More Efficiency And Safety Through Nautical Seaway Analysis

By evaluating historical AIS data, the researchers at the CML have already determined exciting information and forecasts for the arrival times of seagoing ships in port. These AIS data, which have been mandatory since 2004 for the transmission of the most important master data and movement information of merchant ships and have been stored since 2010, can be used to determine arrival times more accurately than before. In addition to distance and speed, other infl uences such as current, weather and traffic conditions are also taken into account when determining the travel time.

On the basis of these results, scientists from the CML, together with the federal waterways and shipping administration (WSV) and the federal maritime and hydrographic agency (BSH), have investigated possibilities for automated nautical seaway analysis.

In the research project „TINA“ (Techniques for Interactive Nautical AIS Data Analysis), funded by the Federal Ministry of Transport and Digital Infrastructures (BMVI), correlations of maritime traffi c and environmental data were analyzed and possible potentials were estimated.

Four focal points were of most interest:

• The determination of movement patterns of ships in specific sea areas.

• The risk and safety assessment of different encounter situations of ships in narrow fairways.

• The anomaly detection of historical and current ship movements.

• The Impact of shipping on the environment. In addition, ship movements are correlated with meteorological and oceanographic data and their influence is analyzed.
