TMSA: the Company's self-assessment, not the ship's
The OCIMF scheme by which the Company measures the maturity of its own management system: 13 elements, 266 KPIs, four levels. It is not mandatory, but since 2017 it lives inside SIRE, and charterers read it alongside the inspection reports for the same fleet.
Operational Explanation
Tanker Management and Self Assessment is the scheme by which OCIMF asks the Company to measure the maturity of its own management system. Two things set it apart from everything else in this module: it is not an inspection, because nobody comes on board to verify it, and it is not about the ship, but about the organization that runs it. One self-assessment covers the operator's whole fleet.
The structure is a grid: for each element the Company declares whether it meets a set of key performance indicators, and the level attained runs from Level 1, the minimum expected, up to Level 4. The OCIMF programme page describes it as “the minimum standard expected (level 1) plus three levels of increasing standards or performance”. The point is not to reach four everywhere: it is to know where you stand and to declare it with documentary evidence.
Since February 2017 the TMSA programme has been incorporated into the SIRE programme: the self-assessment no longer lives in a separate archive but alongside the inspection reports for the same fleet. That is why a charterer can read what the Company says about itself and what an inspector found on board side by side.
Regulatory Reference
No binding instrument requires TMSA. It is not convention law, it is not a flag requirement and it is not subject to Port State Control: it is a voluntary scheme published by OCIMF, and what makes it effectively unavoidable for anyone chartering to oil majors is the market, not the rule. The obligation underneath it is a different one: the ISM Code, which requires the management system. TMSA measures it against an industry benchmark; it does not replace it.
The current edition is the third, OCIMF publication page: TMSA 3, published on 10 April 2017. The first edition dates from 2004, the second from July 2008.
The TMSA3 FAQs published by OCIMF in April 2017 set out what changed with the third edition, and are the source of the figures that follow:
- 13 elements. The third edition added Element 13, Maritime Security, in these words: “Added a new element: Element 13 – Maritime Security”. The numbering runs from 1 to 13, but Element 6 is split into 6 and 6A: there are fourteen assessment sheets and thirteen numbered elements.
- 266 KPIs, of which 85 were introduced with this edition and 19 more than in TMSA 2. Twenty-five KPIs were moved from a higher level to a lower one (from 4 to 3, from 3 to 2): what used to be excellence has become the baseline expectation.
- The “not applicable” option was removed. If the Company considers that a KPI does not concern it, it answers yes stating and justifying the reason with documentary evidence; answering no makes the system record the element as incomplete.
- Element 10 renamed Environmental and Energy Management, previously Environmental Management, and expanded content in Elements 6 and 6A covering cargo, ballast, tank cleaning, bunkering, mooring and anchoring.
A discrepancy between two OCIMF documents, reported in full. The April 2017 FAQs announce that “from 1 January 2018, only TMSA3 will be available”. The later OCIMF presentation on the TMSA programme states instead that from 9 April 2018 all TMSA reports created or published within SIRE must be in the TMSA 3 format. The first is the announced deadline, the second the one actually applied: both are reported here with their source, rather than picking one.
Scope of Application
Every tanker vessel technical operator that joins the programme. OCIMF states that TMSA 3 can be used worldwide, including coastal and inland vessels and barges: it is not a scheme for large ocean fleets alone. The annual subscription is GBP 50 per operator.
Participation is voluntary in the strict sense and compulsory in the practical one: a company without a published TMSA is not breaking any law, but it drops out of the list of those a charterer requiring that document can assess.
Procedure / How to Complete It
- Assign each element to someone with access to the evidence: TMSA is not filled in by the quality department on its own.
- For each KPI, identify the document that proves it first and answer second: the reverse order is where declared but unsupported levels come from.
- Where a KPI does not apply, answer yes with the reason written down and evidenced: the “not applicable” box no longer exists.
- Publish the self-assessment in SIRE and review it annually, as OCIMF recommends.
- Update it off-cycle whenever something substantial changes: management structure, safety management system, fleet size or composition.
Practical Example
A Company declares Level 4 on management of change. A charterer opens the TMSA alongside the SIRE reports for the same fleet and finds, on two ships, observations about plant modifications carried out without documented assessment. The declaration is not false in the abstract — the procedure exists — but the declared level does not hold against evidence sitting in the same archive. Since 2017 the two documents live in the same programme, and the comparison costs one click.
What Typically Goes Wrong
Common Mistakes Mistake Library
| Mistake | Consequence | How to avoid it |
|---|---|---|
| Levels declared before the evidence is collected | Visible gap between TMSA and SIRE reports for the same fleet | Start from the document that proves the KPI, not from the desired answer |
| Self-assessment treated as an annual exercise | A score that does not reflect changes in structure or fleet | Update at every substantial change, not only at the deadline |
| KPIs deemed not applicable without documented justification | Element recorded as incomplete by the system | Answer yes with reason and evidence: the “not applicable” box is gone |
What the PSCO Checks
Operational Tips
- Keep the KPI → document map on a single sheet: it is what turns an update into an hour's work instead of a week's.
- Read the twenty-five KPIs moved down a level: they show where the industry raised the minimum expectation, and that is where ground is lost without anyone noticing.
- Compare your TMSA with the SIRE observations for your own fleet before a charterer does: they have been in the same programme since 2017.
- Element 13 on maritime security covers cyber security too: it is not a chapter for the security officer alone.
Preparation checklist
Study checklist. This summary is for study and preparation. It does not replace the Company's Safety Management System procedures or the official text of the regulation.
- Every element assigned to someone with access to the evidence
- KPI → evidence document map kept up to date
- Non-applicable KPIs justified in writing and documented
- Self-assessment reviewed within the last twelve months
- Update carried out after the latest change of structure or fleet
- Declared levels compared with the fleet's SIRE observations
