What provisions are generally made to reduce the noise and vibration emanating from the propulsion machinery installation, especially on passenger ships?
A
The propulsion machinery is resiliently mounted to machinery beds integral to the doublebottom structure, and power is transmitted without use of flexible couplings.
B
The propulsion machinery is rigidly bolted to machinery beds integral to the double-bottom structure, and power is transmitted with use of flexible couplings.
C
The propulsion machinery is rigidly bolted to machinery beds integral to the double-bottom structure, and power is transmitted without use of flexible couplings.
