Repairs are progressing as planned and the maintenance work scheduled for the fall has been added to the plan, extending the timing of full ramp up to mid-July. Shipments have been reduced to approximately 130 kbpd (gross) in order to complete the accelerated maintenance and are expected to ramp up as additional units complete turnaround activities.
The cause of the incident was a split in a 6-inch carbon steel line on a naphtha hydrotreater recycle circuit. Damage was largely isolated to a piperack adjacent to the hydrotreater, containing piping, cables, and electrical circuits.
The maintenance brought forward was included in Syncrude’s 2017 production plan, and there is no change to Suncor’s overall production guidance for 2017.
