    Abstract: A pitch angle indicator system indicates a pitch angle of blades (201) of a propeller of a marine propulsion unit. A mechanical link (202) couples at least one of said blades (201) to a first end of a first rod (211). An indicator (216) is coupled to a second end of said first rod (211). The mechanical link (202) is configured to convert a change in said pitch angle into a rotation of said first rod (211) about its longitudinal axis (204). Said indicator (216) is configured to provide an indication of the amount of rotation of said first rod (211) about said longitudinal axis (204).

    Abstract: A slewing seal arrangement (1) for a steerable thruster of a marine vessel which comprises a slewing seal assembly (2) comprising a set of at least two annular seals (3) arranged around the vertical shank (4) of the steerable thruster. The slewing seal assembly further comprises above said set of annular seals an upwardly elongated section housing a spare set of annular seals arranged around the vertical shank and a mechanism for locking and releasing the slewing seal assembly for allowing the seal assembly to be moved and for allowing the spare set of annular sets to be taken into use.

    Abstract: In a method for maintenance of a ship propeller while the propeller is under water, the following steps occur: placing a flexible habitat (3) having an open upper end over an uppermost blade (1) and a portion of the propeller hub such that the habitat covers a part of the blade and at least a maintenance portion, and establishing a gas seal (31) between the upper end of the habitat and the blade to close the habitat at its upper end. After fixing the lower end of the habitat relatively to the propeller such that the lower end of the habitat remains below the maintenance portion, compressed gas is introduced into the habitat to displace the water in the habitat, so that maintenance work can be carried out at the maintenance portion above water level inside the habitat. The apparatus for maintenance of a ship propeller under water comprises a flexible habitat with an open upper end. The habitat has a gas seal adapted to cooperate with a propeller blade surface to establish a gas seal to close the habitat at its upper end and fixing means adapted to fix the open lower end of the habitat relatively to the propeller. A means for introducing compressed gas into the habitat is provided to displace the water in the habitat.
