Since the Cat 3500 engine platform happens to be found in a lot of compilations, we wanted to feature not only the engine itself, but the vessels and sites that use the engine on a daily basis. Picture a story about a little crew, operating a little tugboat, towing giant boats from harbour to harbour in Alaska. Or a complete oil pipeline in Africa where the 3500 is the heart of the whole set up. What’s their story, what are their struggles? Quite intriguing, right?
