28、 standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical 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. Internationa
29、l organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended fo
30、r its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for 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.o

ISO 2016 All rights reserved vBS EN ISO 17776:2016ISO 17776:2016(E)IntroductionThe purpose of this document is to establish requirements and provide guida
36、nce for the effective management of major accident (MA) hazards during the design of new offshore installations for the petroleum and natural gas industries.The management of MA hazards involves the application of engineering expertise and knowledge to provide the measures needed to meet the objecti
37、ves set by the organizations involved in the project development. A range of tools for evaluating and assessing the likelihood and consequences of MAs is needed to help select the measures to be implemented, and to judge when sufficient measures have been provided.This process is built on the underl
38、ying integrity provided by the application of internationally recognized codes and standards.This document covers the following main elements: establishing general requirements for identifying MA hazards and their causes; assessing MA hazards to understand their likelihood and possible consequences;
39、 developing suitable strategies for managing MA hazards; progressively improving the understanding of MA hazards and their consequences to guide design decisions during the development phases of the installation; providing the measures needed to manage all credible MAs; maintaining the measures thro
40、ughout the life of the installation.The technical content of this document is arranged as follows:a) objectives: the goals to be achieved;b) functional requirements: specifying requirements considered necessary to meet the stated objectives;c) annexes: guidelines in support of the functional require
41、ments.This document should be read in conjunction with ISO 13702 and ISO 15544.vi ISO 2016 All rights reservedBS EN ISO 17776:2016Petroleum and natural gas industries Offshore production installations Major accident hazard management during the design of new installations1 ScopeThis document describ
42、es processes for managing major accident (MA) hazards during the design of offshore oil and gas production installations. It provides requirements and guidance on the development of strategies both to prevent the occurrence of MAs and to limit the possible consequences. It also contains some require
43、ments and guidance on managing MA hazards in operation.This document is applicable to the design of fixed offshore structures, and floating systems for production, storage and offloadingfor the petroleum and natural gas industries.The scope includes all credible MA hazards with the potential to have
44、 a material effect on people, the environment and assets.This document is intended for the larger projects undertaken to develop new offshore installations. However, the principles are also applicable to small or simple projects or design changes to existing facilities and can also be relevant to on
45、shore production facilities.Mobile offshore units as defined in this document are excluded, although many of the principles can be used as guidance. The design of subsea facilities are also excluded, though the effects of mobile and subsea facilities are considered if they can lead to major accident
46、s that affect an offshore installation. This document does not cover the construction, commissioning, abandonment or security risks associated with offshore installations.The decision to apply the requirements and guidance of this document, in full or in part, is intended to be based on an assessmen
47、t of the likelihood and possible consequences of MA hazards.2 Normative referencesThe following documents are referred to in text in such a way that some or all of their content constitutes requirements of this document.
