Abstract

A real time motion of moored FPSO in side-by-side configuration for regular wave is simulated in ANSYS AQWA to evaluate the structure motion responses and cable forces under criteria and operational wave conditions for two sea-state. The mooring failure is simulated wherein whole cable tensile forces are calculated. Downtime occurs when the vessel motion and cable responses in operating wave conditions exceed the safe limiting values. With the help of a real time wave scatter diagram of three different locations in Malaysian waters, the probability occurrences are obtained and finally a novel study on the downtime cost analysis for offloading operations is performed considering structure responses and mooring failure conditions. In this paper, a successful attempt has been made to connect vessel motion responses to cost. This paper evaluates the possible downtime cost and economical risks involved in the different locations of Malaysian waters for offloading operations.

考虑船舶运动和系泊响应的马来西亚水域卸载作业停机成本分析

在ANSYS AQWA软件中，模拟了FPSO在规则波浪条件下的实时运动，以评估两种海况下的标准和工作波浪条件下的结构运动响应和索力。模拟了锚泊破坏过程，计算了锚索整体拉力。当船舶运动和电缆在工作波条件下的响应超过安全极限值时，就会发生停机。借助马来西亚水域三个不同位置的实时波散点图，获得了发生概率，最后进行了考虑结构响应和系泊失效条件的卸载作业停机成本分析的新研究。本文成功地将船舶运动响应与成本联系起来。本文评估了马来西亚水域不同位置卸载作业可能涉及的停机成本和经济风险。
