Urisol Inc. specializes in visual testing (VT) and shutdown / turnaround (T/A) inspection coordination at refineries and chemical plants throughout Japan. Client names and specific plant identities are withheld under confidentiality agreements. This page highlights representative projects from the last five years (2021 onward).
Refinery Turnaround (TAR) Projects
Major refinery — Outsourced VT, multiple process units
External visual inspection of piping, vessels, and support structures across multiple refining process units. Documented corrosion, insulation damage, and flange condition; prepared damage-assessment reports.
Major refinery — Heavy oil thermal cracker T/A
Visual inspection during turnaround of a heavy-oil thermal cracking unit producing naphtha, gas oil, and coke. Inspected drum shells, piping flanges, CUI-prone areas; evaluated oxide-scale and creep deformation on high-temperature components.
Major refinery — Integrated refining / vacuum distillation T/A
Inspection of integrated process units and vacuum-distillation systems during turnaround. Handled multiple units in parallel, from anomaly prioritization and recording through to final reporting.
Major refinery — Turnaround VT support at two sites
VT support work at refinery turnarounds in Kanto and Tokai regions. External inspection of piping, vessels, and structures; corrosion / deformation / leak-mark recording and integration into the repair list.
Chemical Plant Turnaround Inspection
Major chemical plant — Turnaround VT (two consecutive years)
Turnaround inspection of chemical-process equipment in two consecutive years. Corrosion assessment of piping and vessels under corrosive atmospheres, heat-exchanger tubesheet visual evaluation, and CUI surveys. Continuous engagement enabled tracking of degradation trends.
Major chemical plant — Turnaround VT & NDE
Visual inspection and NDE support during chemical-process turnaround. External inspection of reactors, distillation columns, heat exchangers, and piping, combined with ultrasonic testing at areas flagged for closer evaluation.
Inspection Coordination / Thickness Management / Data Integration
Major refinery — Inspection coordination (SDM), catalytic reformer system
About four months of inspection-coordination work across the catalytic-reformer unit chain. Managed inspection planning, scheduling, crew coordination, progress tracking, and record-quality review for the full turnaround inspection workflow; compiled final reports.
Major refinery — Hydrocracker thickness management
Thickness-management work during hydrocracker turnaround. Collected and organized thickness data on piping and reactor nozzles in high-temperature / high-pressure hydrogen service; supported corrosion-rate evaluation and next-inspection planning.
Major manufacturer — Production-line equipment maintenance (approx. 5 years)
Approximately five years of continuous equipment-maintenance work on a metal-processing production line. Periodic furnace repair, SPM-based vibration diagnostics on rolling-mill and motor bearings, and support of preventive-maintenance planning. Long-term engagement enabled systematic tracking of equipment-degradation trends.
This page highlights representative projects from 2021 onward. Earlier engagements (data-integration work, distillation-unit turnarounds, and chemical-plant inspections from 2014–2020) are available on request.
