Range : 2 NM
Ideal for : offshore platforms & drilling rigs
Marine lantern is one of marine navigation type icluding for port used. The LIEX-SS is a compact and reliable explosion proof fog signal emitter designed for deployment as a 2NM sound signal as designated by IALA for audible warning for offshore structures.
Designed for long service life in harsh environments with low maintenance, it’s rugged construction makes it ideal for :
• Offshore oil platforms.
• Offshore drilling rigs.
• Offshore wind farms.
• CALM buoys.
• Floating production systems (FPSOs).
Features :
-
Output is omnidirectional or directional with sound absorbing baffle (optional).
-
Synchronising may also be accomplished by a centralised master coder with self-test feature or remote GPS.
-
Terminals are also provided for a 2-hour temporary silence control.
-
Power supply includes remote code selector terminals for changing the sounding rhythm and terminals for synchronisation with other horns or lights.
-
Sounding Morse code ‘U’, operating from optional local and/or remote control panels.
-
Microprocessor-based control electronics; oscillator, coding timer and control electronics are located in a separate Ex ‘d’ housing.
-
Designed at an optimum frequency to maximise range of 2NM fog signal emitter to IALA and USCG guidelines.
