MEETING WITH SINGAPORE MPA - 3RD MAY 2001

Dr. Timothy Gunner, Technical Consultant to INTERTANKO, and Minerva Alfonso, the INTERTANKO Asian Representative, had a meeting with the Singapore Maritime Port Authority ( MPA) on 3 May 2001. The scope of the meeting was to discuss issues relating to bunkering in Singapore and particularly the revision of the Singapore Bunkering Code CP60.  Two major items are being undertaken for the revision of this code of practice; namely, the location for the taking of the bunker transfer sample where it seems that Singapore, one of the three current signatories to MARPOL Annex VI, is adopting the location as specified in the renegotiated supporting guidelines for Annex VI for the taking of the required retention sample - the Vessel's Bunker Manifold. 

The other item relates to the current practice as allowed within CP60 of air blowing of the bunker hose upon completion of bunkering.  The INTERTANKO delegation pointed out to the MPA that such a practice is dangerous as it ultimately introduces air into the hydrocarbon vapour phase in the bunker tank creating a risk of explosion (flammability range).  Pursuant to this the MPA agreed that it would propose a revision to this air blowing procedure from the revised CP60 and replace it with a "drain back" procedure for emptying of the bunker hose.  This step, it is believed, will outlaw the production of "cappuccino" bunkers with the associated financial and safety consequences. This result, when implemented by the MPA, would give an immediate return to shipowners. We have had numerous reports on experience with "cappuccino" bunkering in Singapore. According to reports from one member company, ten of their tankers had an average bunker shortage of 100 tons due to the misuse of the air blowing procedure. Simple arithmetic says that with the change in procedure the company would save some USD 180,000 (100 tons x 10 ships x 180 USD/t) or rather receive the 1,000 tons of bunkers they had paid for but which were never transferred to their ships.
