Application
The application of the Rules and Guides is, in general, based on the contract date for construction between the shipbuilder and the prospective Owner. (e.g., Rules which became effective on 1 July 2004 are not applicable to an offshore unit or structure for which the contract for construction was signed on 30 June 2004.) See also 1-1-4/3.
The requirements in these Rules are the common requirements for conditions of classification of offshore units and structures.
Any unique requirements for a specific type of offshore unit or structure are specified in the supplement to these Rules in each of the following Chapters.
These Rules are to be used together with the applicable supplemental Rules for the specific type of unit or structure.
Asbestos Free Declaration
In the July 2023 edition, in Chapter 1 (Scope and Conditions of Classification), under Section 7 (Plans and Design Data to be Submitted), this part was added:
The party requesting ABS review or approval of plans declares and warrants that all materials used for the structure, machinery, piping, electrical installations and equipment are asbestos free in accordance with SOLAS and IACS interpretations.
ABS reserves the right to perform unscheduled surveys of the hull, equipment, or machinery when ABS has reasonable cause to believe that the Rule requirements for periodical, damage and other surveys are not being complied with.
