PURPOSE:To estimate a tidal current direction and a flowvelocity without using a special tidal current meter, by estimating the tidal curent direction and the flow velocity by utilizing an automatic ship position holding device. CONSTITUTION:A processing device calculated a direction of a tidal current and a flow velocity from bow and stern direction force FX and ship's side direction force FY obtained from an automatic ship position holding device DSP, an output of a moment Mphi, and an output of a fluid force data storage device of a ship. |
