Decision-optimised or overloaded? Rethinking the use of digital tools on a digitalised bridge
The bridge has never been more capable. It has also never been more complex.
75% of mariners report moderate to significant workload increases from GNSS disruption alone. The challenge is not a lack of information. It is whether that information is presented in a way that supports safe and effective decision-making.
The bridge is now part of a broader digital operating environment connecting navigation, compliance, performance management, emissions reporting, and shoreside oversight. The issue is that technology has often been added in layers, creating more systems, more alerts, more data, and more interactions for crews to manage.
When tools do not communicate effectively, crews become the link between them, interpreting conflicting information, moving between interfaces, validating system outputs. Operational resilience becomes dependent on individual experience rather than good system design.
Decision-optimised or Overloaded?, commissioned by OneOcean, explores why growing bridge complexity is creating new operational risks, and what decision-ready systems need to look like in practice.
