When it comes to safe marine operations, Aids to Navigation (AtoN) are essential. They help vessels enter harbours safely, avoid collisions, and navigate in poor conditions – especially in busy or low-visibility areas.
But many of these systems have been in place for decades, relying on older technologies such as incandescent lights, manual maintenance checks, and limited communication capabilities. As shipping demands increase and safety standards evolve, ports and harbours are upgrading their AtoNs by replacing older setups with smarter, more efficient alternatives.
Tideland Signal is at the forefront of this shift, offering reliable, marine-grade solutions designed for the realities of modern port operations, including digital monitoring, solar power and LED marine lanterns.
At Wellhead Electrical Supplies, we supply Tideland Signal products across the UK, helping ports upgrade old infrastructure with practical, future-ready systems.
Let’s take a closer look at what’s changing.
The Evolution of Marine Lanterns and Radar Beacons
Aids to Navigation have come a long way in recent years. Here are the key components transforming traditional systems:
LED lanterns replacing old incandescents
Traditional marine lanterns are power-hungry and rely on semi-regular lamp changes.
Modern Tideland Signal LED lanterns deliver greater visibility, longer lifespans, and reduced maintenance, making them a smart upgrade for busy ports.
Remote monitoring and digital control
Instead of sending someone out to manually check lights, remote monitoring now allows for faults and diagnostics to be managed from a central control centre. This cuts down on unnecessary site visits and keeps maintenance teams focused where they’re needed most.
Solar-powered systems for off-grid reliability
With integrated solar charging, AtoNs can run automatically, this is ideal for remote locations or sites with limited infrastructure. Tideland’s designs are built to withstand harsh environments with minimal upkeep.
Radar beacons (RACONs) to enhance vessel awareness
Radar beacons add a visible marker to a ship’s radar display, helping vessels pinpoint hazards or harbour entrances, even in fog or darkness. For a deeper dive into how RACONs function and why they’re vital to modern navigation, check out our blog on RACON beacons.
Tideland Smart Display (TSD) Nautical Sentry (Cloud Based Monitoring Software)
Originally formulated as an Aids to Navigation Monitoring Software, the TSD Nautical Sentry software has now grown into so much more. Using historical and live AIS data TSD now offers many more features, effectively making it a ‘lite’ VTS system. With this product, you can:
- Actively track ships entering your port/area. Monitor ships speed, bearing, and position to effectively guide them into the port.
- Monitor the AtoNs surrounding your port/asset with alerts or failures along with Met/Hydro functionality.
- Creation of events and virtual or synthetic AtoNs to notify vessels entering the port of obstructions or other warning areas.
- Send messages to oncoming vessels.
- Advanced recording and replay features of AtoNs and vessels within your port.
- Create reports depending on your assets needs for vessels, AtoNs or events.
TSD’s cloud based set up and minimal installation time and low costs make it a perfect solution for small harbours/mariners, offshore windfarms, or offshore oil & gas who want to monitor vessel traffic around their asset, set up Geofencing and automatic messages or alarms along with monitoring their Aids to Navigation equipment, all without the expensive outlay of a full VTS system.
Benefits of Modern Aids to Navigation for Ports and Harbours
Upgrading to digital AtoNs isn’t just about keeping pace with technology, it offers real operational benefits:
- Lower operational costs: Fewer site visits and longer-lasting parts mean reduced maintenance and lower OPEX.
- Improved safety: Better visibility, consistent signals, and real-time alerts all help to reduce risk.
- Simplified compliance: Systems built to meet IALA and IMO guidelines help ports stay compliant without unnecessary admin.
- Flexible, scalable upgrades: Modular systems make it easier to expand, adapt or upgrade as needs evolve.
Example Applications
Across different marine environments, Tideland Singal AtoN solutions are helping improve safety and efficiency. Ports are replacing traditional harbour entrance lights with solar-powered LED marine lanterns, enhancing visibility for incoming vessels and reducing the need for routine maintenance.
To minimise confusion from nearby coastal lighting, harbours are adopting GPS-synchronised flash patterns on breakwater lights, ensuring clear and distinct signals.
Even in remote locations such as island terminals, satellite-connected systems allow engineers to monitor and control navigation aids from the mainland. This eliminates costly site visits and enables faster response times.
