For Offshore and subsea Assets; the importance of SIM gets even more due to the high costs of Inspection, Maintenance and Repair (IMR) activities.

The objective of this paper is to introduce to the Oil & Gas stake holders in the offshore market a deep understanding of SIM methodology and the procedures of establishing SIM system for their assets according to the API RP 2SIM practices which is considered one of the state-of-art practices to manage fixed offshore platforms integrity.

The paper objective is achieved by representing a true project case applying practices and procedures of API RP 2SIM for a 120 Platform fleet using Qualitative (Risk Based) approach describing the basis of platforms data gathering, categorization, ranking and selection for assessment, setting inspection strategy & planning.

It is concluded from this paper that SIM system is an enabler of the success of AIM system, and qualitative approach is considered a reliable and economic method for dealing with SIM projects, wall thickness measurements has a key role in the integrity of offshore platforms, software has a key role in SIM system sustainability and finally acceptance criteria is one of key issues that needs to be addressed in SIM projects. Added to that a set of recommendations is proposed to API RP 2SIM that might be useful to be considered next version.

This paper shares with our stake holders in the oil & gas market a valuable experience of constructing a SIM system for operators using a real life project case, introduce comprehensive application of recommended practices and finally deepen the awareness of importance of SIM systems for sustainable development of offshore oil & gas assets.
