Project Examples

Ricardo has a wide range of project examples delivered to the marine industry

The following project examples show a selected basis of our work and expertise

 
Large Marine Engine Development
  • CNG variant of V16 32cm bore diesel engines
  • Output of approximately 8MW
  • High thermal efficiency
  • Meets the latest emissions legislation
  • Integrated development testing with client (HHI)
 
Improved Thermal Efficiency
  • The compression and combustion /expansion processes are separated in different cylinders
  • The charge air is compressed isothermally, by spraying a large volume of water into the cylinder during compression to 100 bar
  • Potential system efficiency 60%
 
Innovative Stern Drive
  • Objective to achieve reduced cost, increased efficiency compared to conventional Z-drive
  • Concept design of down-leg drive; shift and reversing mechanisms
  • Production of layout drawings, including component selection & system level FMEA study
 
Increased Durability & Refinement
  • Dynamic analysis and scheme design for wet multiplate clutch in marine workboat transmission
  • Consideration of shift energy and power for aggressive engagement and high energy duty
  • Advice on lubrication and clutch cooling strategies
 
Design & Thermal Optimization
  • Detailed mechanical and thermal analysis of a high performance 250mm bore engine
  • Optimization, CAE, FEA, CFD
  • Meet durability targets of 15000hrs for heads on HFO and 30000hrs for cylinder components
 
Brand Attribute Development
  • 55 foot Luxury motor cruiser with Twin Volvo Penta D13-900 diesel units
  • Vibration survey of deck, engine, hull & propeller shaft
  • Material lay-up issue in build identified & resolved using additional structural materials at engine mount and P-bracket attachments
