First application of the Residual Life Assessment (RLA) Toolkit for an LNG Liquefaction Plant transitioning from early-life reliability into a mature operational phase — establishing a structured condition baseline and ageing model to support future integrity assessments and life extension studies.
The LNG Liquefaction Plant was moving from an early-life reliability phase into a more mature operational phase, with ageing equipment and associated integrity risks becoming increasingly prominent. The operator required a structured first-pass condition assessment to form the baseline for further integrity assessments and life extension studies. Inconsistency and misalignment in the CMMS — including equipment tags missing from the master equipment list — presented an additional data quality challenge.
Optimal conducted the initial review stages of the RLA Toolkit in three structured phases. First, a Desktop Asset Verification (DAV) was performed to identify equipment within the RLA scope and verify data against the CMMS and master equipment list. Second, a Historic Maintenance Review was carried out to establish ageing and degradation mechanisms for each equipment item and assign condition scoring. Third, all assessment data was captured in the RLA Toolkit to provide a structured foundation for future studies.
The operator received a structured, populated RLA Toolkit providing the first systematic condition baseline for the plant. The assessment resolved CMMS data gaps, established degradation mechanisms for key equipment, and created a reusable framework that can be updated through operational phases to identify bad actors, prioritise maintenance and support future life extension submissions.
