Where applicable, ISO 13628-6:2006 can be used for equipment on multiple-well applications. ISO 13628-6:2006 establishes design standards for systems, subsystems, components and operating fluids in order to provide for the safe and functional control of subsea production equipment. ISO 13628-6:2006 contains various types of information related to subsea production control systems. They are informative data that provide an overview of the architecture and general functionality of control systems for the purpose of introduction and information; basic prescriptive data that shall be adhered to by all types of control system; selective prescriptive data that are control-system-type sensitive and shall be adhered to only when they are relevant; optional data or requirements that need be adopted only when considered necessary either by the purchaser or the vendor. In view of the diverse nature of the data provided, control system purchasers and specifiers are advised to select from ISO 13628-6:2006 only the provisions needed for the application at hand. Failure to adopt a selective approach to the provisions contained herein can lead to overspecification and higher purchase costs. Rework and repair of used equipment are beyond the scope of ISO 13628-6:2006.

ISO 13628-1:2005 provides general requirements and overall recommendations for development of complete subsea production systems, from the design phase to decommissioning and abandonment. ISO 13628-1:2005 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. ISO 13628-1:2005 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.

ISO 13628-7:2005 gives requirements and recommendations for the design, analysis, materials, fabrication, testing and operation of subsea completion/workover (C/WO) riser systems run from a floating vessel. It is applicable to all new C/WO riser systems and may be applied to modifications, operation of existing systems and reuse at different locations and with different floating vessels. ISO 13628-7:2005 is intended to serve as a common reference for designers, manufacturers and operators/users, thereby reducing the need for company specifications. ISO 13628-7:2005 is limited to risers, manufactured from low alloy carbon steels. Risers fabricated from special materials such as titanium, composite materials and flexible pipes are beyond the scope of ISO 13628-7:2005.

Minimum requirements are specified for the design, material selection, manufacture, testing, marking and packaging of bonded flexible pipes, with reference to existing codes and standards where applicable. ISO 13628-10:2005 applies to bonded flexible pipe assemblies, consisting of segments of flexible pipe body with end fittings attached to both ends. ISO 13628-10:2005 applies to pipes with a design pressure greater than or equal to 1,5 MPa (15 bar). ISO 13628-10:2005 can be used for lower design pressure pipes, though the requirements of these pipes have not been specifically addressed. ISO 13628-10:2005 does not cover flexible pipes of unbonded structure nor to flexible pipe ancillary components and does not apply to flexible pipes for use in choke and kill line applications.. ISO 13628-10:2005 can be applied to flexible pipes that include non-metallic reinforcing layers, though no effort was made to address the specific and unique technological aspects of this product, and to a bonded construction pipe that includes a material or layer construction that is covered in ISO 13628-2. ISO 13628-10:2005 can be applied to flexible pipes for pile hammer, gas flare, water supply and jetting applications, though no effort was made to address the specific and unique technological aspects relating to each of these requirements.

ISO 13628:2002 gives functional requirements and guidelines for ROV interfaces on subsea production systems for the petroleum and natural gas industries. It is applicable to both the selection and use of ROV interfaces on subsea production equipment, and provides guidance on design as well as the operational requirements for maximising the potential of standard equipment and design principles. The auditable information for subsea systems it offers will allow interfacing and actuation by ROV-operated systems, while the issues it identifies are those that have to be considered when designing interfaces on subsea production systems. The framework and detailed specifications set out will enable the user to select the correct interface for a specific application.
