PROPELLER NOZZLES

The main advantage of the nozzle is that it increases the thrust on the propeller. Comparing propellers with and without nozzles shows that the nozzle propeller offers about 25% more total thrust (nozzle and propeller) than an open propeller at zero ship speed (bollard condition)

Advantages:
· Give more thrust
· Give more pulling power
· Less fuel consumption
· Give more speed, from the same power input
· Less fuel consumption
· Reduced vibrations
· Safety in ice

Nozzles can be designed and supplied for all types of vessels, but are particularly suited for the following ship types:

· Tugs and pusher tugs
· Fishing vessels
· Research vessels
· Supply vessels and special ships
· Dredger and cable – laying vessels
· Inland – water vessels
· Vessels with full aft – end forms
