Oil and gas industries including lower carbon energy - Offshore structures - Part 8: Marine soil investigations (ISO 19901-8:2023)
This document 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;
g) reporting.
Although this document focuses on investigations of soil, it also provides guidance, with less detail, for investigations of chalk, calcareous soils, cemented soils and weak rock.
Foundation design is not covered by this document.
NOTE 1 ISO 19901‑4 and the respective design standards covering foundation design for the specific types of offshore structures to meet the requirements of application specific standards are given on the ISO website.
The results from marine geophysical investigations are, when available and where appropriate, used for planning, optimization and interpretation of marine soil investigations.
This document neither covers the planning, execution and interpretation of marine geophysical investigations nor the planning and scope of geohazard assessment studies, only the corresponding marine soil investigations aspects thereof.
NOTE 2 ISO 19901-10 covers the planning, execution and interpretation of marine geophysical investigations.
This document specifies requirements and provides guidance for obtaining measured values and derived values. This document excludes requirements for determination of design values and representative values. Limited guidance is provided in 11.3 related to data interpretation.
This document 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 structures, or geohazard assessment studies.

d) les essais in situ;
e) l'échantillonnage;
f) les essais en laboratoire;
g) l'établissement de rapports.
Bien que le présent document se concentre sur les reconnaissances de sols, il fournit également des recommandations, moins détaillées, pour les reconnaissances des sols crayeux, des sols calcaires, des sols consolidés et des roches tendres.
La conception des fondations n'est pas traitée dans le présent document.
NOTE 1 L'ISO 19901-4 et les normes de conception respectives couvrant la conception des fondations pour les types spécifiques de structures en mer afin de répondre aux exigences des normes spécifiques à l'application sont données sur le site web de l'ISO.
Dans la mesure où ils sont disponibles et appropriés, les résultats des enquêtes géophysiques marines sont utilisés pour la planification, l'optimisation et l'interprétation de la reconnaissance des sols en mer.
Le présent document ne traite ni de la planification, de l'exécution et de l'interprétation des enquêtes géophysiques marines, ni de planification et de l'étendue des études d'évaluation des risques géologiques, mais couvre uniquement leurs aspects liés à la reconnaissance des sols en mer.
NOTE 2 L'ISO 19901-10 couvre la planification, l'exécution et l'interprétation des enquêtes géophysiques marines.
Le présent document spécifie des exigences et fournit des recommandations pour l'obtention de valeurs mesurées et de valeurs dérivées. Le présent document exclut les exigences relatives à la détermination des valeurs de calcul et des valeurs représentatives. Des recommandations limitées sont fournies en 11.3 en ce qui concerne l'interprétation des données.
Le présent document est destiné aux maîtres d'ouvrage, entreprises de reconnaissance des sols, concepteurs, entreprises d'installation, laboratoires géotechniques, autorités publiques et organismes de réglementation concernés par les reconnaissances des sols en mer pour tout type de structures installées au large, ou par les études d'évaluation des risques géologiques.
Naftna in plinska industrija, vključno z nizkoogljično energijo - Naftne ploščadi - 8. del: Preiskave morskega dna (ISO 19901-8:2023)
Standard ISO 19901-8:2014 določa zahteve ter podaja priporočila in smernice za preiskave morskega dna v povezavi z naslednjimi točkami:
a) cilji, načrtovanje in izvajanje preiskav morskega dna;
b) uvedba preiskovalne opreme;
c) vrtanje in beleženje;
d) preskušanje na mestu uporabe;
e) vzorčenje;
f) laboratorijsko preskušanje; in
g) poročanje.
Standard ISO 19901-8:2014 obravnava kamnite materiale samo v obsegu možnosti uporabe običajnih orodij za preiskave morskega dna (npr. orodje za obdelavo apnenca, karbonatnih površin, spojenih površin ali podobnih mehkih kamnin).
Standard ISO 19901-8:2014 je namenjen odjemalcem, izvajalcem preiskav dna, projektantom, izvajalcem namestitve, geotehničnim laboratorijem ter javnim in upravnim organom na področju preiskav morskega dna za namene postavitve različnih konstrukcij na odprtem morju in ob obali ali opravljanje študij geoloških nevarnosti za naftno in plinsko industrijo.
