Ship collisions are responsible for human casualties, environmental pollution, financial losses, and infrastructure damage. The EU-funded SafeNav project will develop and test a highly innovative digital collision prevention solution to reduce the probability of collisions, impact damage, and grounding, and increase safe navigation. The project will use data from advanced sensors and other sources to deliver faster, reliable real-time detection of other vessels, fixed installations, submerged/semi-submerged objects, and marine mammals, and an effective visual representation of the multi-source data. SafeNav will create a holistic decision support system (DSS) by designing collision avoidance algorithms built on multi-sensory data input from propriety (LADARTM sensor suite) and off-the-shelf sensors already installed on vessels.
