Standard for Subsea Production Control Systems

1. Scope

   
   

   This standard is applicable to the design, fabrication, testing, installation, and operation of subsea production control systems (SPCS).

   
   

   This standard covers surface control system equipment, subsea-installed control system equipment, and control fluids. This equipment is used for control of subsea production of oil and gas and for subsea water and gas injection services. Where applicable, this standard can be used for subsea processing equipment.
