A dual parallel organic Rankine cycle (ORC) system is proposed for the efficient waste heat recovery of marine applications, which present a relatively large variation of waste heat relative to sailing conditions. Simulations for single and dual ORC systems are conducted with a wide range of heat input. The performance results are compared to evaluate the benefits of the proposed dual configuration. Annual total power outputs produced by single and dual ORCs are calculated to assess the appropriateness of applying the dual ORC to a marine engine by using four models of fuel consumption distribution based on the actual sailing data of a container ship. Results demonstrate the ability of dual ORC to produce more total power output than the single ORC.
