General explanation for TWI Figures
- The TWI table has the upper and lower limits of 40 and 62. An increase of 22 points in the TWI
represents a saving of 27.9% on the fuel cost. If fuel cost constitutes of 60% of operation cost this will be
a saving of 16.74% on operations cost. This also means that the price differential in bunker fuels should
have a spread of 27.9% based on the TWI.
- The FuelTech instrument does not record ECN values less than 18.7 since the fuel is considered to have very poor Ignition and Combustion properties. Therefore, ECN values hit a plateau on the lower end. At the upper end they go upto 35 and rarely up to 45. Nevertheless, there is sufficient range from 18.7 - 35 to address this variation in Ignition and Combustion properties of the fuel.
The best fuel in THE MIDDLE EAST has a TWI of 66 and the worst fuel in ANTWERP has a TWI of 52.<br /> If the fuel cost in the THE ANTWERP - ROTTERDAM area is $ 247.00.00/MT, it should sell in THE MIDDLE EAST<br /> for $ 285.87 - 295.87/ MT (by applying a price spread of 17.76 %) not taking in account any other logistics cost.
