3、 Notice No. 1 ABSGUIDE FOR BUILDING AND CLASSING SUBSEA PIPELINE SYSTEMS .2006 iii Foreword Foreword Foreword This Guide applies to classification of design, construction and installation of offshore pipelines made of metallic materials, as well as the periodic surveys required for maintenance of cl

4、assification. Serviceability of pipelines 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 and installation of pipelines. ABS will certify or verify d

5、esign, construction and installation of offshore pipelines 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 acc

6、ordance with this Guide and covers design, construction and installation, then the pipeline 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 d

7、emonstrate adequacy. This especially applies for pipelines 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 o

8、f local conditions or past 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 pr

9、eviously proven satisfactory 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 u

10、se of such methods and limits in this Guide reflects what is considered to be the current state of practice in offshore pipeline design. At the same time, it is acknowledged that methods of design, construction and installation are constantly evolving. In recognition of these facts, the Guide specif

11、ically allows for such innovations and the Appendices are intended to reflect this. The application of this Guide by ABS will not seek to inhibit 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 th

12、e edition published in May 2005. Changes to Conditions 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

13、units, installations, vessels or systems in offshore 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

14、 Classification” more readily a common Rule of the various ABS Rules and Guides, as appropriate. Thus, Chapter 1 of this Guide specifies only the unique requirements applicable to subsea pipeline systems. These supplemental requirements are always to be used with the aforementioned Rules for Conditi

15、ons of Classification Offshore Units and Structures (Part 1). iv ABSGUIDE FOR BUILDING AND CLASSING SUBSEA PIPELINE SYSTEMS .2006 Table of Contents GUIDE FOR BUILDING AND CLASSING SUBSEA PIPELINE SYSTEMS CONTENTS CHAPTER 1 Scope and Conditions of Classification (Supplement to the ABS Rules for Condi

32、 documentation for design, fabrication, installation and maintenance of offshore production, transfer and export pipelines made of metallic materials. The principal objectives are to specify the minimum requirements for classing, continuance of classing, certification and verification by ABS. In add

33、ition to the requirements of this Guide, the design of a marine system requires consideration of all relevant factors related to its functional requirements and long term integrity, such as: Compliance with local Laws, Acts and Regulations Functional requirements Physical site information Operationa

34、l requirements 1 Classification (1 January 2008) The requirements for conditions of classification are contained in the separate, generic ABS Rules for Conditions of Classification Offshore Units and Structures (Part 1). Additional requirements specific to subsea pipeline systems are contained in th

35、e following Sections. 4 ABSGUIDE FOR SURVEYS USING RISK-BASED INSPECTION FOR THE OFFSHORE INDUSTRY .2003 Section 2: Classification Symbols and Notations CHAPTER 1 Scope and Conditions of Classification SECTION 2 Classification Symbols and Notations (1 January 2008) A listing of Classification Symbol

36、s and Notations available to the Owners of vessels, offshore drilling and production units and other marine structures and systems, “List of ABS Notations and Symbols” is available from the ABS website “http:/www.eagle.org/absdownloads/index.cfm”. The following notations are specific to subsea pipel

37、ine systems. 1 Pipelines Built under Survey Pipelines which have been built, installed, tested and commissioned to the satisfaction of the ABS Surveyors to the full requirements of this Guide or to its equivalent, where approved by the Committee, will be classed and distinguished in the Record by: n

38、ull A1 Offshore Installation Offshore Pipelines 3 Pipelines not Built under Survey Pipelines which have not been built, installed, tested and commissioned under ABS survey, but which are submitted for classification, will be subjected to a special classification survey. Where found satisfactory, and

39、 thereafter approved by the Committee, they will be classed and distinguished in the Record in the manner as described in 1-2/1, but the mark null signifying survey during construction will be omitted. 5 Classification Data Data on the pipeline will be published in the Record as to the latitude and

40、longitude of its location, type, dimensions and depth of water at the site. ABSGUIDE FOR BUILDING AND CLASSING SUBSEA PIPELINE SYSTEMS .2006 5 Section 3: Rules for Classification CHAPTER 1 Scope and Conditions of Classification SECTION 3 Rules for Classification (1 January 2008) 1 Application These

41、requirements are applicable to those features that are permanent in nature and can be verified by plan review, calculation, physical survey or other appropriate means. Any statement in the Guide regarding other features is to be considered as guidance to the designer, builder, Owner, et al. 3 Risk E

42、valuations for Alternative Arrangements and Novel Features Risk assessment techniques may be used to demonstrate that alternatives and novel features provide acceptable levels of safety in line with current offshore and marine industry practice. The ABS Guide for Risk Evaluations for the Classificat

43、ion of Marine-Related Facilities provides guidance on how to prepare a risk evaluation to demonstrate equivalency or acceptability for a proposed design. Risk evaluations for the justification of alternative arrangements or novel features may be applicable either to the installation as a whole, or t

44、o individual systems, subsystems or components. ABS will consider the application of risk evaluations for alternative arrangements and novel features for subsea pipeline systems. Portions of the subsea pipeline system or any of its components thereof not explicitly included in the risk evaluation su

45、bmitted to ABS are to comply with any applicable part of the ABS Rules and Guides. If any proposed alternative arrangement or novel feature affects any applicable requirements of Flag and Coastal State, it is the responsibility of the Owner to discuss with the applicable authorities the acceptance o

46、f alternatives based on risk evaluations. For new or novel concepts, i.e. applications or processes that have no previous experience in the environment being proposed, the guidance encompassed in the class Rules may not be directly applicable to them. The ABS Guidance Notes on Review and Approval of

47、 Novel Concepts offer ABS clients a methodology for requesting classification of a novel concept. The process described in this guidance document draws upon engineering, testing and risk assessments in order to determine if the concept provides acceptable levels of safety in line with current indust

48、ry practices. 6 ABSGUIDE FOR SURVEYS USING RISK-BASED INSPECTION FOR THE OFFSHORE INDUSTRY .2003 Section 4: Documents to be Submitted CHAPTER 1 Scope and Conditions of Classification SECTION 4 Documents to be Submitted 1 General For classing pipelines according to this Guide, the documentation submi
