Fluid Structure Interaction Analysis of Abnormal Wave Slamming Events
Rolland, Louise Ankerstjerne (Master thesis, 2018)In critical sea states, slamming wave loads may cause severe structural damage to marine structures. The slamming loads are associated with fluid-structure impacts with high pressures and short durations. The structural ... -
The Motion of Slender, Cylindrical Bodies - An Experimental and Theoretical Investigation
Birkeland, Frid Grøtterud (Master thesis, 2018)An accidentally dropped object in the sea can result in critical damage on pipelines, platform base structures and underwater installations. This has to be accounted for during offshore operations and installations. Earlier ...
