NorthStandard has published the first data-driven benchmark of ECDIS proficiency, revealing widespread knowledge gaps among bridge teams despite years of industry focus on training.

The ‘Learning from the Data’ report draws on more than 5,000 assessments from the insurer’s ETA platform, developed with the UK Hydrographic Office. It provides an unprecedented snapshot of how crews actually use electronic chart display and information systems in practice.

The findings show that two-thirds of bridge teams could not identify ENC updates, while nearly half failed to prioritise the correct ENC scale during passage planning. Crews also struggled with alarms versus alerts, datum issues and key safety settings.

“ECDIS is a powerful tool… however, improper use can lead to alarms and indications not functioning as expected – and ultimately navigational errors,” said Tom Mellor of the UKHO.

With the transition to S-100 standards approaching, improving real-world ECDIS proficiency is likely to become a critical priority for safe and compliant operations.
