Steve Bee, Group Marketing and Strategic Projects Director of marine fuels testing company VPS, on Thursday (10 April) highlighted how proactive chemical screening can help ship operators avoid costly engine damages and legal claims that could take years to resolve: 

Over the past six years a number of high-profile, chemical-contamination cases relating to marine fuel have been witnessed. Hundreds of vessels have experienced costly engine damages during these events, for example, Houston (2018 and 2023), Europe (2022) and also in Singapore (2022). In addition to these highly publicised contamination events, there have been many single cases of vessel damage across the world, due to the presence of chemical contaminants within fuel. All of these cases, large or small, have shown numerous different chemical contaminants, or combinations of contaminants, which have been identified as being responsible for these damages.

VPS is at the forefront of vessel protection in relation to detecting chemical contaminants in fuel and as such, protecting its customers, assets and crew, as well as wider environmental protection. On numerous occasions, such cases result in legal action, where fuel quality testing and the resulting laboratory findings, provide key evidence in support of such claims. However, the wheels of justice turn slowly and it can be years before such claims reach a successful judicial outcome and are finally settled.

One example relating to such cases occurred back in 2023, where one claim is only just being tried in a court of law, two years later. VPS initially informed its customers via a Bunker Alert, of the presence of Dicyclopentadiene (DCPD) isomers at significantly high levels within VLSFO bunker fuel delivered in Houston. The contaminants were detected using in-house GC-MS (Gas Chromatography – Mass Spectrometer) analytical methodologies.

However, 14 vessels suffered serious levels of damage due to the presence of DCPD, in the form of:

  • Dihydro dicyclopentadiene (CAS No. 4488-57-7) 
  • Tetra-hydro dicyclopentadiene (CAS No. 6004-38-2)

Whilst it’s not uncommon to find cyclopentadiene, dicyclopentadiene, dihydro-DCPD, or tetrahydro-DCPD in some fuels, as they’re known to originate from ethylene cracker residue in a refinery. However, the major contaminants in this case were hydronated DCPDs, which can polymerise and oxidise under certain conditions.

Almost 20,000 ppm (2%) was the maximum concentrations detected of combined Di & Tetra Dicyclopentadiene.

The issues reported were mainly in auxiliary engines and consisted of:

  • Fuel leakage in the Injection Control Unit (ICU)
  • Fuel pumps unable to develop the required pressure:

Purifiers unable to remove cat-fines giving rise to high cat-fines at the purifier outlet

Sludge formation and filter blockages:

VPS did not record any particular engine type being more susceptible than others.

Risks from chemical contamination of fuel can be significantly mitigated through pre-burn screening of fuels using the VPS Chemical Screening Service. This low-cost test, utilising Gas Chromatography Mass Spectrometry (GCMS) analysis, will warn of the presence of over 75% of all volatile chemicals within fuel.

Focusing specifically on this as a damage prevention service, over 20% of applicable marine fuel samples received by VPS undertake this rapid, pre-burn protection service, with an average 8% of samples tested, giving rise to a “Caution” result, indicating the presence of at least one chemical contaminant and thus the notified vessel has avoided any damages and placed the supplier on notice, within the agreed time-bar, pending further investigation. All of which saves time and money, in relation to engine damage, lost operation time, costly spares, plus the lengthy expensive, time-consuming, claims process, which can follow when having burnt contaminated fuel.

Now VPS has further improved it’s chemical screening power, by developing a unique and highly innovative GCMS-Headspace Screening method, which not only detects volatile organic chemicals (VOCs), but also, semi-volatile organic chemicals (SVOCs) and non-volatile organic chemicals (NVOCs). A further paper covering this specific new method, will follow this article.

A single GCMS-HS screening test to check for the presence of contaminating chemicals within that one fuel delivery, can equate to less than 0.01% of the cost of a 1,000mt stem of fuel. Yet this service will provide a much greater level of protection to the vessel and avoid the risks of damage claims, associated with such chemicals within marine fuel.  Which raises the question, can you afford not to screen your fuel for chemicals?

VPS strengthens China presence with new Shanghai marine fuel testing facility

Marine fuels testing company VPS on Tuesday (1 July) announced the opening of its brand new testing laboratory in Shanghai, China.

The company said this strategic investment strengthens VPS’ global laboratory network and reinforces the company’s commitment to delivering faster, locally-based testing services to customers operating in one of the world’s most important maritime markets. 

“Shanghai has emerged as one of the fastest growing marine bunkering hubs and is expected to play a major role in the future supply of both traditional fossil fuels and emerging low-to-zero carbon fuels,” it said in a statement. 

“The new Shanghai laboratory will provide comprehensive marine fuel testing services, enabling customers to benefit from further improved turnaround times and enhanced operational decision making.”

The facility will support vessel owners, operators, charterers and fuel suppliers, with rapid, independent analysis and technical expertise, helping stakeholders to manage fuel quality risks, protect assets and maintain regulatory compliance.

Dr. Malcolm Cooper, CEO at VPS, said: “VPS is pleased to announce the opening of our new Shanghai Laboratory, which will provide fuel quality testing for bunker fuels including methanol. China is central to the global shipping industry being the world’s largest shipbuilder, producer of shipping containers and operator of the biggest commercial fleet. Shanghai is therefore the perfect home for our latest laboratory, as VPS is the world’s leading fuel testing company”.

The investment comes as marine fuel volumes in Chinese ports continue to grow and customers increasingly demand faster testing and advisory services. The new facility further enhances the VPS global footprint, which already includes laboratories in Rotterdam, Singapore, Fujairah, Houston and Manchester, supported by an international team of technical experts, sales professionals and customer service specialists.

In addition to supporting conventional marine fuels, the Shanghai laboratory will provide testing and advisory services relevant to the industry’s growing adoption of low-to-zero carbon fuels, assisting customers to navigate emerging fuel quality performance and compliance challenges.

Andrew Morton, VPS MD-AMEA, stated: “The opening of our new laboratory in Shanghai’s Lingang New Area, positions VPS at the heart of one of China’s most important maritime and industrial growth hubs. This investment reflects our confidence in the Chinese maritime market, our commitment to supporting customers closer to where they operate and our belief that Asia will remain at the forefront of shipping’s energy transition.”

The Shanghai laboratory will serve both domestic and international customers operating throughout China and across the wider Asia-Pacific region, supporting ongoing growth in marine fuel testing demand and providing a platform for future expansion of VPS services within the Chinese maritime sector.

BV enters exclusive talks to sell fuel testing business to Triton Partners

Classification society Bureau Veritas (BV) on Tuesday (30 June) announced that it has entered exclusive negotiations with Triton Partners regarding the sale of its Oil & Petrochemicals and Coal testing and inspection business, BVF. 

This strategic divestment is in full alignment with the Group’s LEAP | 28 strategy.

The proposed transaction would include the Oil & Petrochemicals and Coal testing and inspection activities. In 2025, this business generated approximately EUR 450 million in revenue operating a global network across multiple countries, with a significant footprint of operational sites and employees. 

This business grew at a lower rate than the Group and is margin dilutive. It is included within Bureau Veritas’ “Optimize value and impact” portfolio and reported under the Agri-Food & Commodities division. 

“The transaction supports the strategic objective to increase exposure to higher growth and margin businesses,” BV said.  

This transaction represents a significant milestone in Bureau Veritas’ portfolio transformation. Following completion and taking into account other recent acquisitions year-to-date, the Group will have executed approximately 20% portfolio rotation since the launch of LEAP | 28. 

“This divestment is fully aligned with our LEAP | 28 strategy and our commitment to actively manage our portfolio,” said Hinda Gharbi, Chief Executive Officer of Bureau Veritas. 

“The Oil & Petrochemicals and Coal business operates in established and mature markets, and is led by a global team. Under the leadership of Triton Partners, we are confident that this business will continue to develop successfully. This transaction will create shareholders value as Bureau Veritas accelerates its planned portfolio pivots towards higher growth and higher margin activities.” 

The transaction, based on an enterprise value of EUR 470 million, implies an EV/EBIT multiple of 11.1x on 2025 results post IFRS16. The disposal will have a positive impact on the Group’s organic growth profile, adjusted operating margin and return on capital employed. The deal is anticipated to be broadly neutral to earnings after closing. 

Bureau Veritas intends to redeploy the proceeds towards higher-growth and higher-margin businesses, in line with LEAP I 28 portfolio ambitions.

Bunker Fuel Quality

Fuel quality issues drive 50% rise in bunker claims, says Gard

Gard says bunker-related claims increased significantly in between January and May 2026, with over 70 cases recorded – a 50% rise compared to 2025 and notes that most claims involve fuel quality.

Maritime protection and indemnity (P&I) club Gard on Friday (19 June) released a report on practical observations from recent cases of bunker-related claims, highlighting recurring challenges and essential considerations for managing fuel quality issues effectively:

Key findings

  • Sharp rise in bunker claims and geopolitics: Bunker-related claims increased significantly in early 2026, with over 70 cases recorded – a 50% rise compared to 2025. Most claims involved fuel quality, with a noticeable uptick following the escalation of the Middle East conflict.
  • Global risk profile with concentration driven by supply volumes: Bunker quality incidents were recorded worldwide, reflecting a broadly dispersed and global risk environment rather than a localized issue. Higher numbers of claims at major hubs such as Singapore, Houston, and ARA mainly reflect their large bunkering volumes
  • VLSFO remains the primary source of claims: Very Low Sulphur Fuel Oil (VLSFO) accounts for the vast majority of bunker quality claims. Its complex blended nature increases the likelihood of variability and contamination, making it more prone to quality issues. This reinforces that VLSFO continues to be the key technical risk area in marine fuel usage.
  • ISO 8217 compliance does not guarantee fuel suitability: A significant proportion of cases involved fuels that met ISO 8217 Table 2 parameters but still caused operational issues and damage to machinery. This underscores the growing importance of Clause 5, which focuses on whether fuel is fit for use and free from harmful substances. Standard testing alone is often insufficient, requiring more advanced analysis to identify problematic contaminants.
  • Claims are driven by both technical and contractual challenges: Bunker disputes are often complex due to misaligned contractual relationships between owners, charterers, and suppliers. Issues related to binding sample, parameter(s) to be tested, time bars and evidentiary requirements frequently complicate claims resolution.
  • Operational impact is often underestimated compared to headline casualties: While no major casualties were directly linked to poor fuel in this dataset, several vessels were disabled or required towage. These incidents can create high exposure when occurring in congested or coastal waters. The absence of catastrophic outcomes should not obscure the underlying operational risk.

This report draws on Gard’s claims data from the first five months of 2026, with additional data contributions from VPS.
