摘要

莫霍洞是一个穿过地壳的洞,将由一艘钻探船在真正的海洋深处进行钻探。由于在这样的深度下锚是不可行的,钻井船在海底孔上方的位置必须由地面推进装置控制。这个概念被称为“动态定位”。1961年,为了确定动态定位是否可行,在其他工程因素中,进行了一项实验性钻井计划。为四个转向螺旋桨开发了一个特殊的集成控制系统,允许一个操作员控制实验钻井船CUSS i的位置。该系统在海上成功运行了一个月,证明了动态定位不仅可行而且完全实用。预计这一系统将成为控制未来用于地球物理和海洋学研究的水上交通工具的基础。

Dynamic Positioning of the Mohole Experimental Drilling Ship
The drilling of the Mohole, a hole through the crust of the earth, will be undertaken from a drilling ship operating in true oceanic depths. Because anchoring at these depths is infeasible, the position of the drilling ship above the hole in the ocean floor must be controlled by surface propulsion units. This concept is called "dynamic positioning." An experimental drilling program was undertaken in 1961 to determine, among other engineering factors, whether dynamic positioning was feasible. A special integrated control system was developed for four steering propellers which permitted a single operator to control the position of the experimental drilling ship, CUSS I. The system operated successfully for a month at sea and proved that dynamic positioning was not only feasible but entirely practical. This system is expected to form the basis for the control of future waterborne vehicles for geophysical and oceanographic research.
