This part of 13628 provides general requirements and overall recommendations for development of complete subsea production systems from the design phase to decommissioning. This part of 13628 forms a top-level document to govern other standards dealing with subsystems typically forming a part of a subsea production system. The complete subsea production system comprises several subsystems necessary to produce hydrocarbons from one or more subsea wells to a given processing facility located offshore (fixed, floating or subsea) or onshore, or to inject water/gas through subsea wells. This part of 13628 and the subsystem standards apply as far as the interface
