Abstract Objectives / Scope We set out with a clear objective of mitigating the inherent risk of Confined Space Entry (CSE) and working at height - particularly on floating production systems in Cargo Tanks (Oil & Gas). The safety risks have been quantified in human and economic terms in a recent Cambridge University Report, which the paper will draw on and demonstrate risk reduction and lives saved. Joint industry projects, in particular HITS (hull inspection techniques and strategies), whose members included the major class societies and supermajors, have encouraged and guided developments in technology which have enabled measurable risk reduction. Methods, Procedures, Process Building on that collaboration, market feedback has directed and supported technology development much of which has now been used in Malaysian waters. This has specifically enabled development in robotics, advanced inspection and monitoring methods, including, laser deflection as a rapid method for assessing structural strength, and Artificial Intelligence (AI) to assess corrosion severity. The physics behind the laser deflection system measures deflections of the tank plating under known load conditions using a robotic laser scanning system. The measured deflections are compared against the predicted Finite Element Analysis (FEA) deflections and design FEA parameters to confirm structural condition of the whole tank structure. The laser scans also measure corrosion extent and condition amongst other critical integrity data. We will also present progress made with methods that inspect through-wall bottom plating using subsea robots and advanced Non-destructive Testing (NDT) that can see ‘through’ marine growth and tank residues, thus minimising the risks and cost of tank internal cleaning. Class and industry encouragement and collaboration has been vital in the success, introduction and continued progress of these developments which mitigate safety risk, improve productivity, enhance data fidelity, and help assure integrity. Results, Observations, Conclusions Class has endorsed the results achieved thus far giving owners and operators the necessary regulatory assurance of the benefit of proceeding both in procedural and technical terms. Early outcomes demonstrate a reduced impact on operations; fewer Persons on Board (POB), shorter time to achieve results leading to regulatory approval, less preparation time, less cleaning, and therefore improving cost effectiveness. Those results can also demonstrate that lives have been saved. Novel / Additive Information The paper will demonstrate progress of an evolutionary approach through disruptive technological innovation to change conventional thinking, while improving safety, structural integrity, and operational efficiency.
