Petroleum and natural gas industries - Design and testing of LNG marine transfer arms for conventional onshore terminals (ISO 16904:2016)

ISO 16904:2016 specifies the design, minimum safety requirements and inspection and testing procedures for liquefied natural gas (LNG) marine transfer arms intended for use on conventional onshore LNG terminals, handling LNG carriers engaged in international trade. It can provide guidance for offshore and coastal operations. It also covers the minimum requirements for safe LNG transfer between ship and shore.
Although the requirements for power/control systems are covered, this International Standard does not include all the details for the design and fabrication of standard parts and fittings associated with transfer arms.
ISO 16904:2016 is supplementary to local or national standards and regulations and is additional to the requirements of ISO 28460.
ISO 16904:2016 needs not be applied to existing facilities.

Erdöl- und Erdgasindustrie - Auslegung und Prüfung von Schiffsverladearmen für Flüssigerdgas für konventionelle landseitige Terminals (ISO 16904:2016)

Diese Internationale Norm legt die Auslegung, die Mindestanforderungen an die Sicherheit und die Kontroll- und Prüfverfahren für Schiffsverladearme für Flüssigerdgas (LNG, en: Liquified Natural Gas) fest, die für den Gebrauch auf konventionellen landseitigen LNG-Terminals vorgesehen sind, an denen LNG Tanker für den internationalen Handel abgefertigt werden. Diese Norm enthält auch die Mindestanforderungen für den sicheren Umschlag von Flüssigerdgas zwischen Schiff und Land.
Obgleich die Anforderungen an Stromversorgungs- und Steuerungssysteme aufgeführt sind, gibt das Dokument nicht alle Einzelheiten für die Auslegung und Herstellung von genormten Teilen und Armaturen für Ladearme an.
Diese Internationale Norm gilt zusätzlich zu lokalen oder nationalen Normen und Verordnungen und ergänzt die Anforderungen der ISO 28460.
Diese Internationale Norm gilt nicht für bestehende Anlagen.

Industries du pétrole et du gaz naturel - Conception et essais des bras de transfert de GNL sur des terminaux terrestres conventionnels (ISO 16904:2016)

L'ISO 16904:2016 spécifie les règles de conception, les spécifications minimales de sécurité ainsi que les procédures de contrôle et d'essais relatifs aux bras de transfert de gaz naturel liquéfié (GNL) marins destinés à être utilisés sur des terminaux terrestres conventionnels, recevant des méthaniers engagés dans le commerce international. Elle peut fournir des lignes directrices pour des opérations côtières et au large. Elle fixe également les spécifications minimales permettant de garantir que le transfert de GNL entre le navire et le terminal s'effectue en toute sécurité.
Bien que les spécifications relatives aux systèmes d'alimentation/télécommande soient couvertes, l'ISO 16904:2016 ne fixe pas tous les détails relatifs à la conception et à la fabrication des pièces normalisées et des raccords des bras de transfert.
L'ISO 16904:2016 vient compléter les normes et règlements locaux ou nationaux, et s'ajoute aux spécifications de l'ISO 28460.
Il n'est pas nécessaire d'appliquer l'ISO 16904:2016 aux installations existantes.

Industrija nafte in zemeljskega plina - Načrtovanje in preskušanje rok za pretakanje utekočinjenega zemeljskega plina za konvencionalne terminale na kopnem (ISO 16904:2016)

Ta evropski standard določa načrtovanje, minimalne varnostne zahteve in preglede ter preskusne postopke za prenos utekočinjenega zemeljskega plina (LNG), namenjenega za rabo na konvencionalnih kopenskih LNG-terminalih 1. Ta standard zajema tudi minimalne zahteve za varen prenos utekočinjenega zemeljskega plina med ladjo in obalo. Kljub temu, da standard zajema tudi zahteve za daljinsko vodene napajalne sisteme, ne zajema vseh podrobnosti glede načrtovanja in izdelave standardnih delov in pritrdilnih elementov, povezanih z sistemom prenosa. Vsebina tega evropskega standarda dopolnjuje lokalne ali nacionalne standarde in predpise ter je dodatek k zahtevam iz standardov EN 1532 in EN 1473.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).
