説明
A prediction method of motion basd on a simulated calculation in the time domain is usually adopted to design and evaluate dynamic positioning capabilities of offshore structures under varying environmental conditions. In this paper, the prediction method of dynamic positioning motion using hydrodynamic forces and moments obtained from captive model tests was proposed. In addition to this, the sea tria1 of the semi-submersible drilling platform was carried out, and from the acquired data, the dynamic response characterstics of motion to the thruster output were calculated. Comparing the results of the sea trial with the predicted results by the present method, the validity of this prediction method was verified. Then, some simulated calculations concerning the dynamic positioning characteristics under combined environmental conditions of current, wind and waves were carried out. It was shown from the power spectra of motion and thruster output that the wave filtering technique was important for reducing the useless operation of thrusters.
