Incident Location

Fixed Installation

Incident Activity

Production operations

Specific Incident Equipment

Pumping Equipment

Lessons Identified

• Equipment flushed, drained and positively isolated as per procedures still presents a loss of containment risk if the equipment drainage and flushing points are not adequate in terms of number and location.

Incident Recommendations

• Source a more suitable bund as an interim measure until feedback obtained regarding possible drainage modifications.
• Update procedure for flushing, draining and isolating pump for outage, taking into account whether pump is being removed for maintenance after a ‘failure’ or for a cartridge ‘upgrade’.
• Add lessons learned to WCC for task to ensure that this issue is highlighted the next time the task is repeated.
