Guideline for handling of fuel oil additive




Following are the guideline for handling of FO additive

Sludge dispersants

The Chief Engineer shall avoid the common use of a sludge dispersant unless any abnormality is discovered.

In preparation for an emergency, five drums of sludge dispersant shall be kept on board all the time.

When a sludge-dispersant is used, the Chief Engineer shall submit to the Technical Superintendent a detailed report on the abnormal condition and utilization condition (a copy to the Fuel Section).



Mold-preventive agent

A mold-preventive agent shall be put in A oil in the following manners to prevent generation of mold, since a recent increase in ships burning only C-oil causes generation of mold to increase because of longer onboard storage periods of A-oil.

The agent shall be put into the A oil storage tanks, settling tanks, and service tanks in accordance with maker instructions. Two years after the last application, an additional application shall be made in accordance with maker instructions.
