2、5 Northchase Drive Houston, TX 77060 USA Foreword Foreword Foreword These Rules specify the ABS requirements for building and classing Floating Production Installations (FPIs) that should be used by designers, builders, Owners and Operators in the offshore industry. The requirements contained in the

3、se Rules are for design, construction, and survey after construction of the floating installation (including hull structure, equipment and marine machinery), the position mooring system and the hydrocarbon production facilities. Floating installations of the ship-type, column-stabilized-type, tensio

4、n leg platforms and spar installations are included, as well as existing vessels converted to FPIs. The requirements for optional notations for disconnectable floating installations, dynamic positioning systems and import/export systems are also provided. These Rules are to be used in conjunction wi

5、th other ABS Rules and Guides, as specified herein. The effective date of these Rules is 1 January 2017. In general, until the effective date, plan approval for designs will follow prior practice unless review under these Rules is specifically requested by the party signatory to the application for

6、classification. Changes to Conditions of Classification (1 January 2008) For the 2008 edition, Part 1, 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, in

7、stallations, vessels or systems in offshore service. The purpose of this consolidation was to emphasize the common applicability of the classification requirements in “Part 1, Chapter 1” to ABS-classed offshore units, pipelines, risers, and other offshore structures, and thereby make “Conditions of

8、Classification” more readily a common Rule of the various ABS Rules and Guides, as appropriate. Thus, Part 1, Chapter 1 of these Rules specifies only the unique requirements applicable to floating production installations. These supplemental requirements are always to be used with the aforementioned

17、troduction 1. The 2017 edition of the Rules for Building and Classing Floating Production Installations consists of the seven (7) Parts as shown in Table 1. In general these seven Parts subdivide these Rules into parts that are more consistent with other ABS Rules. With regard to two Parts, Part 1,

18、and Part 2: a) The purpose of the generic title ABS Rules for Conditions of Classification Offshore Units and Structures (Part 1) is to reflect the expanded contents of PART 1, as a result of including consolidated requirements for “Classification” applicable to all types of and sizes of units, inst

19、allations, vessels or systems in offshore service, etc., as specified in the Foreword to Part 1. Additional specific requirements are contained in Part 1 of these Rules for Building and Classing Floating Production Installations. b) The purpose of the generic title ABS Rules for Materials and Weldin

20、g of PART 2 is to emphasize the common applicability of the requirements to ABS-classed vessels, other marine structures and their associated machinery, and thereby make PART 2 more readily a common “PART” of various ABS Rules and Guides, as appropriate. 2. The numbering system applied in the Rules

21、is shown in Table 2. 3. The primary changes from the 2016 Rules are identified and listed in Table 3. The effective date of the indicated Rule Changes is 1 January 2017, unless specifically indicated otherwise. 4. The effective date of each technical change since 1993 is shown in parenthesis at the

22、end of the subsection/paragraph titles within the text of each Part. Unless a particular date and month are shown, the years in parentheses refer to the following effective dates: (2000) and after 1 January 2000 (and subsequent years) (1996) 9 May 1996 (1999) 12 May 1999 (1995) 15 May 1995 (1998) 13

23、 May 1998 (1994) 9 May 1994 (1997) 19 May 1997 (1993) 11 May 1993 For certain changes that have a major impact on shipyards, designers and vendors, ABS has instituted a two-year Rule cycle to give the industry more time to prepare for these changes. The text of these changes will appear in a box alo

24、ng with the effective date just under the existing Rule requirement. 5. Until the next edition of the Rules for Building and Classing Floating Production Installations is published, Notices and/or Corrigenda, as necessary, will be published on the ABS website www. eagle.org only, and will be availab

36、11 if the minimum design fatigue life specified is 30 years. If in addition, spectral fatigue analysis (see 1-1-2/5.11) is requested by the owner or designer, only the design fatigue life notation, SFA(number of years),Year will be assigned and published in the Record for the hull and hull interface

37、 structural system. Although only the SFA notation is assigned, and not the FL notation for ship-type installations, the required fatigue analysis of Appendix 5A-3-A2 is to be performed and the calculated fatigue life is to satisfy the design fatigue life. The (number of years) refers to the design

38、fatigue life equal to 20 years or more (in 5-year increments), as specified by the applicant. Where different design fatigue life values are specified for different structural elements within the installation, such as hull structure components, hull interface structures and position mooring system c

39、omponents, the (number of years) refers to the least of the target values. In the case when spectral fatigue analysis is also applied the least of the fatigue life values calculated by the required fatigue strength analysis for the FL notation and the spectral fatigue analysis must satisfy the desig

40、n fatigue life. The “design fatigue life” refers to the target value set by the applicant, not the value calculated in the analysis. For example if the design fatigue life is specified as 25 years, the fatigue calculations of hull structural components must satisfy a fatigue life of 25 years. The fa

41、tigue calculations of the position mooring hull interface structures and hull mounted equipment interface structures, and position mooring system must also satisfy fatigue lives of (25 FDF) years, where FDF are the fatigue safety factors specified in 5A-1-4/Table 1, 5B-1-2/Table 2, 5B-2-3/Table 2 or

42、 5B-3-3/Table 2, as applicable, for hull interface structures and in 6-1-1/Table 1 for mooring lines.

43、bols, and Notations 1-1-2 5.11.3 Conversion of Existing Vessel to FPSO, FPS or FSO (2016) When an existing vessel is converted to an FPSO, FPS or FSO in the process referred to as an FPI vessel conversion, and the ship-shaped FPSO, FPS or FSO is classed under the provisions of Section 5A-2-1, the ex

44、pected minimum remaining fatigue life of the structure is to be assessed according to Section 5A-2-3 and documented by recording its value in the Record. The RFL notation will be followed by the value of the expected minimum remaining fatigue life in years, and the year of maturation of fatigue life

45、 in the defined site location in accordance with 1-1-2/5.9.2. For example, RFL(15), 2018 indicates that the expected minimum remaining fatigue life of the structure is 15 years, which will be reached in the year 2018. The RFL(number of years), Year notation as applied to an FPI vessel conversion is

46、mandatory. When an existing vessel is converted to a FPSO, FPS or FSO and is intended to be used at marginal field and the unit will be drydocking every 5 years, the RFL notation may be omitted. A notation MARGINAL FIELD (site) will be added after CI to indicate the intended use for 5 years for the

47、site. For a marginal field FPI without RFL notation, the following actions will be required: Verification of the existing vessels original fatigue life. If the remaining fatigue life as unrestricted vessel is not less than 5 years and Alpha factors for the intended site is greater than 1, the fatigu

48、e analysis for the hull structure is not mandatory. However, the hull interface structures for process modules, flare tower, mooring structure, riser porch or balcony are to be evaluated for compliance with 5A-1-4/3, based on FEM models and including fatigue analysis. The analysis is to apply the mo

49、st critical combination of topsides or mooring loads and hull girder loads. If the remaining fatigue life as unrestricted vessel is less than 5 years, or if the Alpha factors for the intended site is not greater than 1, the fatigue analysis for the hull is mandatory for a fatigue life of 10 years. The fatigue analysis of the hull structure is to comply with 5A-2-1/5.7. The hull interface structures for process modules, flare tower, mooring structure, riser porch or balcony are to be evaluated for compliance with 5A-1-4/3, based on FEM models and i
