Structural Integrity Monitoring (SIM) is a growing practice, offering alternatives to periodic inspection, that can remove uncertainties and allow service work to continue without interruption. As computing power has increased, the abilities of SIM systems have similarly changed. Demands of the local environment and structural design have also resulted in changes to the capabilities of SIM. Changes in technology are examined with specific examples of enhancements particularly in monitoring of offshore structures. A UK-based organisation aiming to harmonise SIM methods to improve safety by removing common errors and reduce SIM development costs is also discussed.
