How We Adapted Offshore Wind Fog Signals
to Meet U.S. Coast Guard Requirements
A New Standard in Fog Signal Control
Traditionally, offshore wind fog signals are triggered by visibility meters. But when the U.S. Coast Guard introduced its new Mariner Radio Activated Sound System (MRASS) for federal fog signals, they wanted this technology integrated into offshore wind farms as well.
The Challenge
- Finding and vetting a reliable supplier
- Ensuring seamless integration with our fog signals and NAi system
- Designing a durable, offshore-ready housing
Our Solution
After thorough research and development, we created a compact 30×30 cm control unit, equipped with a UHF receiver and our I/O module. This unit could be easily mounted next to the fog signal for efficient operation.
The Impact
With the MRASS module in place, we now have a fully compliant system that integrates seamlessly with our existing technology. Most importantly, it meets the U.S. Coast Guard’s approval, paving the way for enhanced offshore fog signal control.
More Case Studies
Original NAi Product Line
Initially, our first offshore wind projects utilized components repurposed from other industries. This led to multiple interface requirements, increased engineering complexity, and minimal monitoring capabilities.
Integrating ADLS in Germany
In 2018, Germany passed a law requiring Aircraft Detection Lighting Systems (ADLS) for all onshore wind farms and certain offshore zones. This affected 19 offshore wind farms, necessitating compliance with the new regulations.
