摘要
目前海洋平台日趋集成化、模块化,重量和体积都逐渐增大,使得适合安装大型组块的浮托安装法得到飞速发展。介绍荔湾3-1大型导管架平台浮托安装中使用的实测技术,对驳船的运动监测和海洋环境监测等测量数据进行分析,分析结果被应用于指导整个浮托安装过程,保证浮托安装符合安全施工标准。对浮托安装载荷转移阶段采用数值计算方法进行作业过程模拟,将计算结果与实测结果进行对比分析,两者具有较好的相似性。
Offshore platforms become increasingly integrated and modular with large weight and size. Floatover installation method which is more suitable for the installation of large topsides develops rapidly. This paper presents the field measurement techniques used in the floatover installation of the Liwan 3-1 mega topsides. The motion measurements of barge and the environmental field measurements,etc.,were conducted to guide the entire floatover operation. The field measurement data ensured the floatover operation to be performed as rapidly as possible and coincident with safe practice. Numerical method is used to simulate the mating operation process,and the calculated results are compared with field measurement showing that they have the same pattern of changes.
