Further to last week’s Weekly NEWS No 06/2000, unfortunately there was an error in the first sentence of the article. The words “unenviably high” should have read “enviably low”. We apologise to our readers for any inconvience this error may have caused.

The corrected article is repeated below  

Until now most fenders involved in ship to ship transfers (STS) have been Yokohama manufactured and the record of incidents in STS has been enviably low. An ISO standard for fenders is now being prepared by the International Standards Organisation and the door appears to be opening for variable standards. The OCIMF Guidelines on STS transfer lay down a standard for the pneumatic pressure of the fender and some of the manufacturers participating in writing the ISO standard apparently seek to lower this requirement. In addition, different fibres of an unproven nature are being proposed.  This has direct implications on the allowable elongation, factors of safety and eventual burst pressure of the fenders.

It has also been suggested that the maker's name , unit's initial pressure and size should be clearly marked on the fender so that Masters can see that it is from a known manufacturer and gauge the available performance accordingly.  There are indications that other lower specifications are coming onto the market and since a number of STS take place on an "ad hoc" basis, it would be good if the same proven quality were uniformly available. INTERTANKO would like to hear from members with experience and preference in this area of STS to assist in developing input to the ISO committee. Copies of the draft ISO standard can be sent to interested parties. The next meeting of the ISO committee takes place 26.2.2000 at which time a decision will be taken on the final draft spec to be sent to all member countries for voting.  Your prompt response will therefore be appreciated. In the meantime it may be that there is yet another item for the Master's STS checklist, if not already there. "What assurance has been given of the quality and effectiveness of the fender?"
