Understanding LNG Pump Skids

An LNG pump skid is a pre-assembled unit that includes pumps, motors, controls, and other components necessary for transporting LNG. These skids are designed to enhance the efficiency of the LNG transfer process, making them integral in the export of LNG.

Key Specifications to Consider

When evaluating LNG pump skids, several important specifications should be taken into account:

  1. Capacity:

    • Determine the volume of LNG that needs to be moved per hour.
    • Assess peak flow requirements to avoid bottlenecks during high-demand periods.
  2. Pressure Ratings:

    • Ensure that the LNG pump skid is capable of handling the necessary operating pressures.
    • Consider the maximum discharge pressures that the application may require.
  3. Material Construction:

    • Select materials such as stainless steel or carbon steel, which are resistant to corrosion and have high strength.
    • Verify compatibility of materials with LNG's cryogenic properties to prevent leaks.

Energy Efficiency and Operational Cost

Choosing LNG pump skids that are energy-efficient can lead to significant cost savings:

  • Look for pumps with high efficiency ratings and design certifications.
  • Evaluate lifetime operational costs, factoring in maintenance requirements and energy consumption.
  • Consider variable frequency drives (VFDs) for optimizing energy use during different operational loads.

Reliability and Maintenance

Reliable LNG pump skids are crucial to minimize downtime:
