Tideland Signal has supplied Total E&P UK with a
comprehensive package of Syncrolan light stations and fog
signals for the refurbishment of warning systems marking the
North Alwyn platforms in the North Sea.

The North Alwyn complex consists of two platforms linked
by a 73m steel bridge which takes personnel and
untreated oil and gas to the processing facility. The new
marking system comprises two main Syncrolan light stations,
two Syncrolan fog signals, three subsidiary lights and a central alarm and monitor panel. All equipment is ATEX certified for use in Zone 1 (Cat 2) hazardous areas.
Tideland’s Syncrolan light stations combine an ML-300-SL-
400-EX main light and FLMC-4 multi-code flasher with a ML-300 EX secondary light equipped with a DuoFlash EX multi code flasher. The unit is mounted on a galvanized steel pedestal incorporating a control station complete with local charger and battery.

The fog signal stations each comprise an AB-68 fog signal mounted on a galvanized steel
pedestal which also incorporates an ECU control unit battery and charger. Controls for the four
Syncrolan stations are located with the equipment but the central panel also indicates the status
of the equipment and provides photocell override to allow the lights to be switched on during
daytime and a fog signal silent switch to silence the fog signals.

The subsidiary beacons are all Tideland ML-155 units complete with a DuoFlash EX multicode
flashers and showing a red light. Of the three, two are located alongside the fog signals
and the third on the connecting bridge.
