LNG Commissioning Data Integrity and SIS Alignment

Overview

Our solution streamlined the commissioning process for an LNG facility preparing for its first gas cooldown cargo. By creating a comprehensive asset registry and synchronizing Safety Instrumented System (SIS) tags across engineering and operational databases, we ensured data integrity and safety compliance. This alignment minimized operational risks and accelerated readiness for LNG production.

Challenge

Commissioning a new LNG facility involves thousands of instruments and safety-critical components. Prior to our intervention, the client faced:

  • Fragmented data sources: Equipment and SIS tags were scattered across multiple systems, leading to inconsistencies.
  • Risk of misalignment: Discrepancies between engineering design and operational databases could compromise safety and delay startup.
  • Manual verification burden: Engineers lacked a centralized, accurate registry, making validation time-consuming and error-prone.

Solution

  • Centralized registry creation: Built a unified database capturing all equipment and SIS tags.
  • Data synchronization: Ensured SIS tags were accurately reflected in both the registry and control systems.
  • Integrity checks: Implemented validation processes to confirm alignment between design documents and live systems.

Key Benefits

  • Operational readiness: Enabled smooth commissioning for the first LNG cooldown cargo.
  • Safety compliance: Reduced risk of SIS misconfigurations, ensuring adherence to standards.
  • Efficiency gains: Eliminated redundant manual checks, accelerating project timelines and reducing human error.
