20、pects of the activities undertaken by all companies associated with the offshore recovery of hydrocarbons 1) . These management systems should be applied to all stages in the life cycle of an installation and to all related activities. Such a management system, which has been developed for environme
21、ntal issues, is described in ISO 14001 4and the principles contained in this International Standard can also be applied to issues relating to health and safety. One key element of effective management systems is a systematic approach to the identification of hazards and the assessment of the risk in
22、 order to provide information to aid decision-making on the need to introduce risk-reduction measures. Risk reduction is an important component of risk management, and the selection of risk-reduction measures will predominantly entail the use of sound engineering judgement. However, such judgements
23、may need to be supplemented by recognition of the particular circumstances, which may require variation to past practices and previously applied codes and standards. Risk-reduction measures should include those to prevent incidents (i.e. reducing the probability of occurrence), to control incidents
24、(i.e. limit the extent and duration of a hazardous event) and to mitigate the effects (i.e. reducing the consequences). Preventative measures such as using inherently safer designs and ensuring asset integrity should be emphasized wherever practicable. Measures to recover from incidents should be pr
25、ovided based on risk assessment and should be developed taking into account possible failures of the control and mitigation measures. Based on the results of the evaluation, detailed health, safety and environmental objectives and functional requirements should be set at appropriate levels. The leve
26、l and extent of hazard identification and risk assessment activities will vary depending on the scale of the installation and the stage in the installation life cycle when the identification and assessment process is undertaken. For example: complex installations, e.g. a large production platform in
27、corporating complex facilities, drilling modules and large accommodation modules, are likely to require detailed studies to address hazardous events such as fires, explosions, ship collisions, structural damage, etc.; for simpler installations, e.g. a wellhead platform with limited process facilitie
28、s, it may be possible to rely on application of recognized codes and standards as a suitable base which reflects industry experience for this type of facility; for installations which are a repeat of earlier designs, evaluations undertaken for the original design may be deemed sufficient to determin
29、e the measures needed to manage hazardous events; for installations in the early design phases, the evaluations will necessarily be less detailed than those undertaken during later design phases and will focus on design issues rather than management and procedural aspects. Any design criteria develo
30、ped during these early stages will need to be verified once the installation is operational. Hazard identification and risk assessment activities may need to be reviewed and updated if significant new issues are identified or if there is significant change to the installation. The above is general a
31、nd applies to all hazards and potentially hazardous events. 1) For example, operators should have an effective management system. Contractors should have either their own management system or conduct their activities consistently with the operators management system. BS EN ISO 10418:2003 EN ISO 1041
32、8:2003IS:81401 O3002(E) vi I SO 3002 All irhgts seredevrProcess protection system is a term used to describe the equipment provided to prevent, mitigate or control undesirable events in process equipment, and includes relief systems, instrumentation for alarm and shutdown, and emergency support syst
33、ems. Process protection systems should be provided based on an evaluation that takes into account undesirable events that may pose a safety risk. The results of the evaluation process and the decisions taken with respect to the need for process protection systems should be fully recorded. If an inst
34、allation and the associated process systems are sufficiently well understood, it is possible to use codes and standards as the basis for the hazard identification and risk assessment activities that underpin the selection of the required process protection systems. The content of this International
35、Standard is designed to be used for such applications and has been derived from the methods contained in API RP 14C 8that have proven to be effective for many years. Alternative methods of evaluation may be used, for example based on the structured review techniques described in ISO 17776. Having un
36、dertaken an appropriate evaluation, the selection of equipment to use may be based on a combination of the traditional prescriptive approach and new standards that are more risk based. Particular requirements for the control and mitigation of fires and explosions on offshore installations are given
37、in ISO 13702. General requirements for fire and gas and emergency shutdown (ESD) systems are also included in ISO 13702. This International Standard and ISO 13702 reference new standards on functional safety of instrumented systems. This International Standard refers to IEC 61511-1, which is the pro
38、cess sector implementation of the generic standard IEC 61508 that is referred to in ISO 13702. The relationship between the standards referred to above is presented in Figure 1. The approach described in this International Standard should be applied in an iterative way. As design proceeds, considera
39、tion should be given as to whether any new hazards are introduced and whether any new risk-reduction measures need to be introduced. It should be recognized that the design, analysis and testing techniques described in this International Standard have been developed bearing in mind the typical insta
40、llations now in use. Due consideration should therefore be given during the development of process protection systems to the size of the installation, the complexity of the process facilities, the complexity and diversity of the protection equipment and the manning levels required. New and innovativ
41、e technology may require new approaches. This International Standard has been prepared primarily to assist in the development of new installations, and as such it may not be appropriate to apply some of the requirements to existing installations. Retrospective application of this International Stand
42、ard should only be undertaken if it is reasonable to do so. During the planning of a major modification to an installation, there may be more opportunity to implement the requirements and a careful review of this International Standard should be undertaken to determine those clauses which can be ado
43、pted during the modification.

The basic concepts associated with the analysis and design of a process safety system for an offshore oil and gas production facility are described, together with examples of the application to typical (simple) process components. These examples are contained in the annexes of this International
46、 Standard. This International Standard is applicable to fixed offshore structures; floating production, storage and off-take systems; for the petroleum and natural gas industries. This International Standard is not applicable to mobile offshore units and subsea installations, although many of the pr
47、inciples contained in it may be used as guidance. 2 Normative references The following referenced documents are indispensable for the application of this document.
