Guidance for installation procedures and tolerances of hydroelectric machines - Part 4: Vertical Kaplan or propeller turbines (IEC 63132-4:2020)
The purpose of this this part of IEC 63132 is to establish, in a general way, suitable
procedures and tolerances for the installation of a vertical Kaplan or propeller turbine. This
document presents a typical assembly and whenever the word “turbine” is used in this
document, it refers to a vertical Kaplan or propeller turbine. There are many possible ways to
assemble a unit. The size of the machine, design of the machine, layout of the powerhouse or
delivery schedule of the components are some of the elements that could result in additional
steps, the elimination of some steps and/or assembly sequences.
It is understood that a publication of this type will be binding only if, and to the extent that,
both contracting parties have agreed upon it.
This document excludes matters of purely commercial interest, except those inextricably
bound up with the conduct of installation.
The tolerances in this document have been established upon best practices and experience,
although it is recognized that other standards specify different tolerances.
Wherever this document specifies that documents, drawings or information is supplied by a
manufacturer (or by manufacturers), each individual manufacturer will furnish the appropriate
information for their own supply only.

IEC 63132-4:2020 L’objectif de la présente partie de l'IEC 63132 est d’établir, d’une façon générale, des procédures et des tolérances adéquates pour l’installation des turbines et alternateurs hydroélectriques. Ce document présente un assemblage typique et à chaque fois que le mot "turbine" est utilisé, il signifie une turbine Kaplan ou à hélice verticale. Il y a plusieurs façons possibles pour assembler un groupe. Les dimensions des machines, la conception des machines, le plan de la centrale et l’échéancier des livraisons des différentes composantes sont quelques éléments qui peuvent résulter en l’ajout d’étapes, l’élimination de certaines étapes et/ou des séquences d’assemblages.
Il est entendu que ce type de document sera contraignant seulement si, et dans la mesure où, les deux parties contractuelles l’ont convenu.
Ce document exclut les questions d’intérêt purement commercial, sauf celles inextricablement liées au déroulement de l’installation.
Les tolérances mentionnées dans ce document ont été déterminées selon les meilleures pratiques et l’expérience, bien qu’il soit reconnu que d’autres normes spécifient des tolérances différentes.
Partout où ce document précise que des documents, des dessins ou des renseignements sont fournis par un fabricant (ou par des fabricants), chaque fabricant fournit les informations appropriées pour leur propre approvisionnement seulement.

Part 4: Vertical Kaplan or propeller turbines
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

5 Steps
5.1 Turbine embedded parts
5.1.1 Step 1: Benchmarks set-up
a) Objective of work in the step
– Set-up benchmarks to be used for starting proper installation of the turbine.
b) Explanation of work
– Sufficient benchmarks should be provided to establish the unit centreline, axis and
elevation.
c) Recommendations
N/A
d) Additional information
Depending on the project delivery system (EPC, design build, etc.), the benchmarks or
their reference points could be provided by the owner, civil contractor, etc. Whoever
provides the benchmarks or reference points is responsible to make sure they are correct.
The benchmark type (x, y, z coordinates, defining axis and elevations, etc.) should be
agreed to prior to the work commencing.
The turbine supplier should take care to transfer the necessary benchmarks throughout
the erection and/or concreting processes so that the benchmarks remain accessible as the
unit is assembled.
5.1.2 Step 2: Primary embedded pipes and draft tube liner foundation installation
a) Objective of work in the step
– Install primary embedded pipes and steel foundations in the correct locations.
b) Explanation of work
– Install the primary embedded pipes and supporting systems.
– Install the foundation components of the draft tube liner.
c) Recommendations
Different designs require different tolerances; therefore, it is recommended that the turbine
supplier should provide the tolerances. It is considered as a best practice to perform:
– NDT as applicable (i.e. Visual inspections, pressure tests of the piping, test of welding
seams);
– measures to prevent the concrete from entering the pipes or contaminating the
machined surfaces of foundations during concreting.
d) Additional information
The contract should define which party is responsible to install the primary embedded
pipes and/or the draft tube liner foundation components.
5.1.3 Step 3: Draft tube liner foundation embedment
a) Objective of work in the step
– Embed the foundation components of the draft tube liner and the primary embedded
piping in the concrete.
b) Explanation of work
– Embed the foundation components of the draft tube liner.

c) Recommendations
Care should be taken not to damage any of the embedded components or piping when
placing concrete
d) Additional information
N/A
5.1.4 Step 4: Draft tube liner foundation and workspace verification
a) Objective of work in the step
– Confirm that the draft tube liner foundations have been installed in the correct place,
verifying that the draft tube pit for placing the draft tube liner is per the design and
there is sufficient access to the workplace.
b) Explanation of work
– Ensure that the dimensions of the draft tube pit match the design.
– Ensure that there will be no interference between the concrete structures, the
reinforcing steels, the scaffolding, etc., and the foundation anchors, the embedded
pipes and the draft tube liner.
– Once the workplace is acceptable the turbine installation work can start.
c) Recommendations
It is recommended to check that the foundation components of the draft tube liner and the
primary embedded pipes were installed within the tolerances provided by the turbine
supplier.
d) Additional information
