Recently, the waste heat power generation system provided by CSSC’s 711th Research Institute for the /3100-meter lane luxury ro-ro passenger ship (“VIRGO”) successfully completed its sea trial tasks and passed the joint inspection by the shipyard, shipowner, and RINA (Italian Naval Register). This marks the third collaboration between the 711th Research Institute, Guangzhou Shipyard International (GSI), and MSC Mediterranean Shipping Group on this series of ro-ro passenger ships. The waste heat power generation systems installed on the two previously delivered ro-ro passenger ships have been operating safely and stably to date.
This ro-ro passenger ship adopts a dual-fuel (MGO+LNG) power system, combining environmental friendliness with high performance, making it suitable for both international short and long-haul routes. This project represents the first time that the marine waste heat power generation system independently developed by the 711th Research Institute has achieved a matching design with a dual-fuel engine.
Starting from the top-level planning of the entire ship’s energy system, the two parties conducted a comprehensive evaluation and integrated optimization of the main engine operating load, waste heat resources, ship thermal demand, and power generation system, successfully achieving efficient coordination between the waste heat recovery system and the main engine, heat users, and the ship’s power grid. The system has a rated power generation capacity of over 900kW, which can help the ship reduce its Energy Efficiency Design Index (EEDI) by more than 5%, significantly improving the overall energy efficiency level.
During the sea trials, the waste heat power generation system passed the endurance tests and unattended machinery space (UMS) tests in both fuel oil and gas modes on the first attempt, fully demonstrating its excellent stability and reliability.
As a key R&D unit for domestic marine power systems and energy-saving equipment, the 711th Research Institute actively serves the national “Dual Carbon” strategy, deeply cultivates the field of ship energy-saving technology, provides global customers with advanced and reliable integrated energy-saving and carbon-reduction solutions, and contributes to promoting the green transformation of the shipping industry.
