Turkish shipbuilder Uzmar has completed ice-class, hybrid-propulsion tug Hermes to support ships using Denmark’s largest container port
Uzmar built Hermes to a Robert Allan Ltd RAmparts 3000 design for the Port of Aarhus. It left the shipyard in early September on its maiden voyage to Denmark.
Hermes is an ice I class tug with mechanical-hybrid propulsion to reduce fuel consumption and emissions. It has a pair of Cummins QSK60 engines, compliant with IMO Tier II emissions requirements, each developing 2,013 kW of power.
They drive two Schottel RudderPropellers type SRP 430 azimuth thrusters with fixed-pitch propellers of 2.5 m diameter. An additional driveshaft links the port and starboard thruster units for Schottel’s Sydrive-M mechanical hybrid solution.
This allows one engine to be shut down when the tug is not assisting a ship, while the other engine provides power to both thruster units. Hermes has a free-running speed of 12.5 knots and bollard pull of 65 tonnes.
In another configuration, power from the starboard engine can be dedicated to a large fire pump mounted to the front end of the engine. At the same time, port engine power is committed to both thrusters giving the master full manoeuvring control of the tug while holding it in the best position for fire-fighting.
