–Machinery operations with potential to pollute

Some pieces of machinery can cause pollution when they malfunction. If you are assigned to engine room watch, be familiar with all the machinery and know the possibilities for oil pollution that can come from internal equipment problems.

Here are some examples:

  • All air compressors carry over a trace of oil into the compressed air receiver. This oil is removed by a coalescing filter. An air compressor with worn or incorrect seals can carry over large quantities of oil. The oil will then overwhelm the filter and be drained out with the condensed moisture in the air-cooler section of the air compressor.
  • Oil coolers and heat exchangers can pollute if oil seeps through a tube leak to the water side.
  • Oil can carry over into an inert gas scrubber and be discharged with the scrubber discharge.
