CSA Preface 

This is the second edition of CSA ISO 19903, Petroleum and natural gas industries - Concrete offshore structures , which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 19903 (second edition, 2019-08). It supersedes the previous edition, published in 2007 as CAN/CSA-ISO 19903 (adopted ISO 19903:2006). For brevity, this Standard will be referred to as "CSA ISO 19903" throughout. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. 

Scope 

This document specifies requirements and provides recommendations applicable to fixed, floating and grounded concrete offshore structures for the petroleum and natural gas industries and for structures supporting nationally-important power generation, transmission or distribution facility. This document specifically addresses - the design, construction, transportation and installation of new structures, including requirements for in-service inspection and possible removal of structures, - the assessment of structures in service, and - the assessment of structures for reuse at other locations. This document is intended to cover the engineering processes needed for the major engineering disciplines to establish a facility for offshore operation.
