3、onal foreword This British Standard is the English language version of EN ISO 13819-1:1997. It is identical with ISO 13819-1:1995. The UK participation in its preparation was entrusted by Technical Committee B/525, Building and civil engineering structures, to Subcommittee B/525/12, Design of offsho
4、re structures, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments
5、and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications
6、 with their corresponding European publications. The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” fac

24、SI 04-1999iii Foreword ISO (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 interested in a subject
25、 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 Electrotechnical Commission (IEC)
26、on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standar
27、d ISO 13819-1 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum and natural gas industries, Subcommittee SC 7, Offshore structures. ISO 13819 will consist of the following parts, under the general title Petroleum and natural gas industries Offs

30、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 mutually dependent. The modifications of one aspect of design in isolation can disturb the balance o
31、f 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 structural systems. International Standard ISO 13819 constitutes a common basis covering those aspec
32、ts that address design requirements and assessments of all structures used by the petroleum and natural gas industries worldwide. Through its application the intention is to achieve reliability levels appropriate for manned and unmanned offshore structures, whatever the nature or combination of the
33、materials used. ISO 13819 is intended to provide a wide latitude in the choice of structural, configurations, materials and techniques without hindering innovation. It shall, therefore, be used in conjunction with sound engineering judgment. Part 1 of ISO 13819 applies to offshore structures and is
34、in accordance with the principles of ISO 2394:1986, General principles on reliability for structures. It includes, where appropriate, additional provisions that are specific to offshore structures. 1 Scope Part 1 of the Standard specifies general principles for the design and assessment of structure
35、s subjected to known or foreseeable types of actions. The principles specified are applicable worldwide. The general principles are applicable to all types of offshore structures including bottom founded structures as well as floating structures. The general principles are applicable to all types of
36、 materials used including steel, concrete, aluminum, etc. The Standard is applicable to the design of complete structures including substructures, topside structures, vessel hulls, foundations, and mooring systems. The Standard specifies design principles that are also applicable to the successive s
37、tages in construction (namely fabrication, transportation and installation), to the use of the structure during its intended life, and to its abandonment. Generally, the principles are also applicable to the reassessment or modification of existing structures. Aspects related to quality control are
38、also addressed. NOTEThe term “action” was introduced into ISO terminology to cover the effects due to imposed deformation as well as loads. The term “load”, which is prevalent in some countries, can generally be used with essentially the same meaning as “action”. In the past, “load” has often been u
39、sed to describe direct actions only (see Clause 5.2.1). 2 Definitions For the purposes of this International Standard, the following definitions apply: 2.1 air gap the clearance between the highest water surface that occurs during the extreme environmental conditions and the underside of the deck 2.
40、2 compliant structure a structure that is sufficiently flexible, such that applied lateral dynamic actions can be balanced substantially by the inertial reaction 2.3 fitness for purpose a structure condition describing a structure that meets the intent of this Standard, but does not meet certain pro
41、visions of this standard in local areas, such that failure in these areas will not cause unacceptable risks to life-safety or the environment 2.4 fixed structure a structure that is bottom founded and transfers all actions that act upon it to the sea floor 2.5 jack-up a mobile unit that can be reloc
42、ated and is bottom founded in its operating mode. The jack-up reaches its operational mode by lowering the legs to the sea floor and then jacking the hull to the required elevation 2.6 return period the average time (usually years) between occurrence of events or actions of a specified magnitude or
43、larger Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 19 15:34:18 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN ISO 13819-1:1997 2 BSI 04-1999 2.7 riser the piping connecting the facilities or piping on the production deck with the subsea facilities or pipelines 2.8 semi-submersible a floating
44、unit that can be relocated. A semi-submersible normally consists of a deck structure with a number of widely spaced, large diameter, supporting columns that are attached to submerged pontoons 2.9 tension leg platform a buoyant structure that is anchored to the sea floor by vertical mooring legs 2.10
45、 well conductor a tubular pipe extending upward from the sea floor (or below) that contains the pipes (casing) that extend into the petroleum reservoir 3 General requirements and conditions NOTEThe requirements and conditions set forth in this section define the objective of the design. Criteria to
46、enable designers and builders to reach this goal are provided throughout this Standard. However, unforeseen events that cause a structure to not achieve its objectives during its service life does not automatically imply a lack of compliance with this Standard. 3.1 Fundamental requirements A structu
47、re and its structural components shall be designed, constructed, and maintained so that it is suited to its intended use. In particular, it shall, with appropriate degrees of reliability, fulfill the following performance requirements: a) It shall withstand actions liable to occur during its constru
48、ction and anticipated use (ultimate limit state requirement). b) It shall perform adequately under all expected actions (serviceability limit state requirement). c) It shall not fail under repeated actions (fatigue limit state). d) In the case of hazards (accidental or abnormal events), it shall not
49、 be subsequently damaged disproportionately to the original cause (accidental limit state). e) Appropriate degrees of reliability may depend upon: the cause and mode of failure the possible consequences of failure in terms of risk to life, environment and property the expense and effort required to reduce the risk of failure different requirements at national, regional or local level This standard is set forth to provide criteria so that the above requirements are fulfilled during the intended life of the structure.
