1 Scope This part of ISO 13628 provides general requirements and overall recommendations for development of complete subsea production systems, from the design phase to decommissioning and abandonment. This part of ISO 13628 is intended as an umbrella document to govern other parts of ISO 13628 dealing with more detailed requirements for the subsystems which typically form part of a subsea production system. However, in some areas (e.g. system design, structures, manifolds, lifting devices, and colour and marking) more detailed requirements are included herein, as these subjects are not covered in a subsystem standard. The complete subsea production system comprises several subsystems necessary to produce hydrocarbons from one or more subsea wells and transfer them to a given processing facility located offshore (fixed, floating or subsea) or onshore, or to inject water/gas through subsea wells. This part of ISO 13628 and its related subsystem standards apply as far as the interface limits described in Clause 4. Specialized equipment, such as split trees and trees and manifolds in atmospheric chambers, are not specifically discussed because of their limited use. However, the information presented is applicable to those types of equipment. If requirements as stated in this part of ISO 13628 are in conflict with, or are inconsistent with, requirements as stated in the relevant complementary parts of ISO 13628, then the specific requirements in the complementary parts take precedence. 2 Normative references The following referenced documents are indispensable for the application of this document.

3 Terms, definitions and abbreviations For the purposes of this document, the following terms, definitions and abbreviated terms apply. 3.1 Terms and definitions 3.1.1 barrier element forming part of a pressure-containing envelope which is designed to prevent unintentional flow of produced/injected fluids, particularly to the external environment 3.1.2 deep water water depth generally ranging from 610 m (2 000 ft) to 1 830 m (6 000 ft) NOTE Since the physical circumstances of any situtation will change as a function of water depth, use of the term “deep water” implies that it may be necessary to consider design and/or technology alternatives. 3.1.3 first-end connection connection made at the initiation point of the flowline or umbilical installation process 3.1.4 flowline production/injection line, service line or pipeline through which fluid flows NOTE In this part of ISO 13628, the term is used to describe solutions or circumstances of general nature related to a flowline. 3.1.5 flying lead unarmoured umbilical jumper with a termination plate at either end (incorporating connectors for the various lines) used to connect subsea facilities together NOTE 1 A flying lead is commonly used to connect e.g. a subsea control module on a subsea tree to a subsea umbilical distribution unit. NOTE 2 This type of umbilical jumper is lightweight and hence can be picked up from a deployment basket on the seabed and manoeuvred into position using a free-flying ROV.
3.1.6 jumper short segment of flexible pipe with a connector half at either end NOTE A jumper is commonly used to connect flowlines and/or subsea facilities together, e.g. a subsea flowline to a hard pipe riser installed on a production platform. 3.1.7 process valve any valve located downstream of the tree wing valves in the production flow path 3.1.8 pull-in head device used for terminating the end of a flowline or umbilical so that it can be loaded/offloaded from a vessel and pulled along the seabed and/or through an I-tube or J-tube 3.1.9 second-end connection connection made at the termination point of the flowline or umbilical installation process 3.1.10 spool short segment of rigid pipe with a connector half at either end NOTE A spool is commonly used to connect flowlines and/or subsea facilities together, e.g. a subsea tree to a subsea manifold. 3.1.11 ultra-deep water water depth exceeding 1 830 m (6 000 ft) NOTE 1 Since the physical circumstances of any situtation will change as a function of water depth, use of the term “ultra-deep water” implies that it may be necessary to consider design and/or technology alternatives. NOTE 2 For description of pressure and temperature ratings, the definition given in the applicable subsystem International Standard and other relevant standards and design codes is used. 3.1.12 umbilical jumper short segment of umbilical with a termination plate at either end (incorporating connectors for the various lines) used to connect subsea facilities together NOTE An umbilical jumper is commonly used to connect e.g. a subsea umbilical termination to a subsea umbilical distribution unit.
