The vessel
was alongside for maintenance and repair. Work continued as
scheduled until welding fumes in the engine workshop caused
the fire alarms to sound. To prevent further alarms this zone
was isolated. On completion of the days work hourly fire patrols
were started as usual, however reactivation of the fire detection
for the isolated zone was missed out.
Later in the night the fire alarms sounded again, this time
however neither the ships crew nor the shore fire brigade could
reach the engine workshop area
