Until now most fenders involved in ship to ship transfers (STS) have been Yokohama manufactured and the record of incidents in STS has been unenviably high.

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 the ISO standard apparently seeks to lower this requirement. In addition, different fibres of an unproven nature are being proposed. It has also been suggested that the maker’s name should be clearly marked on the fender so that Masters can see that it is from a known manufacturer. 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. 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?” For further information, please contact
