The 19th meeting of ISTEC (INTERTANKO Safety, Technical and Environmental Committee) was held in Hydra on 21 September 2001. The meeting was also attended by the IACS Chairman, Mr. Igor Ponomarev, the Chairman of the Vetting Committee, Mr. Lars Mossberg, and INTERTANKO's Managing Director, Dr. Peter Swift.

The principal outcome of this meeting is summarised below:

Implementation of MARPOL Annex VI

INTERTANKO should lobby Governments to enforce MARPOL Annex VI within the due date. The Secretariat will prepare a brief memorandum, which will be circulated in our next Weekly News.

The Marine Safety Data Sheet (MSDS)

The Committee agreed that INTERTANKO should submit a document to the next MSC session requesting that the MSDS be made a mandatory provision under the SOLAS Convention. It will be recommended that MSDS be extended to bunkers and paints. INTERTANKO will solicit OCIMF and oil major companies' advice and co-operation.

VDRs (Voyage Data Recorders)

INTERTANKO will continue to work in co-operation with the Swedish, German, and Finish Delegations in IMO on the concept of a "reduced" VDR version for existing ships. The Committee also noted the proposal to submit to IMO requests for exemption from retrofitting VDRs to existing vessels that will be phased-out under the revised 13G.

IACS Members' standards for evaluating the structural strength of existing ships

The Secretariat had invited all IACS Members and Associate Members to explain the standards used for evaluating the structural strength of existing ships. Most Societies have responded and an analysis of these replies was provided to the Committee.

The general view was that there is a lack of consistency in Class Societies' methods of assessing the structural strength of ships changing Class. Some of them appear to rely only on the previous Class assessment/recommendations while others apparently perform a structural strength assessment, buckling included. There are also differences according to whether the ship is transferred from an IACS or a non-IACS member. In the latter case the ship needs a formal (gaining) class approval.

It was, however, agreed that INTERTANKO should seek further clarification from individual societies and continue this dialogue.

The IACS Chairman underlined the positive effect of the INTERTANKO initiative. This had encouraged IACS to look more closely at the common standards for assessing structural strength and also prompted an IACS' action for the unification of scantling calculations.


A very open discussion ensued regarding current and past standards for quality ship design, with the emphasis placed on how we can ensure that quality vessels are built by the shipyards and certified by Class. The discussion addressed two topics:

Standards for newbuilding - It is important to note that INTERTANKO does not imply that new tankers are not properly built. However, the newbuilding demand for the next 10 years, imposed by the revised MARPOL 13G regulation, will require better quality control throughout the whole process, i.e. design and construction. This is extremely important for tankers because they are subject to an increased environmental performance. Thus, future standards need to be reviewed and possibly made more uniform. This can only be done by having a thorough assessment together with Class Societies and shipyards.

b) INTERTANKO Newbuilding Guideline 2001 - In parallel with the above complex action with regard to newbuilding standards, INTERTANKO intends to develop an awareness guide aiming to include current good practices for newbuilding specifications.

The Committee identified some of the key elements that are important for the raising of standards and quality as follows:-

  • Corrosion Margins
  • Coatings and their application
  • Fatigue analysis, 20,30,40 years?
  • Access for inspection purposes
  • Guarantee period and subsequent maintenance. Yard, Class, Owner
  • Owners Supervision during construction
  • The ability to select Class
  • Sub-contractors and their inspectorsOperational Efficiency
  • Quality Standards
  • Hull Warranty
  • Mechanical Parts warranty
  • Crash testing
  • Other warranties
  • Commonising of trading areas
  • Testing of ALL lifeboats whilst at the yard.

Other areas of concern that were raised pertained to the following

  • Emergency Fire Pump location and suction position which shipyards currently position for lightly ballast draught and NOT all loading conditions, resulting in circumstances in which the vessel cannot get suction to the emergency fire pump, although Class approved.
  • INTERTANKO should work with Class in a Bi-lateral agreement as we are a market force and set the standards to ensure that the yards deliver what the owner needs in the way he needs it
  • The Industry is ready to accept changes as and when strides in quality are agreed.

There remain many other areas to be addressed and ISTEC has recommended that in addition to the above:

  • The Documentary Committee should consider a shipbuilding contract and identify other areas of concern to owners.
  • The Vetting Committee could suggest additional items that would make a newbuilding "vetting friendly"

OCIMF new requirements for strength of mooring tests

OCIMF is in the final process of producing a document entitled 'Recommendations for Ships' Fittings for Use with Tugs (With particular reference to Escorting and other High Load Operations)' The Committee noted that so far not all of INTERTANKO's concerns and comments had been taken into account by OCIMF. ISTEC would, however, be positive to further discussions with OCIMF on this matter.
