MLNG 28" Steam Line Remediation - Ovolifts Methodology

A large-scale LNG plant in Malaysia experienced displacement of a 28” steam pipe, causing extensive damage to its culvert-based support system, including broken guides and stops. Our engineering team was tasked with the critical challenge of restoring the pipe to its original position while safely managing the significant stored energy within the system. Our approach began with measuring the pipe displacements, then conducting a comprehensive stress analysis on the pipe circuit. By measuring the pipe's exact displacement and comparing it to its as-built condition, we precisely calculated the magnitude and location of the external forces at play. This analysis was crucial for developing a safe, step-by-step remediation plan. The process was then meticulously planned and executed: 1. Neutralizing Stored Energy: We anchored the pipe at key locations, as identified by the stress analysis, to safely contain the internal forces and prevent the pipe from "springing back" when damaged supports were removed. 2. Repositioning the Pipe: With the pipe secured, we were able to safely remove the damaged supports. We then used controlled lifting and pulling forces to maneuver the displaced pipe section back into its correct position. 3. Final Restoration: Once the pipe was properly aligned and new supports were in place, we carefully released the tension on the anchors and lowered the lifting devices, allowing the piping to return to its original configuration without incident. The plant's Executive Team tasked Ovolifts with building this animation to describe in detail the remediation steps prior to project execution. This methodical and data-driven approach, powered by our detailed stress analysis, ensured the safe and effective restoration of this critical infrastructure.
