动力定位（DynamicPositioning，DP）是一种通过控制船上的推力器产生推力向量来对风、浪和流等外部的作用力进行补偿，以使水面船舶的位置自动地保持在给定范围内的技术。

Dynamic Positioning ( DP ) is a technique of automatically maintaining the position and heading of the floating vessel within the specified limits by controlling onboard thrusters which generate thrust vectors to counter the wind , wave and current forces .

船舶各位置的缆力分布系数与对应该位置的缆绳相对长度λL有关，缆绳相对长度λL越小，对应的缆力分布系数越大。

The mooring line forces distributing coefficient of various positions in a ship is connected with the comparative length λ _f to a certain location . The λ _f is smaller and the corresponding coefficient is bigger .

通过精确的推进命令自动控制船舶的位置和航向是动力定位系统的主要功能。

The major function of DP system is to automatically control of a vessel 's position and heading via precise thruster commands .
