\"Pipeline<\/figure>\n

Three SOFIMO PS-5060PV units were deployed at a large-diameter pipeline repair site, powering high-demand automated welding equipment. By combining battery storage with diesel generator charging, the project is expected to reduce annual fuel costs by approximately 30%.<\/strong><\/p>\n

Project Overview<\/strong><\/h2>\n

Industry:<\/strong> Oil & Gas \/ Pipeline Construction and Repair
Welding Equipment:<\/strong> Xionggu 380V Automated Pipeline Welding System
Applications:<\/strong> Induction Preheating, Fill and Cap Welding, Grinding
Power Equipment:<\/strong> 3 \u00d7 SOFIMO PS-5060PV Industrial Battery Storage Units
Unit Specifications:<\/strong> 50kW AC Output \/ 59.9kWh Battery Capacity
Power Configuration:<\/strong> Diesel Generator Charging + Battery-Powered Operation<\/p>\n

01 | Project Background: Reliable Power for Large-Diameter Pipeline Welding<\/strong><\/h2>\n

At a remote oil and gas pipeline repair site, the crew used a Xionggu 380V automated welding system for induction preheating, fill and cap welding, and grinding.<\/p>\n

\"Battery<\/figure>\n

The multi-torch welding system operates at power levels reaching tens of kilowatts, while induction preheating requires substantial power over short periods. These processes demand reliable three-phase power and the ability to handle changing loads.<\/p>\n

Traditionally, diesel generators supply power directly to welding equipment. However, fluctuating loads and extended operating hours can increase fuel consumption and operating costs.<\/p>\n

To improve energy efficiency without compromising welding operations, the project team introduced SOFIMO PS-5060PV industrial battery storage units alongside its existing diesel generators.<\/p>\n

02 | On-Site Application: 50kW Battery Power for 380V Automated Welding<\/strong><\/h2>\n

Three PS-5060PV units were deployed, each delivering 50kW of rated AC output<\/strong> with a 59.9kWh lithium iron phosphate (LFP) battery<\/strong>, supporting three-phase 380V industrial equipment.<\/p>\n

\"Crew<\/figure>\n

During construction, the PS-5060PV supplied power for induction preheating, multi-torch automated fill and cap welding, and associated grinding operations.<\/p>\n

\"SOFIMO<\/figure>\n

With its high-power AC output and capacity to accommodate varying equipment loads, the PS-5060PV supports demanding industrial applications beyond the capabilities of many smaller battery power systems.<\/p>\n

Under actual site conditions, a fully charged unit could support multiple complete pipe-joint welding cycles. The crew coordinated equipment use and recharging according to welding progress and remaining battery capacity.<\/p>\n

03 | Hybrid Power Supply: Improving Diesel Generator Efficiency<\/strong><\/h2>\n

The project adopted a hybrid configuration in which diesel generators recharged the PS-5060PV units, while the battery systems supplied power directly to welding and auxiliary equipment.<\/p>\n

\"PS-5060PV<\/figure>\n

This arrangement separated generator charging from fluctuating welding loads, allowing the crew to schedule recharging around construction activities and helping reduce prolonged low-load generator operation.<\/p>\n

Designed for demanding outdoor environments, the PS-5060PV also features a rugged industrial enclosure with an IP54 protection rating<\/strong>, providing protection against dust ingress and water splashes.<\/p>\n

04 | Project Results: High-Power Welding with Approximately 30% Lower Fuel Costs<\/strong><\/h2>\n

The three PS-5060PV units successfully supported the 380V automated welding system throughout key pipeline repair operations, including induction preheating and multi-torch welding.<\/p>\n

Each unit’s 50kW output and 59.9kWh battery capacity enabled multiple welding cycles per charge, with diesel generator charging supporting continued operation.<\/p>\n

Based on the project team’s comparison of conventional diesel-generator power and the hybrid battery storage configuration, annual fuel costs are projected to decrease by approximately 30%.<\/strong><\/p>\n

Reduced diesel consumption may also help lower associated carbon emissions, aligning with the growing demand for energy-efficient, lower-emission construction practices.<\/p>\n

For pipeline contractors, this approach provides a practical way to meet high-power welding requirements while improving fuel efficiency and managing long-term operating costs.<\/p>\n

05 | Proven Industrial Experience for Demanding Jobsites<\/strong><\/h2>\n

SOFIMO Power has extensive experience in industrial portable power solutions, with proven applications in oil and gas pipelines, industrial maintenance, municipal repairs, and tunnel construction.<\/p>\n

The successful deployment of the PS-5060PV in large-diameter pipeline welding demonstrates SOFIMO’s expertise in high-power industrial energy storage.<\/p>\n

Combining in-house engineering with real-world project experience, SOFIMO delivers battery power solutions tailored to equipment loads, operating environments, and on-site charging requirements.<\/p>\n
