Marine Lantern

The next generation marking for offshore wind turbines. It comes in two intensities; 2NM and 5NM yellow. The new design is made for easy handling, installation and maintenance.

Rugged – Stainless steel housing and watertight electronics protect against the harsh offshore environment.

NAi interface – Communication and power are provided through the NAi network.

LED technology – Using the highest quality LED technology, the LED 160 provides the highest light output with low power consumption.

Low maintenance – With simple interfaces, LED technology and remote monitoring, the Seamark Marine Lantern is extremely low maintenance.

Standards – The SeaMark Marine Lantern satisfies the IALA recommendation 0-139 guidelines for offshore structures.

 

Configuration Options

  • Available Intensities – 2 & 5 Nautical mile
