CM Technologies Warns of Systemic Bunker Fuel Quality Failures Across Key Ports
German marine fuel testing specialist CM Technologies (CMT) has issued a formal advisory urging shipowners, operators, and chief engineers to implement rigorous fuel quality monitoring protocols in response to a surge in off-specification bunkers at major global hubs.
The warning follows a series of high-profile incidents where fuel samples have failed critical stability, viscosity, and contamination tests—posing immediate operational risks to engines and compliance exposure under MARPOL Annex VI.
Key Concerns Highlighted
- Catastrophic Stability Failures: Multiple reports indicate fuel separating prematurely in tanks, risking sludge buildup and filter blockages.
- Viscosity Variability: Significant deviations from specified grades, increasing wear on fuel pumps and injectors.
- Contamination Spikes: Elevated levels of water, sediment, and particulate matter detected in bunkers from European, Asian, and Middle Eastern ports.
CMT emphasizes that these issues extend beyond isolated incidents, suggesting systemic supply chain vulnerabilities. The firm recommends:
- Immediate laboratory testing of all incoming bunkers, with particular focus on ASTM D4176 and ISO 8217 compliance.
- Deployment of real-time in-tank monitoring systems to detect early signs of degradation.
- Documentation of all quality disputes for potential claims under ISO 8217 Clause 1 and BIMCO’s SUPPLYTIME 2017.
- Collaboration with suppliers to trace contaminated batches and verify supplier quality assurance processes.
Operators are advised to prioritize bunkering from suppliers with verifiable track records and to maintain contingency plans for alternative fuel sources in high-risk ports.
