导管架拖航疲劳分析

Fatigue Analysis on Jacket Transportation

由于传统工程设计对于拖航疲劳的考虑不能反映导管架的实际受力状态,不能合理考虑拖航期间驳船遭遇的海况,详述导管架拖航疲劳分析的流程和基本原理,结合工程实例分析拖航疲劳的影响,并对拖航疲劳设计和海上拖航作业给出建议。

Due to the fact that the consideration of towing fatigue in traditional engineer- ing design can not reflect the actual stress state of the jacket, and can not reasonably consider the sea condition encountered by the barge during towing, the flow and basic principle of the towing fatigue analysis of the jacket are described in detail, and the effect of the towing fa- tigue is analyzed with an example of the project. Some suggestions are given for the towing fa- tigue design and the towing operation at sea.
