MAN tests upgrade

MAN B&W is testing an upgraded version of its 480mm bore medium-speed engine. A spokesman for the company confirmed that the prototype model is undergoing long-cycle endurance tests in Augsburg, Germany. He says the improved version includes “decisive design changes”. The Motor Ship understands these include strengthened pumps and cam drive to allow the injection of more water, thus further reducing NOx emission levels. The engine may be launched under a new name and, on the basis of trial results, could be available for commercial sale within the next few months.
