During the last years, INTERTANKO has continuously followed up the lists of tankers detained in European, Asian and North American ports

with the aim of:

  • gaining an insight into this problem and enable the Association to achieve its main goals of SAFE TRANSPORT, CLEANER SEAS AND FREE COMPETITION
  • helping its members achieve lower detention rates
  • addressing Port State Authorities with relevant issues
  • monitoring repeated offenders and if necessary reviewing/terminating the membership of members who have a pattern of serious port state detentions in accordance with the following criterion adopted by INTERTANKO’s Council

     INTERTANKO’s Executive Committee will review cases of repeated detentions of a Member’s tanker(s) to determine whether membership should be terminated or suspended. The Executive Committee will take into account the severity of the detention and the performance of the Port State Control. The member will have the right to appeal”.
  • helping the tanker industry and the public to achieve a better overview of tanker detentions

INTERTANKO is also assisting Owners subjected to unjustified detentions, which happen from time to time. It should also be noted that with the exception of USCG`s appeals procedure, there are no effective appeals procedures in place in the different MOUs.

By compiling the information provided by PSC authorities, INTERTANKO is now in a position to present a consolidated picture of all tanker detentions worldwide.

Aggregate Tanker Detention Statistics (Jan - Oct 2000)­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­

During the first months of 2000, the rate of tanker detentions deteriorated compared to the 1999 levels.  The deterioration was mainly due to the Erika effect and the increased focus on tankers, particularly during the early part of the year.  During the period January - October 2000, of the 2334 ships detained 233 were tankers. 68 of these vessels, or 2.9 per cent of the total, were tankers registered with INTERTANKO. This was a deterioration of the 2.0 per cent figure recorded for 1999 as a whole.



Detentions vs. Tanker Inspections 1999

By analysing the information published in the 1999 Annual Reports of the Paris MoU, Tokyo MoU and USCG, INTERTANKO has also been able to extract statistics on the relationship between the number of inspections and the number of detentions.

It is interesting to note that during 1999 a total of 248 tankers were detained out of 7,265 ships inspected.  Only 3.4 per cent of all tankers inspected by the three regimes were detained, as opposed to 6.7 per cent of all ships. It is encouraging to see that tankers in US waters have enjoyed the lowest percentage of detentions whilst being subjected to the highest number of inspections.


INTERTANKO’s database – Analysis of deficiencies

To assist members achieve lower detention rates, INTERTANKO has analysed the number and type of deficiencies that have led to tankers being detained. We are now able to provide aggregate information on the main problems, draw meaningful conclusions and disseminate this information to our members.

During the period January 1999 –June 2000, INTERTANKO tankers experienced a total of 100 detentions due to 276 deficiencies, i.e. more than one deficiency per detention.

It is important, and at the same time alarming, to note that almost 60% of deficiencies belong to one of the following categories:

  • Fire Fighting Appliances (particularly fire dampers)
  • Life Saving Appliances
  • Marine Pollution – Annex I (particularly oily-water separating equipment)
  • Safety in General
