6、Guide for Building and Classing Offshore LNG Terminals. The GBLNGT Guide also describes criteria to be used for gravity based offshore LNG terminals which are to be classed or certified by American Bureau of Shipping (ABS). ABS is willing to expand the criteria for handling other gaseous materials f

7、or gravity based terminals as the industry demand for same increases. ABS recognizes that industry participation is a vital factor due to the rapidly progressing use of offshore gas terminals. To understand and apply this new technology and its standards, ABS, the offshore and onshore community, and

8、 regulatory agencies would benefit from having a common understanding of the terms and concepts involved, and an awareness of how these concepts are to be applied to ABS rule-making. This continues to be the driving force for the Guide. The effective date of this Guide is 1 June 2010. In general, un

9、til the effective date, plan approval for designs will follow prior practice unless review under this Guide is specifically requested by the party signatory to the application for classification. Changes to Conditions of Classification Chapter 1, Section 1, “Scope and Conditions of Classification” w

10、as 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 offshore service. The purpose of this consolidation was to emphasize the common applicability of the classification requi

11、rements in “Chapter 1, Section 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 various ABS Rules and Guides, as appropriate. Thus, Chapter 1, Section 1 of this Guide specifies only t

12、he unique requirements applicable to gravity-based offshore liquefied gas terminals. These supplemental requirements are always to be used with the aforementioned Rules for Conditions of Classification Offshore Units and Structures (Part 1). Reference Note Reference to a paragraph in the Steel Vesse

13、l Rules, MODU Rules or FPI Rules is made in the format P-C-S/ss.p where P is the Part, C is the Chapter, S is the Section, ss is the Subsection and p is the Paragraph. Reference to a paragraph in this Guide is made in the format C-S/ss.p, where C is the Chapter, S is the Section, ss is the Subsectio

20、itions of Classification (Supplement to the ABS Rules for Conditions of Classification Offshore Units and Structures) 1 Classification The requirements for conditions of classification are contained in the separate, generic ABS Rules for Conditions of Classification Offshore Units and Structures (Pa

21、rt 1). Additional requirements specific to gravity-based offshore LNG terminals are contained in the following Subsections. 3 Purpose A Gravity-Based Offshore LNG Terminal provides LNG storage and receives and/or offloads LNG. There are two major variations of offshore LNG terminal: Load Terminals a

22、nd Discharge Terminals, with various configurations of each. A Load Terminal receives gas directly from one or more wells or from another offshore facility where it may or may not have been processed. The gas is liquefied in an onboard liquefaction facility and stored for offloading as LNG to a trad

23、ing LNG carrier. Alternatively, a Load Terminal may receive LNG from a liquefaction plant via a pipeline. A Discharge Terminal receives LNG from trading LNG carriers and stores it. In such terminals, the stored LNG is normally vaporized in a re-gasification facility and discharged ashore. However, o

24、ffloading LNG in a lightering operation is also feasible. 5 Classification Symbols and Notations A listing of Classification Symbols 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” i

25、s available from the ABS website “http:/www.eagle.org”. The following notations are specific to gravity-based offshore LNG terminals. 5.1 Class Notations Gravity-based offshore LNG terminals that have been built, installed and commissioned to the satisfaction of the ABS Surveyors to the full require

26、ments of this Guide, where approved by the Committee for service for the specified design environmental conditions, may be classed and distinguished in the ABS Record by the symbol null A1, followed by Offshore Liquefied Gas Terminal and the appropriate notation for the intended service listed below

27、. 2 ABSGUIDE FOR BUILDING AND CLASSING GRAVITY-BASED OFFSHORE LNG TERMINALS .2010 Chapter 1 Conditions of Classification Section 1 Scope and Conditions of Classification 1-1 Class notations were chosen to provide a clear description of the function of each configuration using the following symbols:

28、G Gravity Based L Liquefaction Facility O Transfer of LNG (Offloading/Loading) P Gas Processing Facility R Re-Gasification Facility S Storage Facility T Terminal with processing facilities that are not classed A complete description of applicable class notations is provided for gravity-based offshor

29、e LNG terminals in 2-1/1.1 of this Guide. 5.3 Geographical Limitations Gravity-based offshore LNG terminals which have been built to the satisfaction of the ABS Surveyors to special modified requirements for a limited service, where approved by the Committee for that particular service, may be class

30、ed and distinguished in the Record by suitable symbols or notations, but the symbols or notations will either be followed by or have included in them the appropriate service limitation. 5.5 Terminals Not Built Under Survey The symbol “null” (Maltese-Cross) signifies that the system was built, instal

31、led and commissioned to the satisfaction of the ABS Surveyors. Gravity-based offshore LNG terminals and their equipment that have not been built under ABS survey, but which are submitted for Classification, will be subjected to special consideration. Where found satisfactory and thereafter approved

32、by the Committee, they may be classed and distinguished in the Record by the notation described above, but the symbol “null” signifying survey during construction will be omitted. 7 Rules for Classification 7.1 Application of Rules This Guide contains provisions for the classification of gravity-bas

33、ed offshore LNG terminals. This Guide is intended for use in conjunction with the ABS Rules for Building and Classing Steel Vessels (Steel Vessel Rules), ABS Rules for Building and Classing Mobile Offshore Drilling Units (MODU Rules), ABS Rules for Building and Classing Offshore Installations, ABS R

34、ules for Building and Classing Floating Production Installations (FPI Rules) or other applicable ABS Rules and Guides. 7.3 Scope of Class A description of the parts of a gravity-based offshore LNG terminal included in the ABS classification is provided in 2-1/1 of this Guide. 7.5 Alternatives Any de

35、parture from the requirements of this Guide may be considered by ABS on the basis of an additional risk assessment to that required per 2-2/3 of this Guide, or at least a separate, clearly identified part of the risk assessment. In the case of such departures, classification is subject to ABSs appro

36、val upon a demonstration of fitness for purpose in line with the principles of ABS Guides and Rules, as well as recognized and generally accepted good engineering practice. Risk acceptance criteria are to be developed in line with the principles of the ABS Rules and are subject to ABSs approval. The

37、 ABS Guidance Notes on Risk Assessment Application for the Marine and Offshore Oil and Gas Industries contain an overview of risk assessment techniques and additional information.

38、ection 1 Scope and Conditions of Classification 1-1 A risk approach justification of alternatives may be applicable either to the terminal as a whole or to individual systems, subsystems or components. As appropriate, account must be given to remote hazards outside of the bounds of the system under

39、consideration. Such account must include incidents relating to remote hazards directly affecting or being influenced by the system under consideration. ABS will consider the application of risk-based techniques in the design of the terminal, verification surveys during construction and surveys for m

40、aintenance of class. Portions of the terminal not included in the risk assessment are to comply with the applicable parts of the ABS Rules. The following are the responsibility of the Owner/Operator: i) Risk acceptance criteria ii) Hazard identification iii) Risk assessment iv) Risk management v) Co
