Features
- MMI propellers have a system allowing to spot hydraulic leaks if a problem should arise. It enables us to determine whether the oil leak can be fixed from inside or from the outside of the ship.
- Each propeller system is determined individually for your ship, and a specific comprehensive installation drawing is made.
- The optimal blade profile is computed and drawn for each project individually.
- Propeller hub and blades are made of NiBrAl
- Emergency system for come-home operation after a major hydraulic or electric breakdown.
Options
- The stern tube can be lubricated either by water or oil.
- The OD-box (oil distribution box) can be fitted to the gearbox or set up separately.
- The propeller shaft can be supplied in C 45 grade steel or 316 L stainless steel.
- High skew blade open water propeller for significantly reduced cavitation.
- Adding a nozzle will increase propeller thrust by approximately 20 %.
- Our propellers receive approval by all survey and classification organisations.
