摘要: 顶端张紧立管广泛用于深水海洋平台之中, 所处海洋环境非常复杂而容易产生疲劳损伤, 因此动力 响应研究非常重要。在 A B AQU S中建立了张力腿平台顶端张紧立管模型, 水深设为15 0 0m、 海域为南中国海。采 用海洋工程模块 AQUA进行了波浪和海流加载, 获得了沿立管轴向的不同位置节点的应力时间曲线。数值计算表 明, 由于海平面附近的立管受到波浪和海流的作用, 最大应力出现在海平面下4m处, 该位置为最危险点。

Abstract: Top tensioned risers are widely used in deepwater platforms, and are easily to be damaged for complex marine environmental loads, so dynamic responses of which should be researched carefully. A model was established using ABAQUS [JP2]to describe top tensioned risers of tension leg platforms located in China south sea, and water depth of the model was set as [JP] 1 500 m. Marine engineering model AQUA was applied to add wave and current effects on riser, and to output stress time curves at different positions along the riser. Results of calculation demonstrate that because of strong wave and current effect, the location with the largest fatigue damage rate of the riser is 4 m below sea level.
