The vessel is powered by five Cummins KTA-50-M2 diesel engines rated at 1,800 bhp @ 1,900 rpm, each coupled with a Twin Disc, model MG-6848, 2.93:1 reduction ratio gear. Each engine turns a four blade Teinbridge 54 x 54-in. Nibral propeller providing a light ship speed of 25 knots and fully loaded speed of 20 knots. The vessel, to enhance manueverability, features a Thrustmaster 400 hp azimuthing thruster, powered by a Cummins N-14-M diesel engine. Twin 99KW Cummins 6BT5.9-G2 generators supply electrical power for the vessel's services and a Cummins 6CT8.3 diesel engine powers the Leroi WE 150 IIM - 80 PSI bulk compressor.
