Introduction

The 2024 edition of the Rules for Building and Classing Offshore Installations consists of the Parts as shown in Table 1. In this regard, we would bring the following to the user’s attention:

a) The purpose of the generic title ABS Rules for Conditions of Classification – Offshore Units and Structures (Part 1B) is to reflect the expanded contents of PART 1B, as a result of including consolidated requirements for “Classification” applicable to all types of and sizes of units, installations, vessels or systems in offshore service, etc., as specified in the Foreword to Part 1B. Additional specific requirements are contained in Part 1 of these Rules for Building and Classing Offshore Installations.

b) The purpose of the generic booklet ABS Rules for Alternative Arrangements, Novel Concepts and New Technologies (Part 1D) is to introduce a procedure for acceptance of alternative arrangements, novel concepts, and new technologies based on Goals and Functional Requirements, including a consolidated list of Tier 1 Goals.

c) The purpose of the generic title ABS Rules for Materials and Welding 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.

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

The primary changes from the January 2023 Rules are identified and listed in Table 3. The effective date of the indicated Rule Changes is 1 January 2024, unless specifically indicated otherwise.

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.

For certain changes that have a major impact on shipyards, designers and vendors, ABS has instituted a two-year Rule cycle to give the industry more time to prepare for these changes. The text of these changes will appear in a box along with the effective date just under the existing Rule requirement.
