topside structure

Calculated by the model, distortion and stress distribution of the platform topside structure are obtained, the dangerous parts of the structure are definite.

计算得到了平台上体结构变形分布及应力分布，明确了结构的危险部位。

Piping design for offshore platform topside facilities Features of the Jacket and Topside Structure

海洋平台生产设施配管设计导管架和平台上部结构的特点

The Technology of Jacket Platform Launch Features of the Jacket and Topside Structure

导管架下水技术导管架和平台上部结构的特点

Finally, the relation curves between load and synchronous precision are got. The reference method to control the synchronous accuracy of topside structure lifting system is provided.

最终，得出载荷大小以及偏载程度与同步精度之间的关系曲线，为控制上部组块提升系统的同步精度提供参考方法。

The paper comes from one sub-subject of the major projects of national science and technology. Topside structure lifting system is researched.
