Abstract (en)

The retractable thruster comprises a cylindrical first housing (21) extending in a first direction downwards from a bottom of a hull (10) of a vessel and a second housing (22) being attached to a lower end (21A) of the first housing (21). A first shaft (31) extends in the first direction within the first housing (21) and a second shaft (41) extends in a second direction within the second housing (22). The two shafts (31, 41) are connected with a transmission (34, 44). A propeller (50, 51) is attached to an outer end (41 B) of the second shaft (41). A lifting arrangement (80, 81, 82, 83) is arranged within the vessel for lifting and lowering the first housing (21). A first electric motor (60) positioned within the first housing (21) drives the propeller (50, 51) via the first shaft (31), the transmission (34, 44) and the second shaft (41). The first electric motor (60) is directly cooled to sea water surrounding the first housing (21).
