  • Navigation system with independent control of lateral and longitudinal thrust
    Patent number: 11526169
    Abstract: Various aspects provide for a propulsion system (200) for a ship (100) comprising at least first and second thrusters (205, 206) and first and second directors (220, 720), wherein a computing platform (300) is coupled to the thrusters and directors being configured to receive desired longitudinal and lateral headings (750, 760) and determine a configuration of the propulsion system that is expected to propel the ship in the desired longitudinal and lateral headings.
    Type: Grant

  • Pod propulsion device and a method for cooling such
    Patent number: 9902478
    Abstract: The invention relates to a system and method for cooling of a pod propulsion device, including a motor casing (3) and a strut (2), which strut (2) is connected at a lower part thereof to the motor casing (3) and is arranged to be connected at an upper part thereof to a hull (1) of a ship, said motor casing (3) including a housing (6) enclosing an electric motor (5) with a stator (51) and a rotor, wherein periodically a forced cooling air flow (W,S) is shifted to use a front duct (2A) as supply (S) for limited time period TF and thereafter shift to use the aft duct (2B) as supply (S) for a limited time period TA. The invention also relates to a ship provided with such a system and method for cooling of pod propulsion device.
