Description: Current industrial practice for the inspection of topsides
structures is based on API-RP-2SIM requirement that
inspection of topsides structure be performed annually by
visual examination. However, the final report of the Joint
Industry Project (JIP) on the Structural Integrity Management
(SIM) of topsides structures acknowledged that even if the
annual visual inspection allows a high proportion of typical
degradations to be detected, it may fail in detecting those
that lead to a significant percentage of the reported failures
(MSL, 2004). It proposed therefore a risk-based approach as
an alternative to improve topsides inspection regimes. This
leads to more frequent and detailed inspection of high-risk
structures increasing the likelihood of detecting early
enough critical defect.
Following the release of the API-RP-2SIM which addresses
the issue of Risk-Based Inspection (RBI) especially for the
underwater structure of fixed offshore platforms, the development
of guidance for the RBI of other offshore structures,
especially topsides structures is being considered. In this
vein, the International Organization for Standardization
(ISO) has developed a specific standard for the SIM of offshore
structures (ISO/DIS 19901-9) including topsides structures
in which guidance for performing RBI is provided.
