Oil or water lubrication Custom design and manufacturing
Blades and propeller hub made of NiBrAl

MMS Design

Masson-Marine offer two types of CPP design, see below MMS design:

MMS (Masson-Marine Separated): the servo cylinder controlling the blade angle is located on the propeller shaft, inboard. The advantage of this system is that maintenance operations do not require the dry-docking of the ship.

Please have a look at the sketche for better understanding.

  • Features
  • Options
  • 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.
  • 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.
