Installation of propeller equipment into the ship hull can be done in many different ways as both yards and owners have different requirements of how to install and how to run the propeller equipment. Other designs of stern tube and/or shaft sealing may be preferred. MAN B&W Alpha are available with alternatives to meet specific wishes or design requirements.
