Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 13628-1 was prepared by Technical Committee ISO/TC 67, Materials, equipment and
offshore structures for petroleum and natural gas industries, Subcommittee SC 4, Drilling and production
equipment.
ISO 13628 consists of the following parts, under the general title Petroleum and natural gas industries — Design
and operation of subsea production systems:
 Part 1: General requirements and recommendations
 Part 2: Flexible pipe systems for subsea and marine applications
 Part 3: Through flowline (TFL) systems
 Part 4: Subsea wellhead and tree equipment
 Part 5: Subsea control umbilicals

Introduction
This part of ISO 13628 has been prepared to provide general requirements, recommendations and overall guidance
for the user to the various areas requiring consideration during development of a subsea production system for the
petroleum and natural gas industries. The functional requirements defined in this part of ISO 13628 will allow
alternatives in order to suit specific field requirements. The intention is to facilitate and complement the decision
process rather than replace individual engineering judgement and, where requirements are non-mandatory, provide
positive guidance for the selection of an optimum solution.
This part of ISO 13628 constitutes the overall subsea production system standard, with the intention that the more
detailed requirements for the subsystems are retained in the complementary parts of ISO 13628. However, in some
areas (e.g. structures, manifolds, marking) detailed requirements are included herein, as these subjects are not
covered in a subsystem standard.
This part of ISO 13628 was developed on the basis of API RP 17A, Design and Operation of Subsea Production
Systems, and other relevant documents on subsea production systems.

Part 1:
General requirements and recommendations
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. This part of ISO 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 ISO 13628 and the 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.

4 Systems and interface descriptions
4.1 General
Complete subsea production systems range in complexity from a single satellite well with a flowline linked to a fixed
platform, to several wells on a template producing to a floating facility.
The elements of a typical subsea production system are shown in Figure 1. These are wellheads (both subsea and
mudline casing suspension systems) and trees, sealines and end connections, controls, control lines, single-well
structures, templates and manifolds, ROVs/ROTs and completion/workover and production risers (both rigid and
flexible). In some areas (not covered by subsystem standards), detailed requirements are included (these apply to
structures, manifold piping, materials, colour and marking).
The objective of this subclause is to describe the systems in general and define the subsystem interfaces. For a
detailed description of subsystems and components, see annex A.

4.2 Overall system description
4.2.1 General
Subsea production or injection systems are used to develop reservoirs, or parts of reservoirs, of a nature which
dictates drilling of the wells from more than one location. Subsea production systems may also be used to develop
reservoirs or parts of reservoirs beyond the reach of platform drilling facilities. Deep water may also in itself dictate
development of a field by means of subsea completions.
The main elements of a subsea production or injection system are:
 a wellhead system with associated casing strings and production/injection tubing;
 a structural foundation and a guidance system for orientation and lateral guidance of modules during
installation/retrieval. This unit is not always used;
 a set of flow and pressure control valves normally integrated in a tree;
 a production control system for remote monitoring and control of all subsea functions;

ISO 13628-1:1999(E)
 a protective structure (optional);
 a sealine system;
 a manifold system (optional);
 installation and intervention equipment and tools with associated control systems.
The elements of the subsea production/injection system may be configured in numerous ways, dictated by specific
field requirements and by operator strategy.
The most common configurations are:
 single satellite wells tied individually to a surface processing facility;
 one or more satellite wells tied individually to a subsea manifold located a given distance from the surface
processing facility;
 multiple wells located on a common template incorporating a manifold.
In the following, the main characteristics of these scenarios are briefly described.
4.2.2 Single satellites
For relatively shallow water, this configuration is characterized by short offset (outside the drilling reach of the host
platform if this is a combined drilling production facility) and, if an infrastructure with a surplus of tie-in capacity
exists, this scenario can be very effective. In terms of required permanent works this is basically a single satellite
development copied a number of times over. Usually the flowline and umbilical are required to be installed as first-
end tie-in at the infrastructure and second end pull-in at the satellites in order to limit congestion on the seabed
around the infrastructure.
Flowline and umbilical are for some systems connected directly to the tree structure. This approach offers some
rationalization in hardware.
4.2.3 Manifold/satellite cluster
This concept is based on tie-in of a number of single satellites to a central manifold. The manifold in turn is tied to
the infrastructure by means of one or more sealines. An arrangement including two production flowlines with same
size, service and control lines is quite common. This arrangement facilitates operation of wells at two different
pressure levels simultaneously, as well as convenient round-trip pigging.
The system has flexibility with respect to simultaneous drilling and production, which can save some drilling time,
and has flexibility with respect to installing wells in optimal locations rather than in batches at the same location, ref.
template arrangement described below.
4.2.4 Template
This concept includes some of the features described in the previous subclause, but with some notable differences.
The wells and the manifolds are located on the same structure. Headers and lines often have much of the same
configuration as the manifold/cluster option. Template designs have some additional mechanical tolerance problems
relative to cluster designs.
4.3 Subsea wellhead system
4.3.1 General
The main function of a subsea wellhead system is to serve as a structural and pressure-containing anchoring point
on the seabed for the drilling and completion systems and for the casing strings in the well. The wellhead system
incorporates internal profiles for support of the casing strings and isolation of the annuli. In addition, the system
incorporates facilities for guidance, mechanical support and connection of the systems used to drill and complete
the well.

4.3.2 Wellhead system elements
A typical wellhead system consists of the following elements:
a) a drilling guidebase with a central opening for drilling of the first section of the well and facilities for attachment
of guidelines. The temporary guidebase, acts as a support for the permanent guidebase, providing a controlled
reference point for wellhead elevation. Note that on single satellite wells the drilling guidebase may be omitted if
there are no requirements for accurately controlled elevation of the wellhead. On multiple well templates, the
drilling guidebase forms an integral part of the template;
b) a permanent guidebase with facilities for attachment to the conductor housing, and guidance of the drilling and
completion equipment (universal guide frame, BOP, production tree). If used together with a temporary
guidebase, the permanent guidebase incorporates a gimbal arrangement on the under side (curved profiles
that interfaces with a cone landing area on the temporary guidebase) to compensate for any angular
misalignment between the temporary guidebase and the permanent guidebase due to the seabed topography,
and the verticality of the well;
NOTE On satellite wells, depending on the overall tree configuration, the permanent guidebase may be replaced by
a production guidebase, prior to installation of the tree, incorporating facilities for pull-in and connection of the sealines
and connection to the tree. Alternatively, a production guidebase can be designed to serve as both the drilling guidebase
and the production guidebase. It can be either permanent or retrievable. The sealines may also be connected directly to
the tree.
c) a conductor housing welded to the conductor casing, which forms the initial anchoring point to the seabed. The
conductor housing incorporates an internal landing shoulder for the wellhead housing, and facilities on the
outside for attachment of the permanent guidebase. The conductor housing may be installed together with the
permanent guidebase;
d) a wellhead housing with internal profiles for support of all subsequent casing strings and the tubing hanger, and
external profiles for attachment of the drilling and completion equipment (BOP, tree) and landing in 762 mm
(30 in) housing;
e) casing hangers with seal and lock-down assemblies for suspension of the casing strings and isolation of the
annuli.
4.3.3 Running and retrieving tools
Dedicated tools are used to install, test and retrieve the various elements of the wellhead system. The tools are
activated by either mechanical manipulation of the drill string (push, pull, rotation) or in some cases by hydraulic
functions through the drill string or dedicated hydraulic lines. These tools interface with dedicated handling profiles
in the associated equipment.
4.3.4 Miscellaneous wellhead equi
