AES Mong Duong Power Plant: Maintaining critical lifting equipment in Vietnam

AES Mong Duong Power Company Limited, a subsidiary of AES Corporation, operates the Mong Duong 2 BOT Power Plant in Quang Ninh Province, Vietnam. As Vietnam’s first and largest coal-fired power plant using advanced pulverized coal boiler technology, it plays an important role in supplying electricity to the national grid and meeting the country’s growing energy demand.

Role of overhead crane in Mong Duong 2 power plant operations

Mong Duong 2 generates electricity by converting heat from coal combustion into steam, which drives turbines connected to generators. This process involves large and heavy equipment—such as turbines, boilers, generators, and coal handling systems—that must be installed, maintained, and periodically serviced. Power plants typically shut down individual units every 12 months for scheduled maintenance. During these periods, cranes handle the removal and installation of components that can weigh several hundred tons. At Mong Duong 2, the lifting equipment includes single- and double-girder cranes with wire rope hoists. These cranes are located across several areas, including the water pumping port, turbine compressor, boiler area, workshop, and warehouse. Their lifting capacities range from 10 to 90 tons. To maintain reliable performance of this equipment, AES Mong Duong works with Konecranes under a preventive maintenance program covering more than 123 cranes and hoists throughout the facility. The program helps keep the lifting equipment in good condition and reduces the risk of failures during maintenance periods.

Preventive maintenance for reliable operation

To support safe and consistent crane performance across the plant, Konecranes provides a Preventive Maintenance Program that includes regular inspections, maintenance work, and technical support. Konecranes technicians visit the site regularly to check the equipment, perform maintenance, and share detailed reports with clear recommendations. This helps AES Mong Duong identify issues early, plan maintenance in line with plant schedules, and avoid unplanned downtime during shutdowns.

“Our long-term partnership with Konecranes has been vital in maintaining safe and reliable crane operations. Regular inspections and scheduled maintenance have significantly lowered the risk of unexpected breakdowns, helping us avoid costly downtime and keep the plant running smoothly.”

Long-term partnership resulting in Operational benefits

Long-term partnership Konecranes has worked with AES Mong Duong since 2015, supplying lifting equipment for key areas of the plant and providing original spare parts, maintenance services, modernization, and hoist upgrades. Over the years, several improvements have been made to increase reliability and performance, including component replacements, control system updates, and adjustments to meet operational needs. “We replaced the busbar system with a festoon system to address wear and tear issues, featuring improved cable support, flexibility, and more durable components. This upgrade significantly reduced the risk of cable entanglement, abrasion, and failure. We also carried out retrofits including new hook assemblies and updated electrical control systems, along with replacement components such as rope guides, brake controls, and emergency stop buttons,” said Nguyen Tuan Anh, Account Manager, Konecranes Vietnam. 
The maintenance program supports plant operations by keeping cranes available when needed. During planned outages, reliable crane operation is essential for completing maintenance safely and on time. This preventive approach allows AES Mong Duong to detect potential problems early, plan repairs in advance, and maintain steady operations. Through its cooperation with Konecranes, AES Mong Duong has reduced downtime, improved safety, and extended the service life of its cranes—supporting the reliable production of electricity for Vietnam’s national grid.
