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

5 Design
5.1 General
This clause provides requirements on all aspects of the design of heating, ventilation and air-
conditioning (HVAC) systems for offshore installations for the petroleum and natural gas industries.
For requirements and guidance on air change rates and pressurization requirements, reference is made
to classification codes for the specific project.
The HVAC systems form part of the safety services of the installation. The key functional requirements
for HVAC systems applicable to all areas of the installation are as follows:
a) sufficient ventilation, heating and cooling capacity in all adverse weather conditions;
b) acceptable air quality in all adverse weather conditions;
c) reliable performance through concept selection, the design having the following features in
decreasing order of importance:
1) simplicity, with a preference for passive systems;
2) inherent robustness by providing design margins for systems and equipment;
3) fault/status indication and self diagnostics;
4) sparing of systems and equipment;
5) maintainability through testability, inspectability and ease of access.
The following additional requirements apply to specific areas in the installation to ensure their safety
goals are met:
— maintain survivability in the TR by preventing ingress of potentially flammable gas-air mixtures
through appropriate siting, isolation, pressurization, provision of multiple air-intake locations,
sufficient number of air changes, gas detection and emergency power supply;
— prevent the formation of potentially hazardous concentrations of flammable gaseous mixtures
in hazardous areas by the provision of sufficient ventilation and air distribution for the dilution,
dispersion and removal of such mixtures, and contain such mixtures, once formed, through
maintaining relative pressures, avoiding cross-contamination and providing dedicated systems for
hazardous areas;
— prevent, through pressurization, the ingress of potentially flammable gas-air mixtures into all
designated non-hazardous areas;
— maintain ventilation to all equipment and areas/rooms that are required to be operational during
an emergency when the main source of power is unavailable;
— provide a humidity- and temperature-controlled environment as required in which personnel, plant
and systems can operate effectively, free from odours, dust and contaminants, including smoke
control.
These high-level goals are supported by the lower-level functional requirements that are stated later in
the appropriate subclauses of this document.
Functional requirements for the development of a design basis for either a new project or major
modification to an existing installation are the focus of 5.2. These requirements are related to the
following:
— platform orientation and layout (5.2.1);
4 © ISO 2018 – All rights reserved
---------------------- Page: 14 ----------------------
SIST EN ISO 15138:2018
ISO 15138:2018(E)
— hazard identification and hazardous-area classification (5.2.2);
— environmental conditions (5.2.3);
— choice of natural or mechanical ventilation systems (5.2.4);
— development of the controls philosophy (5.2.5);
— operating and maintenance philosophy (5.2.6);
— materials selection (5.2.7);
— design margins and calculations (5.2.8);
— design development and validation using wind-tunnel testing or computational fluid dynamics
(CFD) (5.2.9).
Ventilation may be natural (i.e. the wind) or mechanical or a combination of both. Throughout this
document, the use of the term “ventilation” should be taken to include either natural or mechanical
ventilation, as appropriate.
Natural ventilation is preferred over mechanical ventilation, where practical, since it is available
throughout gas emergencies, does not rely on active equipment and reduces effort required for HVAC
maintenance.
For new designs, the development of a design basis shall be progressed using the practices that
are identified in this document, though it should be recognized that the design involves a process
of iteration as it matures and does not happen as a sequential series of steps as is presented in this
document for simplicity. The processes outlined here are equally applicable to major redevelopments
of existing installations, but it can be necessary to make some compromise as a result of historical
decisions regarding layout, equipment selection and the prevailing level of knowledge at the time. The
challenge of providing cost-effective solutions in redevelopment can be significantly greater than for a
new design.
The finalized basis of design may be recorded on datasheets such as those provided in Annex D.
The completed design shall be subject to hazard-assessment review. The hazard and operability
(HAZOP) study technique may be used for this.
In 5.2, objectives are identified which establish the goals. Detailed requirements that enable the
objectives to be achieved are outlined.
In 5.3, the fundamental choice in system design, i.e. between natural and mechanical methods of
ventilation, is addressed.
In 5.4, the functional requirements associated with the design of HVAC systems for different areas of a
typical offshore installation that require particular technical considerations due to their location and/
or their function are given.
Figure 1 is intended to illustrate the processes undertaken at various stages of the installation life cycle
and to identify reference documents and the appropriate subclauses of this document that provide the
necessary requirements.
