SeaMark
Marine Lantern
The next generation marking for offshore wind turbines. It comes in three intensities; 2NM, 3NM 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 SeaMark Marine Lantern 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 G1162 guidelines for the Marking of Offshore Man-Made Structures
