ISO 15551-1:2015

Petroleum and natural gas industries — Drilling and production equipment — Part 1: Electric submersible pump systems for artificial lift

ISO 15551-1:2015 provides requirements for the design, design verification and validation, manufacturing and data control, performance ratings, functional evaluations, handling, and storage of tubing-deployed electrical submersible pump (ESP) systems as defined herein. This part of ISO 15551 is applicable to those components meeting the definition of centrifugal pumps including gas handling devices, discharge heads, seal chamber sections, intake systems, mechanical gas separators, induction motors (herein motor), shaft couplings, motor lead extension, pothead, and power cables, as defined herein. Components supplied under the requirements of this part of ISO 15551 exclude previously used subcomponents. Additionally, this International Standard provides requirements for assembled ESP systems. ISO 15551-1:2015 includes normative annexes addressing design validation performance rating requirements by component, requirements for determining ratings as an assembled system, functional evaluation: single component and cable reference information. ISO 15551-1:2015 includes informative annexes addressing functional evaluation guidelines for assembled ESP systems, establishing recommended operating range (ROR) of the ESP system, example user/purchaser ESP functional specification form, considerations for the use of 3-phase low and medium voltage adjustable speed drives for ESP applications, analysis after ESP use, downhole monitoring of ESP assembly operation, and information on permanent magnet motors for ESP applications. Equipment not covered by this part of ISO 15551 includes wireline and coiled tubing-deployed ESP systems, motor and pump shrouds, electric penetrators and feed-through systems, cable clamps and banding, centralizers, intake screens, passive gas separators, by-pass tools, check and bleeder valves, component adaptors, capillary lines, electric surface equipment, downhole permanent magnet motors, and non-conventionally configured ESP systems such as inverted systems. Repair and redress equipment requirements are not covered in this part of ISO 15551. The terminologies used within this part of ISO 15551 are; "ESP assembly" for a system of products combined into an operational machine, "component" for individual products such as, pumps or seal chamber sections, and "subcomponent" for individual parts or subassemblies that are used in the construction of an individual component.

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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

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. Details of any

patent rights identified during the development of the document will be in the Introduction and/or on

Introduction

This part of ISO 15551 has been developed by users/purchasers and suppliers/manufacturers of electric

submersible pumps and is intended for use in the petroleum and natural gas industry worldwide. This

part of ISO 15551 provides requirements and information to both parties in the selection, manufacturing,

testing, and use of electric submersible pumps as defined in the scope. Further, this part of ISO 15551

addresses supplier requirements, which set the minimum parameters for claiming conformity with this

International Standard.

This part of ISO 15551 provides grades of requirements for design validation, quality control, and

functional evaluations allowing the user/purchaser to select each for a specific application. There are

two grades of design validation, three grades of quality control, and up to three grades of functional

testing, depending on the component. Design validation grade V2 is restricted to legacy products,

and the highest grade is V1. Quality control grade 3 is the standard grade and grades 2 and 1 provide

additional requirements. Of the three functional evaluation grades, the lowest grade is the standard

grade and higher grades provide additional requirements. The user/purchaser can specify requirements

supplemental to these grades.

Users of this International Standard are informed that requirements above those outlined in this

International Standard can be needed for individual applications. This International Standard is not

intended to inhibit a supplier/manufacturer from offering, or the user/purchaser from accepting,

alternative equipment or engineering solutions. This can be particularly applicable where there is

innovative or developing technology.
