...DYNAMIC AND RISK-BASED INSPECTION PROGRAMS FOR OFFSHORE STRUCTURES BASED ON STRUCTURAL DIGITAL TWIN Giovanni Buizza Avanzini, Francois-Xavier Sireta, DNV This paper was presented at the 17th OMC Med Energy Conference and Exhibition in Ravenna - Italy, 08-10 April 2025. It was selected...

... to analyze the problem. Empirical and integral models provide a good representation of the phenomena but they are based on simplifications, moreover they are not able to model the sea surface behavior, crucial since is the zone where interactions with offshore structures, vessels and floating installations...

... solution for offshore structures are discussed, and a case study on the use of the monitoring solution for a highway bridge in Germany is exposed. The two inspection and monitoring solutions enable asset owners to reduce operational downtime, improve maintenance planning and asset integrity...

... a seismic point of view. A review of main seismic codes for offshore structures, typical design approaches and requirements for the seismic design basis are then discussed. Finally, some key aspects and case histories from our experience are reported to draw attention to some specific issues related...

... to periodic underwater inspections but no significant failures were detected. In order to eliminate unnecessary tests a new approach has been followed based on the recent monitored environment data and the reliability re-assessment analysis of the offshore structures in operating conditions. The target...

... ABSTRACT: This paper proposes an optimum arrangement method of Al galvanic anodes for a cathodic protection on offshore structures when environmental factors on the cathodic protection are parametrically changed. In order to propose an optimum arrangement method of Al galvanic anodes...
