Notices and General Information

Introduction

1. The year 2008 edition of the Rules for Building and Classing Steel Vessels is a complete reprint of the 2007 edition, consisting of the eleven (11) booklets as shown in Table 1. In this regard, we would bring the following to the users attention:

a) The purpose of the generic title ABS Rules for Conditions of Classification (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 vessels, barges and specific shipboard arrangements/systems, etc., except for those in offshore service, as specified in the Foreword to Part 1.

b) The purpose of the generic title ABS Rules for Materials and Welding (Part 2) 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.

c) The purpose of the generic title ABS Rules for Survey After Construction (Part 7) is to reflect the expanded contents of PART 7, as a result of including consolidated requirements for Surveys After Construction applicable to all types and sizes of vessels, barges and specific shipboard arrangements/systems, etc., as specified in Part 7, Chapter 1, Section 1.

2. The numbering system applied in the Rules is shown in Table 2.

3. The primary changes from the 2007 edition of the Rules are identified and listed in Table 3. The effective date of the indicated Rule Changes is 1 January 2008, 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 Steel Vessels 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 Steel Vessels, 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 http://www.eagle.org/absdownloads/index.cfm for download.

7. In association with the introduction of the Common Structural Rules for Double Hull Oil Tankers and Bulk Carriers, respectively, on 1 April 2006, Part 5 of the Rules for Building and Classing Steel Vessels was divided into three Sub-parts, 5A, 5B and 5C. The contents and application of each Part are as follows:
