Ship and marine technology - Technical requirements for dry-disconnect/connect couplings for bunkering liquefied natural gas (ISO 21593:2019)

This document specifies the design, minimum safety, functional and marking requirements, as well as the interface types and dimensions and testing procedures for dry-disconnect/connect couplings for LNG hose bunkering systems intended for use on LNG bunkering ships, tank trucks and shore-based facilities and other bunkering infrastructures. It is not applicable to hydraulically operated quick connect/disconnect couplers (QCDC) used for hard loading arms, which is covered in ISO 16904.
Based on the technology used in industrial manufacturing at the time of development of this document, it is applicable to sizes of couplings ranging from DN 25 to DN 200.

Schiff- und Meerestechnik- Trockene Anschluss- und Trennkupplung(en) für das Bunkern flüssigerdgasbetriebener Schiffe (ISO 21593:2019)

Dieses Dokument legt Anforderungen für Konstruktion, minimale Sicherheit, für Funktion und Kennzeichnung, sowie Schnittstellentypen und Maße und Prüfverfahren für LNG Trockenkupplungen fest, die LNG Schlauchbunkersystemen dienen und für LNG Bunkerschiffe, Tanklastwagen und land-basierte Anlagen und andere Bunkerinfrastrukturen bestimmt sind. Es ist nicht anwendbar auf hydraulisch betätigte Schnellkupplungen (QCDC, en: Quick Connect/Disconnect Coupler), die für feste Verladearme Verwendung finden und in ISO 16904 abgedeckt sind.
Basierend auf der Technologie, die zum Zeitpunkt der Erstellung dieses Dokuments in der industriellen Fertigung verwendet wurde, ist es für Kupplungsgrößen von DN 25 bis DN 200 anwendbar.

Navires et technologie maritime - Exigences techniques relatives au couplage de connexion et de déconnexion à sec pour le soutage de gaz naturel liquéfié (ISO 21593:2019)

Ce document spécifie les exigences de conception, de sécurité minimale, de fonctionnement et de marquage, ainsi que les types et dimensions d'interface et les procédures d'essai applicables au couplage de connexion/déconnexion à sec de GNL utilisé pour un système de soutage de GNL par flexible, destiné à être utilisé sur un navire de soutage de GNL, un camion-citerne, une installation terrestre et les autres infrastructures de soutage. Il ne s'applique pas aux coupleurs de connexion et de déconnexion rapide à commande hydraulique (QCDC) utilisés pour un bras de chargement rigide, lesquels sont couverts par l'ISO 16904.
Compte tenu de la technologie actuelle de production industrielle au moment de l'élaboration de ce document, il est applicable aux tailles de coupleurs comprise entre DN25 et DN200.

Ladijska in pristaniška tehnologija - Tehnične zahteve za suhe spoje za priklop in odklop pri polnjenju plovil na utekočinjeni zemeljski plin (ISO 21593:2019)

Ta tehnični standard določa zahteve glede projektiranja, minimalne varnosti, delovanja in označevanja ter tudi vrste vmesnikov in mere ter preskusne postopke za suhe spoje za priklop in odklop pri cevnih sistemih za polnjenje utekočinjenega zemeljskega plina (LNG), namenjenih za uporabo na plovilih na utekočinjeni zemeljski plin, tovornjakih s cisternami ter priobalnih sistemih in drugih infrastrukturah za polnjenje. Ne uporablja se za hidravlično upravljane hitre spojke (QCDC), ki se uporabljajo za trdne prenosne roke, obravnavane v standardu ISO 16904. Na podlagi tehnologije, uporabljane pri industrijski proizvodnji v času priprave tega dokumenta, se uporablja za vse velikosti spojk od DN 25 do DN 200.
