This next equipment is most vulnerable to the environment since we are talking about the pollution to the water. Oily Water Separator (OWS) is critical on every ship and most of the authorities and this is their favorite to be inspected because the marine laws are stricter than before.

Environmental pollution is an incurable disease. It can only be prevented.
-Barry Commoner

Most of the company nowadays, this is the priority in terms of marine pollution with the others like carbon, sulfur and CFC emission to the atmosphere and garbage, sewage and bilge for the sea. You can read a lot of stories about marine pollution by tampering the oil content monitor or using a “magic” pipe to discharge any liquid to the sea then the authorities somewhat found this wrong doing by analyzing their position history and all the log book recordings.

The environment will continue to deteriorate until pollution practices are abandoned.
-B. F. Skinner

Companies now don´t tolerate in any way to do this in the future since this is totally destroying our environment and also big fine to authorities or worst will be jailed. Some unavoidable this is by accident like grounding on shore or wreckage to coral reefs which cause hull penetration and oil spillage to the sea.

If you maintain regularly your OWS, you don´t have to worry about the local authorities. Don´t hesitate to contact your company to ask help and advice if you have some trouble with the equipment or your bilge tank is full so they can arrange for shore disposal. Review the MARPOL book for this matter. Always remember your family waiting for you to get home.
