If the oil-in-water content in the EGC drain tank exceeds 15 ppm, oil removal by
means of a water treatment unit is then required. Otherwise, if the oil-in-water
content of the water in the EGC drain tank does not exceed 15 ppm and the
vessel is operating outside an area of restricted overboard discharge, the water
can then be directly pumped overboard. Figure 4-58 provides a sketch of the
iCER drainage system for installations with gas and diesel Tier III mode opera-
tion.

Alternatively, an iCER drainage system with two separate water treatment units
can be considered. One unit handles the bleed-off water and the SAC drain water
(during iCER operation), the other handles the EGC circulation water as shown
in Figure 4-59,  4-99.
