An electric propulsion ship with Tandem typed POD propulsors was investigated in view of the propulsive performance and the ship maneuverability.(1) Based on SENSHO which is the first inland vessel with electric propulsion system in Japan, a new ship with Tandem typed POD propulsors was designed and its model was manufactured.(2) Using the model, resistance and self-propulsive tests were carried out in Towing Tank, Hiroshima University. As a results, we found that the propulsive performance was improved about 2-3% by changing the Tandem typed POD propulsors.(3) Center skegs of the hull have to be shortening for the ship with Tandem typed POD propulsors. Due to the effect, we found that the course-keeping ability was reduced in comparison with original SENSHO in the tank test.(4) To settle this problem, a new Tandem typed ship with twin side skegs was proposed. We confirmed that the new type ship is promising.

从推进性能和船舶操纵性两个方面对串联式POD推进船进行了研究。(1)以日本第一艘采用电力推进系统的内河船舶SENSHO为基础，设计并制作了串联式POD推进器的船舶模型。(2)利用该模型在广岛大学拖曳水池进行了阻力和自航试验。结果表明，采用串联式POD推进器后，推进性能提高了约2-3%。(3)对于串联式POD推进器，船体中心尾骨必须缩短。针对这一问题，提出了一种新型的双侧尾骨串列式船舶。我们确认这艘新型船很有前途。
