Harmonized System of Survey and Certification (HSSC)
HSSC connects surveys and certificates under the instruments included in the system. Identifying the document, survey type, dates and evidence allows the programme to be coordinated while retaining each certificate’s distinct requirements.
Operational Explanation
The harmonized system organizes surveys and certification under the instruments included in it. It connects initial checks, verification during the certificate’s life and renewal, using dates and windows that allow attendances to be coordinated. One attendance may cover several documents, but the programme must show which requirement and outcome belong to each.
Build the calendar from actual certificates and their anniversary dates. The five-year cargo cycle must not be transferred to the passenger safety certificate, which retains annual renewal. A coordinated attendance must still cover every required scope.
| Survey type | Main question within the certificate scope |
|---|---|
| Initial | Do design, construction/installation and documents meet requirements before first issue? |
| Annual | Have the items been maintained and do they remain satisfactory for service? |
| Intermediate or periodical | Do the specified items satisfy the checks prescribed by that regime and stage of the cycle? |
| Renewal | Do examinations and documents support issue of the new certificate? |
The table distinguishes questions; it does not assign every survey type to every certificate.
Regulatory Reference
IMO A.1207(34), HSSC 2025. IMO: HSSC. Individual Convention provisions determine applicability and validity.
HSSC 2025, §§1–3, distinguishes survey types and certificate requirements. The combined Cargo Ship Safety Certificate retains the checks of the certificates it replaces and the pertinent endorsements (§3.7). The anniversary date is the day and month corresponding to certificate expiry: check any authorised changes rather than calculating it from the booking. HSSC 2025 — A.1207(34).
Scope of Application
Distinguish cargo and passenger certificates and annual, intermediate and periodical surveys. Cargo Safety Radio uses periodical surveys; instruments outside HSSC retain their own regime.
Procedure / How to Complete It
- Identify the certificate, anniversary date and survey due.
- Record window opening and closing and agree the programme.
- Prepare previous reports, modifications, maintenance and open defects.
- Arrange safe access and tests against the agreed scope.
- Check outcome, certificate endorsement and deadlines for required actions.
The matrix can use one row per certificate and survey: applicable instrument/basis, document identity, expiry and anniversary, window, items and tests, competent party, report/outcome and endorsement. It is a working tool, not a mandatory IMO form. For shared attendance check each row before marking the programme complete.
Practical Example
List Construction, Equipment and Radio separately in the calendar even when attendance is arranged in the same port. Check the report, outcome and required endorsement for each.
If the summary says only “survey completed”, the matrix must still show which rows are complete. A Radio report does not establish the Equipment outcome; obtain the pertinent results and endorsements before closing the calendar.
What Typically Goes Wrong
Treating printed expiry as the only relevant date or using an extension as an ordinary planning allowance.
Common Mistakes Mistake Library
| Mistake | Consequence | How to avoid it |
|---|---|---|
| Use only printed expiry | An annual, intermediate or periodical survey may remain incomplete within its window. | Record the certificate, anniversary, survey type, window and separate outcome. |
| Use an extension as ordinary planning allowance | The programme may depend on authorisation that has not been granted. | Plan before expiry and verify the conditions, authorisation and limits of each extension. |
| Close several certificates with one unreconciled report | A scope or required endorsement may remain uncovered. | Connect each requirement and outcome with the relevant document, including during shared attendance. |
