LONDON – Lloyd’s Register has launched a new service designed to enhance traditional inspection planning.
Called Risk-based Inspection (RBI), it aims to help achieve higher reliability and a longer operating time; minimizing downtime and reducing risk. The consulting group expects the service to be of interest to operators of floating units at a fixed location, such as FPSO and FLNG vessels.
Tim Walsh, COO of Assurance Services for Lloyd’s Register, said: “RBI techniques may be used to provide justification for the assignment of class, and may be systematically applied to a hull structure and associated components or to individual systems, sub-systems or components.
“The most common deterioration mechanisms associated with hull structure components can range from coating failures, through to fatigue and stress built in to the structure during construction. RBI can help assess all of these issues and prioritize inspection needs.”
Walsh continues: “The key to understanding how classification, verification and integrity fit together is in understanding what differences there are between integrity management and classification schemes. We have investigated this in detail and have launched this new service because these two schemes can be integrated, and the overall result will optimize survey and inspection activities.”
The introduction of an RBI approach aligns the requirements for class, verification, and hull integrity management into a single survey and inspection program.
Rebecca Allison, product development manager, Asset Integrity Services at Lloyd’s Register said: “RBI and class regimes can work in tandem to optimize inspection and maintenance regimes, reduce costs, minimize downtime, mitigate risk and shutdowns.
“However, adopting an RBI approach does require a mind-set change for both Class societies and operators. It is no longer about undertaking surveys at specific times. Rather, they are undertaken based on assessment of risk that each equipment and structural item poses.”
