41、for simpler installations, e.g. wellhead platforms with limited process facilities, 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, e
42、valuations undertaken for the original design may be deemed sufficient to determine the measures needed to manage hazardous events; EN ISO 17776:2002 Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 19 15:45:00 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 7 ?for installations in the early design ph
43、ases, 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 developed during these early stages need to be verified once the installation is operational. Hazar
44、d 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. 4.2Role of experience/judgement An often adequate approach is one in which the knowledge and expertise of staff, having
45、appropriate experience, is used for hazard identification and assessment. This is particularly useful where the activity under consideration is similar to activities undertaken previously at the same or different locations. Practical staff experience gained in the field and feedback from hazardous e
46、vents and near misses that have occurred is essential in this respect. This approach on its own, however, is unlikely to be sufficient when dealing with novel or innovative systems and facilities, or where local conditions render previous experience invalid. For example, operating experience gained
47、in benign tropical waters should not generally be used as the basis for evaluations of arctic installations. 4.3Checklists These are a useful way of ensuring that known hazards and threats have all been identified and assessed, although the use of checklists shall not be allowed to limit the scope o
48、f any review. Checklists are normally drawn up from standards and operational experience, and therefore focus on areas where the potential for mistakes is high or where problems have occurred in the past. Checklists are easy to apply and can be used at any stage in the project life cycle. The checkl
49、ist should be prepared by experienced personnel familiar with the design and operation of the facilities and with the company and industry standards and procedures. Checklists may be applied by less experienced personnel, although the effectiveness of the checklist technique is limited by the experience of the authors and the diligence of the users. However, they do not provide a creative format for the identification and evaluation of new hazards where experience is lacking. Checklists sh
