Overview

The standard prEN ISO 13628-17:2010 titled "Petroleum and natural gas industries - Design and operation of subsea production systems - Part 17: Guidelines for flexible pipe ancillary equipment" provides comprehensive guidelines for the lifecycle management of ancillary equipment associated with flexible pipes used in subsea production systems. Developed in collaboration between ISO and CEN, this draft standard targets professionals in the petroleum and natural gas industries involved in subsea infrastructure design, manufacture, handling, and integrity management.

This recommended practice supplements existing requirements specified in N384 and is intended to be used alongside other standards such as EN ISO 13628-2 and prEN ISO 13628-11. Its holistic approach ensures the reliable and safe design, material selection, testing, installation, and maintenance of flexible pipe ancillary equipment critical to subsea production reliability.

Key Topics

• Design Considerations
  The standard outlines essential design criteria for ancillary equipment components such as bend stiffeners, bend restrictors, bellmouths, buoyancy and ballast modules, subsea buoys, and tethers. Focus is on ensuring compatibility with flexible pipes and the operational environment.

• Materials Selection
  Guidance on selecting appropriate materials to withstand subsea conditions including corrosion, pressure, and mechanical stresses is provided. Materials must meet durability and performance requirements for long-term subsea deployment.

• Analysis and Testing
  The document details analysis methodologies and prototype testing procedures to validate structural integrity, performance under operational loads, and compliance with design specifications before deployment.

• Manufacturing and Handling
  Recommendations cover manufacturing best practices to maintain quality, as well as handling, transportation, and installation procedures to prevent damage and assure the integrity of ancillary equipment.

• Integrity Management
  Emphasis is placed on ongoing inspection, monitoring, and maintenance strategies to manage asset life, detect degradation, and prevent failures in subsea flexible pipe systems.

Applications

• Subsea Production Systems
  The guidelines apply directly to the development and operation of subsea oil and gas production infrastructure where flexible pipes connect surface facilities to subsea wells and equipment.

• Flexible Pipe Systems
  Ancillary equipment such as bend stiffeners and bend restrictors are critical for controlling the bending radius and mechanical integrity of flexible pipes deployed in hostile subsea environments.

• Pipeline Installation and Maintenance
  Ensuring the proper design and handling of ancillary equipment facilitates safe installation, reliable function, and ease of maintenance of subsea flexible pipe systems, thereby reducing downtime and operational risks.

• Offshore Engineering Projects
  Engineers and project managers involved in offshore infrastructure benefit from applying this standard to optimize design and operational procedures in subsea pipeline projects.

Related Standards

• N384
  Specifies minimum requirements for the design, material selection, manufacture, documentation, testing, marking, and packaging of flexible pipe ancillary equipment.

• EN ISO 13628-2
  Covers design and operation of subsea production systems focusing on flexible pipe design principles.

• prEN ISO 13628-11
  Provides guidelines on jumper assemblies for subsea systems, complementing flexible pipe ancillary equipment standards.

Together, these standards form a system approach ensuring safety, reliability, and performance of subsea production systems utilizing flexible pipes and related components.

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 2.
The main task of technical committees is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13628-17 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore
structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 4, Drilling and
production equipment.

Introduction
This part of ISO 13628 is the result of a Joint Industry Project to develop a worldwide industry standard for the
design, material selection, analysis, testing, manufacture, handling, transportation, installation and integrity
management of flexible pipe ancillary equipment. The objective of this part of ISO 13628 is to provide an
integrated approach, together with ISO 13628-16, ISO 13628-2 and ISO 13628-11, to the design of flexible
pipe systems. Therefore it is intended that this part of ISO 13628 be used in close conjunction with these
documents.
The majority of ancillary equipment is custom-built and can be designed and manufactured in a variety of
methods. It is not the intent of this part of ISO 13628 to discourage novel or new developments in ancillary
equipment. On the contrary, it is recognised that a variety of designs and methods are possible. For this
reason, some topics are presented in general terms to provide guidance to the user while still leaving open the
possibility of using alternative approaches. The reader should be aware that ancillary equipment technology
(concepts, design and analysis methodologies and criteria, components manufacturing and testing,
operational roles and demands, maintenance and inspection, etc.) is in a state of rapid and continuing
evolution. Potential users therefore need to apply care in their application of the recommendations within this
part of ISO 13628.
Systeme Internationale (SI) units are used in this part of ISO 13628. United States Customary (USC) units
may be given in brackets after the SI units.

Part 17:
Guidelines for flexible pipe ancillary equipment
1 Scope
This part of ISO 13628 provides guidelines for the design, materials selection, analysis, testing, manufacture,
handling, transportation, installation and integrity management of flexible pipe ancillary equipment. It
supplements ISO 13628-16, which specifies minimum requirements for the design, material selection,
manufacture, documentation, testing, marking and packaging of flexible pipe ancillary equipment.
This part of ISO 13628 presents the current best practice for design and procurement of ancillary equipment,
and gives guidance on the implementation of the specification for standard flexible pipe products. In addition,
this part of ISO 13628 presents guidelines on the qualification of prototype products.
The applicability relating to a specific item of ancillary equipment within this part of ISO 13628 is stated at the
beginning of the clause dedicated to that item of ancillary equipment.
This part of ISO 13628 applies to the following flexible pipe ancillary equipment:
a) bend stiffeners;
b) bend restrictors;
c) bellmouths;
d) buoyancy modules and ballast modules;
e) subsea buoys;
f) tethers for subsea buoys and tether clamps;
g) riser and tether bases;
h) clamping devices;
i) piggy-back clamps;
j) repair clamps;
k) I/J-tube seals;
l) pull-in heads/installation aids;
m) connectors;
n) load-transfer devices;
o) mechanical protection;
DRAFT 2010
ISO/DIS 13628-17
p) fire protection.
This part of ISO 13628 may be used for bonded flexible pipe ancillary equipment, though any requirements
specific to these applications are not addressed.
Where relevant, the applicability of recommendations to umbilicals is indicated in the Applicability subclause
for the ancillary equipment in question.
This part of ISO 13628 does not cover flexible pipe ancillary equipment beyond the connector, with the
exception of riser bases and load-transfer devices. Therefore this part of ISO 13628 does not cover turret
structures or I-tubes and J-tubes, for example. In addition, this part of ISO 13628 does not cover flexible pipe
storage devices, for example reels.
This part of ISO 13628 is intended to cover ancillary equipment made from several material types, including
metallic, polymer and composite materials. This part of ISO 13628 may also refer to material types for
particular ancillary components that are not commonly used for such components currently, but may be
adopted in the future.
This part of ISO 13628 applies to ancillary equipment used in association with the flexible pipe applications
listed in Clause 1 of ISO 13628-2:2006 and in ISO 13628-11.
