is also entirely possible that the fuel is compliant in such cases given the possibility of cross contamination within sample points, therefore it is essential to ensure that the sample is representative of the fuel supplied and that there is no cross contamination in the continuous drip sampler. However, best practice remains that unless double valve segregation and separate manifolds are available on board the delivering facility, supplying HSFO and VLSFO from the same barge would be considered a substantial risk to quality if identified.
Expanding on these trends but now considering other parameters, we can also identify similar trends also exist for TSP across ARA when compared to Singapore and other bunkering hubs when considering the likelihood of results testing within tolerance (95% confidence limits 0.11%Wt to 0.15%Wt Incl) or beyond 95% confidence (0.16Wt or higher) in the last 180 days.
The variance across bunker hubs is eye opening. In the case of Fig 16 we can see that we are as much as 26 times more likely to have an off specification incident in ARA compared to Singapore and still almost four times more likely than the second worse hub statistically in Houston.
Interestingly however, the selection of a supplier identified with less risk (based on data available) in ARA would virtually remove this risk entirely and drop the likelihood of a result testing at 0.16%wt or above to the same as Singapore and consequently better than many of the other bunkering hubs worldwide.

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.

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
LNG-fuelled vessels accounted for the vast majority of August activity while the strong summer performance marked a significant acceleration in ordering activity after a relatively slow start to the year.
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.”
