Guide for Building and Classing Floating Production Installations GUIDE FOR BUI

Guide for Building and Classing Floating Production Installations GUIDE FOR BUILDING AND CLASSING FLOATING PRODUCTION INSTALLATIONS JULY 2009 (Updated July 2012 – see next page) American Bureau of Shipping Incorporated by Act of Legislature of the State of New York 1862 Copyright  2009 American Bureau of Shipping ABS Plaza 16855 Northchase Drive Houston, TX 77060 USA ii ABS GUIDE FOR BUILDING AND CLASSING FLOATING PRODUCTION INSTALLATIONS . 2009 Updates July 2012 consolidation includes: • November 2010 version plus Notice No. 1 and Corrigneda/Editorials November 2010 consolidation includes: • April 2010 version plus Corrigneda/Editorials April 2010 consolidation includes: • November 2009 version plus Corrigneda/Editorials November 2009 consolidation includes: • July 2009 version plus Corrigneda/Editorials ABS GUIDE FOR BUILDING AND CLASSING FLOATING PRODUCTION INSTALLATIONS . 2009 iii Foreword F o r e w o r d Foreword This Guide specifies 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 this Guide 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, tension 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. This Guide is to be used in conjunction with other ABS Rules and Guides, as specified herein. The effective date of this Guide is 1 July 2009. In general, until 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. The 2009 edition of the Guide for Building and Classing Floating Production Installations is a reorganization of the September 2007 edition of the FPI Guide with modifications and updates for ship-type Floating Production Installations. The 2009 edition consists of the seven (7) Parts as shown in Table 1 below. In general these seven Parts subdivide the Guide into parts that are more consistent with other ABS Rules. The primary modifications are described in the following: a) PART 5A “Ship-Type Installations” reflects changes in the requirements for both new builds and conversions to FPI. There are changes to the loading conditions, strength and fatigue assessment procedures and hull interface structure analysis procedures. Conversions to FPI also require finite element analysis of the converted hull structure. b) PART 5B “Other Installation Types” which address Column-Stabilized units, Tension-Leg Platforms and Spars essentially remains unchanged from the 2007 edition. The primary changes from the September 2007 edition of the Guide are for Ship-Type Conversions to Floating Production Installations as identified and listed below. • Analysis and Design of Other Major Hull Structural Features (Section 5A-1-4). • Steel Renewal Assessment (Section 5A-2-2) • Fatigue Consideration (Remaining Fatigue Life) (Section 5A-2-3). • Finite Element Analysis (5A-1-3/3.3, 3.5, 3.7 and Appendix 5A-3-A4). • Loading patterns in 5A-3-2/Figures 1A to 1D. • Buckling Strength of Longitudinal Strength Members (Appendix 5A-2-A1). • Hull Girder Ultimate Strength (5A-3-3/3.5 and Appendix 5A-3-A3). • Fatigue Assessment – Loading Conditions (5A-3-A2/7.5). • Fatigue Assessment of Structures Considering Low Cycle Fatigue (5A-3-A2/15). • Column-Stabilized Installations (Sections 5B-1-1 and 5B-1-2). • Wave Impact Criteria (Appendix 5B-A1). • Hull Surveys (Part 7, Chapter 2). iv ABS GUIDE FOR BUILDING AND CLASSING FLOATING PRODUCTION INSTALLATIONS . 2009 TABLE 1 Applicable Editions of Booklets Comprising the 2009 Guide Part 1: Conditions of Classification (Supplement to the ABS Rules for Condition of Classification – Offshore Units and Structures) 2009 Part 2: Materials and Welding 2009 Part 3: Installation Types, Functions, Features and General Requirements 2009 Part 4: Units Systems (Process and Import/Export) 2009 Part 5A: Ship-Type Installations 2009 Part 5B: Other Installation Types 2009 Part 6: Mooring Systems 2009 Part 7: Surveys After Construction 2009 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, installations, 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 Classification” more readily a common Rule of the various ABS Rules and Guides, as appropriate. Thus, Part 1, Chapter 1 of this Guide specifies only the unique requirements applicable to floating production installations. These supplemental requirements are always to be used with the aforementioned Rules for Conditions of Classification – Offshore Units and Structures (Part 1).
