Abstract

A mounting arrangement for a propeller device (8), e.g. a transverse propeller, which is disposed in a channel (4) of a vessel's hull (2). The propeller device (8) comprises a tubular casing (10) and a propeller (12), which is rotatably mounted in the casing (10). Between the casing (10) and the channel (4) there is created an annulus (22), wherein there are mounted resilient air containers (30, 32) for elastic, vibration-damping mounting of the casing (10) in the channel (4).At each end of the annulus (22) there is mounted an air container (30,32), which extends round the casing (10) and seals the annulus (22). A compressed air source (50) is connected to the respective air containers (30, 32) via controllable valves (60, 62). Furthermore, a sensor (80) for measuring the channel's (4) vibration and a sensor (20) for measuring the propeller's rotational frequency are provided. By controlling the valves (60, 62) the air containers' (30, 32) spring stiffness can be controlled for minimising the vibration that is transmitted from the casing (10) to the channel (4) during the propeller device's (8) operation.
