Ship Risk Profile

Targetting:

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 are assigned high, standard or low risk. This is based on 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 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.

FAQ:

What are the criteria for the calculation of the Company Performance and how are these taken into account?

The Company Performance is calculated as follows:
Company performance takes account of the detention and deficiency history of all ships in a company’s fleet while that company was the ISM company for the ship. Companies are ranked as having a “very low”, low, medium or high” performance. The calculation is made daily on the basis of a running 36-month period. There is no lower limit for the number of inspections needed to qualify except a company with no inspections in the last 36 months will be given a “medium performance”. The formula consists of two elements, the deficiency index and the detention index.

Deficiency Index 

When counting deficiencies each ISM related deficiency is weighted at 5 points. Other deficiencies are valued at 1 point. The Deficiency Index is the ratio of the total points of all deficiencies of all ships in a company’s fleet to the number of inspections of all ships in the company’s fleet within the last 36 months. This ratio is compared with the average for all ships inspected in the Paris MoU over the last 3 calendar years to determine whether the index is average, above average or below average as follows:

Deficiency index                       Deficiency points per inspection

Above average                                > 2 above PMoU average

Average                                          PMoU average ± 2

Below average                                > 2 below PMoU average

Detention Index 

The Detention Index is the ratio of the number of detentions all ships in a company’s fleet to the number of inspections of all the ships in the company’s fleet within the last 36 months. This ratio is compared with the average for all ships inspected in the Paris MoU over the last 3 calendar years to determine whether the index is average, above average or below average as follows:

Detention index                              Detention rate

Above average                                 > 2 above PMoU average

Average                                           PMoU average ± 2%

Below average                                 > 2 below PMoU average

 

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
