Tank Inspection & Engineering Services
API 653 Tank Inspections
Internal and external inspections per API 653, including comprehensive checklists covering shell, floor, roof, foundation, appurtenances, and ancillary systems.
Floating Roof Seal Inspections
Detailed inspection of primary and secondary seal systems on floating roof tanks to identify wear, gaps, and emissions concerns.
Tank Settlement Surveys & Engineering
Precision survey services including edge settlement, bottom settlement, and out-of-plane shell settlement measurements - with engineering evaluation per API 653 criteria.
Tank Strapping Calibrations
Accurate tank capacity calibration measurements for custody transfer, inventory management, and regulatory compliance.
3D Laser Scanning
High-resolution 3D scanning for dimensional verification, deformation analysis, and as-built documentation of tank geometry.
In-Service Tank Inspections with Robotics
Robotic inspection technology allows us to assess tank floor and shell conditions while the tank remains in service - reducing downtime, eliminating confined space entry risks, and providing actionable data without taking the tank out of operation.
Third-Party Inspections During Construction & Repairs
QA/QC oversight during new tank construction, major repairs, and alterations to ensure workmanship meets API 650/653 and owner specifications.
