Various aspects provide for a propulsion system () for a ship () comprising at least first and second thrusters () and first and second directors (), wherein a computing platform () is coupled to the thrusters and directors being configured to receive desired longitudinal and lateral headings () and determine a configuration of the propulsion system that is expected to propel the ship in the desired longitudinal and lateral headings.

Navigation system with independent control of lateral and longitudinal thrust

The invention relates to a system and method for cooling of a pod propulsion device, including a motor casing () and a strut (), which strut () is connected at a lower part thereof to the motor casing () and is arranged to be connected at an upper part thereof to a hull () of a ship, said motor casing () including a housing () enclosing an electric motor () with a stator () and a rotor, wherein periodically a forced cooling air flow (W,S) is shifted to use a front duct (A) as supply (S) for limited time period TF and thereafter shift to use the aft duct (B) 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.
