A new report has identified that marine fuels, despite adhering to international ISO quality standards, are contributing to operational difficulties for ships. This finding suggests that current compliance metrics may not fully capture all factors critical for reliable engine performance and vessel operations.

For freight forwarders and operations managers, this situation implies a heightened risk of unexpected vessel delays due to engine issues or increased maintenance requirements. Such disruptions could impact schedule reliability and potentially lead to higher operational costs for carriers, which might eventually be passed on through freight rates or surcharges. It underscores the importance of robust fuel management and contingency planning in supply chains.
