Areas where digitalisation will help improving ship safety

Creating new insights from data

Combining historic records from

multiple data sources to derive ship

and fleet insights

– Casualty data

– PSC and survey data

– Environmental and geo data

– Other ship-related data

– (Analysing ship movements)

Decision-making on-board

Aggregating data generated on-board

for decision-making

– Dynamic barrier management

Operational support

– Emergency response

– Remote assistance

(Autonomous ships)

Environmental and geo data help understanding loads

Combine AIS data and

weather information to

determine loads

Consequences are estimated

• threshold models – how

often defined limits were

exceeded

• engineering models –

combine ship model and

sea states to estimate eg

fatigue life

New areas of certification and standards

are opening up

Data management standards

Data and domain model standards

Sensors and sensor systems

Wireless networks

Data logging systems
