Ready to run LNG cargo pumps like a seasoned pro? This episode lays out a clear, uncompromising roadmap to safe, efficient operation—no guesswork, no grey areas.
What you’ll learn:
Submerged Motor Design: Why the LNG you’re pumping is also your coolant and lubricant—and why microns of precision matter.
Safety-Critical Pre-Start Checks: The hard numbers and the “why” behind them—cargo tank liquid level above 459 mm, motor insulation resistance > 5.0 MΩ, and setting the discharge valve to ~15% open to ensure flow and prevent starvation damage.
Protection Systems That Save Equipment: How undercurrent protection trips at 9 A for 10 s to prevent cavitation—and what that tells you about suction loss.
Advanced Troubleshooting with IAS: Correlate pressure and current like a diagnostician. Spot locked-rotor and reverse-rotation starts from current behavior in the first 10 seconds.
Operational Discipline: The restart rules that protect windings—why a 30-minute wait after an emergency trip isn’t optional.
Who it’s for:
Marine engineers, ETOs, cargo engineers, and operators working with LNG cargo systems
Safety leaders and technical trainers aiming for zero incidents and zero equipment damage
You’ll walk away with the exact checks, thresholds, and decision rules to operate with precision and confidence—every start, every time.
