标准范围
This document provides requirements and guidelines for marine geophysical investigations. It is
applicable to operators/end users, contractors and public and regulatory authorities concerned with
marine site investigations for offshore structures for petroleum and natural gas industries.
This document provides requirements, specifications, and guidance for:
a) objectives, planning, and quality management;
b) positioning;
c) seafloor mapping, including instrumentation and acquisition parameters, acquisition methods, and
deliverables;
d) sub-seafloor mapping, including seismic instrumentation and acquisition parameters, and non-
seismic-reflection methods;
e) reporting;
f) data integration, interpretation, and investigation of geohazards.
This document is applicable to investigation of the seafloor and the sub-seafloor, from shallow coastal
waters to water depths of 3 000 m and more. It provides guidance for the integration of the results from
marine soil investigations and marine geophysical investigations with other relevant datasets.
NOTE 1 The depth of interest for sub-seafloor mapping depends on the objectives of the investigation. For
offshore construction, the depths of investigation are typically in the range 1 m below seafloor to 200 m below
seafloor. Some methods for sub-seafloor mapping can also achieve much greater investigation depths, for
example for assessing geohazards for hydrocarbon well drilling.
