Enhanced Survey File and tanker structural condition
What is being checked
The inspector is checking whether the Enhanced Survey File and Coating Technical File form a complete structural history for an oil or chemical tanker and whether records and visible condition reveal unresolved hull, tank or coating concerns.

0/7 completePractice questions
Answer aloud, then open the preparation point.
1Show the last recorded substantial corrosion or structural repair.
Trace the finding through thickness data or inspection, defect report, class involvement, repair specification and closure.
2Which tanks or structural areas require enhanced monitoring?
Identify them from class reports, thickness trends, coating breakdown and the company's inspection programme.
3How do onboard tank inspections enter the Enhanced Survey File?
Show the controlled filing or cross-reference and how defects are escalated into maintenance, defect and class processes.
4What is the role of the Coating Technical File?
Use it to identify the approved coating system, application and repair history, inspection criteria and maintenance evidence.
5What visible signs would make you stop treating corrosion as routine maintenance?
Escalate cracking, deformation, leakage, wastage beyond criteria or rapid deterioration for competent assessment and class notification.
Where an observation may arise
Required survey, thickness, evaluation or repair records are missing.
A structural repair appears in one record but not in the defect, incident or class trail.
The Coating Technical File is incomplete or coating deterioration is absent from maintenance planning.
Class status, tank-inspection reports and repair history do not agree.
Accessible structure shows significant corrosion, cracking, deformation or leakage without documented action.
The responsible officers cannot identify areas under enhanced monitoring.
Past observations for practice
The last class attendance date did not match the date listed in the PIQ.
There was no company procedure requiring the coating technical file to be maintained.
The observed person was unaware of the requirement of having CTM file onboard.
Master's practical note
Start with the latest thickness-measurement and class reports, identify one suspect area, then trace it forward to the ship's own inspections. The file should explain the present steel condition, not merely preserve old survey paper.
Equipment boundary and references
Equipment boundary: This question applies to oil and chemical tankers subject to the Enhanced Survey Programme. Acceptance criteria, substantial-corrosion limits and survey scope belong to class rules and the ESP Code.
