The present invention relates to a method for controlling rotation speed of a self-contained winch for an LNG marine vessel for providing rotation power to a lifter winding a rope or a chain. The method for controlling rotation speed of a self-contained winch for an LNG marine vessel for providing rotation power to a lifter winding a rope or a chain comprises: a step of determining a mode for determining whether or not a mode is an automatic operation mode or a manual operation mode; a step of comparing a temperature for comparing a hydraulic oil temperature and a set temperature; a step of comparing a pressure for comparing a pressure inside a distribution block and a set pressure; a step of comparing a speed for comparing a rotation speed of a winch detected by an encoder and a set speed; and a step of comparing a load for comparing a load applied to a power transferring shaft detected by a pressure sensor and a set load, thereby capable of maintaining a constant rotation speed by the power transferring shaft when the pressure detected by the pressure sensor is not equal to the set pressure, or the rotation speed detected by the encoder is not equal to the set speed.
