  • Hydraulic steering arrangement for a thruster of a marine vessel
    Patent number: 9969479
    Abstract: A novel design of a hydraulic steering arrangement for a thruster of a marine vessel is specifically designed for thrusters intended to operate in an arctic environment where ice is present. To meet the arctic demands the steering arrangement is provided with a cross-over safety block arranged close to the hydraulic steering motor for absorbing the torque subjected to the thruster by ice for instance.

  • Thruster assembly in a marine vessel
    Patent number: 9849938
    Abstract: An assembly in a marine vessel includes a unit arranged in a water tight chamber opening in a hull of a vessel, wherein the unit is adapted to extend into the water below the vessel when at a mounted position. A connection path between an inside and an outside of the vessel is provided with a sealing system and the sealing system divides the connection path into an outside connection path portion and an inside connection path portion. The assembly includes a gas inlet system opening to the outside connection path portion.

  • Pitch angle indicator system
    Patent number: 9796461
    Abstract: A pitch angle indicator system indicates a pitch angle of blades of a propeller of a marine propulsion unit. A mechanical link couples at least one of the blades to a first end of a first rod. An indicator is coupled to a second end of the first rod. The mechanical link is configured to convert a change in the pitch angle into a rotation of the first rod about its longitudinal axis. The indicator is configured to provide an indication of the amount of rotation of the first rod about the longitudinal axis.

  • Method of and an arrangement for improving the lubrication system of a propulsion device of a marine vessel
    Patent number: 9758229
    Abstract: A method of and an arrangement for improving the lubrication system of a propulsion device of a marine vessel are specifically applicable in removing water from the lubrication oil of various types of thrusters. An inert gas is arranged from an inert gas source to flow through a gas cavity in the lubrication system for flushing moist gas from the cavity.

  • Method of arranging the lubrication of a steerable thruster of a marine vessel and a lubrication arrangement therefor
    Patent number: 9630693
    Abstract: The lubrication of a steerable thruster of a marine vessel is based on splash-type lubrication at the pod and full bath lubrication in the stembox and in the shank. The lubrication oil enters the pod both from the stembox and the shank via a constriction and directly from the oil tank. The oil is further circulated from the pod to the oil tank by means of pumps.
