According to a preferred embodiment of the present invention, the propulsion assisting rotary drum sail system based on the upright tank is characterized by comprising: an upright tank which is fixedly installed in the hull of a ship; and a drum sail which is installed so as to surround a part or all of the outer peripheral surface of the upright tank body, and which has a cylindrical shape having a larger length and diameter than the upright tank body. The rotary cylinder sail is installed in a manner of being concentric with the upright tank body and surrounding the upright tank body in a rotatable manner, and can move along the height direction of the outer peripheral surface of the upright tank body according to specific conditions so as to maintain a certain height. Furthermore, a ship equipped with the propulsion assistance rotary cylinder sail system based on the upright tank body is characterized in that the tank body is upright mounted on the ship body, and the rotary cylinder sail is mounted in a manner of being capable of moving in the vertical direction. According to the present invention, compared with a liquefied natural gas (LNG)-propelled ship, a fuel tank on a hydrogen-propelled ship having a volume of 4 times or more or an ammonia-propelled ship having a space of 2 times or more than that of the liquefied natural gas (LNG) can be more easily mounted. In addition, a rotary drum sail can be simultaneously arranged on the periphery of the tank body to provide assistance for the propulsion power of the ship, so that an additional energy saving effect and a carbon emission reduction effect can be achieved.

    适用本发明之较佳一实施例的基于直立罐体的推进辅助旋筒风帆系统,其特征在于,包括:直立罐体,被固定安装在船舶的船体中;以及,旋筒风帆,采用长度以及直径大于直立罐体的圆筒形态,以围绕直立罐体的外周面一部分或全部的方式进行安装;旋筒风帆以与直立罐体同心并围绕直立罐体的状态以可旋转的方式进行安装,可根据具体状况沿着直立罐体外周面的高度方向进行移动而维持一定高度。此外,基于直立罐体的推进辅助旋筒风帆系统搭载船舶,其特征在于:罐体被直立安装在船体上,旋筒风帆以可在上下方向上进行移动的方式安装。通过如上所述构成的本发明,与液化天然气(LNG)推进船舶相比,可以更加轻易地安装与液化天然气(LNG)相比要求4倍以上的体积的氢气推进船舶或2倍以上的空间的氨气推进船舶上的燃料罐体,而且可以通过在罐体周边同时配置旋转型旋筒风帆而为船舶的推进动力提供辅助,从而达成额外的能源节省效果以及碳排放减少效果。
