Analyses on helicopter deck under axial and bending

Abstract

Abstract Helicopter deck is one of the structural components on offshore structures. It is very important to transfer especially workman from the land to sea and vice versa. The helideck must be strongly designed for safety not only for human but also for the structure itself. The objective of the present study is to analyze the helicopter deck under axial and bending including the behavior. The nonlinear finite element is adopted to analyze the helicopter deck under axial and bending. The helicopter deck consists of four legs and the plate of the deck is supported by these legs. Three kinds of helicopter, namely Dauphin, Super Puma and EH101 having weight 4.3 ton, 9.3 ton and 14.6 ton, respectively. It is found that the stress on the helicopter deck varies for every load pressure of the helicopter.
