摘要:

为解决钻井平台避台作业时悬挂隔水管的安全性问题,针对现用的软悬挂与硬悬挂技术各自的局限性并结合二者优势,提出一种设有动载主动补偿功能的新型柔性隔水管悬挂系统方案。在传统的硬悬挂装置的基础上设置运动补偿液压缸和增程系统,利用有限补偿行程最大程度降低隔水管动载;提出位移比例补偿法和加速度削峰法两种补偿方案,并开展了适应性对比研究;建立Simulink仿真模型,进行系统仿真分析。计算分析表明,提出的隔水管柔性悬挂系统方案具有良好的动载补偿功能,其中加速度削峰法优于位移比例补偿法。

Abstract:

To solve the safety problem of riser during operation while avoiding typhoon on a drilling platform, the paper proposes a system scheme for the new-type flexible hang-off of the riser equipped with active compensation function in view of limitations and advantages of the current soft hang-off and hard hang-off technologies. Based on using the traditional hard hang-off device, a hydraulic cylinder with motion compensation and a stroke increasing system are set up to minimize the dynamic load of riser using the limited compensation stroke. Further, this paper proposes two compensation schemes, i.e., displacement compensation in proportion and acceleration peak clipping method, then carries out a comparative research on their applicability. and establishes the Simulink simulation model to perform a system simulation analysis. The computational analysis shows that the proposed system scheme of flexible hang-off for riser has good dynamic loading compensation function, and the acceleration peak clipping method is superior to the displacement compensation in proportion.

Key words: riser, avoiding typhoon, flexible hang-off, dynamic loading compensation, control strategy
