One example of composite materials being used successfully in shipbuilding is at Uljanik, one of the partners of the European union-sponsored Realization and Demonstration of Advanced Material Solutions for Sustainable and Efficient Ships (RAMSSES) project.
The Croatian shipyard has used composites in deck plating on Siem Car Carriers' 7,000-ceu Siem Cicero (built 2017), saving more than 200 tonnes in weight and enabling dozens more vehicles to be carried.
