ABS RULES FOR BUILDING AND CLASSING STEEL VESSELS.2011 1


Introduction

1. The year 2011 edition of theRules for Building and Classing Steel Vessels is a complete reprint ofthe 2010 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 ABSRules for Conditions of Classification (Part 1) is toreflect the expanded contents of PART 1, as a result of including consolidated requirementsfor Classification applicable to all types of and sizes of vessels, barges and specificshipboard 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 2is 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 requirementsfor 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 2010 edition of the Rules are identified and listed in Table 3. Theeffective date of the indicated Rule Changes is 1 January 2011, unless specifically indicated otherwise.

4. The effective date of each technical change since 1993 is shown in parenthesis at the end of thesubsection/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, RuleChange 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 hardcopies of future Rule Change Notices and/or Corrigenda to existing Rules or Guides. Theconsolidated edition of the Rules for Building and Classing Steel Vessels, which includes RuleChange Notices and/or Corrigenda using different colors for easy recognition, will be published

on the ABS website only when Rule Change Notices and/or Corrigenda are issued.

6. The listing of CLASSIFICATION SYMBOLS AND NOTATIONS is available from the ABSwebsite http://www.eagle.org/absdownloads/index.cfm for download.

7. In association with the introduction of the Common Structural Rules for Double Hull Oil Tankersand Bulk Carriers, respectively, on 1 April 2006, Part 5 of the Rules for Building and ClassingSteel Vessels was divided into three Sub-parts, 5A, 5B and 5C.

For oil tankers with structural arrangements not covered by Part 5A, the requirements inPart 5C, Chapters 1 or 2, are to be complied with.

Application Bulk Carriers

The structural requirements in Part 5B of the Rules are applicable for single side skin and

double side skin bulk carriers of 90m in length and upward, with structural arrangementsas specified in Part 5B, Chapter 1, Section 1.

For vessels intended to carry ore or bulk cargoes, other than the single side skin or double

side skin bulk carriers of 90 m in length and upward with structural arrangements asspecified in Part 5B, Chapter 1, Section 1, the requirements in Part 5C Chapters 3 or 4 are

to be complied with.

Application ABS Construction Monitoring Program

These compulsory requirements forCSR notation are specified in Part 5C, Appendix 2.
