Propulsion: Two ‘ABC’ type 8 MDZC 4-stroke-trunk-type diesel engines totalling 3.700 kW at 1.000 rpm, driving two ‘schottel’ type SRP1515EP full azimuth propellers in ‘kort’ nozzles. Propeller thrust and direction are bridge-controlled by means of two individual (PS/SB) control stations, with separate direction and rpm settings, resulting in fast and accurate manoeuvrability. The ‘kort’ nozzles guarantee a high pull/power ratio.
   
Deck Equipment: Robust waterfall winch ‘Brusselle’ type SLH-130/50/2-1 with one harping head on aft deck. Brake holding 130 tons, dynamic: 44 tons at 10 m/min, slack rope speed 50 m/min.

Brake holding: 130 tons, dynamic: 44 tons at 10/min, slack rope speed: 50 m/min.
Both towing winches are remote controlled from the bridge.
For extreme safety, all our winches have an emergency stop and a ‘letgo’ button, that can even be operated in a total black – out situation.
   
Auxiliaries: Each tug has two ‘Scandia DS 9 95M’ (196 kW) diesel engines, driving 180 kVA alternators 3x 380 V – 50 Hz. One genset for harbour duties: 90 kVA.
Hydraulic pumps for propulsion system are main engine driven.
