Title:
TORSIONAL VIBRATION STRESS REDUCTION CONTROL DEVICE, MARINE VESSEL COMPRISING SAME, AND TORSIONAL VIBRATION STRESS REDUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2013/088643
Kind Code:
A1
Abstract:
A torsional vibration stress reduction control device (50) according to the present invention is used to reduce torsional vibration stress occurring in a propulsion shafting (10) in a marine vessel (100) comprising a propulsion shafting (10) which rotates integrally with a propulsion propeller (11), a main engine (20) for driving the propulsion shafting (10), and a supercharger (30) which has a turbine (31) driven by exhaust (27) expelled from the main engine (20) and which uses the rotational force of the turbine (31) as motive power to compress new air and supply scavenged air (24) to the main engine (20), wherein the pressure of the scavenged air (24) is reduced when the torsional vibration stress is a predetermined value or greater.
