Numerical Research on Elasto-Plastic Response of FPSO Topside Modules Subjected to Blast Loading Aiming at a Simplified Design Method

Structural blast analysis is usually done with two load levels for different design stages; the Strength Level Blast, SLB, and the Ductility Level Blast, DLB. Strength Level Blast is the lower magnitude overpressure (with a higher frequency of occurrence and lower consequence) and Ductility Level Blast is the higher magnitude overpressure (with...

Blast analysis of offshore topside structures: Predicting plastic effects in linear calculations

One of the most dangerous events that can occur on an offshore topside structure is an explosion. If blast analyses is performed without taking plasticity into account, then it may lead to very conservative design. On the other hand monitoring the weight by optimising the structural design is an important design aspect of such structures....
