29、structures for petroleum and natural gas industries“ in collaboration with Technical Committee CEN/TC 12 “Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries“, the secretariat of which is held by AFNOR. This European Standard shall be given the status

30、 of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2007, and conflicting national standards shall be withdrawn at the latest by May 2007.

33、ndards applicable to types of offshore structure, ISO 19900 to ISO 19906, constitutes a common basis covering those aspects that address design requirements and assessments of all offshore structures used by the petroleum, petrochemical and natural gas industries worldwide. Through their application

34、 the intention is to achieve reliability levels appropriate for manned and unmanned offshore structures, whatever the type of structure and the nature or combination of materials used. It is important to recognize that structural integrity is an overall concept comprising models for describing actio

35、ns, structural analyses, design rules, safety elements, workmanship, quality 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 s

36、ystem. The implications involved in modifications, therefore, need to be considered in relation to the overall reliability of all offshore structural systems. The series of International Standards applicable to types of offshore structure is intended to provide wide latitude in the choice of structu

37、ral configurations, materials and techniques without hindering innovation. Sound engineering judgement is therefore necessary in the use of these International Standards. International Standard ISO 19904 was developed in response to the offshore industrys demand for a coherent and consistent definit

38、ion of methodologies to design, analyse and assess floating offshore structures of the class described in Clause 1. In particular, this part of ISO 19904 addresses monohulls, semi-submersibles and spars. Some background to, and guidance on, the use of this part of ISO 19904 is provided in informativ

39、e Annex A. The clause numbering in Annex A is the same as in the normative text to facilitate cross-referencing. B55EB1B3E14C22109E918E8EA43EDB30F09CC9B7EF8DD9NormCD - Stand 2007-03 EN ISO 19904-1:2006 (E) 7 1 Scope This part of ISO 19904 provides requirements and guidance for the structural design

40、and/or assessment of floating offshore platforms used by the petroleum and natural gas industries to support the following functions: production; storage and/or offloading; drilling and production; production, storage and offloading; drilling, production, storage and offloading. NOTE 1 Floating offs

41、hore platforms are often referred to using a variety of abbreviations, e.g. FPS, FSU, FPSO, etc. (see Clauses 3 and 4), in accordance with their intended mission. NOTE 2 In this part of ISO 19904, the term floating structure, sometimes shortened to structure, is used as a generic term to indicate th

42、e structural systems of any member of the classes of platforms defined above. NOTE 3 In some cases, floating platforms are designated as early production platforms. This term relates merely to an asset development strategy. For the purposes of this International Standard, the term production include

43、s early production. Its requirements do not apply to the structural systems of mobile offshore units (MOUs). These include, among others: floating structures intended primarily to perform drilling and/or well intervention operations (often referred to as MODUs), even when used for extended well test

44、 operations; floating structures used for offshore construction operations (e.g. crane barges or pipelay barges), for temporary or permanent offshore living quarters (floatels), or for transport of equipment or products (e.g. transportation barges, cargo barges), for which structures reference is ma

45、de to relevant recognized classification society (RCS) rules. Its requirements are applicable to all possible life-cycle stages of the structures defined above, such as design, construction and installation of new structures, including requirements for inspection, integrity management and future removal, structural integrity management covering inspection and assessment of structures in-service, and conversion of structures for differ
