28、 for Standardization) is a worldwide federation of national 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
29、the right to be represented on that committee. International 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. Intern
30、ational Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publicati
31、on as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

36、he series of International Standards ISO 19900 to ISO 19906 addresses design requirements and assessments for all offshore structures used by the petroleum and natural gas industries worldwide. Through their application, the intention is to achieve reliability levels appropriate for manned and unman
37、ned offshore structures, regardless of the type of structure and the nature or combination of the materials used. It is important to recognize that structural integrity is an overall concept comprising models for describing actions, structural analyses, design rules, safety elements, workmanship, qu
38、ality control procedures and national requirements, all of which are mutually dependent. The modification of one aspect of design in isolation can disturb the balance of reliability inherent in the overall concept or structural system. The implications involved in modifications, therefore, need to b
39、e considered in relation to the overall reliability of all offshore structural systems. The series of International Standards applicable to the various types of offshore structure is intended to provide wide latitude in the choice of structural configurations, materials and techniques without hinder
40、ing innovation. Sound engineering judgment is, therefore, necessary in the use of these International Standards. This International Standard was developed in response to the offshore industrys demand for a coherent and consistent definition of methodologies to design, analyse and assess arctic and c
41、old region offshore structures of the class described in Clause 1. Structures capable of resisting ice have been in use in temperate regions for well over a century. These include bridge piers and navigation aids in ice-covered rivers and estuaries. In fact, bridge codes in cold countries have inclu
42、ded methods for ice loads dating back many decades. In more severe arctic and cold regions, ice resistant structures are more recent. But much experience has been gained commencing in the 1960s, and this knowledge is incorporated into this International Standard. Where uncertainties still exist, con
43、servative approaches and methods have been recommended. This International Standard also addresses issues such as topsides winterization, and escape, evacuation and rescue that go beyond what is strictly necessary for the design, construction, transportation, installation and decommissioning of the
44、structure. These issues are essential for offshore operations in arctic and cold region conditions and they are not covered in other International Standards. When future editions of ISO 19906 and other International Standards are prepared, efforts will be made to avoid duplication of scope. Annex A
45、provides background to and guidance on the use of this International Standard and it is intended that it be read in conjunction with the main body of this International Standard. The clause numbering in Annex A is the same as in the normative text to facilitate cross-referencing. Annex B provides re
46、gional information on the physical environment of specific offshore areas in arctic and cold regions. To meet certain needs of industry for linking software to specific elements in this International Standard, a special numbering system has been permitted for figures, tables, equations and bibliogra
47、phic references.

48、 design, construction, transportation, installation and removal of offshore structures, related to the activities of the petroleum and natural gas industries in arctic and cold regions. Reference to arctic and cold regions in this International Standard is deemed to include both the Arctic and other
49、 cold regions that are subject to similar sea ice, iceberg and icing conditions. The objective of this International Standard is to ensure that offshore structures in arctic and cold regions provide an appropriate level of reliability with respect to personnel safety, environmental protection and asset value to the owner, to the industry and to society in general. This International Standard does not contain requirements for the operation, maintenance, service-life inspection or repair of arctic and cold region offshore str
