Energy Conservation Efforts- burning of diesel and heavy fuel oil



It is internationally recognized that the burning of Diesel and Heavy Fuel Oil can result in many environmental impacts.

When fuel is combusted, pollutants such as the Oxides of Carbon, Nitrogen and Sulfur are emitted to the atmosphere.

These can contribute to the effects of Greenhouse gases and acid rain. This shall be mitigated by ensuring that:

a. The main and auxiliary engines are operated according to manufacturers instructions





b. The main and auxiliary engines are properly maintained as per the manufacturers instructions and the vessels planned maintenance system

c. Funnel exhaust is correctly monitored to ensure efficient combustion

d. Speed is correctly adjusted to avoid excess fuel consumption whilst staying within the parameters of the charterers requirements

e. Speed is reduced in heavy weather to avoid unproductive consumption apart from the safety aspect

f. The automatic pilot is correctly set to avoid frequent and excessive helm movements

g. The condition of the ships bottom is regularly inspected for signs of fouling or damage to coating

h. The condition of the ships propeller is regularly inspected for signs of damage

i. Ancillary systems, including lighting, ventilation systems, galley ranges, steam supplies etc are turned off when not required
