Cappuccino Bunkers: Bunker deliveries at Singapore contain excessive amounts of air
Air causes the fuel to "foam" - unreliable measurement It has come to the UK P&I Club's attention that some bunker deliveries at Singapore have contained excessive amounts of air. As a result the quantity of fuel delivered and received was significantly overstated. This effect is termed "Cappuccino" as the entrained air causes the fuel to "foam" which makes traditional manual measurement at the time of delivery unreliable. After a few days the foam tends to collapse and tank measurements then show a significant "loss" of fuel. The following guidelines have been compiled to assist ship's crew with identification of this potential problem and hopefully help with dispute resolution.The following precautions should be taken when the bunker barge arrives alongside the receiving ship;1.Under the Singapore bunkering procedure safe access to and from the delivery barge is to be provided by the ship. This may comprise an accommodation ladder or pilot ladder or a combination of both.

This should be done even if an independent Bunker Surveyor ...
