Northern Offshore’s jackup rig Energy Enhancer will be marked by Tideland Signal’s Syncrolan LED light stations when it goes on station in the North Sea. To warn shipping in the vicinity of the rig, Northern Offshore have installed three Tideland Syncrolan LED light stations with a central battery bank and a 24v charger, which provide 96 hours back-up for the secondary lights.
Tideland’s Syncrolan light stations combine an MLED-180HI EX LED main light with a range of 15 NM and an MLED-150 EX LED secondary light with a range of 10 NM. The whole assembly is mounted on a galvanised steel pedestal and wired to an Exd monitoring/switching enclosure that provides a fail alarm to an existing central monitoring panel.
Tideland’s MLED-150 and MLED-180 lanterns offer minimal maintenance requirements and an expected service life in excess of twenty five years on station in the most demanding environments. Long-life LEDs and high-integrity electronics are employed to maximise reliability and minimise maintenance.
The light stations are ATEX certified for use in Zone 1 (Cat 2) hazardous areas.
