26、N ISO 19901-5:2016ISO 19901-5:2016(E)ForewordISO (the International Organization 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 i
27、nterested in a subject for which a technical committee has been established has 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 Electrotechn
28、ical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for 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 do
29、cuments should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held respons
30、ible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given fo
31、r the convenience of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the WTO principles in the Technical Barriers to Trade (TBT) see the following URL
32、: Foreword - Supplementary informationThe committee responsible for this document is ISO/TC 67, Materials,equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 7, Offshore structures.This second edition cancels and replaces the first edition (ISO
33、19901-5:2003), which has been technically revised.ISO 19901 consists of the following parts, under the general title Petroleum and natural gas industries Specific requirements for offshore structures: Part 1: Metocean design and operating considerations Part 2: Seismic design procedures and criteria
34、 Part 3: Topsides structure Part 4: Geotechnical and foundation design considerations Part 5: Weight control during engineering and construction Part 6: Marine operations Part 7: Stationkeeping systems for floating offshore structures and mobile offshore units Part 8: Marine soil investigationsThe f
35、ollowing parts are under preparation: Part 9: Structural integrity management ISO 2016 All rights reserved vBS EN ISO 19901-5:2016ISO 19901-5:2016(E)0 Introduction0.1 GeneralThe International Standards ISO 19900 to ISO 19906 relating to offshore structures constitute a common basis covering those as
36、pects that address design requirements and assessments of 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 unmanned offshore structures, whatever the type of structu
37、re and the nature 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, quality control procedures and national requirements, all of which are mutua
38、lly 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 be considered in relation to the overall reliability of all offshore struct
39、ural systems.ISO 19900 to ISO 19906 relating to offshore structures are intended to provide a wide latitude in the choice of structural configurations, materials and techniques without hindering innovation. Sound engineering judgement is therefore necessary in the use of these International Standard
40、s.0.2 PrefaceIt is proposed to canvass the TC 67/SC 7 member countries to widen the scope of this part of ISO 19901 for the third edition. As a consequence, the title might change. It is proposed to expand and re-structure this part of ISO 19901 to more comprehensively address topsides weight engine
41、ering principles, roles, responsibilities and objectives for a complete platform life cycle. It is proposed to re-format into a more traditional ISO document layout. The use of weight class A, B and C tables will be reviewed. There will be an outline of how to control topside weight, and of the aims
42、 and expectations of a Weight Review Panel (or similar). A common topside operating philosophy will be included with a matrix of coincident drilling loads, operating loads, and laydown / storage loads to be included in topside weight databases. It is proposed to give guidance on applied design contr
43、actor allowances during detailed design, plus the use of client operational and management reserves. The weight and CoG accuracy expected from weighings will be addressed. Separate clauses will be added to give clarity to specific requirements of floating structures and jackets The contents and term
44、inology will be coordinated to interface with ISO 19902, Design of offshore structures, and the forthcoming ISO19901-9, Structural integrity management (due to be published in 2017).It is proposed to give more guidance on a range of topics encountered during the phases of a platform life cycle, typi
