▸ Treatment and discharge of contaminated bilge water
to a reception facility.
▸ For biological contamination, treat bilge tank(s) with
a biocide.
▸ Hot water flush of OWS clean out tanks
and piping that have sludge build-up.
▸ Cleaning
of bilge and other affected areas to remove sludge and rust.
▸ Segregate soot from entering bilge (capture cleaning
residues) and divert from the bilge. Repair exhaust leaks.
▸
Keep rust from ageing machinery and fittings from entering bilge.
▸ Tank coatings and pipe condition play a major role in
the operation. Focus on bilge water sources and utilization of composite
pipe materials to prevent issues caused by corrosion. Tank coatings
should also be examined and maintained. This is particularly important
in low point collections areas.
▸ Segregation of
nutrient and contamination sources: Check for and replace leaky sewage
and cooling (sea suction) pipes.
▸ Retrofit modular
post-OWS (before but not in line with (i.e. full flow) the OCM) particle
filters.
▸ Pre-treat soot containing [cleaning]
water before entry to bilge or segregate sooty water resulting from
machinery cleaning.
