本文对浅水导管架水平度问题进行分析,通过制定调平程序,结合实际工况,把导管架的水平度调整到规范范围之内,并且分析了造成导管架水平度出现问题的主要原因以及规避方式.

本文对海上风机发电的安装方式进行分析研究,通过分析计算,在基于船舶等资源不足等情况下,通过优化设计,安装简易钢结构平台来解决履带吊吊高不足的问题,本方法安全可靠,节约成本,可以广泛应用于海上风机的安装工作.

通过GRLWEAP打桩软件对钢桩打桩过程进行分析,计算连续打桩、短期停锤、长期停锤3个工况锤击数,分析钢桩打桩过程拒锤情况,并应用理论计算的方法组合钢桩打桩动应力以及自由站立静应力进行钢桩强度校核.综合2种计算结果,选择打桩锤型号,依据所选打桩锤计算钢桩自由站立,以满足打桩要求.

According to the API specification,the use of SACS software is modeling structure and calculating the reaction force of each leg when the module is transporting process. The stress,strain and displacement result are obtained by using ANSYS software analyzing the ship. By ana-lyzing the results,determine the position of barge which is easily damaged. On the basis of the module loadout and transport barge strength re-quirements put forward more scientific recommendations,provide the basis for how to reduce the structure loading,transport barge stress.

相较与渤海,东海海域水深较深,风、浪、流等环境极为恶略,且涉猎该海域的施工项目较少,为结构物在该海域的海上吊装施工提出了更高的要求,尤其是风险极高的海上套井口吊装工艺.本文通过在东海海域的施工案例分析,初步探讨该施工工艺的科学、合理海上吊装的方案,为今后同类工程实践提供参考.

SACS software was applied to build the finite element model of the structure,static analysis of structures in accordance with the API[1] specification,calculating the reaction force of each leg when the module is loadout process. By two loadout form:checked respectively by ANSYS software,using the calculation were compared and choose suitable form. In the actual project,the paper puts forward reasonable suggestions on the strength when the large structure loadouts on ship,in order to provide the basis for reducing the stress of the structure.

使用SACS软件对导管架坐底稳定性进行了分析,考虑了环境荷载和插桩对导管架的影响,通过校核防沉板设计的安全性与可靠性,避免了不合理的插桩顺序带来的作业风险,为导管架海上施工提供了技术保障.
