The invention discloses a ventilation mast sail device of an LNG ship. The ventilation mast sail device comprises a ventilation mast, a ventilation mast cover cylinder, a cylindrical sail, a bearing, a hub motor assembly, a motor sail connecting piece, a hub motor supporting piece, a cover cylinder supporting piece and a cover cylinder fixing piece. A ventilation mast cover cylinder is installed on the ventilation mast, the cylindrical sail is connected with the hub motor assembly through a motor sail connecting piece, the cylindrical sail is installed on the ventilation mast cover cylinder, and the invention further relates to an LNG transport ship used for the LNG ship ventilation mast sail. The LNG ship ventilation mast and the cylindrical sail are combined together, the space for arranging the cylindrical sail is saved, meanwhile, the cylindrical sail is used for providing auxiliary power for the LNG ship, sailing oil consumption is reduced, the effects of energy conservation and emission reduction are achieved, and the shipping cost is reduced.
本发明公开了一种LNG船透气桅风帆装置,该装置包括透气桅、透气桅罩筒、圆筒风帆、轴承、轮毂电机组件、电机风帆连接件、轮毂电机支撑件、罩筒支撑件和罩筒固定件;所述透气桅上安装透气桅罩筒,所述圆筒风帆和轮毂电机组件通过电机风帆连接件连接,所述圆筒风帆安装在透气桅罩筒上,还涉及到一种用于LNG船透气桅风帆的LNG运输船舶。本发明通过将LNG船透气桅和圆筒风帆结合在一起,既节省了布置圆筒风帆的空间,同时利用圆筒风帆为LNG船提供辅助动力,降低航行油耗,达到节能减排的效果,降低了航运成本。
