10 years of MaK VRT pressure charging: Variable turbine geometry optimises torque and reduces emissions

Hamburg, Germany – One of the most powerful tugs in the port of Hamburg has just celebrated its 10th anniversary – along with the innovative MaK VRT technology that has been part of her equipment since she went into service. The harbour tug “Michel”, owned by Petersen & Alpers, was commissioned in 1998. She owes her capacity to a well-coordinated crew and a twin-engine propulsion plant consisting of two medium-speed MaK 8 M 20 engines adjusted to 1,520 kW at 1,000 rpm and equipped with a Variable Radial Turbine (VRT). So, not only Michel but also MaK VRT technology has stood the test of time, particularly in tug applications…more at cat.com
