EN ISO 19901-8:2015

Petroleum and natural gas industries - Specific requirements for offshore structures - Part 8: Marine soil investigations (ISO 19901-8:2014)

ISO 19901-8:2014 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 ISO 19901-8:2014 to the extent that ordinary marine soil investigation tools can be used, e.g. for chalk, calcareous soils, cemented soils or similar soft rock.
ISO 19901-8:2014 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.

Industries du pétrole et du gaz naturel - Exigences spécifiques relatives aux structures en mer - Partie 8: Investigations des sols en mer (ISO 19901-8:2014)

L'ISO 19901-8:2014 spécifie des exigences, des recommandations et des lignes directrices pour la reconnaissance des sols en mer, concernant :
a)    les objectifs, la planification et l'exécution de la reconnaissance des sols en mer ;
b)    le déploiement de l'équipement de reconnaissance ;
c)    le forage et la diagraphie ;
d)    les essais in situ ;
e)    l'échantillonnage ;
f)     les essais en laboratoire ; et
g)    l'établissement de rapports.
Les matériaux rocheux ne sont traités dans l'ISO 19901-8:2014 que dans la mesure où des outils ordinaires de reconnaissance des sols en mer peuvent être utilisés, par exemple pour les sols crayeux, calcaires, les sols consolidés ou une roche tendre similaire.

Industrija za predelavo nafte in zemeljskega plina - Posebne zahteve za naftne ploščadi - 8. del: Preiskave morskega dna (ISO 19901-8:2014)

Ta del standarda ISO 19901 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.
ISO 19901 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). Preiskave trdnih kamnitih materialov v tem delu standarda ISO 19901 niso obravnavane (za nadaljnje napotke glej F.13). Projektiranje temeljev ni obravnavano v tem delu standarda ISO 19901, temveč v standardu ISO 19901-4 in ustreznih standardih projektiranja za posebne vrste naftnih ploščadi, kot je navedeno v predgovoru in uvodu.
Načrtovanje, izvedba in interpretacija geofizičnih preiskav niso obravnavani v tem delu standarda ISO 19901. Vendar naj bi se rezultati geofizičnih preiskav uporabili za načrtovanje, optimizacijo in interpretacijo preiskav morskega dna, kjer je to primerno.
Ta del standarda ISO 19901 ne obravnava načrtovanja in področja uporabe študij geoloških nevarnosti, temveč samo ustrezne vidike preiskav morskega dna v okviru teh študij.
Ta del standarda ISO 19901 ne obravnava preiskav ledenega dna v arktičnih območjih.
Ta del standarda ISO 19901 je namenjen odjemalcem, izvajalcem preiskav dna, projektantom, izvajalcem namestitve, geotehničnim laboratorijem ter javnim in upravnim organom na področju
preiskav morskega dna za namene postavitve kakršnih koli konstrukcij na odprtem morju in ob obali ali opravljanje študij geoloških nevarnosti za naftno in plinsko industrijo.
