Preface<\/strong><\/p>\n

This is the second edition of CAN\/CSA-ISO 19901-4, Petroleum and natural gas industries – Specific requirements for offshore structures – Part 4: Geotechnical and foundation design considerations, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 19901-4 (second edition, 2016-07-15). It supersedes the previous edition published in 2006 as CAN\/CSA-ISO 19901-4 (adopted ISO 19901-4:2003). At the time of publication, ISO 19901-4:2016 is available from ISO in English only. CSA will publish the French version when it becomes available from ISO. <\/p>\n

For brevity, this Standard will be referred to as CAN\/CSA-ISO 19901-4 throughout. <\/p>\n

This Standard specifies that the resistance of foundations be computed either by applying a material factor to the soil strength or a resistance factor to the foundation capacity. The methodologies are two variations of partial factor design and are accepted in different parts of the world. However, experience with design codes in Canada (in which both approaches have been tried and tested) has resulted in adoption of the resistance factor approach in general practice. Designers are encouraged to use the methods proposed in this Standard to harmonize Canadian and international practice. Adoption of material factors requires practitioners to use sound engineering judgment, precedent, and their own experience to obtain a similar design outcome. <\/p>\n

Scope<\/strong><\/p>\n

This part of ISO 19901 contains provisions for those aspects of geoscience and foundation engineering that are applicable to a broad range of offshore structures, rather than to a particular structure type. Such aspects are: <\/p>\n
