Singapore, the world s biggest bunkering port, intends to eliminate the "cappuccino effect" in ship fuelling by using meters created to prevent suppliers from short-changing customers. The Maritime and Port Authority of Singapore, which sold more than 42 million tons of bunker oil in 2013, will be the world's first port to require the use of mass flow meters for fuel oil bunkering. The meters show the actual amount of fuel delivered, preventing suppliers from boosting their profits by injecting air into the fuel as it is pumped aboard. The "cappuccino effect" is so common that bunker tankers can charge ships less for fuel than the price they pay for lifting the fuel from on-shore oil terminals.
