MARINE PROPULSION • THOUGHT LEADERSHIP “Even if the future of shipping some- times seems less clear today than it did 10 years ago, operational and fuel ? exibility remains one of the key elements to reduce in- vestment risks in cutting edge technology. We need to ensure that our solutions work as well in the future as they do today. Flexibility is key in meeting that promise.”
