Two six cylinder X35 engines successfully completed the Factory Acceptance Trials last month in two separate facilities, one at 3.MAJ Engines & Cranes, Croatia, and the other at Yuchai Marine Power Co., Ltd. (YCMP), China. The trials were witnessed by representatives of the Classification Society, the shipbuilder, and the shipowner.
