RR246 - Effect of platform robustness on inspection planning

Offshore platforms require inspection of the underwater portion of the structure on a regular basis. A "robust" structure has inherent redundancies in terms of alternative load paths around any damaged areas and adequately proportioned alternative member strength that allow it to withstand global damage caused by ship impact, fatigue cracking, extreme storms, dropped objects, and other events. Therefore, robust structures may not need as much inspection as other structures, since they are less vulnerable to damage.
