The Client and the Challenge
Last month, we completed a delivery of two 500 kVA containerized diesel generators to a gold mining operation in West Africa. The client, a mid-sized mining company expanding their processing capacity, needed reliable backup power for their entire operation — including the processing plant, camp facilities, and water pumping stations.
The challenge was straightforward but demanding: the generators had to arrive on site within 8 weeks, fully commissioned and ready to run. The location is remote — about 300 km from the nearest major port, with road conditions that are challenging during the rainy season. Everything had to be planned and executed precisely.
Generator Specifications
Based on the client power audit, we recommended two 500 kVA prime-rated units in a synchronized configuration:
- Engine: Cummins QSM11-G6, 6-cylinder turbocharged diesel
- Alternator: Stamford PI734H, 3-phase, 415V / 50Hz
- Control Panel: Deep Sea DSE8610 with synchronization module
- Canopy: 20ft ISO container, weatherproof, sound attenuated to 85 dBA at 1 meter
- Fuel Tank: Integrated 800L base tank + 2000L external day tank
- Cooling: Heavy-duty radiator rated for 50 degrees C ambient
The synchronized setup allows both units to share the load. If one generator goes down for maintenance, the other can carry critical loads independently.
Factory Inspection and Testing
Before shipping, we conducted a full load bank test on both units at the factory. Each generator ran at 100% load for 4 hours, with all parameters monitored and recorded:
- Voltage stability: within 1% of nominal
- Frequency stability: within 0.3 Hz of 50Hz nominal
- Coolant temperature: stable at 85 degrees C under full load
- Fuel consumption: 105 L/hr at full load (within specification)
- Exhaust temperature: within acceptable range
We also tested the synchronization function — both generators running in parallel, sharing load equally, with smooth transfer when one unit is taken offline.
Container Loading and Shipping
Both generators were loaded into 40ft high-cube containers at the factory in Changzhou. Each unit was secured with heavy-duty ratchet straps, wooden blocking, and foam padding to prevent any movement during ocean transit. The control panels were wrapped in waterproof film, and all access panels were sealed with tamper-evident tape.
The containers were loaded onto a vessel at Shanghai port, with an estimated transit time of 35 days to the destination port. We arranged marine insurance covering the full value of the equipment.
What Happens Next
Our field service engineer will meet the containers at the destination port to supervise offloading and initial inspection. He will then travel to the mine site to oversee installation, commissioning, and operator training. The entire process — from container opening to full operation — typically takes 5-7 days.
We also provide 12 months of remote monitoring support through the DSE control panel communication module, allowing our team to monitor generator performance and provide diagnostic support from our office in China.
Why Projects Like This Matter
Every generator delivery is more than just shipping equipment. It is about understanding the client actual needs, selecting the right configuration, and making sure everything works from factory to final installation. For mining operations in remote locations, generator reliability is not optional — it is the difference between meeting production targets and costly downtime.
