Smart Buoyage: How IoT is Transforming Maritime Aids to Navigation Systems

For decades, the mission of maritime buoyage has remained unchanged: ensuring safe navigation routes and protecting maritime activities by clearly marking hazards at sea. However, in today’s digital era, a new transformation is underway. The Internet of Things (IoT) is fundamentally reshaping how buoys and beacons operate, are monitored, and interact. At GISMAN, we actively support this transition toward connected, more efficient, and more sustainable aids to navigation.

From Traditional Signaling to Smart Buoyage

Historically, maintaining operational performance of marine aids to navigation relied on inspections at sea and onshore, requiring significant human, nautical, and logistical resources.

Today, thanks to IoT, buoys are becoming intelligent and enable proactive management of marine aids to navigation. They can communicate their position in real time, along with their operational parameters, and can even transmit environmental and weather data when equipped with dedicated sensors.

How IoT is Transforming Maritime Buoyage

The integration of sensors and connected communication systems offers new possibilities:

• Remote monitoring: Operators can access equipment parameters in real time (position, battery charge status, light operating parameters, etc.) without the need to deploy vessels for on-site inspections.
• Predictive maintenance: Monitoring these parameters makes it possible to anticipate and optimize maintenance operations, reducing offshore interventions, costs, and environmental impact.
• Environmental and meteorological data collection: Buoys can be equipped with sensors and multiparameter probes to measure in real time ocean physicochemical properties, sea state, weather data, and underwater noise generated by offshore operations.
• Interoperability: Onboard systems can also transmit information to mariners, enhancing navigation safety (VTS, AIS).

IoT at GISMAN: An Integrated and Secure System

GISMAN’s range of marine signal lights integrates the latest IoT technologies to transmit data to a dedicated web portal through various communication options:

• Bluetooth® via internet from a smartphone
• Local mobile network (4G/5G) in covered areas
• Satellite communication for remote zones with no infrastructure
• AIS Transponder AIS (type 1 or type 3) via VHF

Data transmission is secured to ensure reliability and confidentiality.

A2NGO Monitoring Platform

All data can be accessed via GISMAN’s dedicated web platform:

• Real-time visualization of parameters and position of maritime signaling equipment (AtoN)
• Alert notifications in case of malfunction and maintenance planning

Benefits for the Maritime Community

IoT at sea brings decisive advantages:

• Optimized service availability of maritime buoyage through preventive maintenance.
• Reduced operational costs and environmental impact by limiting offshore operations.
• Enhanced safety of maritime activities through better knowledge of environmental and weather conditions in navigation areas.
• Improved understanding of marine ecosystems through underwater data collection.

Towards Sustainable and Connected Maritime Buoyage

Smart buoyage represents a new way of approaching maritime safety and sustainable ocean management. Thanks to IoT and robust communication systems, each buoy becomes an active component of the digital and ecological transition.

By placing innovation, connectivity, and eco-responsibility at the core of its solutions, GISMAN supports ports, maritime authorities, and local communities in their transition toward the buoyage of the future: connected, sustainable, and fully focused on ensuring safety for future generations.
