A new approach referred as “the network modeling method” was developed by the authors to analyze the behaviors of marine structures. In this paper the method is briefly described and applied to predict the loads acting on the connectors between the two modules of the Scientific Research and Demonstration Platform (SRDP), which was deployed in a complicated wave environment near islands and reefs in South China Sea. Based on this method, the response amplitude operators (RAOs) of the connector loads of the SRDP in regular waves, and the time variations of the connector loads of the SRDP in an on-site measured random sea state are predicted and presented. The significant stresses at 20 spots of the local connection structure induced by the connector loads in the sea state are further calculated. The comparisons between the predicted and the on-site measured stresses confirm that the network modeling method is feasible to some extent and especially useful for design of the connectors’ arrangement, estimation of the connector loads and the related structural safety of a multi-module floating structure in early design stage.

网络建模方法在科研示范平台中的应用-连接器负载分析
作者开发了一种称为“网络建模方法”的新方法来分析海洋结构的行为。本文简要介绍了该方法,并将其应用于预测科学研究和示范平台(SRDP)两个模块之间的连接器上的载荷,该平台部署在南海岛屿和礁石附近的复杂波浪环境中。基于此方法,预测并给出了SRDP连接器载荷在规则波中的响应幅度算子(RAO),以及在现场实测随机海况下SRDP连接器载荷的时间变化。进一步计算了海况下连接器载荷在局部连接结构的20个点处引起的显着应力。
