What if there is excess water content in bunker fuel ?
The level of water in bunker fuel is normally low, about 0.1-0.2%
The introduction of water can originate from a number
of sources, including:
• Tank condensation
• Tank leakage
• Heating coil leakage
• Deliberate injection
Even though not a normal procedure, it is possible at least to obtain
indications or traces of water in the delivered fuel by use of water
paste; if water is detected, a letter of protest should be issued stating that traces of water in the fuel have been found. The actual
amount of water present can normally only be established when
the water has settled down at the bottom of the fuel tank, a day
or so after delivery.
Normal levels of water in the fuel are usually drained from the
ship’s settling tanks with the remaining water being removed by the
purifier and centrifuge. Most ship’s can comfortably handle fuel oil
with water content up to about 2% before the purifier.
