BP and Invensys Tackle Bunker Fuel Problem

Tuesday, November 20, 2007
The majority of bunker fuel is delivered to ships by barge. Trapped air, held in suspension within viscous bunker oil, artificially increases its volume. This effect has been a major and hitherto unsolvable problem for the shipping industry. The measurement of the supplied quantity currently involves dipping barge tanks before and after delivery and undertaking various calculations and corrections to convert the tank volume measurement into a delivered mass. This process is fraught with difficulties, errors and personnel hazards. BP, recognizing all these problems, has embarked upon an ambitious project to utilize best available and economically viable technology to overcome the traditional quantity verification methods. After extensive evaluation of all current flow measurement technologies, Invensys was one of three vendors able to meet the strict flow measurement requirements to develop a control system that will accurately measure the amount of bunker oil loaded onto a ship, excluding trapped air. This system will ensure that ship owners only pay for the mass of fuel that is delivered.

BP asked the three flow meter manufacturers to take part in a laboratory trial to determine the ability of their flow meters to accurately measure bunker oil. The criterion of the test was to measure the amount of oil by mass excluding any suspended air. The only product that was able to meet this strict criterion was the Foxboro CFT50 Digital Coriolis Meter, which was developed by Invensys in partnership with Oxford University. With over 200 million tons of bunker fuel delivered to ships each year, it is essential that the process of delivering bunkers is both fair and safe. This project proposes technology as the solution: not only can the delivered mass be accurately measured, but by use of the latest communications technology, the ship’s crew can “see” the fuel delivery data in real time without the need to climb down onto the barge, (a hazardous activity which has resulted in a number of fatalities). But bunkering is a wide-ranging activity, with stems (fuel deliveries) ranging from 300 tons to 12,000 tons. Flow rates vary, timing is often critical (to meet tides, for example) and the value of some deliveries can exceed millions of dollars. The measurement quality issue is of equal concern both to ship operators and to the International Bunkering Industry Association, (IBIA). Raising industry standards is one of the current themes of IBIA, who will be overseeing the setting of a new measurement standard for the global bunker industry.
