一条 S-lay 起重机驳船,命名 CNOOC 201,为管子在华南海在深海的油 / 气体地里放被造了。它由于在一年 2010 底被委托。一个特殊上升系统被开发遇见从一条 S-lay 驳船安装深海的起床人是困难的并且没被完成的挑战。这份报纸的目的是在如此的一个创新系统上调查模型测试,它不得不在域申请前被做。由使用类似理论, S-lay 驳船的运动通过六个 degrees-of-freedom 运动平台被模仿,并且一个截断的模型起床人为测试的模型被利用。在起床人的截断的位置的排水量和力量边界条件从链状的管理方程被获得并且变得由一辆滑道大车和设计控制模型起床人的配置的一个装载系统认识到,它介绍一种类似的配置给一个真正的起床人在深海。测试结果在对理论计算的很好的同意,证明活跃截断的测试为控制在测试调查的模型的深海的起床人的配置是适用的。
An S-lay crane barge,named CNOOC 201,has been built for pipe laying in deepwater oil/gas fields in the South China Sea.It is due to be commissioned by the end of the year 2010.A special lifting system is developed to meet the challenge that installing deepwater risers from an S-lay barge is difficult and has not been achieved.The purpose of this paper was to investigate the model test on such an innovative system,which has to be done before field application.By applying the similarity theory,the movement of the S-lay barge is simulated through a six degrees-of-freedom motion platform,and a truncated model riser is utilized for the model testing.The displacement and force boundary conditions at the truncated position of the riser are obtained from the catenary governing equation and become realized by a slideway cart and a loading system designed to control the configuration of the model riser,which presents a similar configuration to a real riser in deepwater.The test results are in very good agreement with theoretical calculations,showing that the active truncated test is applicable for controlling the configuration of the deepwater riser in model testing investigation.
