16、7177:2015 ISO/TR 17177:2015(E) 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 intere

17、sted 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

18、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 docume

19、nts 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 responsibl

ISO 2015 All rights reserved v PD ISO/TR 17177:2015 ISO/TR 17177:2015(E) Introduction The recent expan

23、sion of the LNG industry has led to the development of marine LNG facilities and transfer systems that differ from conventional LNG facility designs. These LNG transfer facilities can require additional or alternative systems and/or operational procedures to enable their safe operation. This Technic

24、al Report is intended to provide guidance for aspects of these facilities not covered by current standards and guidelines.vi ISO 2015 All rights reserved PD ISO/TR 17177:2015 Petroleum and natural gas industries Guidelines for the marine interfaces of hybrid LNG terminals 1 Scope This Technical Repo

25、rt provides guidance for installations, equipment and operation at the ship to terminal and ship to ship interface for hybrid floating and fixed LNG terminals that might not comply with the description of “Conventional LNG Terminal” included in ISO 28460. This Technical Report is intended to be read

26、 in conjunction with ISO 28460 to ensure the safe and efficient LNG transfer operation at these marine facilities. This Technical Report also addresses high pressure natural gas (HPNG) at the transfer interface at facilities where liquefaction or regasification is undertaken, but does not describe r

27、equirements for the process plant generally forming part of the terminal facility. These guidelines are based around facilities that are currently in operation or under development. 2 T erms, d efinitions , and abbr e viat ed t erms 2.1 T erms and definiti ons For the purposes of this document, the
