I am relatively new to Ship technology and require your professional advice for my doubt on machine room layout for DE propulsion.
The following sketch (from a Wärtsilä brochure) depicts a layout in which the prime mover (W12C46C @ 12.6 MW) and associated alternator are separated by a watertight bulkhead :
IOW, this means that the prime mover and associated alternator are physically located in separate compartments.
I’m wondering how common such a configuration might be, and what would be its plus / minuses vs a more conventional layout where prime mover + alternator are physically located in the same compartement.
Thanks in advance.
