The Lab, the independent laboratory facility opened by leading multi-disciplinary technical and scientific consultancy Brookes Bell, on Tuesday (9 August) released an article elaborating the greater importance of bunker fuel analysis today following a surge in bunker fuel quality issues in recent months: 

With rising fuel costs, supply chain disruptions resulting from the war in Ukraine, and the entry onto the market of sanction-breaking oil, fuel quality issues are becoming an increasing concern for vessel owners and operators. It’s an issue we’ve seen firsthand here at The Lab. As a result, bunker fuel oil analysis is becoming more important than ever.

The rise of bunker fuel oil quality issues 

It’s difficult to discern one specific reason as to why there has been a surge in bunker fuel quality issues in recent months. Certainly, the current geopolitical issues, supply chain disruptions and impacts on oil and gas producers detailed at the outset of this article won’t be helping matters.

One potential reason for the rise in bunker fuel oil quality issues could be the use of cheaper, possibly sub-standard blending components which render bunker fuel off-specification. We’ve also seen instances where insufficient clarity concerning the clauses of ISO 8217, which leads to confusion as to what levels of contaminants are ‘acceptable’.

The point is that, no matter how bunker fuel quality issues arise, the fact is that they are arising – and vessel owners and operators should be aware and prepared.

Bunker alerts

When these contaminated bunkers are identified, a bunker alert is issued by VPS – who continually monitor global fuel quality and fuel oil trends in various ports around the world.

It’s these bunker alerts which prove there has been a noticeable surge of contaminated bunkers onto the world market – with 60% more bunker alerts issued this year compared to last (note – VPS will issue a bunker alert when they have identified an off-spec parameter for three vessels within one week for the same port). 

Of the bunker alerts issued by VPS in 2022, these have covered eight different ports for nine different parameters. 

Some of these bunker alerts have been related to sizable incidents. Arguably the largest occurred in Singapore in March of this year, where chemically-contaminated bunker HSFO fuel was delivered to over 200 vessels. 

According to reports, this resulted in major operational problems for 80 vessels – which has resulted in ongoing litigation over claims for compensation.

Bunker testing and specifications

What’s perhaps most shocking about the large-scale bunker contamination outlined above, is the point that Singapore – as the world’s largest bunkering port – has rigid sample testing procedures, governed by the Singapore Code of Practice for Bunkering (SS 600).

What’s more, these testing procedures were developed by the Maritime and Port Authority of Singapore and the Technical Committee for Bunkering under the purview of the Singapore Chemical Industry Council.

According to reports, the contamination has its roots in ‘Estonian type oil shale’ and ‘US type fracked shale oil’, with the principal contaminants being styrene and phenol.

Even more concerning, the off-spec, contaminated bunkers were not detected by the ISO 8217 testing requirements. 

This is a crucially important point for vessel owners, operators and charterers to absorb – even bunkers which are compliant with ISO 8217, may in fact contain contaminants, which can result in significant operational difficulties, including engine and other component damage.

A note on biofuels

Contaminants from poor cutter stocks or bad (or deliberate) blending practices aren’t the only thing vessel owners need to worry about. 

With an increasing volume of biofuels making their way onto the open market we are seeing a rise in cases of microbial contamination – this is because the fatty acid methyl esters in biofuels are hygroscopic, meaning they attract and absorb moisture.

Should your vessels be using biofuels then, it’s vital that the fuel system is kept as clean and dry as possible.

The consequences of bunker contamination

It’s important not to understate the potential negative consequences of taking on off-spec bunker fuel. Although it can be possible to burn off contaminated fuel, this isn’t always possible depending on the level and type of contamination.

In the worst case scenarios, taking on off-spec bunker fuel can result in asset damage, such as piston ring failure, cylinder liner damage, the deterioration of rubber seals, the accretion of solids on cylinder heads, the failure of gaskets and more. All of which can result in significant costs to remediate.

Damage to critical components can also lead to severe secondary consequences such as loss of propulsion, placing both the ship and crew at risk. This can impact on the safety of other vessels which may be navigating nearby, risking collisions and even groundings.

As you can see, what may seem like a single incident can quickly compound into several more.

It pays to take bunker contamination seriously.

What’s the solution? 

If vessel operators must treat ISO 8217 with caution, what then is the solution? 

Whilst there is talk of overhauling ISO 8217 to bring about stricter testing to identify contaminants before they pass a vessel’s manifold, as well as discussions concerning a bunker supplier licensing scheme – vessel owners and operators are advised not to wait for these developments. 

Instead, prevention should be the order of the day.

Here at The Lab we strongly recommend a proactive approach to fuel management and testing. 

We can carry out the full range of ISO 8217 Table 2 testing, supplemented by gas chromatography – mass spectrometry analysis (GC-MS), fourier transform infrared spectroscopy (FTIR), cleanliness and compatibility testing, and more.

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.”
