Test bench runs on a CATERPILLAR 3618 engine have recently been successfully completed for the world’s first dual-fuel conversion on a marine high-speed propulsion engine. The project was initiated by Spanish shipping line Fred. Olsen S.A. who chose HEINZMANN as a competent and innovative supplier of dual-fuel systems and aquired AVL, a specialist in development of complete powertrain systems, as a partner for executing engine design, simulation, test bed planning as well as for performance and emission development. As part of the GAINN4SHIP INNOVATION Program, the dual-fuel conversion project is co-financed by the European Commission.
