scope:

This Guide is specifically targeted for structures and topside process systems for the offshore oil and gas industry. This Guide specifically covers:

i) Static pressure retaining equipment, and

ii) Structures for offshore floating installations, including hull structure, mooring system and production riser systems.

Items specifically excluded from the scope of this Guide are Instrumentation and Control (I&C) systems, electrical systems and non-static machinery components. For non-static machinery components, the ABS Guide for Surveys Based on Machinery Reliability and Maintenance Techniques provides guidance for a risk-based approach relevant to such types of equipment.

For existing offshore floating installations with an ABS approved RBI plan or ISIP (updated with an RBI plan), appropriate notations are to be issued upon the completion of the next Annual Program Health Check as per 5/9.7 or the next 5-Year Program Health Check as per 5/9.9 and the RBI program found to be maintained satisfactorily.

It is noted that while this Guide is primarily intended for offshore floating installations, the general methodology and related steps can be adapted for application to marine vessels and fixed-based platforms. In order to enroll in an RBI program for such assets, the Owner/Operator is requested to contact the responsible ABS Survey Office.
