CSA Preface
This is the first edition of CAN/CSA-ISO 19901-8, Petroleum and natural gas industries — Specific requirements for offshore structures — Part 8: Marine soil investigations, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 19901-8 (first edition, 2014-12-01). At the time of publication, ISO 19901-8:2014 is available from ISO in English only. CSA Group 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 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 part of ISO 19901 specifies requirements, and provides recommendations and guidelines for marine soil investigations regarding:
a) objectives, planning and execution of marine soil investigations;
b) deployment of investigation equipment;
c) drilling and logging;
d) in situ testing;
e) sampling;
f) laboratory testing; and
g) reporting.
Rock materials are only covered by this part of ISO 19901 to the extent that ordinary marine soil investigation tools can be used, e.g. for chalk, calcareous soils, cemented soils or similar soft rock.
Hard rock investigations are not covered by this part of ISO 19901; see F1.3. for further guidance.
Foundation design is not covered by this part of ISO 19901, but by ISO 19901-4 and the respective design standards for the specific types of offshore structures as listed in the Foreword and Introduction.
Planning, execution and interpretation of geophysical investigations are not covered by this part of ISO 19901. However, the results from geophysical investigations should, where appropriate, be used for planning, optimization and interpretation of marine soil investigations.
This part of ISO 19901 does not cover the planning and scope of geohazard assessment studies, only the corresponding marine soil investigations aspects thereof.
Soil investigations from ice in Arctic regions are not covered by this part of ISO 19901.
This part of ISO 19901 is intended for clients, soil investigation contractors, designers, installation contractors, geotechnical laboratories and public and regulatory authorities concerned with marine soil investigations for any type of offshore and nearshore structures, or geohazard assessment studies, for petroleum and natural gas industries.
