Funded by Innovate UK’s Clean Maritime Demonstration Competition, the D.E.E.P project combines additive manufacturing with digital twin technology to create smart propellers capable of monitoring their own performance. The initiative brings together Enki Marine Ltd, Stone Marine Propulsion, TWI, DEEP Manufacturing, Authentise, ASTM International, and Newcastle University. The Digitally Enabled Efficient Propeller (D.E.E.P) project aims to pioneer a new generation of marine propellers manufactured using advanced additive manufacturing (AM) processes, integrated with digital twin technology. This innovation will transform propellers from passive hardware into smart, cyber-physical systems capable of monitoring their performance throughout their operational life. The D.E.E.P concept has secured funding from Innovate UK, part of UK Research and Innovation (UKRI) through the Clean Maritime Demonstration Competition (CMDC6) to launch the Techno-Economic Feasibility Study of Manufacturing Digitally Enabled Efficient Propellers.
