The present invention is directed to a modular azimuth thruster () for propelling a vessel, having a thruster housing () around which water flows, and comprising: a standardized core unit () having a core unit housing () forming part of the thruster housing, a transmission line () arranged within in the core unit housing (), comprising a propeller shaft () extending in a longitudinal direction () of the thruster housing, and a propeller () arranged outside the thruster housing and being operationally connected to the propeller shaft. The present invention further relates to a vessel comprising an azimuth thruster and a method of configuring an azimuth thruster.

Modular azimuth thruster

Propulsion unit () for propulsion and maneuvering of a maritime vessel, which includes a nozzle () exhibiting a curved following edge () at outlet of the nozzle (), which results in that length of the nozzle () is longer in upper part of the nozzle () and shortest at the outermost points of a horizontal central axis through the nozzle (), when the nozzle () is seen from behind.
