The disclosure provides a pod propulsion system including first and second counter rotating propellers for providing thrust to propel a marine vessel. The pod propulsion system includes a first electric motor (i) for rotating the first propeller and (ii) electrically coupled to a first drive, the first drive being configured to control the first motor and a second electric motor (i) for rotating the second propeller and (ii) electrically coupled to a second drive, the second drive being configured to control the second motor. The first and second drives respectively control the first and second motors interdependently.

Counter rotating propeller pod electrical arrangement

Provided is a pod propulsion system including first and second counter rotating propellers for propelling a marine vessel first and second propeller modules, each including an electric motor having a driving-end configured to rotate the first and second propellers, respectively. Also included are first and second gondolas, each (i) for housing a respective one of the first and second electric motors and (ii) including a boltable interface formed along a lengthwise direction of an extremity of the gondola. A strut (i) connects the first and second gondolas to a hull of the marine vessel (ii) including first and second boltable interfaces. Each of the boltable interfaces of the strut is configured to form a bolted joint interface with a corresponding one of boltable interfaces of the first and second gondolas.

The invention relates to a method for determining the direction and the amplitude of a force applied to a system (IO) comprising a stationary portion () and a mobile portion () which can deform when exposed to said force. Mechanical deformations applied to the mobile portion when exposed to said force are measured by measuring a distance between the stationary portion and the mobile portion in the direction of application of the force, and the distance measurements are processed in order to determine the amplitude and the direction of the force.
