Functional Safety 2016

Fast developing hazards – examples

Process examples:

• Riser depacking overpressure of separator – very high pressure behind riser

valves

• Cargo pump line-up overpressure of suction – liquid filled system (almost

instant pressure rise)

Operator error:

• Opening manual valves out of sequence

• Opening a choke valve too quickly

• Opening remote operated valves out of sequence
