Abstract
The engine and other machinery within a marine vessel is mounted on a raft which is relatively flimsy compared with conventional constructions. The raft is supported by electromagnets, the current to which is controlled so as to avoid vibration and flexing which would otherwise take place and so as to reduce transmission of vibration to the hull and other parts of the ship.
Claims7
A mounting for machinery, comprising:
- a flexible raft for mounting items of machinery;
- electromagnetic means, including an array of electromagnets disposed for supporting, in operation, said raft and the items of machinery mounted on said raft;
- sensing means, including an array of sensing elements, arranged for sensing dynamic properties of said raft at different places on said raft;
- and
- control means connected to said electromagnetic means and to said sensing means controlling said array of electromagnets in dependence of signals received from said sensing means so that the electromagnets in said array of electromagnets support said raft for maintaining the items of machinery mounted on said raft in a substantially fixed positional relationship to one another.
