Every year, LNG terminals lose $2.2 million to boil-off gas (BOG) evaporation during storage and transfer. Traditional piston compressors exacerbate this with frequent start-stop cycles and lubricant contamination. Here’s how next-gen BOG recovery technology tackles these issues – with hard data from operational terminals.
The Core Innovation: Magnetic Bearings + VFD Control
KEEPWIN’s solution integrates two breakthrough technologies:
-
Active Magnetic Bearings
-
Eliminates oil contamination → Zero hydrocarbon emissions
-
Reduces maintenance downtime by 200 hours/year
-
-
AI-Driven Variable Frequency Drives (VFD)
-
Adjusts compressor speed to real-time BOG volume
-
Cuts energy waste during low-load periods by 35%
-
“Traditional units consume 30% extra power during idle cycles. Our system sleeps when not needed.”

Iran Case Study: 100% Recovery at Bushehr Terminal
In 2024, Iran’s Bushehr LNG Terminal faced:
-
Daily BOG loss: 1.2 tons (≈ $4,300/day)
-
Frequent shutdowns: Every 45 days for bearing replacement
After installing KEEPWIN’s system:
Métrica | Before | After | Improvement |
---|---|---|---|
BOG Recovery Rate | 78% | 100% | +22% |
Energy Consumption | 0.48 kWh/Nm³ | 0.29 kWh/Nm³ | -40% |
Maintenance Cycles | 45 days | 400+ days | 8.9x longer |
Noise Level | 92 dB(A) | 68 dB(A) | -26% |
Key Enabler: Modular compressor design allowed retrofit without terminal shutdown.
Why Offshore Terminals Demand This Tech
-
Corrosion Resistance
-
Ceramic-coated impellers withstand salt spray (tested at 2000hrs salt-fog)
-
-
Explosion Safety
-
ATEX Zone 1 certification (no sparks from magnetic levitation)
-
-
Remote Control
-
IoT sensors predict seal failures 300+ hours in advance
-
A Saudi Aramco audit confirmed:
“Zero lubricant leaks = zero fire risk in compressor rooms.”
