Design Optimization & Lightweighting: Considering Uncertainties for Marine Applications

Reducing weight through design optimization can be another way to deal with global warming since it could reduce greenhouse gas emission. However, uncertainty can have a decisive effect on reliability and safety of a structure when the design is near-optimal or optimal. In this presentation, we will introduce how to consider uncertainties from environmental (wave, wind, current) loads, material properties, and manufacturing process in marine applications using RAMDO to obtain a reliable and light weighted design.
