During the International Defence and Security Exhibition (Feindef) held in Madrid from 12-14 May, SAES and Arisnova presented an innovative solution that integrates artificial intelligence and sonar technology for the detection of underwater objects. This collaboration is part of the ePark+ project, aimed at enhancing maritime defence and security through realistic simulations.
The ePark+ project, developed by a consortium led by Navantia and including SAES and Arisnova, focuses on researching technologies for the maintenance of offshore wind farms using unmanned vehicles. SAES’s participation in this consortium, supported by the Ministry of Science and Innovation, highlights its expertise in underwater acoustic propagation and infrastructure surveillance through advanced systems.
During Feindef 2025, the two companies showcased the development of a 3D synthetic environment, created by Arisnova, which facilitates sonar simulation under realistic underwater conditions. This environment enables artificial intelligence training to improve the identification of objects such as mines and underwater debris. Javier Mármol Peñalver, President of SAES, remarked: “This project demonstrates the potential of technological collaboration to advance maritime security, employing techniques that allow the precise and efficient replication of complex scenarios.”
José Manuel Corral Alsina, Commercial Director of Arisnova, commented that “the 3D environment we have created simulates the seabed with all necessary elements and a moving submarine tasked with conducting detections.” This allows the replication of multiple scenarios and modification of weather conditions. From these scenarios, data can be generated and processed by artificial intelligence systems and other applications, facilitating their training and autonomous learning from simulated situations representative of the real environment. The goal is to produce data as close to reality as possible so that SAES’s sonar can process them as if it were engaging in a real mission.
SAES has provided its simulation expertise to guide Arisnova in constructing the environment, ensuring the simulator is adaptable to different use cases and optimised for sensor training and testing. Moreover, the implementation of detection algorithms based on artificial intelligence, trained with both real and simulated data, promises to significantly enhance detection capabilities.
The solution presented by SAES and Arisnova is not only aimed at the defence sector but also opens up new possibilities for civilian applications, such as the maintenance of underwater infrastructures and the protection of critical infrastructure. This collaboration exemplifies how dual-use technologies originating from the defence sector can be diversified to tackle challenges in civilian industries, representing a significant step towards a safer and more efficient future.
