Refurbishing sulphur stockyard runway

PCT handles sulphur, which is unloaded from railcars by rotary dumper and stored in open stockpiles, and ethylene glycol, which is unloaded on four Rack Tracks and stored in their Tank Farm.

A rail-mounted StakRake (stacker/reclaimer) is used to stockpile and reclaim sulphur from a centre-mounted conveyor to stockpiles on each side of the runway.

The runway is 440 m long and consists of two parallel concrete pedestals with a 135 lb crane rail mounted on each pedestal at a gauge of 762 m (25 ft). The existing StakRake runway was in dire need of replacement. The existing rails and fastenings were corroded, the horizontal and vertical alignment was approaching maximum operating limits, and the concrete pedestals were deteriorating due to sulphate attack.

Ausenco provided assistance with EPCM activities for the refurbishment of the existing runway which occurred during two planned shutdowns in 2009 and 2010.
