Petroleum and natural gas industries - Arctic offshore structures (ISO 19906:2019)
This document specifies requirements and provides recommendations and guidance for the design, construction, transportation, installation and decommissioning of offshore structures related to the activities of the petroleum and natural gas industries in arctic and cold regions. Reference to arctic and cold regions in this document is deemed to include both the Arctic and other locations characterized by low ambient temperatures and the presence or possibility of sea ice, icebergs, icing conditions, persistent snow cover, and/or permafrost. The objective of this document is to ensure that complete structures, including substructures, topsides structures, floating production vessel hulls, foundations and mooring systems, in arctic and cold regions provide an appropriate level of reliability with respect to personnel safety, environmental protection and asset value. Value includes value to the owner, to the industry and to society in general. This document does not contain requirements for the operation, maintenance, service-life inspection or repair of arctic and cold region offshore structures, unless the design strategy imposes specific requirements such as ice management (IM) to reduce ice actions. Provisions for the operation, maintenance, service-life inspection and repair of mobile units are given in ISO 19905-1 and ISO 19905-3, supplemented by the provisions relating to ice actions and IM in this document. This document does not apply to mechanical, process and electrical equipment or any specialized process equipment associated with arctic and cold region offshore operations except in so far as it is necessary for the structure to sustain safely the actions imposed by the installation, housing and operation of such equipment. This document applies to equipment used for the positioning and disconnection of floating structures (see Clause 13).

Industrija nafte in zemeljskega plina - Naftne ploščadi za arktična območja (ISO 19906:2019)
Ta dokument določa zahteve ter podaja priporočila in smernice glede načrtovanja, transporta, namestitve in izločitve iz uporabe za naftne ploščadi v zvezi z dejavnostmi naftne industrije in industrije zemeljskega plina v arktičnih in hladnih območjih. Sklic na arktična in hladna območja v tem dokumentu vključuje Arktiko in druge lokacije, katerih značilnost so nizke temperature okolice ter prisotnost ali možnost nastanka ledu, ledenih gora, zaledenitve, trajne snežne odeje in/ali permafrosta. Cilj tega dokumenta je zagotoviti, da celotne strukture, vključno s podstrukturami, strukturami na palubi, plavajočimi proizvodnimi plovili, temelji in sistemi zasidranja, v arktičnih in hladnih območjih zagotavljajo ustrezno raven zanesljivosti v zvezi z osebno varnostjo, varstvom okolja in vrednostjo premoženja. Vrednost vključuje vrednost za lastnika, industrijo in družbo na splošno. Ta dokument ne vključuje zahtev za obratovanje, vzdrževanje, preglede in popravila med obratovanjem naftnih ploščadi v arktičnih in hladnih območjih, če strategija zasnove ne nalaga posebnih zahtev, kot je ravnanje v primeru ledu (IM) za zmanjšanje vplivov ledu. Določila glede obratovanja, vzdrževanja, pregledov in popravil med obratovanjem mobilnih enot so podana v standardih ISO 19905-1 in ISO 19905-3, dopolnjujejo pa jih določila v zvezi z vplivi ledu in ravnanjem v primeru ledu v tem dokumentu. Ta dokument se ne uporablja za mehansko, procesno in električno opremo ali nobeno specializirano procesno opremo, povezano z obratovanjem ploščadi v arktičnih in hladnih območjih, razen kolikor je to potrebno, da struktura varno vzdrži vse vplive zaradi namestitve, ohišja in obratovanja takšne opreme. Ta dokument se uporablja za opremo za pozicioniranje in odklop plavajočih struktur (glej točko 13).
