Ship inspection database and rates

We maintain a database which assists us to calculate the risk factor of a ship. This lets us target high risk ships for inspection.

Ships become eligible for inspection every six months, however if deemed necessary, we may reduce this period. Our targeting system prioritises inspections primarily based upon a calculated risk factor.

To assist our marine surveyors in doing port State control (PSC) inspections, we use a ship inspection database. This database contains information received from various sources on a large number of ships. This information includes general particulars of a ship, PSC inspection history, including from the Indian Ocean MOU and Tokyo MOU.

Our Shipsys database uses this data to calculate the probability of a ship being detained, expressing the result as a percentage which becomes the risk factor. It is this risk factor that allows us to target high risk ships and inspect as required.

Ship eligibility and selection for PSC inspection

Selection of a ship for inspection depends upon a number of factors, including:

  • environmental risk
  • ship complaints
  • our risk-based ship inspection targeting scheme.

Ships become eligible for inspection every six months, however if deemed necessary, we may reduce this period. Our targeting system prioritises inspections primarily based upon a calculated risk factor.

Target rates

We prioritise high risk ships and base our decisions to inspect or detain on these priorities and other factors determined by our inspectors professional judgement as well as the database.

Priority group

Probability of detention (risk factor)

Target inspection rate

Priority 1

More than 5%

80%

Priority 2

4% to 5%

60%

Priority 3

2% to 3%

40%

Priority 4

1% or less

20%

While we work to these target rates, if we determine your ship needs to be inspected initially or in detail, reported as deficient, detained and/or fined, we maintain the right to do so based on our inspectors professional judgement, the law and the conventions that we work to.

You can contact us with questions about target rates by emailing psc@amsa.gov.au.
