3、e No. 1 ABSGUIDE FOR BUILDING AND CLASSING SUBSEA RISER SYSTEMS .2006 iii Foreword Foreword Foreword This Guide applies to classification of design, construction and installation of risers for offshore and marine applications, as well as the periodic surveys required for maintenance of classificatio

4、n. Serviceability of risers is also addressed, but only to the extent that proper functioning of the pipe and its components affects safety. This Guide may also be used for certification or verification of design, construction or installation of risers. ABS will certify or verify design, constructio

5、n and installation of offshore risers when requested by the Owner or mandated by government regulations to verify compliance with this Guide, a set of specific requirements, national standards or other applicable industry standards. If ABS certification or verification is in accordance with this Gui

6、de and covers design, construction and installation, then the riser is also eligible for ABS classification. This Guide has been written for worldwide application, and as such, the satisfaction of individual requirements may require comprehensive data, analyses and plans to demonstrate adequacy. Thi

7、s especially applies for risers located in frontier areas, such as those characterized by relatively great water depth or areas with little or no previous operating experience. Conversely, many provisions of this Guide often can be satisfied merely on a comparative basis of local conditions or past

8、successful practices. ABS acknowledges that a wide latitude exists as to the extent and type of documentation which is required for submission to satisfy this Guide. It is not the intention of this Guide to impose requirements or practices in addition to those that have previously proven satisfactor

9、y in similar situations. Where available, design requirements in this Guide have been posed in terms of existing methodologies and their attendant safety factors, load factors or permissible stresses that are deemed to provide an adequate level of safety. Primarily, ABSs use of such methods and limi

10、ts in this Guide reflects what is considered to be the current state of practice in offshore riser design. At the same time, it is acknowledged that new materials and methods of design, construction and installation are constantly evolving. The application of this Guide by ABS will not seek to inhib

11、it the use of any technological approach that can be shown to produce an acceptable level of safety. This ABS Guide is effective 1 May 2006 and supersedes the edition published in May 2005. This edition adds an Appendix for the design, testing and installation of composite risers. Changes to Conditi

12、ons of Classification (1 January 2008) For the 2008 edition, Chapter 1, “Scope and Conditions of Classification” was consolidated into a generic booklet, entitled Rules for Conditions of Classification Offshore Units and Structures (Part 1) for all units, installations, vessels or systems in offshor

13、e service. The purpose of this consolidation was to emphasize the common applicability of the classification requirements in “Chapter 1” to ABS-classed offshore units, pipelines, risers, and other offshore structures, and thereby make “Conditions of Classification” more readily a common Rule of the

14、various ABS Rules and Guides, as appropriate. Thus, Chapter 1 of this Guide specifies only the unique requirements applicable to subsea riser systems. These supplemental requirements are always to be used with the aforementioned Rules for Conditions of Classification Offshore Units and Structures (P
