Selecting the right firm to conduct an API 653 inspection is a critical decision for any tank owner or operator. This inspection assesses the integrity of aboveground storage tanks, ensuring their safe and compliant operation.
The quality of the inspection directly affects your tank’s reliability, regulatory standing, and your facility’s operational planning. A thorough evaluation requires specific expertise, a detail-oriented approach, and a clear understanding of the 653 API standard.
Verify Certifications and Qualifications:
Confirm that the company employs inspectors who hold active API 653 certification. This certification, issued by the American Petroleum Institute, demonstrates individual competency.
Ask for proof of these credentials. Also, inquire about the company’s overall accreditation and insurance. A reputable inspection firm carries appropriate liability and worker’s compensation insurance to protect all parties involved in the project.
Assess Relevant Experience:
Examine the company’s direct experience with tanks similar to yours. Consider their history with tanks of comparable size, construction material, and product service. A firm familiar with chemical storage tanks might differ in its approach from one specializing in crude oil or water tanks.
Request case studies or references for past projects. Speaking with previous clients offers insight into the inspector’s thoroughness, reporting clarity, and professional conduct on site.
Review Their Inspection Methodology:
A strong inspection company provides a clear, documented plan. Ask about their proposed procedures for tasks like ultrasonic thickness testing, settlement evaluation, and critical flaw assessment. Understand what non-destructive examination (NDE) techniques they employ and the qualifications of the technicians performing this work. Their methodology should follow a structured process from pre-inspection planning to the final detailed report, aligning with API 653 requirements.
Evaluate Reporting and Communication:
The final inspection report is a vital document for your records and regulatory compliance. Request sample reports to judge their clarity, depth, and organization. A good report presents findings, data, and recommendations in a way that engineering and management staff can readily understand.
You should also consider their communication style during the proposal process. A company that responds promptly and explains complex items clearly will likely maintain that standard throughout your engagement.
Consider Project Management and Logistics:
An efficient inspection minimizes tank downtime. Discuss how the company manages scheduling, on-site personnel, and equipment mobilization. Understand who your main point of contact will be and their process for addressing unforeseen issues during the inspection. A firm with solid project management coordinates effectively with your team, adheres to agreed timelines, and keeps the project moving forward smoothly.
