Hybrid Propulsion for New Fairplay Tugs
The Fairplay fleet in Rotterdam welcomed two new members: The hybrid tractor tugs Fairplay IX and Fairplay XI, each equipped with a Schottel hybrid propulsion system including two Schottel Rudderpropellers SRP 4000 with hybrid gearboxes, two electric motors and an integrated steering control system, specialized for hybrid propulsion. The installed hybrid propulsion concept enables the Fairplay tugs to operate with an optimal power output, according to the propulsion manufacturer. At part load, the electric motors (600 kW each) suffice while the two MTU diesel engines (2,240 kW each) are employed for operation at full load. Here, the electric motor can be switched on to provide additional power. The 29m long tractor tugs have a bollard pull of 90t and travel at a maximum speed of 13.5 knots.
