Even though maritime safety has improved a lot since ships started sailing the seven seas,a significant number of incidents occur yearly. Over the past decades,technologies such as AIS and Dual GNSS have made sailing significantly safer.However, until recently, the risk analysis tools have mainly consisted ofstatistical analysis of accident data, expert judgment, and the development ofgeometric route models or time-domain simulations (1). None of theaforementioned tools address the maritime risks in real-time while sailing.

Groke Technologies’ situational awareness system was developed to address the safety of sailing in real-time. On modernvessels, there is plenty of data available from multiple sources. Groke Procombines the data with real-time camera imagery and enriches the collected datawith AI and machine learning. One feature that elevates Groke Pro from a digital watchkeeper to an intelligent companion is the Real-time Risk Analysis. Risk analysis presents the crew with crucial real-time information about the vessel’s surroundings relative to nearby vessels. Based on the information available from the risk analysis, the captain and the supporting crew can make the best possible decisions onboard.

As Captain Jan Hanse says: “Risk compass is a really valuable tool in all congested traffic areas such as traffic separation zones. The risk compass gives users an immediate overview of the directions you can turn your vessel toavoid collisions.”

Riskanalysis consists of three components:

-         Risk compass

-         CPA points and alarms

-         Relative velocity tracking

Real-time risk analysis is one example of how Groke Pro converts data to safer sailing and improved crew welfare. Groke Pro was not designed to replace crew on board but to provide them with the best possible information to support their decision-making. With better decision-making comes improved safety. Improved safety in turn helps to increase crew welfare.
