In May 2009, the Jan de Nul Group analysed the greenhouse gas emissions and the overall cleanliness of the ship’s engines. Immediately afterwards, the fuel of the dredger Manzanillo II was enhanced with XBEE Enzyme Fuel Technology, thereby proving the benefits of this diesel oil cleaner.
Gaseous emissions | Without XBEE | With XBEE | Difference (%) |
|---|---|---|---|
| Flow (Nm3/h) | 392.0 | 385.7 | -1.59 |
| Temperature (°C) | 367.5 | 361.7 | -1.56 |
| Excess air (%) | 132.45 | 146.15 | +10.34 |
| CO2(%) | 6.70 | 6.30 | -5.97 |
| CO | 79.50 | 66.50 | -16.35 |
| NO (mg/Nm3) | 735.50 | 633.25 | -13.90 |
| NOx (mg/Nm3) | 772.00 | 665.25 | -13.83 |
| O2(%) | 11.90 | 12.40 | +4.20 |
The tests were conducted under the direction of Freddy Devolder, fleet manager of Jan de Nul, on the main engines of the M/V Manzanillo II. The dredger is powered by two Pielstick 8PA6 L280 SEMT diesel engines, with a total power of 12,140 kW.
The results have been significant, with the XBEE bio-additive reducing CO2 emissions by 5.97%. Carbon monoxide was reduced by 16.35%. On the other hand, oxygenation was increased by 4.2% to improve combustion in both engines.
