ABSTRACT:
A vessel comprises a cylindrical hull (10) containing a structure (11) carrying machinery (M) supported from the hull (10) by electromagnetic levitation means (12-17) that maintain electromagnetic forces between flux gaps (24) which are arranged to extend radially of the adjacent hull (10) curvature and longitudinally of the hull (10). In this manner, the transmission of noise from the machinery (M) to the hull (10) is obviated so as to reduce the detectable acoustic signal emitted by the vessel and furthermore, radial expansion or contraction of the hull (10) is prevented from mechanical transmission to the structure (11) via the levitation means (12-17).
