21、of hydrocarbons1). These managementsystems should be applied to all stages in the life cycle of an installation and to all related activities. Such amanagement system, which has been developed for environmental issues, is described in ISO 140014andthe principles contained in this International Stand
22、ard can also be applied to issues relating to health andsafety.One key element of effective management systems is a systematic approach to the identification of hazardsand the assessment of the risk in order to provide information to aid decision-making on the need to introducerisk-reduction measure
23、s.Risk reduction is an important component of risk management, and the selection of risk-reduction measureswill predominantly entail the use of sound engineering judgement. However, such judgements may need to besupplemented by recognition of the particular circumstances, which may require variation
24、 to past practicesand previously applied codes and standards.Risk-reduction measures should include those to prevent incidents (i.e. reducing the probability ofoccurrence), to control incidents (i.e. limit the extent and duration of a hazardous event) and to mitigate theeffects (i.e. reducing the co
25、nsequences). Preventative measures such as using inherently safer designs andensuring asset integrity should be emphasized wherever practicable. Measures to recover from incidentsshould be provided based on risk assessment and should be developed taking into account possible failuresof the control a
26、nd mitigation measures. Based on the results of the evaluation, detailed health, safety andenvironmental objectives and functional requirements should be set at appropriate levels.The level and extent of hazard identification and risk assessment activities will vary depending on the scale ofthe inst
27、allation and the stage in the installation life cycle when the identification and assessment process isundertaken. For example:Gbe complex installations, e.g. a large production platform incorporating complex facilities, drilling modulesand large accommodation modules, are likely to require detailed
28、 studies to address hazardous eventssuch as fires, explosions, ship collisions, structural damage, etc.;Gbe for simpler installations, e.g. a wellhead platform with limited process facilities, it may be possible to relyon application of recognized codes and standards as a suitable base which reflect
29、s industry experiencefor this type of facility;Gbe for installations which are a repeat of earlier designs, evaluations undertaken for the original design maybe deemed sufficient to determine the measures needed to manage hazardous events;Gbe for installations in the early design phases, the evaluat
30、ions will necessarily be less detailed than thoseundertaken during later design phases and will focus on design issues rather than management andprocedural aspects. Any design criteria developed during these early stages will need to be verified oncethe installation is operational.Hazard identificat
31、ion and risk assessment activities may need to be reviewed and updated if significant newissues are identified or if there is significant change to the installation. The above is general and applies to allhazards and potentially hazardous events.1) For example, operators should have an effective man
32、agement system. Contractors should have either their ownmanagement system or conduct their activities consistently with the operators management system.B55EB1B3E14C22109E918E8EA43EDB30F09CC9B7EF8DD9NormCD - Stand 2007-03 EN ISO 10418:2003 (E)5Process protection system is a term used to describe the
33、equipment provided to prevent, mitigate or controlundesirable events in process equipment, and includes relief systems, instrumentation for alarm andshutdown, and emergency support systems. Process protection systems should be provided based on anevaluation that takes into account undesirable events
34、 that may pose a safety risk. The results of theevaluation process and the decisions taken with respect to the need for process protection systems should befully recorded.If an installation and the associated process systems are sufficiently well understood, it is possible to usecodes and standards
35、as the basis for the hazard identification and risk assessment activities that underpin theselection of the required process protection systems. The content of this International Standard is designed tobe used for such applications and has been derived from the methods contained in API RP 14C8that h
36、aveproven to be effective for many years. Alternative methods of evaluation may be used, for example based onthe structured review techniques described in ISO 17776. Having undertaken an appropriate evaluation, theselection of equipment to use may be based on a combination of the traditional prescri
37、ptive approach and newstandards that are more risk based.Particular requirements for the control and mitigation of fires and explosions on offshore installations are givenin ISO 13702. General requirements for fire and gas and emergency shutdown (ESD) systems are alsoincluded in ISO 13702.This Inter
38、national Standard and ISO 13702 reference new standards on functional safety of instrumentedsystems. This International Standard refers to IEC 61511-1, which is the process sector implementation of thegeneric standard IEC 61508 that is referred to in ISO 13702. The relationship between the standards
39、 referredto above is presented in Figure 1.The approach described in this International Standard should be applied in an iterative way. As designproceeds, consideration should be given as to whether any new hazards are introduced and whether any newrisk-reduction measures need to be introduced.It sh
40、ould be recognized that the design, analysis and testing techniques described in this InternationalStandard have been developed bearing in mind the typical installations now in use. Due consideration shouldtherefore be given during the development of process protection systems to the size of the ins
41、tallation, thecomplexity of the process facilities, the complexity and diversity of the protection equipment and the manninglevels required. New and innovative technology may require new approaches.This International Standard has been prepared primarily to assist in the development of new installati
42、ons, andas such it may not be appropriate to apply some of the requirements to existing installations. Retrospectiveapplication of this International Standard should only be undertaken if it is reasonable to do so. During theplanning of a major modification to an installation, there may be more oppo
43、rtunity to implement therequirements and a careful review of this International Standard should be undertaken to determine thoseclauses which can be adopted during the modification.B55EB1B3E14C22109E918E8EA43EDB30F09CC9B7EF8DD9NormCD - Stand 2007-03 EN ISO 10418:2003 (E)6Key1 Tools and techniques fo
