ABS RULES FOR BUILDING AND CLASSING MOBILE OFFSHORE DRILLING UNITS . 2012 1

Notices and General Information

Introduction 1. The year 2012 edition of the Rules for Building and Classing Mobile Offshore Drilling Units

consists of the nine (9) booklets as shown in Table 1. The Rules have been reorganized, and a new Part 6 for equipment and machinery certification has been added. The survey requirements in the former Part 6 are now in Part 7, along with requirements for surveys during construction and for testing and trials. The cross-reference table in Table 4 shows the relationship between the 2008 numbering and the 2012 numbering. 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 offshore units, pipelines, risers, and other offshore structures, as specified in the Foreword to Part 1.

With regard to Part 2, the purpose of the generic title ABS Rules for Materials and Welding 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 is shown in Table 2.

3. The primary changes from the 2008 edition of the Rules are identified and listed in Table 3. The effective date of the indicated Rule Changes is 1 January 2012, unless specifically indicated otherwise.

4. The effective date of each technical change since 1993 is shown in parenthesis at the 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 May 1998 (1994) 9 May 1994 (1997) 19 May 1997 (1993) 11 May 1993

5. Until the next edition of the Rules for Building and Classing Mobile Offshore Drilling Units is published, Rule Change Notices and/or Corrigenda, as necessary, will be published on the ABS website – www. eagle.org – only, and will be available free for downloading. It is not intended to publish hard copies of future Rule Change Notices and/or Corrigenda to existing Rules or Guides. The consolidated edition of the Rules for Building and Classing Mobile Offshore Drilling Units, which includes Rule Change Notices and/or Corrigenda using different colors for easy recognition will be published on the ABS website only when RCN and/or Corrigenda are issued.

6. The listing of CLASSIFICATION SYMBOLS AND NOTATIONS is available from the ABS website www.eagle.org for download.
