The present invention provides a propulsion system for a vessel such as a service vessel or supply vessel. The vessel has a hull (10) with a midship portion (12) and a stern portion (14). The propulsion system comprises two propulsion units (30, 30^) fixedly mounted to the hull (10) on opposite sides of a centre line of the hull (10) at the stern portion (14), each of the propulsion Units (30, 30·.) comprising a housing carrying a propeller (48) externally of the housing. The housing further defines an interior vol¬ ume in which a drive machinery (52, 54, 56) is provided for driving the propeller 48 via a propeller shaft (48), the interior volume being open to the interior of the hull (1.0). A vessel comprising the propulsion system and a method of retrofitting a hull (10) with the propulsion system are also provided. |
