I came across
US Coast Guard Prevention Blog the other day looks like it is a worthwhile site and I have added it to my blogroll.
I have a small beef with one paragraph from the post
Catching Polluters: Marine Pollution Enforcement—Part 1
The handling of oily waste is a constant challenge because it is continually produced, and the operation and maintenance of pollution prevention equipment takes time and effort. Additionally, disposal options can be costly. This has led some vessels to discharge oily waste overboard in direct contravention of MARPOL requirements.
Often inspectors assume that a ship produces far more waste oil then it can dispose of or that it is easier to pump oil over the side then it is to disposed of it legally.
Depending how the ship is set up this is not necessarily true. If the ship is set up right the easiest method to handle waste oil is send it to the waste oil tank, decant any water and burn the oil in the incinerator. Jury rigging the system to pump oil directly over the side would be far more effort. In addition a well designed engine room will have more capacity to burn oil in this fashion then is produced.
Think of your toilet at home, have you ever considered removing the waste and disposing of it illegally? No, because it is much easier to give the lever a push.
Aboard a newer, modern ship, Port State Control officers should not necessarily assume that illegally pumping oil over the side is the practical or desirable option for the crew.
