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.
