液压驱动转盘在海洋固定平台模块钻机上的设计与应用

海洋固定平台模块钻机空间狭小、布局紧凑、要求设备具有尺寸小、质轻、集成度高、运行安全可靠等特点,而传统电机驱动转盘的驱动方式存在传动链长、传动部件多、传动装置复杂、结构尺寸庞大等问题,在模块钻机尺寸有特殊要求的情况下安装难度大、使用和维修不便,影响总体布局和结构形式的设计。针对上述情况,通过液压驱动转盘与电驱动转盘进行对比,总结出液压驱动转盘小巧轻便、易于建造安装、能够优化钻台结构、操作维护费用低、安全可靠等特点,可为空间有特殊要求的海洋固定平台模块钻机提供一定的参考。

Design and application of hydraulic drive rotary table of modular drilling rig on offshore ifxed platform

Owing to small space and compact layout, the modular drilling rig on the offshore ifxed platform has to meet the requirement of small scale, light weight, high integration, operational safety and reliability. However, there are several problems for the traditional motor-driven pattern, such as long transmission chain, many transmission parts, complex transmission devices, large structural dimensions and heave weight, etc. As a result, it is diffcult to be installed and is inconvenient for usage and repair under special requirements, which affects the design of overall layout and structural conifguration. In view of the above situation, it compares the hydraulic drive rotary table with the electrical drive rotary table. It is concluded that the hydraulic drive rotary table can be characterized of small footprint, light weight, easy installation and construction, capability of structural optimization, low cost of operational maintenance, and great safety and reliability. It can provide certain reference for the modular drilling rig with the special space requirements on the offshore ifxed platform.
