Ice Forces on Conical Structures due to Change in Water Level

Abstract

In cold regions, changes in water level can induce vertical forces on offshore structures when sea ice cover interact with the structures.A rise in water level generates an upward force on a downward- breaking conical structure;likewise, a drop generates a downward force on a upward- breaking conical structure.These forces are induced on conical structures even if sea ice cover to structure adfreeze bonding is not present.The authors have proposed a method of calculation that estimates the vertical ice forces on conical structures taking the bending failure of the ice cover.
