Abstract

Exploration areas of maritime resources such as oil and natural gas have gradually moved to deep sea areas. It became difficult to use existing fixed marine structures which has high cost of build because that are reached to economic uppermost limit. Therefore floating marine structures and flexible marine structures are preferred. Particularly, slender Bodies such as risers and pipes are important part of ocean depth marine structures. slender Bodies are having more and more flexible structures characteristics when they go deep water area overall length becomes longer also slenderness ratio of diameter / length gets grow relatively. In addition, dynamic behavior of slender Bodies is getting complicated because external forces such as tide and wave are given directly. In this study, in order to compensate for these problems, we use to study flexible slender Bodies of different modulus of elasticity. As a result, we compiled statistics and compared behavior of flexible slender Bodies of different modulus of elasticity. In future we expect It would be reference data for design of structure.
