What is an In-Service API 653 inspection?

An in-service API 653 inspection is a tank floor integrity inspection performed using remotely operated vehicles. The advantage is the tank can remain full and in-service over the course of the inspection.


In a traditional API-653 floor inspection the tank is drained, cleaned, and degassed. This requires the tank to be taken out of service and in some cases, out of production. An in-service API 653 inspection can be performed at any time and has little impact on the facility and its operations.
