Abstract
In order to evaluate the seakeeping performance at sea and the safety of mooring on berthing, it is necessary that the ship dynamic motion induced wave and wind should be measured in real time domain for the validity of theoretical evaluation method such as seakeeping performance and safety of mooring.

The seakeeping performance can be evaluated by measuring only hull vertical acceleration of a ship.

The seakeeping performance can be defined as the ability of a ship to go to sea, and to accomplish its missions successfully and safely even in adverse environmental conditions.

In this paper, the basic design of sensors is discussed and the system configurations were shown. The developed system consists of 4 kinds of sensors, i.e. three dimensional accelerometer, two dimensional tilt sensor, two displacement sensors and azimuth sensor.

Using this Hull Motion Measuring System(HMMS), it can be obtained the 6 degrees of freedom of ship dynamic motions at sea and on berthing such as rolling, pitching, yawing, swaying, heaving and surging under the certain external forces.

The Hull Motion Measuring System is useful to evaluate the seakeeping performance and the safety of mooring of a ship. The results are applied to develop the optimum ship route system and next generation voyage data recorder.
