Abstract

Efficient and accurate estimation of mat-like VLFS's hydroelastic responses in waves is very important for the design. Within the category of simplified methods, the beam on elastic foundation (BOEF) model seems to be the simplest. In this paper, a comparative study is carried out to four BOEF models.They are denoted as S Y BOEF,T_BOEF,S_BOEF and A_BOEF models respectively. It is found that the S Y BOEF model proposed by Suzuki and Yoshida[11,12] are too conservative to be used but the other three BOEF models are able to predict the hydroelastic responses of VLFS in head seas reasonably.The A_BOEF model extended from S_BOEF model[20] by present authors [21] is regarded to be the best both in terms of consistency and accuracy.The BOEF model is very simple and efficient for calculation and is readily applied for practical design.
