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
last modified: 2016-09-30, PSames DNV GL - how digitalisation will drive ship safety
5
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
