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:

1. Active Magnetic Bearings

   • Eliminates oil contamination → Zero hydrocarbon emissions

   • Reduces maintenance downtime by 200 hours/year

2. 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.”
– KEEPWIN Engineering Lead, Bushehr Project

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:

Key Enabler: Modular compressor design allowed retrofit without terminal shutdown.

Why Offshore Terminals Demand This Tech

1. Corrosion Resistance

   • Ceramic-coated impellers withstand salt spray (tested at 2000hrs salt-fog)

2. Explosion Safety

   • ATEX Zone 1 certification (no sparks from magnetic levitation)

3. 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.”

3 Industries Revolutionized by BOG Recovery

1. LNG Export Terminals

   • Recaptured gas liquefied for extra revenue

2. FSRU Vessels

   • Stabilizes tank pressure during offshore regasification

3. Bunkering Stations

   • Enables small-scale LNG transfers without venting

Future-Proof Your Terminal Today

While hydrogen-ready compressors dominate headlines, BOG recovery remains LNG’s most immediate ROI opportunity. KEEPWIN’s systems pay back in ≤18 months via:

• Gas resale revenue

• Slashed maintenance budgets

• Carbon credit generation
