So u see cpp been in the industry long before u been in the world. The CPP is ussing for the ships with special manuvering — tugs, fishing bouts or cargo vessels like small RO-RO or container vessels, the FPP is ussing for long voyage vessels — ocean going vessels. Based on my personal experience with a CPP propulsion, where the CPP is engaged or clutched in with the main engine, what happens if there is need to reduce the main engine rpm in an emergency to save the main from an incident of overheating owing to a sudden trip off from the main engine fresh water jacket cooling pump, where the CPP has to be clutched out or disengaged from the main engine before reducing the rpm of the main engine.
I was lucky to have switched on the fresh water jacket cooling pump to reduced and restore to normal the sudden rise in the jacket fresh cooling water having informed the deck officer on watch to reduce speed of CPP to enable disengagement or clutch out of CPP.
CPP has replaced the need for a direct reversible main engine for manoeuvring purpose saving time, saving fuel and cost of maintenance. It is still the best. In my experiences: whilst ship is going astern with rudder in midship position, bow swing to starboard side with FPP; and bow swing to port side with CPP. I have problem with system of pitch controller propler in vibration when i raise the speed the vibration raise and vibrate the whole ship what should i do??? MacElrevey and Daniel H. MacElrevey where, on the page 52, is written that.

Similarly, if you dispense a condiment with particulates from an FP pump, the rounded end of the discharge tube will catch these bits of food and product will not only get back up, but it can spray onto the user.
