Diesel-Electric Propulsion for Offshore

Throughout that period, Cummins Marine has been a leader, supplying more than 900 diesel electric packages since delivering its first genset 2003. Early adopters of this flexible propulsion technology included the US firm Rigdon Marine with twenty vessels and France-based Bourbon Offshore with over 100 vessels. In late 2011 Aries Marine built two STX-designed Tiger Shark Class PSVs. After nine months operating in Mexico, one of their vessel engineers, Darrell Bickham, enthused over the performance. “We only put enough engines on line as we need for the job. We can stand by the rig outside the 500-meter zone on one of our four Cummins QSK60-powered generators. Traveling we can make 10 knots with only two operating at 50 to 60 percent of their rated power.” Captain Philip Munsch added, “If we get into weather we can bring on three or even four engines as required. But they are always running at a steady 1,800 RPM with no revving up and down so crew comfort and safety is improved because of the reduced fatigue.”
