The new hydrographic surver ship “SHOYO” with capacity of 3, 200tons, is now under construction in the Japan Maritime Safety Agency as a replacement of the old ship “SHOYO” which was constructed in 1972. This new ship is expected to be completed in March, 1998. The electric propulsion system was first employed in the Japan Meritime Safety Agency. It is equipped with diesel engine generators as a power source for every application on sailing. The electric propulsion system is provided with 2 sets of 2, 800kW main-generators to drive the fixed pitch propellers at a motor output and speed of 2, 100kW/262-290rpm ahead. The thyristor motor system is applied to driving 2 sets (2 shafts of propellers.) In addition, one set of bow-thruster (800kW) is located at the stem for controling the ship with the Joy-stick conbined to the electric propulsion system during fixed point observation.
