COLLISION AVOIDANCE

Collisions with marine mammals are a growing problem for the shipping industry, and are intrinsically linked to the 3-4% increase in maritime traffic each year (WWF).

THE DIFFICULTY OF DETECTION

There are two types of detection to consider: surface target detection and sub-surface detection. While the former is particularly relevant to the detection of UFOs or logs, it has little to do with marine mammals, which are present on or below the surface. Today’s technology can detect targets on the surface, using radar, thermal cameras, AIS, but subsurface detection is more complex.

A COLLABORATION FOR PROGRESS

In 2021, the Class joined forces with Pôle Mer Bretagne Atlantique to launch a Call for Expressions of Interest, for innovative solutions to prevent collisions at sea. During 2022, a consortium of three entities was selected. Pixel sur Mer, Sea.Ai and Ensta Bretagne jointly proposed EXOS24 project. This focuses on three sensors: radar, AIS and SEA.AI technology and uses both optical and thermal sensors. The latter, coupled with artificial intelligence, is capable of detecting all floating objects, during either day and night, including those not detected by radar or AIS. The reliability of the information transmitted by each sensor is then translated into data fusion. The aim is to provide accurate and reliable information, by combining and exploiting the complementary nature of each sensor’s data.

LOOKING FORWARD

The final part of the project focuses on the challenge of automatic avoidance, based on advanced algorithms for calculating collision avoidance trajectories. The project will now focus on surface detection, in order to make the data fusion technology more reliable, based on already reliable sensors. Additional sensors, notably for underwater detection, could be added as technologies evolve. By 2028, the aim is to be able to equip all boats with such a system.

 

THE HAZARD REPORTING SYSTEM

The Hazard Reporting System (HRS) emerged from an observation: at sea, there was no ergonomic tool for sailors to report imminent danger directly and effectively. HRS and its “Hazard Button” technology concluded its development in January 2023 and began its tests during The Ocean Race of that year.

The aim of this new function, accessible on the Adrena and Expedition routing software, is to:

  • Increase vigilance by alerting competitors and race management to any subsequent risk
  • Collect data, which is then made available confidentially to scientists and organisations working on risk studies for racecourses
  • Raise awareness of the risk and its implications

The data collected by this function is ingested directly into a database called Marine Strike Log. This is the world’s most comprehensive database of data relating to sailing boats. The implementation of this strategy and reporting system has supported the establishment of a new standard across all offshore racing events and classes.

  • The HRS has been used during all the major IMOCA events since 2023: The Ocean Race, Transat Jacques Vabre, The Transat CIC, Transat Retour à la Base à la Base and Vendée Globe.

  • The project’s 2025 objective focuses on setting up a global and interconnected database. This will enable all marine reporting applications to receive data from other media and feed a common platform in collaboration with key players such as Whale Alert and the International Fund for Animal Welfare.
