Independent assurance
for critical assets
Seqto is a French-based independent inspection, consulting and technical manpower company serving the oil & gas, petrochemical, power and industrial manufacturing sectors. We exist for one reason: to give asset owners objective, documented proof that their equipment, suppliers and processes are fit for purpose.

Our purpose
Zero defect.
Zero risk.
Industrial failures are rarely sudden. They are the result of an unverified weld, an unchecked supplier, a missing certificate or a control that nobody audited. Seqto was created to close those gaps before they cost money, downtime or lives.
We operate as a genuinely independent third party. Our inspectors report what they find, our consultants recommend what the evidence supports, and every conclusion is traceable to a recognised code or standard. That independence is the whole value of what we sell.

View services →Our approach
How we run an assignment
The same disciplined method applies whether we are witnessing a hydrotest or auditing a supplier’s governance framework.
Define
We agree the scope, applicable codes, acceptance criteria and reporting format in writing before mobilising.
Verify
Certified specialists carry out the inspection or audit on site, using calibrated equipment and documented procedures.
Report
Findings are issued with photographic evidence, code references and a clear conformity statement.
Improve
We track corrective actions to closure and feed the lessons back into your quality system.
