MARPOL 73/78 Laws Guiding OWS
Oil water separator ( OWS ) is a useful tools for separating oily bilge waters to avoid water pollution.
On this article, we are going to look into MARPL 73/78 laws guiding OWS. Lately 70’s , most ocean going ship directly pump out oily waters into the ocean, which eventually flow down to the shore side, creating a large pollution also eliminates marine animals etc. The MARPOL 73/78 Annex I law which came into force in 1973 created a commendable records by reducing act of polluting the waters.
This law which was amended in 1978 added more positive and advanced technology to help the ship operators to control the water pollution. All sea going vessels were equipped with OWS , to help separate the oils mixed with water before pumping overboard. It was also added with penalties to any ship that engages in pumping oils, chemicals, etc which may cause water pollution.
This laws was somehow manipulated by most ship operators by showing working OWS , but never use them. More advance in the equipment was added in 1993, which adds micro sim, three ways valves, etc.
The micro sim records and save all operations, which were carried out via OWS. This gives more opportunities for the port control inspectors to check operations carried out with this equipment. Following the oil record book, which should be carefully record as per the law recommended way. This includes, recording each tank level, time & date of transfer, the officer who was in charge during the operation, period in when OWS were used , location, etc.
Recently it’s very important and dangerous for any ship operator to pump out oily water higher above 15 PPM. Previously, test of this equipment were carried out only on checking the 15ppm alarm but in the recent time. After 1993, inspectors can be able to check the equipment by recycling the water through the help of three way valve. This help in pass the water from tank to tank without sending it overboard while in port.
It’s important for every ship officers read and understand the IMO resolution MEPC 60(33) for oil content meters in accordance with MARPOL 73/78 Annex I. This will save you from landing yourself into jail or fines.
