West of England has updated its Neptune Bunker Information database with fuel quality data covering April through September 2026. The findings reveal high rates of technical off-specification results for residual and low-sulphur marine fuels in major shipping hubs.
Why it matters
Understanding these fuel quality trends is essential for ship operators to mitigate engine damage and ensure compliance with international maritime standards. The prevalence of off-spec fuels highlights ongoing volatility in the marine supply chain.
Antwerp recorded a 46.2% technical off-specification rate for HFO, while Barcelona reported a 70.3% rate for ULSFO samples. Meanwhile, VLSFO sulphur off-spec levels reached 68.6% in Rotterdam and 58.9% in Antwerp.
The players
West of England
West of England is a maritime protection and indemnity insurance provider that maintains the Neptune Bunker Information database.
The details
Reported off-specification results include exceedances in density, viscosity, water content, and ash. ULSFO issues were largely attributed to pour point non-compliances, affecting operations in ports like Barcelona and Genoa.
Timeline
The updated data covers the period from April 2026 through September 2026.
Market Landscape
These findings reflect the broader operational challenges facing the shipping industry as it navigates complex fuel compliance mandates. This situation highlights how persistent technical inconsistencies can disrupt global shipping logistics and force increased reliance on quality monitoring systems.
Ship operators and procurement managers may face increased risks of engine damage and costly maintenance delays due to these fuel inconsistencies. Companies should prioritize testing protocols to verify bunker fuel quality before bunkering at affected international ports.
The takeaway
Operators must implement rigorous pre-bunkering fuel analysis to mitigate the risks posed by inconsistent quality. Maintaining high-standard internal testing remains the most effective safeguard against potential operational failures.
