Ship Risk Profile


Every day a number of ships will be selected for a port State control inspection throughout the region. To facilitate such selection, the central computer database, known as ‘THETIS’ is consulted by PSCO’s. This information system, hosted by the European Maritime Safety Agency, informs national PSC authorities which ships are due for an inspection. Data on ships particulars and reports of previous inspections carried out within the Paris MoU region are provided by the information system as well.

Ship risk profile

Each ship in the information system will be attributed a ship risk profile (SRP), in accordance with Annex 7 of the Paris MoU text. This SRP will determine the ships priority for inspection, the interval between its inspections and the scope of the inspection. Ships can be “high risk”, “standard risk” or “low risk”. The profile is calculated using generic and historic parameters. Table 1 of annex 7 of the Memorandum shows the criteria within each parameter for each ship risk profile. A ship’s risk profile is recalculated daily taking into account changes in the more dynamic parameters such as age, the 36 month inspection history and company performance. Recalculation also occurs after every inspection and when the applicable performance tables for flag and R.O.s are changed. Calculate your own risk using the calculators on this website. Use the list of RO's meeting low risk criteria and the company performance as parameters in the ship risk calculator.


What is an IMO audit?

IMO audit means the Voluntary IMO Member State Audit Scheme (VIMSAS) according to IMO Resolution A.974(24). The audit is carried out by trained auditors under the auspices of the IMO.

Will changes made to an inspection report after an appeal effect the Ship Risk Profile (SRP)?

All changes made to an inspection report after recording in the Paris MoU Database THETIS will have an effect on all related issues, including the SRP. The calculation of the SRP is done by THETIS on the basis of the recorded information in the database.


Deficiencies marked as Accidental Damage are not taken into account for the calculation of the Ship Risk Profile
