Vessel Specification
Corrosion & Remaining-Life What-If
Adjust operating conditions to see the live model-predicted corrosion rate and implied remaining life
What-if model: standardized Ridge regression, R² 0.56 on held-out fleet data (3.25 mpy MAE). Runs entirely client-side for instant feedback — see Model Insights for the full fleet-scale ensemble model used for official predictions.
Governing Damage Mechanism — General Corrosion
API 571 §4.2.1
Uniform thinning across the surface due to the process environment. Rate depends on fluid chemistry, temperature, and velocity.
Recommended inspection approach: UT thickness grid at fixed CMLs per API 510/572; trend over time to establish long-term rate.
