Japanese Yellow
Lantern Adaption

Adapting Marine Lanterns for Japanese Offshore Wind
In Japan, marine lantern housings must match the color of the emitted light.
This presented a unique regulatory requirement that differed from industry standards.

 

 

The Challenges

We identified four primary engineering challenges:

Environmental Durability
Components needed to withstand saltwater, extreme weather, and mechanical stress.

Remote Monitoring & Control
A centralized system was required to ensure real-time oversight and adjustments.

Installation Efficiency
Components had to be simple, self-testing, and easy to install to reduce labor costs.

Scalability
The system needed to support thousands of interconnected components without excessive engineering effort.

The Search for an Answer

We tested various coatings and materials—paint, anodizing, and foil. Each had drawbacks, but after rigorous trials, we found the perfect solution: a durable foil sleeve. We then consulted with the Japanese Coast Guard to ensure that they were happy with this solution and received their approval. 

Results

Benefits
  • Maintained existing mounting brackets and installation methods
  • Added an extra layer of corrosion protection
  • Provided a compliant, long-lasting solution

A Landmark Achievement
Thanks to our flexibility and ingenuity, our lanterns gained approval from Japanese authorities and were successfully installed on Japan’s first offshore wind farm—a testament to our commitment to innovation.

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.

MRASS for U.S. Requirements

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.

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.
