Petroleum and natural gas industries - Fixed concrete offshore structures (Adopted ISO 19903:2006, first edition, 2006-12-01)
This is the first edition of CAN/CSA-ISO 19903, Petroleum and natural gas industries — Fixed concrete offshore structures, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 19903:2006 (first edition, 2006-12-01). At the time of publication, ISO 19903:2006 is available from ISO in English only. CSA will publish the French version when it becomes available from ISO.
Standards development within the Canadian Offshore Structures sector is harmonized with international standards development.
This Standard was reviewed for Canadian adoption by the harmonized Canadian Advisory Committee and the CSA Technical Committee to ISO/TC 67/SC 7, Offshore Structures. This Standard has been formally approved by the CSA Technical Committee on Design, Construction, and Installation of Offshore Structures under the jurisdiction of the Strategic Steering Committee of Offshore Structures. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada.
This International Standard specifies requirements and provides recommendations applicable to fixed concrete offshore structures for the petroleum and natural gas industries, and specifically addresses
a) the design, construction, transportation and installation of new structures, including requirements for in-service inspection and possible removal of structures
b) the assessment of structures in service, and
c) the assessment of structures for reuse at other locations.
This International Standard is intended to cover the engineering processes needed for the major engineering disciplines to establish a facility for offshore operation. It can also be used for the design of floating concrete structures as specified in ISO 19904-1  (and the future ISO 19904-2  when published) and for arctic structures (as specified in the future ISO 19906  when published).
In order to provide a standard that will be useful to the industry, a comprehensive treatment of some topics is provided where there is currently no relevant reference. For such well-known topics as the design formulas for concrete structural members, this International Standard is intended to be used in conjunction with a suitable reference standard for basic concrete design (see 8.2.1). The designer can use suitable national or regional design standards that provide the required level of safety. Only other ISO documents will be referenced directly in the text.
