PROBLEM TO BE SOLVED: To provide a marine propulsion system capable of effectively reducing fuel consumption of a main engine of a marine vessel during waiting for a long time on the water.SOLUTION: The marine propulsion system comprises the propulsion commanding unit operated between a neutral state and propulsion state, a main engine driving a thruster, a clutch lying between the thruster and the main engine, and switched between a connecting state and cut-off state, a motor driving the thruster and a control device controlling the main engine, clutch and motor. The control device stops the main engine as well as switches the clutch to the cut-off state after the propulsion commanding unit is operated from the propulsion state to the neutral state, and then, the control device starts the motor and drives the thruster when the propulsion commanding unit is operated from the neutral state to the propulsion state.SELECTED DRAWING: Figure 1
【課題】水上で待機する時間が長い船舶において、主機の燃料消費量を効果的に低く抑えることができる舶用推進システムを提供する。【解決手段】舶用推進システムは、中立状態と推進状態との間で操作される推進指令部と、推進機を駆動する主機と、推進機と前記主機の間に介在する、連結状態と遮断状態との間で切り換えられるクラッチと、推進機を駆動する電動機と、主機、クラッチおよび電動機を制御する制御装置と、を備え、制御装置は、推進指令部が推進状態から中立状態に操作された後にクラッチを遮断状態に切り換えるとともに主機を停止し、その後に推進指令部が中立状態から推進状態に操作されたときに電動機を起動して推進機を駆動する。【選択図】図1
