The work of preparing International Standards is normally carried out through ISO technical
23、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
24、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
25、 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.
26、 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 the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this do
27、cument is information given for the convenience of users and does not constitute an endorsement.For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the World Trade

29、ing equipment and systems.This third edition cancels and replaces the second edition (ISO 15138:2007), which has been technically revised.The main changes compared to the previous edition are as follows: minimum and maximum temperatures have been added to 5.2.3.3.4 below Table 2 for clarification; a
30、 requirement for black start has been added to 5.3; requirements for the specific areas stairways/escape routes and air locks have been added to 5.4; phase-down and phase-out of high and medium global warming potential (GWP) refrigerants are addressed in 5.4; a reference to new filtration standard a
31、nd note for chemical filtration have been added to Table A.1; fail safe criteria for fire damper for safety critical areas have been added to Clause A.9; requirements for duct earthing have been added to B.1.1; the datasheet for DX cooling coil has been updated with electronic expansion valve; the d
32、atasheet for heating coils has been updated with data for self-generated noise.iv ISO 2018 All rights reservedBS EN ISO 15138:2018Petroleum and natural gas industries - Offshore production installations - Heating, ventilation and air-conditioning1 ScopeThis document specifies requirements and provid
33、es guidance for the design, testing, installation and commissioning of heating, ventilation, air-conditioning and pressurization systems, and equipment on all offshore production installations for the petroleum and natural gas industries that are new or existing, normally occupied by personnel or no
34、t normally occupied by personnel, and fixed or floating but registered as an offshore production installation.This document is normally applicable to the overall facilities. For installations that can be subject to “Class” or “IMO/MODU Codes b) acceptable air quality in all adverse weather condition
35、s;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 diagno
36、stics;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 potent
37、ially 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
38、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 are
39、as; 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 hu
40、midity- 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 appr
41、opriate 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); hazard identifi
42、cation 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);4 ISO 2018 All rights reservedBS
43、EN ISO 15138:2018ISO 15138:2018 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 t
44、he 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
45、 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 pr
46、esented 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 knowled
47、ge 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
48、 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
49、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.
