The work of preparing International Standards is normally carried out through ISO
28、 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 cl
29、osely 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
30、 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 pat

34、AL STANDARD ISO 16904:2016(E)Petroleum and natural gas industries Design and testing of LNG marine transfer arms for conventional onshore terminals1 ScopeThis International Standard specifies the design, minimum safety requirements and inspection and testing procedures for liquefied natural gas (LNG
35、) 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 requirem
36、ents 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.This International Standard is supplementary to local or national standards and regulations and is addi
37、tional to the requirements of ISO 28460.This International Standard needs not be applied to existing facilities.2 Normative referencesThe following referenced documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
