EN ISO 15138:2007 (E)3DIN EN ISO 15138:2008-07 1 Scope This International Standard specifies requireme
23、nts and provides guidance for 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 person
24、nel or not normally occupied by personnel, fixed or floating but registered as an offshore production installation. For installations that can be subject to “Class” or “IMO/MODU Codes b) acceptable air quality in all adverse weather conditions; c) reliable performance through concept selection, the
25、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) maintai
26、nability 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 the survivability in the TR by preventing ingress of potentially flammable gas-air mixtures through approp
27、riate siting, isolation, pressurization, provision of multiple air-intake locations, sufficient number of air changes, gas detection and emergency power supply; EN ISO 15138:2007 (E)7DIN EN ISO 15138:2008-07 prevent the formation of potentially hazardous concentrations of flammable gaseous mixtures
28、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
29、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
30、midity- and temperature-controlled environment 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 sub
31、clauses of this International Standard. Functional requirements in the development of a basis of design 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 id
32、entification 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 calcula
33、tions (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 International Standard, the use of the term “ventilation” should be taken to in
34、clude 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 de
35、velopment of a design basis shall be progressed using the practices that are identified in this International Standard, though it should be recognized that it involves a process of iteration as the design matures and does not take place as the sequential series of steps used in this International St
36、andard to facilitate presentation. 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
37、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 haz
38、ard and operability study (HAZOP) technique may be used for this. EN ISO 15138:2007 (E)8DIN EN ISO 15138:2008-07 In 5.2, objectives are identified which establish the goals. Detailed requirements that enable the objectives to be achieved are outlined. It is the responsibility of the user to assess w
39、hether the requirements in this International Standard are acceptable to the local regulator. In 5.3, the fundamental choice in system design, i.e. between natural and mechanical methods of ventilation, is addressed. The functional requirements associated with the design of HVAC systems for differen
40、t areas of a typical offshore installation that require particular technical considerations due to their location and/or their function are given in 5.4. Figure 1 is intended to illustrate the processes undertaken at various stages of the installation life cycle and to identify reference documents a
41、nd the appropriate subclauses of this International Standard that provide the necessary requirements. Figure 1 Application of this International Standard to a project life cycle EN ISO 15138:2007 (E)9DIN EN ISO 15138:2008-07 5.2 Development of design basis 5.2.1 Orientation and layout 5.2.1.1 Object
42、ive The objective is to provide input into the early stages of design development so that areas and equipment that can have a requirement for HVAC, or be affected by its provision, are sited in an optimum location, so far as is reasonably practicable. 5.2.1.2 Functional requirements Installation lay
43、out requires a great deal of coordination between the engineers involved during design and the operation, maintenance and safety specialists. Attention shall also be paid to the minimization of construction, offshore hook-up and commissioning. It is not the intention of this International Standard t
44、o detail a platform-layout philosophy, but to identify areas where considerations of the role of HVAC, and requirements for it, can have an impact in the decision making surrounding installation orientation and layout. Installations can have a temporary refuge (TR). The TR is in almost all cases the
45、 living quarters (LQ), where they are provided. The survivability of the TR, which is directly related to the air leakage rate, can introduce consideration of active HVAC systems for pressurization of the TR or enclosed escape and evacuation routes. Active systems require detailed risk-assessment ex
46、ercises to be undertaken as part of the design verification, and passive systems are generally preferred since they do not rely on equipment functioning under conditions of emergency. Hazardous areas, particularly those containing pressurized hydrocarbon systems, should be located as far as practica
47、ble from the TR, so that any gas leaks are naturally dispersed. The layout shall include correct positioning of ventilation inlets and outlets, engine inlets and exhausts, vents and flares to allow for safe operation, particularly of the TR. Hot exhausts shall not interfere with crane, helicopter, p
48、roduction or drilling operations or the LQ, and shall be directed so as not to be drawn into gas-turbine air intakes. Air intakes to hazardous and non-hazardous areas shall be located as far as is reasonably practicable from the perimeter of a hazardous envelope and not less than the minimum distanc
49、e specified in the prevailing area classification code. The location of the air inlet shall also be evaluated for availability in emergency situations. 5.2.1.3 Detailed requirements Results of wind-tunnel model tests or CFD calculations on the installations shall be used as a basis for determining the external zone(s) of wind pressure in which to locate the intake(s) and outlet(s) for the HVAC system(s). Particular care shall be taken in locating air intakes and
