Ricardo, now a company in its 100th year, has cooperated with an engine manufacturer to design a completely new medium speed engine platform to address this market. On December 25th 2014, just 18 months after commencing the initial layout design calculations, a production intent full scale engine achieved its first fired run at the engine manufacturer's development test facility. The engine has a market entry power rating of 530kW/cyl, initially employing single stage turbocharging, and is designed to operate at up to 250bar peak firing pressure. The initial production engine will run on HFO/MDO with further Natural Gas and Dual Fuel variants already under development, supported by an architecture of common major components. Extensive use of analysis and simulation tools enabled the engine design engineers to optimise the strength and durability of the engine design whilst at the same time enabling efficient manufacturing by a localised supplier base. Ease of assembly, ease of maintenance and long service intervals are also features of the design which contribute to a competitive capital cost per MW. Competitive specific fuel oil consumption of the production intent engine has been measured on the development test facility over a wide range of operating loads, confirming the successful use of engineering analysis tools to minimise friction and the simulation-led optimisation of both gas exchange and combustion systems. Combined with the competitive first cost this engine therefore brings highly competitive total cost of ownership to the world powerplant market within a robust and maintainable technology package. This paper will seek to provide an overview of this new medium speed engine including the technologies selected to be appropriate for the target market and the state of the art engineering processes that underpinned the design.
