Industries du pétrole et du gaz naturel - Conception et exploitation des systemes de production immergés - Partie 6: Commandes pour équipements immergés (ISO 13628-6:2006)

L'ISO 13628-6:2006 s'applique à la conception, à la fabrication, aux essais, à l'installation et au fonctionnement des commandes pour équipements immergés.
Elle traite des équipements de surface, des équipements immergés et des fluides de commande. Ces équipements servent à la commande de la production sous-marine de pétrole et de gaz et aux services immergés d'injection d'eau et de gaz. L'ISO 13628-6:2006 peut, le cas échéant, être utilisée pour des équipements destinés à des applications multipuits.
L'ISO 13628-6:2006 élabore les normes de conception des systèmes, sous-systèmes, composants et fluides d'exploitation afin d'assurer la commande fonctionnelle en toute sécurité des équipements de production immergés.
Elle contient différents types d'informations en rapport avec les commandes pour équipements immergés. Il s'agit de données informatives proposant un aperçu de l'architecture et des fonctionnalités générales des commandes à des fins de présentation et d'information, de données prescriptives élémentaires auxquelles tous les types de commande doivent se conformer, de données prescriptives sélectives dépendant du type de commande devant être appliquées uniquement lorsqu'elles sont pertinentes et de données ou exigences facultatives devant être adoptées uniquement lorsque l'acheteur ou le fournisseur le jugent nécessaire.
Étant donné la diversité des données fournies, il est conseillé aux acheteurs et spécificateurs de commandes de ne sélectionner que les dispositions de l'ISO 13628-6:2006 requises pour leur application. Le défaut de suivre une approche sélective des dispositions contenues ici risque de donner lieu à une spécification excessive et à des coûts d'achat bien supérieurs.
Le réusinage et la réparation des équipements utilisés ne rentrent pas dans le cadre de l'ISO 13628-6:2006.

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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
boost
pressure maintained on the spring-return side of a subsea actuator for the purposes of improving closing-time
response
© ISO 2006 – All rights reserved 3

---------------------- Page: 11 ----------------------

ISO 13628-6:2006(E)
3.2
commanded closure
closure of the underwater safety valve and possibly other valves depending on the control system design
NOTE Such commands can originate manually, automatically or as part of an ESD.
3.3
control path
total distance that a control signal (e.g. electrical, optical, hydraulic) travels from the topside control system to
the subsea control module or valve actuator
3.4
design pressure
maximum pressure for which the system or component was designed for continuous usage
3.5
design life
specified operational life of system after pre-delivery test
3.6
diagnostic data
data provided to monitor the condition of the downhole equipment
NOTE Can include the ability to make (engineering) adjustments.
3.7
direct hydraulic control
control method wherein hydraulic pressure is applied through an umbilical line to act directly on a subsea
valve actuator
NOTE Upon venting of the pressure at the surface, the control fluid is returned through the umbilical to the surface
due to the action of the restoring spring in the valve actuator. Subsea functions may be ganged together to reduce the
number of umbilical lines.
3.8
downstream
away from a component in the direction of flow
3.9
electrohydraulic control
control method wherein communication signals are conducted to the subsea system and used to open or
close electrically-controlled hydraulic control valves
NOTE Hydraulic fluid is locally sourced and acts on the associated subsea valve actuator. “Locally sourced” may
mean locally stored pressurized fluid or fluid supplied by a hydraulic umbilical line. With electrohydraulic control systems,
data telemetry (readback) is readily available at high speed. Multiplexing of the communication signals reduces the
number of conductors in the umbilical.
3.10
expert operation
operating the IWCS with other control commands or other methods than used for normal operation
NOTE Typically used by IWCS supplier or other skilled resource to read IWCS diagnostic data and make
(engineering) adjustments to IWCS equipment.
3.11
hydrostatic test pressure
maximum test pressure at a level greater than the design pressure (rated working pressure)

NOTE An example is the subsea control-module running tool.
3.19
shift time
period of time elapsed between the arrival of a control signal at the subsea location (the completion of the
signal time) and the completion of the control function operation
NOTE Of primary interest is the time to fully stroke, on a subsea tree, a master or wing valve that has been
designated as the underwater safety valve.
3.20
signal time
period of time elapsed between the remote initiation of a control command and the initiation of a control
function operation subsea (the commencement of the shift time)
3.21
