Description

This paper shows that the new CODAD solusion using 4 engines and 2 propellers is interesting for a 2500 tons frigate, thanks to a new generation of diesel engines with low compression ratio and two stages turbo charging process (SEMTPielstick PA6BTC engines) and that the frigates up to 4500 tons and even 5000 tons can be built in the same way with the following advantages, that is, noise detection improved thanks to the elastic mounting of complete propulsion units, infrared detection improved, compact and independent propulsion units, very good survivability, narrow inlet and exhaust ducting, large flexibility of operation and large overhaul interval and easy maintenance on board by crew, etc..
