Retrofit to Dual Fuel Operation for Fred Olsen High-Speed Vessel
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 Norwegian shipping line Fred. Olsen S.A. who chose HEINZMANN as a competent and innovative supplier of dual-fuel systems.
The dual-fuel system is operated by the latest version of HEINZMANN's MVC 01-24 EFI-controller, actuating the specially developed, double-walled MEGASOL 200 II gas admission valves. This offers very flexible system configuration in order to achieve the best possible adaptation for any application. Together with an intelligent air path management controlled by HEINZMANN’s wastegate valve WG 70, it was possible to operate the engine with a conversion ratio up to 90% gas. As a result the calculations from the comprehensive simulation works executed by AVL were met exactly. The reliable ARIADNE Knock Control System was installed to operate the converted engine at the highest efficiency limits.
