Guide for the Classification of Drilling Systems GUIDE FOR THE CLASSIFICATION OF DRILLING SYSTEMS SEPTEMBER 2012 (Updated February 2014 – see next page) American Bureau of Shipping Incorporated by Act of Legislature of the State of New York 1862 Copyright  2012 American Bureau of Shipping ABS Plaza 16855 Northchase Drive Houston, TX 77060 USA Updates February 2014 consolidation includes: • September 2012 version plus Corrigenda/Editorials Foreword Foreword (1 September 2012) This Guide has been revised to assist the industry with Classification of Drilling Systems. This revision supersedes the March 2011 ABS Guide for the Classification of Drilling Systems. This Guide becomes effective as of 1 September 2012. The Guide describes criteria to be used for drilling systems, which are to be approved by the American Bureau of Shipping (ABS), and it is built upon requirements of the recognized codes and standards, as referenced in this Guide. The Guide contains the following nine (9) main sections and five (5) appendices: Section 1 Scope and Condition of Classification Section 2 Design of Drilling Systems Section 3 Drilling Systems Section 4 Scope of Drilling System and Equipment Approval Section 5 Drilling System Piping Section 6 Materials for Drilling Systems and Equipment Section 7 Welding and Nondestructive Examination Section 8 Surveys at Vendor’s Plant During Installation and Commissioning Section 9 Surveys After Construction and Maintenance of Class Appendix 1 Typical Codes and Standards Related to ABS Classification of Drilling Systems Appendix 2 Example of Manufacturer’s Affidavit of Compliance Appendix 3 Example of Independent Review Certificate Appendix 4 Example of Certificate of Conformity Appendix 5 Example of Maintenance Release Note This Guide is to be used in conjunction with other applicable ABS Rules and Guides, codes and standards as referenced therein, and applicable national regulations. ABS Classification continues to provide the offshore industry with a pathway toward agreement by Regulatory Authorities. However, the Owner/Operator’s specific request for compliance with applicable requirements of Flag or Coastal State Authorities affecting the drilling systems is to be filed as an addendum to the Request for Classification. The following changes to the Guide were incorporated into the September 2012 CDS Guide: General • None Section 1 • Editorial changes. • New reference, definitions, and acronyms added. Section 2 • Editorial changes. • Provided “Risk Assessment for Drilling System” • Added submittal requirements for conductor tensioning system/unit. . ABS GUIDE FOR THE CLASSIFICATION OF DRILLING SYSTEMS 2012 iii Section 3 • Revised accumulator hydraulic capacity requirements for subsea and surface BOP stack. • Modified shearing capacity requirements – calculations, testing, etc. • Revised choke and kill systems requirements, and their control system requirements. • Added design requirements for: - Kill Unit - Riser Recoil System - Conductor Tensioning System - Personnel Baskets - Gears and Couplings • Clarifications provided for “Control Systems”. Section 4 • Clarified and modified Table 1 of Section 4. • Provided “Revalidation Date” requirements for IRC. • Allowance of PDAs. • Allowance of limited use of ABS Type Approval Program for selected equipment. Section 5 • Clarified the requirements for “Flexible Lines/Hydraulic Hoses” to consider different service categories. • Clarified the requirements for “Thread Joints and Connections” and “Socket Welds”. • Clarified the requirements for “Fire Resistance”. • Provided requirements for “Primary Product Form”. Section 6 • Revised toughness requirements for structural load-bearing equipment and components. • Provide guidance on structural galvanizing process. Section 7 • Clarified requirements for welding and NDE. • Provided guidance on delayed NDE. • Clarified drawwork testing requirements. Section 8 • Editorial changes. Section 9 • Added requirements for Drilling Equipment Maintenance Plans (DEMP). • Added requirements for prefabrication or kick-off meeting. • Added “Unscheduled Survey” and “Alternatives to Periodic Survey” Appendix 1 • Additional codes and standards. . iv ABS GUIDE FOR THE CLASSIFICATION OF DRILLING SYSTEMS 2012 Appendix 2 • Updated the contents to provide additional parameters for Appendix 2 “Example of Manufacturer’s Affidavit of Compliance” Appendix 3 • Provided “Revalidation Date” for IRC. Appendix 4 • None Appendix 5 • Added example of Survey Report (SR). Appendix 6 • None .
