PROBLEM TO BE SOLVED: To provide a hybrid propulsion device for vessel capable of being automatically switched to an operation mode capable of reducing exhaust gas in a restricted sea area.SOLUTION: A hybrid propulsion device for vessel includes: a diesel engine generator 2 driven by a diesel engine 1, for supplying power to an AC bus line; a main converter 3 for supplying power to a DC bus line by converting voltage of the AC bus line to DC; a main converter 4 for driving an AC motor 5 by converting the voltage of the DC bus line to AC; a propeller 7 connected to the AC motor 5; a fuel cell 41 supplying power to the DC bus line; an inverter 22 for converting power from the DC bus line to the AC bus line; an inboard load 31 connected to the AC bus line; a power adjustment device 80 for monitoring and adjusting inboard; and position information acquirement means 90. The power adjustment device 80 is driven in a mode taking care of inboard power with the diesel engine 2 while the vessel is sailing on high seas and in a mode taking care of inboard power with the fuel cell 41 when position information of the position information acquirement means 90 crosses a waste gas restriction position set beforehand.SELECTED DRAWING: Figure 1

    【課題】規制海域において、排気ガスを低減可能な運転モードに自動的に切り替えられる船舶用ハイブリッド推進装置を提供する。【解決手段】ディーゼルエンジン1で駆動され、交流母線に給電するディーゼル発電機2と、交流母線の電圧を直流に変換して直流母線に給電する主コンバータ3と、直流母線の電圧を交流に変換して交流電動機5を駆動する主インバータ4と、交流電動機5に接続されたプロペラ7と、直流母線に給電する燃料電池41と、直流母線から交流母線へ電力変換するインバータ22と、交流母線に接続された船内負荷31と、船内の電力を監視・調整するための電力調整装置80と、位置情報取得手段90とで構成する。電力調整装置80は、船舶が公海を航行中は、ディーゼル発電機2で船内電力を賄うモードで運転し、位置情報取得手段90の位置情報が予め設定された排ガス規制位置を横切ったとき、燃料電池41で船内電力を賄うモードで運転する。【選択図】図1
